Geothermal Innovations, Part 2: Stimulating Reservoirs in the Field and Partnerships in the Industry


Geothermal Innovations, Part 2: Stimulating Reservoirs in the Field and Partnerships in the Industry


By Leslie Blodgett, GEA
21 November 2012   |



WASHINGTON D.C. -- The U.S. geothermal industry's recent innovations contribute to increasing potential for the use of geothermal to power the renewable energy future, but high upfront risks and costs of development are one reason geothermal needs federal funding programs to expand.

“Federal and state incentives help attract investors to geothermal projects, and are essential to overcoming the obstacles facing the industry today.  But, with continued growth and innovation, the cost and risk of projects should decline as the industry expands and technology improves,” according to Geothermal Energy Association (GEA) Executive Director Karl Gawell.

The 2005 Energy Policy Act provided new geothermal power plants the same tax incentive as wind projects: US$ 0.02 per kilowatt hour produced during each of the first ten years of production.

Well-known in the geothermal world is a report from the Massachusetts Institute of Technology (MIT) conducted in 2006, which arguably helped to usher in a focus on research for EGS.  "The Future of Geothermal Energy, Impact of Enhanced Geothermal Systems for the 21st Century” stated that EGS could provide the United States with about 100 gigawatt-equivalent of domestic capacity in the next 50 years.

Also of note was a 2010 workshop on “Exploration and Assessment of Geothermal Resources” in which The Great Basin Center for Geothermal Energy (GBCGE), the DOE Geothermal Technology Program office (DOE-GTP) and the GEA invited geothermal professionals to discuss the state of knowledge of exploration for geothermal resources.  The discussion revolved around exploration techniques in areas of Geology and Structure, Geophysics, Remote Sensing, Geochemistry, Temperature Distribution, and Reservoir Characterization.

An understanding of geology is essential to the development process.  In Part 1 of this two-part look at geothermal technologies, the Geothermal Energy Association (GEA) examined some of the techniques and tools that are facilitating progress in geological testing and analysis for conventional and EGS geothermal projects.

Against this backdrop, GEA asked how DOE-funded geothermal projects are doing in a Q&A with the Department’s Geothermal Technologies Program’s Team Lead for Hydrothermal & Resource Confirmation Hildigunnur Thorsteinsson:

GEA: From DOE’s standpoint, what advancements have been made in EGS since the MIT Report and why is EGS a big part of the portfolio in advancing geothermal technologies?

DOE: "At the Department, we see geothermal energy, all the way from conventional hydrothermal resources to EGS, as an important part of an all-of-the-above energy strategy that develops every available source of American energy.

"While EGS has great potential to provide a large, clean, baseload, energy resource it can also help facilitate geothermal development outside of traditional hydrothermal areas in the western United States by extending geothermal energy production to additional areas in the country.

"Building off the findings of the MIT study, we have worked with industry and university partners to enhance our understanding of the subsurface through advanced modeling and simulation methods.

"Energy Department research in safe, efficient stimulation and monitoring methods has helped advance a number of EGS demonstration projects. For example, through a DOE funded EGS demonstration project, Calpine was able to successfully create a new EGS reservoir by increasing permeability and connecting multiple wells in the north-west part of The Geysers field.

"In addition, the DOE-funded AltaRock EGS demonstration is scheduled to initiate stimulation at their innovative EGS demonstration project in Oregon."



The projects that GTP accepts in its funding programs represent some of the some of the most creative geothermal innovations happening today to help bring the industry on a competitive track with other alternative energy options.

The Department’s broader efforts for geothermal are to lower its development costs and reduce the technical and market barriers to increased production in the United States, Thorsteinsson told GEA.

“Removing these barriers will ultimately strengthen the economic viability of geothermal development, and help provide a clean, renewable and reliable baseload resource for American homes and businesses,” Thorsteinsson said.

GEA: How will current GTP projects help to mitigate costs for the industry at large?

DOE: “The Geothermal Technologies Program is supporting a variety of projects aimed at prudently, safely and cost-effectively developing geothermal resources in the United States. As an example, we have supported research on the viability of using small-diameter core holes rather than full-diameter wells as exploration holes. This research is now paying significant dividends in the industry, helping to lower exploration and drilling costs for U.S. geothermal developers.

“Today, the Department is investing in several promising technologies to help further reduce costs,” she added. “For example, we are supporting an R&D project on percussive drilling technology that has the potential to significantly increase the rate of penetration in wells. This technology has been used with great success in mining and the project team is looking at ways to adapt the technology to the downhole environment of a geothermal well.”

Small-diameter core holes and percussive drilling technology are just two areas of further research being carried out by DOE partners.

Thorsteinsson hailed the work of James Faulds of the University of Nevada-Reno.  “At the recent Geothermal Resource Council meeting in Reno, our office recognized [Faulds] with the 2012 Peer Review Excellence Award for his team’s great work in characterizing structural controls of Enhanced Geothermal Systems (EGS) and conventional geothermal reservoirs.

“We look forward to working with our industry, national laboratory and university partners to continue these important research and demonstration projects,” she said.

Faulds is halfway through work on "Characterizing Structural Controls of EGS and Conventional Geothermal Reservoirs,” which won a $1 million DOE award to characterize geothermal potential at nearly 500 sites throughout the Great Basin.  “We want to help the industry achieve acceptable levels of site-selection risk ahead of expensive drilling,” Faulds was quoted on the university’s news site.

Thorsteinsson said, “The University of Nevada-Reno team is conducting important research to help characterize structural controls of EGS and conventional hydrothermal reservoirs, strengthening our modeling capabilities and helping identify new resources at a lower cost.

“Over the past year, this team has defined an array of favorable structural settings for geothermal systems and has completed a preliminary catalogue of structural settings for Great Basin systems,” Thorsteinsson added.  “As the project continues, we look forward to furthering our understanding of structural controls and models for a range of geothermal activities.”

Reporting on their 2010 exploration and assessment workshop, GBCGE, GTP and GEA found more work is needed on detailed structural models in the Great Basin and beyond, such as the Cascades, Rio Grande Rift, Snake River, and Imperial Valley.  Fault control of fractures and permeability are key features that need to be particularly understood, they found.

“What Jim Faulds brings to the table is a great understanding of structural geology and structural styles in geothermal systems, helping to identify, for example, zones of tension and associated permeability between fault strands,” said Ann Robertson-Tait in a recent conversation with GEA.  Robertson-Tait is a geologist and the Business Development Manager for GeothermEx, a long-established geothermal consultancy that is now part of Schlumberger, the global oilfield services company.


Thorsteinsson (DOE Geothermal Technologies Program) addresses attendees at GEA's National Geothermal Summit, August 2012; Robertson-Tait (GeothermEx) is second from right.
Geothermal fluid flow along faults is a concept that has been around for a long time, based on the common observation that hot springs are located along or near fault traces.  “The idea was that the fluid was rising from great depths all the way to the surface along a fault plane, but that model has been fairly well shot down in all but a few cases,” Robertson-Tait said.  “There is clearly a relationship between faults and hot springs, but this is a relatively shallow phenomenon.  What’s more important to geothermal developers are the controls on permeability and fluid flow at depth.  These controls are more complicated to resolve, and often involve a combination of permeable stratigraphic horizons and faulting.”

Developing Fracture Networks in Nevada

Brady’s Hot Springs in Nevada is a good example.  “The hot springs in this field are clearly occurring along a fault trace,” Robertson-Tait noted.  Ormat Nevada Inc., the operator of the Brady’s geothermal project, is the recipient of DOE funding at this field for an EGS project aimed at improving permeability in one or two marginal wells.  In the course of this project, Ormat has worked with Jim Faulds, GeothermEx and others to reinterpret the geology.  “This work has revealed that localized extension has created a series of faults, each with relatively small offset, creating a stretched-out zone of permeability.  This work has changed the conceptual model of the Brady’s field,” according to Robertson-Tait.

DOE has provided a $3.4 million grant for work on developing fracture networks at Brady’s, which has a stress environment and rock formations that are favorable for permeability enhancements.  The Brady’s site is located near Ormat’s Desert Peak geothermal project, which has also received DOE-funding for well improvements using EGS techniques.

An interactive, real-time map of seismic activity at Desert Peak and Brady's Hot Springs is viewable on the Lawrence Berkeley National Laboratory (LBNL)’s Earth Sciences Web site.

Predicting Permeability at LBNL

LBNL‘s Energy Resources Program enables geothermal energy development research.  The LBNL program looks to reduce uncertainties associated with finding, characterizing, and evaluating geothermal resources.  The program seeks to significantly increase production of geothermal resources through understanding the development and enhancement of permeability and fluid flow for EGS, according to its Web site. 

The LBNL is developing a reliable system to help predict reservoir temperatures through its DOE-funded “Integrated Chemical Geothermometry System for Geothermal Exploration” project.  The goal is to enable prediction of geothermal reservoir temperatures using chemical analyses of spring and well fluids.

Scientists can then “leverage geochemical data from multiple locations, aimed at providing a more reliable assessment of target reservoir temperature over traditional chemical geothermometers,” Thorsteinsson said.  “By enhancing our ability to assess reservoir temperatures, this research is helping industry better understand resource potential and reduce the costs of project development.”

Robertson-Tait said that the chemical and geomechanical elements of numerical modeling codes are important, especially for EGS.  While the codes are now becoming available largely out of the National Labs, there are also commercial codes that have these capabilities.  “Many of these codes handle issues that are particularly important in EGS, and I think that’s a good development.  DOE funding to the National Labs has gone a long way, and there are commercial codes too, an atmosphere that combines research and competition.”

GEA: What other innovations look promising?

DOE: “Across our different projects, the Department’s Geothermal Technologies Program is helping to conduct research and develop new technologies that reduce the cost of geothermal energy development and improve the efficiency of operations.  This R&D has not only advanced more cost-effective and innovative production technologies that are being used in the field today, but also sophisticated resource characterization and protective environmental practices that are building a sustainable industry for decades to come.

“Throughout this work, we continue to look for new ways to lower costs and improve operations.  For example, we conduct a technology road-mapping exercises to determine the most promising technical pathways for producing geothermal energy, including developing advanced geophysics and geochemistry tools and leveraging remote sensing.”

DOE’s roadmapping efforts should speed the permitting process for potential awardees, improve project costs, and lessen investor risk.

Additionally, the DOE’s new Transparent Cost Database contains thousands of estimates from more than 100 published studies and DOE program-planning or budget documents, part of ongoing road-mapping efforts for various technologies.

GEA: How are geothermal technologies similar to oil and gas technologies, and how are they different?  How does this help or hurt the industry?

DOE: “Many of the technologies and tool advancements made in the oil and gas industry can be beneficial to the geothermal community; equally, technology developments and discoveries made in geothermal can often be used in oil and gas.  In fact, early research at the Department of Energy on directional drilling and drill bit technologies is now used in both the geothermal and natural gas industries.

“However, geothermal environments typically have higher temperatures and harder rock than traditional oil and gas plays, so we are partnering with industry to develop new technologies that can operate effectively and safely in this unique environment.”

The 2010 exploration and assessment workshop reported that exploration system models are in the earliest stages of development, where mining or oil and gas were 50 or more years ago.

Funding for Geothermal Technologies: 2006-?

Congressional representatives may not know the exact differences between producing oil and producing geothermal, but a looming expiration date exists on federal tax incentives.  While geoanalysts do their part to decipher charts and readings, short-term expiration dates on tax credits translates to bad timing for geothermal plants that take as much as four to eight years to reach commercial operations.  Some of the steepest hurdles faced by developers aren’t in the desert hills but on Capitol Hill.

In “What Would Jefferson Do?,” a 2011 DBL Investors report, Nancy Pfund and Ben Healey wrote (PDF) that average annual support for the oil and gas industry has been $4.86 billion from 1918 to 2009, compared to $3.5 billion for nuclear from 1947 to 1999 and $0.37 billion for renewable energy between 1994 and 2009.

Still, innovation is happening on the Hill to some degree, and geothermal developers have made enormous strides with the incentives they have had for about six years.  Geothermal projects completed since the passing of the 2005 Energy Policy Act include: new flash power plants; re-developed flash power plants; expansion of hybrid geo power plant; new solar/geothermal hybrid plant; binary (ORC) power plants; distributed power generation with building heating system; and co-produced power from oil/gas wells.

As the geothermal industry follows its trajectory of evolution, and if federal support continues for indigenous, reliable energy sources, this list is bound to grow in the coming years.

Swedia Tidak akan Mengindahkan Panggilan Industri untuk Target Tinggi Energi Angin


Ditulis oleh:Torsten Fagerholm, Bloomberg
22 November 2012 | Posting Komentar Anda




Helsinki, Sweeden - Swedia tidak akan merespon panggilan dari angin daya pengembang untuk meningkatkan target untuk output energi alternatif, karena takut merusak kepercayaan investor.

"Saya tahu itu tidak selalu mudah untuk menjadi seorang pengusaha angin-listrik, dengan harga listrik yang rendah sertifikat memicu panggilan untuk intervensi politik," Anna-Karin Hatt, Menteri Swedia untuk teknologi informasi dan energi, mengatakan hari ini di sebuah konferensi di Stockholm, menurut untuk salinan e-mail dari pidatonya.

Angin Swedish Energy Association menginginkan pemerintah untuk menaikkan target untuk investasi energi terbarukan untuk mengamankan pendapatan yang lebih tinggi untuk angin-produsen listrik, pendapatan yang dipengaruhi oleh harga tenang untuk daya dan subsidi listrik diperdagangkan sertifikat. Yang dapat menyebabkan negara itu jatuh pendek resmi tujuan energi terbarukan, kata asosiasi pada 23 Oktober.

"Saya benar-benar khawatir bahwa perubahan tidak direncanakan dan ruam tersebut akan merusak kredibilitas sistem," kata Hatt, mengesampingkan target lebih ketat yang akan mengamankan kelangsungan hidup yang lebih baik untuk pertanian angin.

Sebuah direktif Uni Eropa dari 2009 mengharuskan semua negara anggota untuk meningkatkan proporsi produksi energi terbarukan dalam konsumsi energi bruto dan bersifat final sehingga blok tersebut mencapai total 20 persen pada tahun 2020. Target untuk Swedia adalah 49 persen, dibandingkan dengan pangsa 39,8 persen di tahun 2005.

Sertifikat energi terbarukan yang dapat diperdagangkan, sistem subsidi diperkenalkan di Swedia pada tahun 2003 dan di Norwegia tahun ini, dirancang untuk menambah total 26,4 terawatt-jam output daya tahunan di kedua negara 2012-2020, sebagian besar dari tenaga angin, menurut Swedia Energi Agency.

Pemulihan Depan

Harga rata-rata untuk sertifikat listrik terbarukan selama tahun lalu telah 198,7 kroner ($ 29,4) per megawatt-jam, menurut data di website jaringan Operator Svenska Kraftnaet itu.

Kontrak listrik Nordic untuk 2013 diperdagangkan pada 36,90 € ($ 47,16) megawatt-jam jam 11:47 pagi pada pertukaran energi Nasdaq OMX Group Inc 's di Oslo.

Listrik sertifikat, yang diperdagangkan secara bilateral, telah meningkat "secara nyata sejak musim panas, dan memiliki upside lebih lanjut yang signifikan", kekuatan perdagangan Swedia perusahaan Telge Kraft AB mengatakan hari ini dalam sebuah laporan e-mail. Itu membantu angin-listrik investor untuk menarik pembiayaan, dengan total 100 miliar kronor Swedia ($ 14800000000) atau 3 persen dari Swedia PDB dibutuhkan untuk periode 2012 sampai 2020 untuk meningkatkan produksi tahunan sebanyak 20 terawatt-jam, perusahaan kata.

Sweden Won't Heed Industry Call for Higher Wind Energy Targets


By Torsten Fagerholm, Bloomberg
22 November 2012   |   Post Your Comment




Helsinki, Sweeden -- Sweden will not respond to calls from wind-power developers to boost targets for alternative energy output, for fear of undermining investor confidence.

“I know it is not always easy to be a wind-power entrepreneur, with low electricity certificate prices triggering calls for political intervention,” Anna-Karin Hatt, Swedish minister for information technology and energy, said today at a conference in Stockholm, according to an e-mailed copy of her speech.

The Swedish Wind Energy Association wants the government to raise targets for renewable energy investments to secure higher revenue for wind-power producers, the earnings of which are affected by subdued prices for power and tradable electricity certificate subsidies. That may cause the country to fall short of official renewable energy goals, the association said on Oct. 23.

“I’m genuinely concerned that such unplanned and rash changes would undermine the credibility of the system,” Hatt said, ruling out more stringent targets which would secure better viability for wind farms.

An EU directive from 2009 requires all member-states to increase the proportion of renewable energy production in gross final energy consumption so that the bloc reaches a total of 20 percent by 2020. The target for Sweden is 49 percent, compared with a 39.8 percent share in 2005.

Tradable renewable energy certificates, a subsidy system introduced in Sweden in 2003 and in Norway this year, are designed to add a total of 26.4 terawatt-hours of annual power output in the two countries from 2012 to 2020, mostly from wind power, according to Sweden’s Energy Agency.

Recovery Ahead

The average price for renewable electricity certificates over the past year has been 198.7 kroner ($29.4) per megawatt- hour, according to data on grid operator Svenska Kraftnaet’s website.

The Nordic power contract for 2013 traded at 36.90 euros ($47.16) a megawatt-hour at 11:47 a.m. on the Nasdaq OMX Group Inc.’s energy exchange in Oslo.

Electricity certificates, which are traded bilaterally, have risen “markedly since the summer, and have a significant further upside”, Swedish power trading company Telge Kraft AB said today in an e-mailed report. That’s helping wind-power investors to attract financing, with a total of 100 billion Swedish kronor ($14.8 billion) or 3 percent of Swedish GDP needed for the period 2012 through 2020 to boost annual output to as much as 20 terawatt-hours, the company said.

(Terima kasih khusus pergi keluar untuk pengikut Twitter kami untuk saran besar mereka!)

Tentu saja, ini bukan daftar lengkap, jadi jika Anda memiliki organisasi favorit merasa bebas untuk meninggalkan catatan di komentar di bawah ini.

DIRI

Solar Washington, DC-based Electric Light Fund (SELF) telah menyelesaikan proyek-proyek energi surya di lebih dari 20 negara sejak didirikan pada tahun 1990. Misinya adalah untuk memberikan solusi surya bagi mereka yang hidup dalam kemiskinan energi. DIRI menggunakan Desa Whole nya Model Pembangunan untuk membangun pengembangan masyarakat dan keberlanjutan melalui:

Pendidikan: lampu powering, komputer dan layanan internet nirkabel.
Kesehatan: powering lampu fasilitas, laboratorium, peralatan diagnostik dan lemari es vaksin.
Air & Pertanian: powering sumur air dan pompa untuk air minum yang bersih dan sepanjang tahun irigasi tanaman.
Enterprise: powering pusat untuk usaha kecil dan menyediakan listrik untuk mesin dan peralatan.
Komunitas: rumah electrifying, pusat komunitas, dan penerangan jalan.
Dengan proyek baru-baru ini di Haiti yang menyediakan daya untuk delapan fasilitas medis, ratusan lampu jalan, kekuatan untuk 20 sekolah, sebuah peternakan ikan, dan banyak lagi (sering bekerja bersama Clinton Bush Haiti Fund), DIRI berfokus pada daerah sangat membutuhkan bantuan.

Practical Action

Aksi praktis menempatkan penekanan pada teknologi yang memungkinkan masyarakat pedesaan untuk meningkatkan cara hidup mereka. Dalam kata-katanya sendiri, Practical Action "tahu apa yang orang lakukan dan membantu mereka untuk melakukannya dengan lebih baik." Fokus utama Practical Action adalah dalam peningkatan solusi energi di seluruh dunia.

Dari run-of-sungai mikro-hidro proyek bahwa kekuasaan desa di Zimbabwe untuk proyek skala kecil angin untuk irigasi dan listrik di Peru, Practical Action berusaha untuk merangsang ekonomi dan memperbaiki kondisi hidup secara global.

PA juga merupakan mitra utama dari Energi Berkelanjutan untuk Semua inisiatif, yang berusaha untuk menyediakan energi untuk sub-Sahara masyarakat. Musim gugur ini di International Solar Power, RenewableEnergyWorld.com berbicara dengan beberapa Energi Berkelanjutan untuk Semua organisasi tentang inisiatif. Video di sini.

Sebuah organisasi non-pemerintah internasional (LSM), Practical Action bergantung pada sumbangan dan hibah, dan menurut website-nya tahun lalu 88 pence dalam setiap 1 £ disumbangkan dialokasikan langsung pada operasi, yang sentuh (help?) Lebih dari 1 juta orang .

10:10

Awalnya diluncurkan sebagai proyek Inggris pada 2009, 10:10 telah diperluas untuk lebih dari 25 negara di seluruh dunia. Premis yang sederhana: mengurangi emisi karbon sebesar 10 persen dalam satu tahun. 10:10 pendukung percaya bahwa tujuan ini jauh lebih nyata dan bermanfaat daripada target jangka panjang, seperti yang 50 atau 80 persen pada tahun 2050.

10:10 didasarkan pada sepuluh istilah:

10:10 adalah emisi sukarela pengurangan kampanye untuk setiap organisasi, orang atau bisnis untuk berkomitmen memotong 10% dari emisi mereka dalam jangka waktu 12 bulan.
10:10 adalah kampanye inklusif. Setiap orang, bisnis dan organisasi dipersilahkan untuk bergabung.
Mengimbangi atau perdagangan emisi bisa dalam keadaan tidak bagian dari 10:10, karena tujuannya adalah untuk mengurangi emisi secara langsung.
Keberhasilan dirayakan, bukan kegagalan disorot, sehingga tidak mencegah orang / organisasi dari sign-up karena takut mereka akan dikritik karena gagal untuk mencapai 10%.
Setiap orang yang mendaftar harus secara aktif didorong untuk menyebarkan berita.
Emisi tabungan harus sedapat mungkin dikunci dalam untuk jangka panjang.
Semua organisasi kampanye bebas untuk menjalankan dengan 10:10 jika mereka memilih.
10:10 tidak boleh digunakan sebagai kendaraan untuk pencatutan pribadi atau organisasi.
10:10 adalah kampanye pengurangan segera emisi gas rumah kaca dan tidak boleh digunakan untuk mendorong setiap moral lainnya, agenda sosial atau politik.
Tidak ada organisasi 10:10, yaitu hub negara, harus bersikap dengan cara apapun yang bisa berdampak negatif pada reputasi 10:10 's.
Lebih dari 100.000 orang, 4.000 bisnis, 2.000 sekolah, dan 2.500 organisasi telah mendaftar untuk inisiatif, dan website 10:10 memiliki beberapa studi kasus bahwa strategi garis untuk melaksanakan penyebabnya.

WindAid

WindAid adalah kampanye internasional yang berfokus pada masyarakat dengan akses terbatas atau tidak ada ke jaringan nasional. Sejak memasang turbin secara signifikan lebih murah daripada jalur transmisi memperluas, WindAid berfokus pada off-grid masyarakat di sekitar firman dan bukan hanya menginstall sumber energi, tetapi mendidik masyarakat tentang sumber daya sehingga dapat mandiri, juga.

Sebuah organisasi relawan berbasis, peserta WindAid bekerja dengan insinyur untuk membangun turbin angin dari awal di situs, yang biasanya merupakan proses tiga minggu. Setiap turbin 2,5 kW-biaya sekitar $ 15.000, dana yang berasal dari biaya sukarela (biaya biasanya menjalankan $ 1.950 per orang untuk misi lima-minggu).

Setelah konstruksi dan pengujian selesai, kelompok bergerak ke situs pra-dipilih untuk instalasi. Situs dicalonkan baik dari masyarakat itu sendiri atau seseorang yang bekerja sama dengan masyarakat. Pejabat WindAid menilai setiap masyarakat didasarkan pada apakah mereka telah mendirikan koperasi, diterapkan untuk hibah, bekerja dengan organisasi-organisasi untuk mencapai manfaat untuk masyarakat, dll Jika masyarakat sesuai dengan persyaratan yang diperlukan dan lokasi yang memiliki sumber daya angin yang baik, WindAid ada untuk membantu .

SolarAid

Sementara banyak sudah tahu minyak tanah berbahan bakar cahaya adalah suatu bentuk energi kotor, juga merupakan beban besar bagi mereka yang menggunakannya, dan bisa makan sampai 20 persen dari penghasilan rumah tangga setiap bulan, rata-rata. Dalam miskin negara, ini bentuk energi hanya tidak masuk akal.

SolarAid telah mengakui masalah ini dan telah menetapkan tujuan untuk memberantas lampu minyak tanah dari Afrika pada tahun 2020. Di daerah pedesaan sub-Sahara Afrika, hanya 14,2 persen dari populasi memiliki akses listrik. SolarAid telah menemukan bahwa akses ke matahari pendapatan cahaya meningkat dengan rata-rata 20 persen per bulan, meningkatkan pendidikan dan mempromosikan gaya hidup sehat.

Dengan bantuan donasi, SolarAid menjual pencahayaan surya untuk keluarga (Bagi Light), sekolah (LighterLeaning) dan organisasi di seluruh Afrika dan mendidik masyarakat tentang pentingnya energi bersih. Melalui dana SolarAid, Anda dapat membantu salah satu kekuatan dari 110 juta rumah tangga tanpa listrik di Afrika.

Renewable Energy World Celebrates Global Non-Profits that Advance Sustainability

By Meg Cichon, Associate Editor, RenewableEnergyWorld.com
22 November 2012   | 


In the spirit of giving thanks, we highlight the following renewable energy organizations worldwide. By supporting them, you can help people in need and help renewable energy grow.



New Hampshire, USA -- Whether you welcome it with enthusiasm or pretend it's not happening, the holiday season is upon us. This year, all of us here at RenewableEnergyWorld would like to highlight organizations that uphold the spirit of giving, charity and work for the greater good. Below you will find some of the many organizations with goals to promote and establish renewable energy worldwide.

(A special thanks goes out to our Twitter followers for their great suggestions!)

Of course, this is not a complete list, so if you have a favorite organization feel free to leave a note in the comments below.

SELF

The Washington, D.C.-based Solar Electric Light Fund (SELF) has completed solar energy projects in more than 20 countries since its inception in 1990. Its mission is to provide solar solutions to those living in energy poverty.  SELF uses its Whole Village Development Model to establish community development and sustainability through:

Education: powering lights, computers and wireless internet services.
Health: powering facility lights, labs, diagnostic equipment and vaccine refrigerators.
Water & Agriculture: powering water wells and pumps for clean drinking water and year-round crop irrigation.
Enterprise: powering centers for small businesses and providing electricity for machinery and equipment.
Community: electrifying homes, community centers and street lighting.
With recent projects in Haiti that provide power for eight medical facilities, hundreds of street lights, power to 20 schools, a fish farm, and more (often working alongside the Clinton Bush Haiti Fund), SELF focuses on areas in dire need of assistance.

Practical Action

Practical Action puts an emphasis on technology to enable rural communities to improve their way of life. In its own words, Practical Action “finds out what people are doing and helps them to do it better.”  Practical Action’s major focus is in the improvement of energy solutions worldwide.

From run-of-river micro-hydro projects that power villages in Zimbabwe to small-scale wind projects for irrigation and power in Peru, Practical Action strives to stimulate economies and improve living conditions globally.

PA is also a major partner of the Sustainable Energy for All initiative, which strives to provide energy to sub-Saharan communities. This fall at Solar Power International, RenewableEnergyWorld.com spoke with some of the Sustainable Energy for All organizations about the initiative.  The video is here.

An international non-governmental organization (NGO), Practical Action relies on donations and grants, and according to its website last year 88 pence in every £1 donated was allocated directly to its operations, which touch (help?) more than 1 million people.

10:10

Originally launched as a UK project in 2009, 10:10 has expanded to more than 25 countries around the world. Its premise is simple: reduce carbon emissions by 10 percent in one year. 10:10 supporters believe this goal is much more tangible and beneficial than long-term targets, such as those that are 50 or 80 percent by 2050.

10:10 is based on ten terms:

10:10 is a voluntary emissions reduction campaign for any person, organization or business to commit to cutting 10% of their emissions in a 12 month period.
10:10 is an inclusive campaign. Every person, business and organization is welcome to join.
Offsetting or emissions trading can in no circumstances be part of 10:10, as the aim is to reduce emissions directly.
Successes are celebrated, rather than failures highlighted, so as not to discourage people/organizations from signing-up for fear they will be criticized for failing to achieve 10%.
Everyone who signs up should be actively encouraged to spread the word.
Emissions savings should wherever possible be locked in for the long term.
All campaigning organizations are free to run with 10:10 if they choose.
10:10 must not be used as a vehicle for personal or organizational profiteering.
10:10 is a campaign for immediate reductions of greenhouse gas emissions and should not be used to push any other moral, social or political agenda.
No 10:10 organization, i.e. country hub, should behave in any way that could impact negatively on 10:10’s reputation.
More than 100,000 individuals, 4,000 businesses, 2,000 schools, and 2,500 organizations have signed up for the initiative, and the 10:10 website has several case studies that outline strategies to implement the cause.

WindAid

WindAid is an international campaign that focuses on communities with limited or no access to the national grid. Since installing a turbine is significantly cheaper than extending transmission lines, WindAid focuses on off-grid communities around the word and not only installs an energy resource, but educates the community about the resource so that it can be self-sustaining, as well.

A volunteer-based organization, WindAid participants work with engineers to build wind turbines from scratch on site, which is usually a three-week process. Each 2.5-kW turbine costs approximately $15,000, funds for which come from volunteer fees (costs typically run $1,950 per person for the five-week mission).

Once construction and testing are complete, the group moves to a pre-selected site for installation. Sites are nominated from either the community itself or someone working closely with the community. WindAid officials assess each community based on whether they have established cooperatives, applied for grants, worked with any organizations to achieve for community benefit, etc.  If the community fits the necessary requirements and its location has a good wind resource, WindAid is there to help.

SolarAid

While many already know kerosene-fueled light is a dirty form of energy, it is also a major expense for those that use it, and can eat up to 20 percent of a household’s income each month, on average. In poverty-stricken countries, this form of energy simply doesn’t make sense.

SolarAid has recognized this issue and has set a goal to eradicate kerosene lamps from Africa by 2020. In rural sub-saharan Africa, only 14.2 percent of the population has access to electricity. SolarAid has found that access to solar light increases income by an average of 20 percent per month, improves education and promotes a healthier lifestyle.

With the help of donations, SolarAid sells solar lighting to families (Share a Light), schools (LighterLeaning) and organizations throughout Africa and educates communities about the importance of clean energy. Through the SolarAid fund, you can help power one of the 110 million households without electricity in Africa.

Asia Report: lain Pekan Celakalah bagi Produsen Surya China Panel


Oleh Oliver Wagg, Kontributor
19 November 2012 |



SYDNEY - pembuat terkepung China panel surya terpukul pekan ini, mengumumkan penurunan peringkat pengiriman baik atau PHK dalam menanggapi kelebihan pasokan global dan biaya produksi yang lebih tinggi terkait dengan tarif impor baru-baru ini diberlakukan oleh pemerintah AS.

Trina Solar, yang telah melaporkan kerugian berturut-turut untuk empat kuartal terakhir, memangkas kuartal ketiga bimbingan mengutip seluruh industri kelebihan pasokan dan harga yang lebih rendah. Pembuat panel surya Cina sekarang memperkirakan pengiriman pada kuartal ketiga akan berada di kisaran 375 MW MW ke 385, turun dari bimbingan sebelumnya dari 450 MW menjadi 480 MW, sebagai margin diperas oleh anti-dumping di AS dan inventarisasi menulis -down.

Trina mengatakan pada September bahwa itu memotong jumlah yang tidak diungkapkan dari pekerjaan sebagai bagian dari tindakan untuk menghemat biaya yang lebih luas. Minggu ini giliran Suntech mengumumkan PHK, mengatakan akan mengurangi produksi untuk tiga shift satu dan memotong tenaga kerja di perusahaan Goodyear, Arizona solar panel fasilitas manufaktur.

Produsen terbesar di dunia dari panel surya mengatakan meningkatnya biaya sel surya meningkatkan biaya manufaktur panel surya di Tarif AS pada sel surya datang selain tarif yang diberlakukan oleh pemerintah AS tahun lalu pada frame aluminium, input lain kunci untuk panel surya manufaktur.

"Setelah keputusan kami untuk berinvestasi di Arizona, tidak perlu hambatan perdagangan hulu telah membuat sulit dan lebih mahal untuk memproduksi panel surya di AS Selain itu, tarif baru ini membatasi kemampuan kita untuk memanfaatkan sel canggih Suntech teknologi surya yang diimpor dari China," kata mick McDaniel, managing director Suntech America.

Travis Hoium menulis di Motley Fool: "Ini sekarang harus jelas bahwa perusahaan surya Cina tidak lagi layak sebagai bisnis mereka sedang dibangun. Tidak hanya margin sangat rendah sehingga akan sulit untuk membuat keuntungan, mereka semua memiliki utang yang membuat mereka kurang kompetitif dibandingkan pemasok sehat. "

Hoium telah negatif pada saham surya Cina untuk beberapa waktu, tetapi umumnya telah membuat pendapatnya sangat negatif terbatas pada mereka dengan utang begitu banyak sehingga tidak mungkin mereka pernah bisa bersaing, seperti LDK, Suntech dan Yingli.

Tapi dari laporan pendapatan Kanada Solar, ditambah dengan bimbingan Trina diperbarui mengarah Hoium untuk percaya "bahwa seluruh industri surya China pada akhirnya akan bangkrut, atau ditebus dalam beberapa bentuk."

BERITA DI ATAS

Sinovel untuk menempatkan 351 pekerja cuti di tengah kemerosotan penjualan turbin: Sinovel China, terbesar di dunia-turbin angin penanda berdasarkan nilai pasar, mengatakan, pihaknya akan menempatkan 351 pekerja - 12 persen dari total tenaga kerja perusahaan - cuti dari 19 November karena suatu kemerosotan industri-lebar dalam penjualan.

China mengeluarkan dana untuk proyek-proyek surya: China akan menerima aplikasi baru dari pemerintah daerah untuk subsidi proyek surya untuk mendukung industri fotovoltaik dalam negeri. Proyek-proyek tertentu, yang termasuk ke program Golden Sun, akan menerima subsidi dari 5,5 yuan ($ 0,88) per watt dan harus selesai pada akhir Juni 2013, menurut sebuah pernyataan di website Departemen Keuangan.

Mongolia untuk meningkatkan pengembangan energi terbarukan: Mongolia berencana untuk meningkatkan jumlah energi yang dihasilkan dari sumber yang terbarukan, negara Presiden Tsakhia Elbegdorj mengatakan Senin. Negara ini mengharapkan untuk menghasilkan 20 persen menjadi 25 persen listriknya dari angin, matahari dan sumber daya terbarukan lainnya pada 2020, Elbegdorj mengatakan pada Forum Energi Asia Resources Northeast Kerjasama Terbarukan.

Conergy Jerman menang tawaran untuk membangun peternakan angin dua di Thailand: Conergy Jerman telah memenangkan kontrak untuk memasok suku dan membangun dua peternakan surya di Thailand dengan kapasitas gabungan sebesar 21 MW. Thailand Solar Energy memilih Conergy untuk jasa rekayasa, pengadaan dan konstruksi di taman surya di Suphan Buri dan provinsi Kanchanaburi.

Australia membawa akhir dini untuk skema subsidi solar atap: pemerintah federal Australia telah mengumumkan penutupan awal skema atap surya subsidi. Penutupan skema, enam bulan awal, adalah kedua kalinya pemerintah telah melakukan intervensi dalam program, yang pada awalnya ditujukan untuk berakhir pada tahun 2015.

Infigen, Suntech skala kembali rencana untuk pertanian surya Australia: Australia Infigen Energi dan China Suntech memotong ukuran tanaman surya diusulkan untuk negara Australia New South Wales dengan sekitar seperempat dari rencana semula karena mereka bersaing untuk dana federal. Kedua perusahaan ingin mengembangkan sebuah proyek 35 MW solar-setelah gagal dalam upaya untuk mendapatkan hibah pemerintah untuk rencana 150-MW.

Pengiriman jepang surya dalam negeri naik 80 persen: pengiriman domestik Jepang sel surya dan modul naik 80 persen tahun-ke-tahun dalam tiga bulan hingga September setelah pemerintah memulai program insentif untuk energi bersih di bulan pertama periode. Pengiriman domestik meningkat menjadi 627 MW dari 348 MW pada kuartal yang sama tahun lalu, Photovoltaic Japan Energy Association mengatakan.

Sebuah LOOK LEBIH DALAM

Menjelajahi cleantech Australia pubertas Blues: CleanTech Australia John O'Brien menulis Australia memiliki semua karakteristik dari suatu negara yang harus memimpin dunia cleantech: Penelitian kemampuan yang sangat baik, pasar keuangan yang matang, luar biasa sumber daya energi terbarukan, pasokan air tidak menentu dan emisi yang sangat tinggi per kapita. Ada tentu kemajuan selama tahun 2012 dengan dimulainya program penetapan harga karbon dan hibah, memperkuat fondasi yang dimulai dengan target 20 persen energi terbarukan. Tapi dengan semua upaya ini, cleantech di Australia hanya belum mencapai usia remaja nya.

1400000000 $ rencana surya India digagalkan oleh keterlambatan pasokan, debu: Natalie Obiko Pearson dari Bloomberg menulis India mengharapkan setengah dari $ direncanakan 1,4 miliar dari solar pembangkit listrik termal akan tertunda dan beberapa dihapus sebagai kios pasokan AS dan awan debu meredakan radiasi yang diperlukan untuk mendorong generasi. Dari 500 MW dari proyek akan selesai pada bulan Februari dan Mei, hanya sepertiga dari kapasitas yang mungkin siap pada waktunya.

ON THE HORIZON

Kepailitan mengundang untuk setengah dari tingkat 3 pemasok polysilicon: The prospek suram untuk industri polysilicon global telah diletakkan telanjang oleh prediksi bahwa separuh dari tingkat dunia 3 pemasok polysilicon menghadapi kebangkrutan di bulan depan. Kepala analis PV di iSuppli IHS Henning Wicht kepada majalah pv bahwa sementara produsen polysilicon terbesar di dunia - OCI, Wacker, GCL Poly dan HSC - dapat terus memperluas produksi dengan memperhitungkan kerugian terkait terhadap jangka panjang keuntungan dari pangsa pasar diperluas, pemain yang lebih kecil tidak memiliki kemewahan seperti itu.

Asia Report: Another Week of Woe for China's Solar Panel Manufacturers


By Oliver Wagg, Contributor
19 November 2012   | 



SYDNEY -- China's beleaguered solar panel makers took another hit this week, announcing either shipment downgrades or job cuts in response to global oversupply and higher production costs tied to recent import tariffs imposed by the U.S. government.

Trina Solar, which has reported a loss for the last consecutive four quarters, slashed third-quarter guidance citing industry-wide oversupply and lower prices. The Chinese solar panel maker now estimates shipments in the third quarter would be in the 375 MW to 385 MW range, down from previous guidance of 450 MW to 480 MW, as margins were squeezed by anti-dumping duties in the U.S. and an inventory write-down.

Trina said in September that it was cutting an undisclosed number of jobs as part of a broader cost-saving measure. This week it was Suntech’s turn to announce job cuts, saying it will reduce three production shifts to one and cut the workforce at its Goodyear, Ariz. solar panel manufacturing facility.

The world's largest producer of solar panels said the rising costs of solar cells increases the cost of manufacturing solar panels in the U.S. Tariffs on solar cells come in addition to tariffs imposed by the U.S. government last year on aluminum frames, another key input for solar panel manufacturing.

"Subsequent to our decision to invest in Arizona, unnecessary upstream trade barriers have made it difficult and more costly to manufacture solar panels in the U.S. In addition, these new tariffs limit our ability to utilize Suntech's advanced solar cell technology imported from China," said Mick McDaniel, managing director of Suntech America.

Travis Hoium writes in the Motley Fool: “It should now be clear that Chinese solar companies are no longer viable businesses as they're currently constructed. Not only are margins so low that it would be tough to make a profit, they all have debt that makes them less competitive than healthier suppliers.”

Hoium has been negative on Chinese solar stocks for some time, but generally has kept his strongly negative opinions limited to those with so much debt that it's unlikely they could ever compete, such as LDK, Suntech and Yingli.

But an earnings report from Canadian Solar, coupled with Trina’s updated guidance leads Hoium to believe "that China's entire solar industry will eventually be bankrupt, or bailed out in some form.”

IN THE NEWS

Sinovel to put 351 workers on leave amid slump in turbine sales: China’s Sinovel, the world’s biggest wind-turbine marker by market value, said it plans to put 351 workers — 12 percent of the company’s total workforce — on leave from 19 November because of an industry-wide slump in sales.

China releases funding for solar projects: China will accept new applications from regional governments for solar project subsidies to support the domestic photovoltaic industry. The certain projects, which belong to the Golden Sun program, will receive a subsidy of 5.5 yuan ($0.88) per watt and must be completed by the end of June 2013, according to a statement on the Ministry of Finance website.

Mongolia to increase renewable energy development: Mongolia plans to increase the amount of energy produced from renewable sources, the country’s President Tsakhia Elbegdorj said Monday. The country expects to produce 20 percent to 25 percent of its electricity from wind, solar and other renewable resources by 2020, Elbegdorj said at the Northeast Asia Renewable Energy Resources Cooperation Forum.

Germany’s Conergy wins bid to build two wind farms in Thailand: Germany's Conergy has won a contract to supply parts and build two solar farms in Thailand with a combined capacity of 21 MW. Thai Solar Energy chose Conergy for engineering, procurement and construction services at its solar parks in Suphan Buri and Kanchanaburi provinces.

Australia brings early end to rooftop solar subsidy scheme: Australia’s federal government has announced the early closure of its rooftop solar subsidy scheme. The closure of the scheme, six months early, is the second time the government has intervened in the program, which was originally intended to end in 2015.

Infigen, Suntech scale back plan for Australian solar farm: Australia’s Infigen Energy and China’s Suntech cut the size of a solar plant proposed for Australia’s New South Wales state to about a quarter of the original plan as they vie for federal funds. The two companies want to develop a 35-MW solar project after failing in an attempt to get a government grant for a 150-MW plan.

Japan domestic solar shipments up 80 percent: Japan's domestic shipments of solar cells and modules rose 80 percent year-on-year in the three months to September after the government started an incentive program for clean energy in the first month of the period. Domestic shipments increased to 627 MW from 348 MW in the same quarter last year, the Japan Photovoltaic Energy Association said.

A DEEPER LOOK

Navigating Australia’s cleantech puberty blues: Australian CleanTech’s John O’Brien writes Australia has all the characteristics of a country that should be leading the cleantech world: excellent research capability; mature financial markets; exceptional renewable energy resources; erratic water supplies and very high emissions per capita. There has certainly been progress over 2012 with the start of carbon-pricing and grant programs, strengthening the foundations that were started with the 20 percent renewable energy target. But with all this effort, cleantech in Australia has only yet reached its teenage years.

India’s $1.4 billion solar plan thwarted by supply delays, dust: Natalie Obiko Pearson of Bloomberg writes India expects half of a planned $1.4 billion of solar thermal power stations will be delayed and some scrapped as U.S. supplies stall and dust clouds diffuse the radiation required to drive generation. Of the 500 MW of projects due to be completed in February and May, only a third of that capacity may be ready on time.

ON THE HORIZON

Bankruptcy beckons for half of tier 3 polysilicon suppliers: The bleak outlook for the global polysilicon industry has been laid bare by the prediction that half of the world's tier 3 polysilicon suppliers face bankruptcy in the months ahead. Principal PV analyst at IHS iSuppli Henning Wicht told pv magazine that while the world's biggest polysilicon producers — OCI, Wacker, GCL Poly and HSC — may continue to expand production by offsetting any associated losses against longer-term gains of expanded market share, smaller players had no such luxury.

QUOTE OF THE WEEK

“The Thai government wants to meet one quarter of the country’s energy requirements using renewable energy sources by the year 2022. This is providing a baseline of support to the development of a solar energy market in Thailand.” — Alexander Lenz, President Asia & Middle East for Conergy

Phoenix Rising: Energi Terbarukan Berita Baik Datang ke Cahaya Setelah Badai Sandy


Oleh Jennifer Runyon, Managing Editor, RenewableEnergyWorld.com
20 November 2012 |
Enam potongan berita yang kami telah melihat bahwa kecerdikan showcase energi terbarukan.



Nashua, NH - Sebagai bagian dilanda Sandy Amerika Utara tiga pekan lalu, ratusan aset pembangkit listrik terancam. Menurut SNL Energi, terdapat 731 pembangkit listrik 10 MW dari operasi atau lebih besar di jalur badai. Di antara fasilitas yang 20 PLTN, 80 batu bara pembangkit, 237 berbahan bakar gas tanaman dan 394 tanaman dari berbagai jenis bahan bakar lainnya, termasuk tenaga air, surya, biomassa dan pembangkit tenaga angin.

Meskipun Sandy meninggalkan banyak pelanggan dalam gelap, sebagian besar listrik padam disebabkan oleh distribusi dan kerusakan saluran transmisi daripada kerusakan aset pembangkit yang sebenarnya. Yang mengatakan, setidaknya tiga pembangkit listrik tenaga nuklir yang menggenjot produksinya ke "waspada terhadap kelebihan grid" kata SNL, yang juga melaporkan bahwa satu pabrik nuklir, Exelon Oyster Creek di New Jersey, menyatakan peristiwa darurat selama badai, karena banjir dari tanaman yang beredar sistem air. Acara darurat adalah yang ketiga paling parah pada matriks acara NRC.

Sebagai korban menyaring melalui puing-puing dan yang bekerja paling terpukul untuk mengembalikan beberapa kemiripan kehidupan mereka sebelum badai, kita semua diingatkan tentang kekuatan alam ibu dan kemampuannya untuk menghancurkan umat manusia apa yang telah menghabiskan beberapa dekade bangunan. Kerusakan luas yang dihasilkan dari badai telah meninggalkan banyak orang menyerukan lebih banyak menggunakan bentuk "aman" dari energi dan tindakan yang berarti untuk memerangi perubahan iklim.

Energi terbarukan jawaban kedua panggilan. Mengurangi ketergantungan kita pada bahan bakar fosil CO2 menyemburkan-pembangkit listrik berbahan bakar akan berfungsi untuk mengurangi jumlah polusi yang mengkhawatirkan yang telah pemanasan planet kita sejak Revolusi Industri. Selain itu, aset energi terbarukan yang kuat, aman dan tahan terhadap kerusakan.

Di sini kami menawarkan beberapa tidbits mendorong berita untuk energi terbarukan. Dengan banyak orang masih menderita dari kerusakan yang disebabkan badai, berikut adalah enam ide untuk mendapatkan bersemangat tentang.

Karibia dan Southeastern Wind Turbines Pesisir Fare Nah Selama Sandy

Hanya sekitar satu minggu setelah Badai Sandy, Power Systems Utara mengumumkan bahwa 74 dari turbin angin, termasuk tiga di Karibia, berada di jalur Badai Sandy dan tidak rusak oleh angin kencang. Setelah Irene, badai kategori 3 yang melanda pada tahun 2011, Sandy adalah kuat kedua Atlantik badai menghantam turbin Daya Utara dalam waktu satu tahun dan semua turbin yang terkena dampak dilakukan dengan aman seperti yang diharapkan.

"Kerugian yang dialami akibat Badai Sandy adalah pengingat tragis betapa kuatnya alam bisa," kata Troy Patton, Northern Power Systems Presiden dan CEO. "Banyak dari turbin kami, dari Karibia ke pesisir timur AS, berada langsung di jalur Badai Sandy, tapi tidak ada yang rusak akibat angin kencang. Pada Power Systems Utara, kami memiliki pengalaman dan komitmen untuk terus membuat produk yang aman dan dapat diandalkan. "

Sebagai bukti desain turbin Daya Northern, sesegera turbin masing-masing terdeteksi Sandy badai kekuatan angin, maka secara otomatis masuk ke mode aman. Setelah kondisi kembali normal, turbin masing-masing mulai menghasilkan listrik lagi, kata perusahaan.

Tata Surya Punggung Up Generator, Menjaga Power On di Wajah of Fury Sandy

Ketika Sandy menabrak Bayonne, NJ, sistem satu-of-a-kind listrik surya yang dikembangkan oleh Produk Surya Advanced Flemington, NJ membantu menjaga daya pada di Sekolah Komunitas Midtown, di mana 50 sampai 75 warga kota ini Riverfront Hudson bersejarah menghabiskan malam tidur di ranjang bayi di kamar, masyarakat hangat kering dan remang.

Listrik dari grid hilang untuk semua Bayonne, termasuk Komunitas Sekolah Midtown (kiri), yang juga berfungsi sebagai pusat evakuasi darurat masyarakat, di sekitar 9:00 pada malam 29 Oktober. Lampu di sekolah tinggal di Namun, karena sistem cadangan. Sistem komersial surya skala besar, pada paruh waktu dari proyek tenaga solar terbesar di pantai timur, dirancang dan dibangun dengan bantuan dari Produk Advanced Surya (ASP) dan diinstal pada tahun 2004.

(Gambar, 272 kW array di Midtown, foto courtesy Powerlight Corp)

272-kW PV array yang dirancang untuk beroperasi dalam hubungannya dengan uninterruptible power supply. Satu di sekolah adalah generator diesel menurut Lyle Rawlings yang telah menjabat sebagai presiden sejak 1991 ASP. Generator cukup besar untuk memenuhi kebutuhan listrik sekolah selama kegagalan daya, tetapi menggunakan sejumlah besar bahan bakar diesel, yang harus disampaikan oleh truk jika pasokan dapat ditemukan sama sekali selama dan setelah keadaan darurat seperti Sandy.

"Tanpa tata surya kita di atap sekolah, kita akan membutuhkan bahan bakar lebih, yang akan menjadi sulit untuk menemukan karena itu diperlukan untuk semua truk perbaikan beroperasi di seluruh negara," kata Rawlings.

Dalam rangka memberikan kemampuan ini, sistem tenaga surya sekolah secara khusus dimodifikasi dengan kontrol baru, sensor dan perangkat lunak inovatif yang memungkinkan untuk secara otomatis mendeteksi pemadaman listrik. Ketika hal itu terjadi, segera menggeser produksinya dari sirkuit powering pemanasan biasa sekolah, pendinginan dan pencahayaan sistem untuk sirkuit darurat gedung. "Badai seperti Sandy akan menjadi lebih sering jika kita tidak menghentikan perubahan gas rumah kaca iklim diinduksi," kata Rawlings. "Adopsi luas dari tenaga surya merupakan cara yang ekonomis menguntungkan untuk mengurangi gas rumah kaca dari pembakaran bahan bakar fosil."


Sandy tidak menyakiti Terdistribusi Turbin Angin

Sebagai batas waktu untuk memperpanjang alat tenun energi angin pajak, Wind Energy Association Terdistribusi (DWEA) dan advokat angin energi lainnya yang menggarisbawahi pentingnya tenaga angin sebagai sumber energi yang berkelanjutan untuk usaha kecil dan pemilik rumah.

Atas dan ke bawah pantai, anggota DWEA telah berbagi rekening sistem angin terdistribusi menantang badai di semua negara yang terkena dampak. Cerita termasuk sedikit atau tidak ada kerusakan pada turbin angin anggota 'dari North Carolina ke New York, dan seterusnya.

Mike Bergey, Presiden Bergey Windpower Co, memiliki turbin kW lima 10 dipasang di Nags Head, North Carolina, termasuk tiga turbin di Pier Jennette ini (kiri), yang secara langsung dipengaruhi oleh Sandy. Bergey senang melaporkan bahwa semua lima dari turbin nya selamat badai tanpa cedera.

Menurut Bob Olivio di Villas, New Jersey, "Saya di Teluk Delaware sekitar empat kilometer dari Cape May Aku ada di sini selama badai angin dengan seluruh setinggi 71 mph. Aku tidak pernah didukung Skystream liburku,. Dan saya senang melaporkan bahwa itu masih menghasilkan listrik hari ini. "

Berdasarkan data kecepatan angin dari Pusat Topan Nasional, turbin yang direkayasa untuk menahan angin 120 mph akan mudah lapuk Sandy ¹ murka s tetapi banyak bisnis dan pemilik rumah tidak menganggap energi angin sebagai sumber energi alternatif sampai terlambat.

"Kami berharap bahwa warga dan pemilik bisnis akan mempertimbangkan kekuatan energi angin sebagai sumber teruji dan berharga energi untuk menghasilkan listrik. Ketika semuanya gagal, energi angin memiliki kemampuan untuk cuaca badai dan menjaga lampu menyala," kata Jennifer Jenkins, direktur eksekutif, DWEA.


Sandy Meningkatkan Minat Pemanasan Panas Bumi dan Pendinginan





Menurut sebuah artikel di NY Times, Badai Sandy membantu untuk menunjukkan pemilik Kota New bangunan lebih York nilai sistem panas bumi untuk pemanasan dan pendinginan. Poin artikel ke banyak digali setengah kosong tangki bahan bakar yang muncul di daerah banjir di daerah paling terpukul oleh badai. Sistem panas bumi, yang menggunakan 40 konstan - atau 50-derajat suhu bumi sebagai bahan bakarnya - sebagai lawan minyak - yang lebih aman dan lebih ramah lingkungan dibandingkan bahan bakar fosil rekan-rekan mereka. (Lihat diagram tentang bagaimana sistem bekerja, di atas.)

Reardon, manajer pengeboran panas bumi untuk Long Island berbasis Kelompok Lingkungan Miller dikutip dalam artikel NY Times mengatakan bahwa sejak badai ia telah tangkas panggilan lebih dari pemilik bangunan tertarik pada sistem panas bumi daripada sebelumnya. Sejak Badai Sandy hancur pemanasan begitu banyak dan sistem pendinginan, berharap mendengar lebih banyak tentang panas bumi di New York di tahun mendatang. Menurut artikel itu, sistem yang lebih panas bumi yang sudah dipasang di New York, New Jersey dan Pennsylvania daripada di tempat lain di Amerika Serikat.


Puing Sandy Digunakan untuk Listrik Biomassa di Connecticut

The Hartford Business Journal menunjukkan dalam sebuah artikel yang Holdings ReEnergy, perusahaan New York yang mengoperasikan fasilitas biomassa Sterling (bawah) di Sterling, Connecticut telah menggunakan Badai puing-puing Sandy untuk daya pabrik. Fasilitas, yang sampai listrik padam Connecticut dari 2011 telah menggunakan ban bekas sebagai sumber bahan bakar utamanya, diversifikasi dalam rangka untuk menerima lebih dari 100.000 meter kubik puing-puing yang terakumulasi setelah badai es.

Karena fasilitas kini telah sepenuhnya dikonversi untuk menerima puing-puing badai bersama dengan palet, kayu bersih dan residu hutan, ia mengumpulkan puing-puing dari Badai Sandy.

Jika prediksi itu benar dan kita harus mengharapkan badai lebih intensitas yang lebih besar akan maju kemudian bersih-up akan tetap masalah. Fasilitas seperti ini akan menjadi semakin penting dalam mencari tahu bagaimana mengelola semua reruntuhan bahwa badai besar seperti Sandy akan menciptakan.



Pertanian angin Kuba Menderita Tidak ada Kerusakan Dari Sandy

Badai Sandy menghancurkan ribuan rumah di bagian timur Kuba, terutama di sekitar Santiago de Cuba, kota kedua terbesar di negara itu. Daerah yang terkena, provinsi Holguín, juga terjadi menjadi rumah bagi dua peternakan angin: Gibara I, 5.1-MW pembangkit listrik yang terdiri dari enam 850-kW turbin yang terpasang pada tahun 2008, dan Gibara II: pembangkit 4,5 MW- yang terdiri dari enam 750 kW-mesin yang dipasang pada tahun 2010 (lihat gambar).

Kedua peternakan angin sepenuhnya dilanda badai Sandy, yang membawa kecepatan angin hingga 110 mil per jam. Setelah pemeriksaan awal, pemerintah Kuba mengumumkan pada pertemuan dengan Asosiasi Energi Angin Dunia (WWEA) di Havana yang tak satu pun dari dua peternakan angin mengalami kerusakan besar dari oleh badai dan bahwa mereka masih menyediakan listrik untuk jaringan lokal.

Stefan Gsänger, WWEA Sekretaris Jenderal mengatakan bahwa badai adalah pengingat yang baik dari kerentanan peradaban kita terhadap bencana alam. Dia mengatakan bahwa sejak peternakan angin selamat tsunami 2010 di Jepang dan badai 2012 di Kuba, "kita harus belajar pelajaran kita dari ini dan mempercepat secepat mungkin pergeseran ke arah energi terbarukan yang terdesentralisasi seperti tenaga angin, di seluruh dunia."

Phoenix Rising: Renewable Energy Good News Comes to Light After Hurricane Sandy


By Jennifer Runyon, Managing Editor, RenewableEnergyWorld.com
20 November 2012   | 
Six pieces of news we've seen that showcase renewable energy ingenuity.



Nashua, NH -- As Sandy ravaged parts of North America three weeks ago, hundreds of power generation assets were threatened. According to SNL Energy, there were 731 operating power plants of 10 MW or larger in the path of the storm. Among these facilities were 20 nuclear plants, 80 coal-fired plants, 237 gas-fired plants and 394 plants of various other fuel types, including hydropower, solar, biomass and wind power plants.

Even though Sandy left many customers in the dark, most of the power outages were caused by distribution and transmission line damage rather than damage to actual generating assets.  That said, at least three nuclear power plants were ramped down to “guard against grid overload” said SNL, which also reported that one nuclear plant, Exelon's Oyster Creek in New Jersey, declared an emergency event during the storm, due to flooding of the plant's circulating water system.  The emergency event was the third most severe on the NRC event matrix.

As survivors sift through the wreckage and those hardest hit work to restore some semblance of the life they had before the storm, we are all reminded of the power of mother nature and its ability to destroy what mankind has spent decades building. The widespread damage that resulted from the storm has left many people calling for more use of “safer” forms of energy and meaningful action to combat climate change.

Renewable energy answers both calls.  Lessening our dependence on CO2 spouting fossil fuel-fired power plants will serve to reduce the alarming amount of pollution that has been warming our planet since the Industrial Revolution.  In addition, renewable energy assets are strong, safe and resistant to damage.

Here we offer a few tidbits of encouraging news for renewable energy.  With many people still suffering from the damages the storm caused, here are a six ideas to get excited about.

Caribbean and Southeastern Coastal Wind Turbines Fare Well During Sandy

Just about a week after Hurricane Sandy, Northern Power Systems announced that 74 of its wind turbines, including three in the Caribbean, had been in the path of Hurricane Sandy and were undamaged by the high winds. Following Irene, a category 3 hurricane that hit in 2011, Sandy was the second powerful Atlantic storm to hit Northern Power turbines within a year and all turbines that were impacted performed safely as expected.

“The losses experienced from Hurricane Sandy are a tragic reminder of how powerful nature can be,” said Troy Patton, Northern Power Systems President and CEO. “Many of our turbines, from the Caribbean to the eastern seaboard of the U.S., were directly in the path of Hurricane Sandy, but none were damaged by the high winds. At Northern Power Systems, we have the experience and commitment to continue to make products that are safe and reliable.”

As a testament to the design of Northern Power’s turbines, as soon as each turbine detected Sandy’s hurricane force winds, it automatically entered safe mode. Once conditions returned to normal, each turbine started generating electricity again, said the company.

Solar System Backs Up Generator, Keeps Power On in Face of Sandy’s Fury

When Sandy slammed into Bayonne, NJ, a one-of-a-kind solar electric system developed by Advanced Solar Products of Flemington, NJ helped keep the power on at Midtown Community School, where 50 to 75 residents of this historic Hudson Riverfront city spent the night sleeping on cots in the warm, dry and well-lit community room.

Power from the grid was lost to all of Bayonne, including Midtown Community School (left), which also serves as a community emergency evacuation center, at about 9:00 on the evening of October 29. The lights at the school stayed on, however, because of its backup system. The large commercial-scale solar system, at the time part of the largest solar power project on the east coast, was designed and built with assistance from Advanced Solar Products (ASP) and installed in 2004.

The 272-kW PV array was designed to operate in conjunction with an uninterruptible power supply. The one at the school is a diesel generator according to Lyle Rawlings who has served as president of ASP since 1991. The generator is large enough to meet the electricity needs of the school during a power failure, but uses huge quantities of diesel fuel, which must be delivered by truck if supplies can be located at all during and after an emergency such as Sandy.

“Without our solar system on the roof of the school, we would have needed even more fuel, which would have been difficult to find because it was needed for all the repair trucks operating around the state,” said Rawlings.

In order to provide this capability, the school's solar power system was specially modified with new controls, sensors and innovative software to enable it to automatically detect a power outage.  When it does, it immediately shifts its output from circuitry powering the school’s ordinary heating, cooling and lighting systems to the building's emergency circuits. “Storms such as Sandy will become more frequent if we do not stem greenhouse gas induced climate change,” says Rawlings.  “Widespread adoption of solar power is an economically beneficial way to reduce greenhouse gases from burning fossil fuels.”


Sandy Didn’t Hurt Distributed Wind Turbines

As the deadline to extend the wind energy tax looms, the Distributed Wind Energy Association (DWEA) and other wind energy advocates are underscoring the importance wind power as a sustainable source of energy for small business and home owners.

Up and down the coast, DWEA members have shared accounts of distributed wind systems braving the storm in all impacted states.  Stories include little to no damage to members' wind turbines from North Carolina to New York, and beyond.

Mike Bergey, President of Bergey Windpower Co., had five 10 kW turbines installed in Nags Head, North Carolina, including three turbines on Jennette's Pier (left), which was directly impacted by Sandy.  Bergey was pleased to report that all five of his turbines survived the storm unscathed.

According to Bob Olivio in Villas, New Jersey, "I am on the Delaware Bay approximately four miles from Cape May. I was here during the entire storm with winds as high as 71 mph.  I never powered my Skystream off, and am pleased to report that it's still generating electricity today."

Based on wind speed data from the National Hurricane Center, turbines that are engineered to withstand 120 mph winds would have easily weathered Sandy¹s wrath but many business and home owners don't consider wind energy as an alternative energy source until it's too late.

"We hope that citizens and business owners will consider the power of wind energy as a tested and valuable source of energy to generate electricity.  When all else fails, wind energy has the ability to weather the storm and keep the lights on," said Jennifer Jenkins, executive director, DWEA.


Sandy Raises Interest in Geothermal Heating and Cooling





According to an article in the NY Times, Hurricane Sandy is helping to show more New York City building owners the value of geothermal systems for heating and cooling. The article points to the many unearthed half-empty fuel tanks that popped up in flooded areas across regions hardest hit by the storm.  Geothermal systems, which use the constant 40- or 50-degree temperature of the earth as their fuel – as opposed to oil – are safer and more environmentally friendly than their fossil-fuel counterparts. (See a diagram of how the systems work, above.)

David E. Reardon, manager of geothermal drilling for Long Island-based Miller Environmental Group is quoted in the NY Times article saying that since the storm he has been fielding more calls from building owners interested in geothermal systems than ever before. Since Hurricane Sandy destroyed so many heating and cooling systems, expect to hear more about geothermal in New York in the coming year.  According to the article, more geothermal systems are already installed in New York, New Jersey and Pennsylvania than anywhere else in the United States.


Sandy Debris Used for Biomass Power in Connecticut

The Hartford Business Journal points out in an article that ReEnergy Holdings, the New York company that operates the Sterling biomass facility (below) in Sterling, Connecticut has been using Hurricane Sandy debris to power its plant. The facility, which up until the Connecticut power outages of 2011 had used discarded tires as its main fuel source, diversified in order to accept the more than 100,000 cubic yards of debris that accumulated after that ice storm.

Since the facility has now been fully converted to accept storm debris along with pallets, clean wood and forest residues, it is collecting debris from Hurricane Sandy.

If the predictions are true and we should expect more storms of greater intensity going forward then clean-up will remain an issue.  Facilities like this one will become increasingly important in figuring out how to manage all of the wreckage that major storms like Sandy will create.



Cuban Wind Farms Suffered No Damage From Sandy

Hurricane Sandy destroyed thousands of houses in the Eastern part of Cuba, mainly around Santiago de Cuba, the country's second largest city. The affected area, the province of Holguín, also happens to be home to two wind farms: Gibara I, a 5.1-MW power plant consisting of six 850-kW turbines that were installed in 2008; and Gibara II: a 4.5-MW plant that consists of six 750-kW machines that were installed in 2010 (see image).

Both wind farms were fully hit by hurricane Sandy, which brought wind speeds of up to 110 miles per hour. After initial inspections, the Cuban government announced at a meeting with the World Wind Energy Association (WWEA) in Havana that neither one of the two wind farms suffered any major damage from by the hurricane and that they still provide electricity for the local grid.

Stefan Gsänger, WWEA Secretary General said that the hurricane was a good reminder of the vulnerability of our civilization to natural disasters.  He said that since wind farms survived the 2010 tsunami in Japan and the 2012 hurricane in Cuba, “we should learn our lessons from this and accelerate as fast as possible the shift towards decentralized renewable energy such as wind power, all over the world."

Geothermal Inovasi, Bagian 2: Waduk Stimulating di Bidang Kemitraan dan di Industri


Oleh Leslie Blodgett, GEA
21 November 2012 | Posting Komentar Anda



WASHINGTON DC - inovasi terbaru The industri AS panas bumi yang berkontribusi terhadap potensi meningkatnya penggunaan panas bumi untuk listrik masa depan energi terbarukan, namun resiko dimuka tinggi dan biaya pembangunan adalah salah satu alasan kebutuhan panas bumi program pendanaan federal untuk memperluas.

"Insentif federal dan negara membantu menarik investor untuk proyek-proyek panas bumi, dan sangat penting untuk mengatasi hambatan yang dihadapi industri saat ini. Namun, dengan pertumbuhan yang berkelanjutan dan inovasi, biaya dan risiko proyek harus menurun sebagai industri mengembang dan meningkatkan teknologi, "menurut Asosiasi Geothermal Energy (GEA) Direktur Eksekutif Karl Gawell.

Tahun 2005 Undang-Undang Kebijakan Energi disediakan baru pembangkit listrik tenaga panas bumi insentif pajak yang sama sebagai proyek angin: US $ 0,02 per kilowatt hour dihasilkan selama masing-masing dari sepuluh tahun pertama produksi.

Terkenal di dunia panas bumi adalah laporan dari Massachusetts Institute of Technology (MIT) yang dilakukan pada tahun 2006, yang bisa dibilang membantu mengantar fokus pada penelitian untuk EGS. "Masa Depan Energi Panas Bumi, Dampak Sistem Panas Bumi Ditingkatkan untuk Abad 21" menyatakan bahwa EGS bisa memberikan Amerika Serikat dengan sekitar 100 gigawatt-setara kapasitas domestik dalam 50 tahun ke depan.

Juga dicatat adalah sebuah lokakarya 2010 tentang "Eksplorasi dan Penilaian Sumber Daya Panas Bumi" di mana Pusat Great Basin untuk Geothermal Energy (GBCGE), Teknologi DOE Kantor Program Panas Bumi (DOE-GTP) dan GEA mengundang profesional panas bumi untuk membahas negara pengetahuan eksplorasi sumber daya panas bumi. Diskusi berkisar teknik eksplorasi di bidang Geologi dan Struktur, Geofisika, Remote Sensing, Geokimia, Distribusi Suhu, dan Karakterisasi Reservoir.

Pemahaman geologi sangat penting untuk proses pembangunan. Dalam Bagian 1 dari tampilan dua bagian pada teknologi panas bumi, Energi Panas Bumi Association (GEA) meneliti beberapa teknik dan alat-alat yang memfasilitasi kemajuan dalam pengujian geologi dan analisis untuk proyek-proyek panas bumi konvensional dan EGS.

Terhadap latar belakang ini, GEA bertanya bagaimana DOE didanai proyek panas bumi yang dilakukan dalam Q & A dengan Lead Tim Panas Bumi Departemen Teknologi Program untuk hidrotermal & Sumber Daya Konfirmasi Hildigunnur Thorsteinsson:

GEA: Dari sudut pandang DOE, apa kemajuan telah dibuat dalam EGS sejak Laporan MIT dan mengapa EGS bagian besar dari portofolio dalam memajukan teknologi panas bumi?

DOE: "Pada Departemen, kita melihat energi panas bumi, sepanjang jalan dari sumber hidrotermal konvensional untuk EGS, sebagai bagian penting dari strategi energi semua-of-the-atas yang mengembangkan setiap sumber yang tersedia energi Amerika.

"Sementara EGS memiliki potensi besar untuk memberikan, besar, bersih, beban-dasar, sumber energi ini juga dapat membantu memfasilitasi pengembangan panas bumi di luar daerah hidrotermal tradisional di Amerika Serikat bagian barat dengan memperluas produksi energi panas bumi untuk area tambahan di negara ini.

"Membangun off temuan dari studi MIT, kami telah bekerja dengan mitra industri dan universitas untuk meningkatkan pemahaman kita tentang bawah permukaan melalui pemodelan canggih dan metode simulasi.

"Energi Departemen Penelitian di aman, stimulasi efisien dan metode pemantauan telah membantu memajukan sejumlah proyek percontohan EGS. Misalnya, melalui sebuah proyek yang didanai DOE demonstrasi EGS, Calpine mampu berhasil membuat waduk EGS baru dengan meningkatkan permeabilitas dan menghubungkan sumur multiple di bagian utara-barat dari Bidang Air Mancur.

"Selain itu, DOE didanai AltaRock EGS demonstrasi dijadwalkan untuk memulai stimulasi pada proyek percontohan inovatif mereka EGS di Oregon."



Proyek-proyek yang menerima GTP dalam program pendanaan mewakili beberapa beberapa inovasi panas bumi paling kreatif terjadi hari ini untuk membantu membawa industri di jalur kompetitif dengan pilihan lain energi alternatif.

Upaya Departemen luas untuk panas bumi adalah untuk menurunkan biaya pengembangan dan mengurangi hambatan teknis dan pasar untuk peningkatan produksi di Amerika Serikat, kata Thorsteinsson GEA.

"Menghapus hambatan-hambatan pada akhirnya akan memperkuat kelayakan ekonomi dari pengembangan panas bumi, dan membantu menyediakan sumber daya, beban-dasar yang bersih terbarukan dan dapat diandalkan untuk rumah Amerika dan bisnis," kata Thorsteinsson.

GEA: Bagaimana saat GTP proyek membantu untuk mengurangi biaya untuk industri pada umumnya?

DOE: "Program Teknologi Panas Bumi mendukung berbagai proyek yang bertujuan bijaksana, aman dan biaya-efektif pengembangan sumber daya panas bumi di Amerika Serikat. Sebagai contoh, kami telah mendukung penelitian tentang kelangsungan hidup menggunakan lubang inti berdiameter kecil daripada penuh-diameter sumur sebagai lubang eksplorasi. Penelitian ini sekarang membayar dividen yang signifikan dalam industri, membantu eksplorasi lebih rendah dan biaya pengeboran untuk pengembang panas bumi AS.

"Hari ini, Departemen berinvestasi dalam teknologi menjanjikan beberapa untuk membantu mengurangi biaya," tambahnya. "Sebagai contoh, kami mendukung proyek R & D pada teknologi pengeboran perkusi yang memiliki potensi untuk secara signifikan meningkatkan tingkat penetrasi di sumur. Teknologi ini telah digunakan dengan sukses besar di bidang pertambangan dan tim proyek mencari cara untuk beradaptasi teknologi untuk lingkungan downhole dari sumur panas bumi. "

Lubang inti berdiameter kecil dan teknologi pengeboran perkusi hanya dua bidang penelitian lebih lanjut sedang dilakukan oleh DOE mitra.

Thorsteinsson memuji karya Faulds James dari University of Nevada-Reno. "Pada pertemuan Dewan Sumber Daya Panas Bumi baru-baru ini di Reno, kantor kami diakui [Faulds] dengan tahun 2012 rekan Penghargaan Ulasan Excellence untuk pekerjaan besar timnya dalam menggambarkan kontrol struktural Sistem Panas Bumi Ditingkatkan (EGS) dan reservoir panas bumi konvensional.

"Kami berharap dapat bekerja sama dengan industri kami, laboratorium nasional dan mitra universitas untuk melanjutkan penelitian ini penting dan proyek percontohan," katanya.

Faulds adalah setengah jalan bekerja pada "Karakterisasi Kontrol Struktural EGS dan Reservoir Panas Bumi konvensional," yang memenangkan penghargaan $ 1.000.000 DOE untuk mengkarakterisasi potensi panas bumi di hampir 500 lokasi di seluruh Great Basin "Kami ingin membantu industri mencapai tingkat yang dapat diterima dari situs. -seleksi risiko menjelang pengeboran mahal, "Faulds dikutip di situs berita universitas.

Thorsteinsson mengatakan, "The University of Nevada-Reno tim melakukan penelitian penting untuk membantu mencirikan kontrol struktural EGS dan waduk hidrotermal konvensional, memperkuat kemampuan pemodelan kami dan membantu mengidentifikasi sumber daya baru dengan biaya lebih rendah.

"Selama tahun lalu, tim ini telah mendefinisikan sebuah array pengaturan struktural yang menguntungkan untuk sistem panas bumi dan telah menyelesaikan sebuah katalog awal pengaturan struktural untuk sistem Great Basin," tambah Thorsteinsson. "Sebagai proyek terus, kami berharap dapat melanjutkan pemahaman kita tentang kontrol struktural dan model untuk berbagai kegiatan panas bumi."

Pelaporan pada 2010 eksplorasi dan lokakarya penilaian, GBCGE, GTP dan GEA menemukan banyak pekerjaan yang diperlukan pada model struktural rinci di Great Basin dan seterusnya, seperti Cascades, Rio Grande Rift, Sungai Ular, dan Imperial Valley. Kesalahan kontrol patah tulang dan permeabilitas merupakan fitur kunci yang perlu dipahami terutama, mereka menemukan.

"Apa Jim Faulds membawa ke meja adalah pemahaman besar struktur geologi dan gaya struktural dalam sistem panas bumi, membantu untuk mengidentifikasi, misalnya, zona ketegangan dan permeabilitas terkait antara helai kesalahan," kata Ann Robertson-Tait dalam percakapan terakhir dengan GEA. Robertson-Tait adalah seorang ahli geologi dan Manajer Pengembangan Bisnis untuk GeothermEx, sebuah konsultan lama berdiri panas bumi yang sekarang merupakan bagian dari Schlumberger, ladang minyak perusahaan jasa global.


Thorsteinsson (DOE Geothermal Technologies Program) alamat peserta pada National Summit Geothermal GEA itu, Agustus 2012, Robertson-Tait (GeothermEx) adalah yang kedua dari kanan.
Aliran fluida panas bumi di sepanjang kesalahan adalah sebuah konsep yang telah sekitar untuk waktu yang lama, berdasarkan pengamatan umum bahwa sumber air panas yang terletak di sepanjang atau dekat jejak kesalahan. "Idenya adalah bahwa cairan itu naik dari kedalaman besar sampai ke permukaan bersama pesawat kesalahan, tetapi model yang telah cukup baik ditembak jatuh dalam semua tetapi beberapa kasus," kata Robertson-Tait. "Jelas ada hubungan antara kesalahan dan sumber air panas, tapi ini adalah fenomena yang relatif dangkal. Apa yang lebih penting untuk pengembang panas bumi adalah kontrol pada permeabilitas dan aliran fluida di kedalaman. Kontrol ini lebih rumit untuk menyelesaikan, dan sering melibatkan kombinasi dari cakrawala stratigrafi permeabel dan patahan. "

Mengembangkan Jaringan Fraktur di Nevada

Hot Springs Brady di Nevada adalah contoh yang baik. "Mata air panas di bidang ini jelas terjadi sepanjang jejak kesalahan," kata Robertson-Tait. Ormat Nevada Inc, operator proyek panas bumi Brady, adalah penerima dana DOE di bidang ini selama proyek EGS bertujuan untuk meningkatkan permeabilitas dalam satu atau dua sumur marjinal. Dalam perjalanan proyek ini, Ormat telah bekerja dengan Jim Faulds, GeothermEx dan lain-lain untuk menafsirkan geologi. "Karya ini telah mengungkapkan bahwa perpanjangan lokal telah menciptakan serangkaian kesalahan, masing-masing dengan relatif kecil offset, menciptakan zona membentang-out permeabilitas. Karya ini telah mengubah model konseptual dari lapangan Brady, "menurut Robertson-Tait.

DOE telah memberikan hibah $ 3.400.000 untuk bekerja pada pengembangan jaringan fraktur di rumah Brady, yang memiliki lingkungan yang stres dan formasi batuan yang menguntungkan bagi peningkatan permeabilitas. Situs Brady ini terletak dekat proyek Puncak Desert panas bumi Ormat, yang juga menerima DOE-dana untuk perbaikan baik menggunakan teknik EGS.

Sebuah, interaktif real-time peta aktivitas seismik di Desert Peak dan Brady Hot Springs dapat dilihat di Lawrence Berkeley National Laboratory (LBNL) 's Ilmu Bumi situs Web.

Memprediksi Permeabilitas di LBNL

Energi Sumber Daya Program LBNL ini memungkinkan penelitian energi pengembangan panas bumi. Program LBNL terlihat untuk mengurangi ketidakpastian yang berhubungan dengan mencari, karakteristik, dan mengevaluasi sumber daya panas bumi. Program ini bertujuan untuk secara signifikan meningkatkan produksi sumber daya panas bumi melalui pemahaman pengembangan dan peningkatan permeabilitas dan aliran cairan untuk EGS, menurut situs Web-nya.

LBNL ini mengembangkan sistem yang handal untuk membantu memprediksi suhu reservoir melalui DOE-nya didanai "Sistem Geothermometry Kimia Terpadu Eksplorasi Geothermal" proyek. Tujuannya adalah untuk memungkinkan prediksi suhu reservoir panas bumi dengan menggunakan analisis kimia musim semi dan cairan dengan baik.

Para ilmuwan kemudian dapat "memanfaatkan data geokimia dari berbagai lokasi, yang bertujuan untuk memberikan penilaian yang lebih handal dari suhu target reservoir yang lebih geothermometers kimia tradisional," kata Thorsteinsson. "Dengan meningkatkan kemampuan kita untuk menilai suhu reservoir, penelitian ini adalah membantu industri lebih memahami potensi sumber daya dan mengurangi biaya pengembangan proyek."

Robertson-Tait mengatakan bahwa unsur-unsur kimia dan geomekanika kode pemodelan numerik penting, terutama untuk EGS. Sementara kode ini sekarang menjadi tersedia sebagian besar keluar dari Labs Nasional, ada juga kode komersial yang memiliki kemampuan ini. "Banyak dari kode ini menangani isu-isu yang sangat penting dalam EGS, dan saya pikir itu adalah perkembangan yang baik. Dana DOE ke National Labs telah pergi jauh, dan ada kode komersial juga, suasana yang menggabungkan penelitian dan persaingan. "

GEA: Apa inovasi lainnya terlihat menjanjikan?

DOE: "Di proyek kami yang berbeda, Panas Bumi Departemen Teknologi Program membantu untuk melakukan penelitian dan mengembangkan teknologi baru yang mengurangi biaya pengembangan energi panas bumi dan meningkatkan efisiensi operasional. Ini R & D tidak hanya maju teknologi produksi yang lebih hemat biaya dan inovatif yang sedang digunakan di lapangan saat ini, tetapi juga sumber daya karakterisasi canggih dan praktik lingkungan hidup pelindung yang membangun industri yang berkelanjutan selama beberapa dekade yang akan datang.

"Sepanjang pekerjaan ini, kami terus mencari cara baru untuk menurunkan biaya dan meningkatkan operasi. Misalnya, kita melakukan jalan-teknologi pemetaan latihan untuk menentukan jalur teknis yang paling menjanjikan untuk menghasilkan energi panas bumi, termasuk mengembangkan geofisika canggih dan alat-alat geokimia dan memanfaatkan penginderaan jauh. "

Upaya DOE roadmapping harus mempercepat proses perijinan untuk penerima beasiswa potensial, meningkatkan biaya proyek, dan mengurangi resiko investor.

Selain itu, database Biaya baru Transparan DOE berisi ribuan perkiraan dari lebih dari 100 studi yang dipublikasikan dan program-perencanaan atau anggaran DOE dokumen, bagian dari jalan yang sedang berlangsung upaya-pemetaan untuk berbagai teknologi.

GEA: Bagaimana teknologi panas bumi mirip dengan teknologi minyak dan gas, dan bagaimana mereka berbeda? Bagaimana hal ini membantu atau menyakiti industri?

DOE: "Banyak teknologi dan kemajuan alat yang dibuat dalam industri minyak dan gas dapat bermanfaat bagi masyarakat panas bumi, sama, perkembangan teknologi dan penemuan yang dibuat dalam panas bumi sering dapat digunakan dalam minyak dan gas. Bahkan, penelitian awal di Departemen Energi pada pengeboran terarah dan teknologi bor sekarang digunakan baik dalam industri gas panas bumi dan alam.

"Namun, lingkungan panas bumi biasanya memiliki suhu yang lebih tinggi dan rock keras dari minyak tradisional dan memainkan gas, jadi kami bermitra dengan industri untuk mengembangkan teknologi baru yang dapat beroperasi secara efektif dan aman dalam lingkungan yang unik."

Eksplorasi 2010 dan lokakarya penilaian melaporkan bahwa eksplorasi model sistem berada dalam tahap awal pengembangan, di mana pertambangan atau minyak dan gas adalah 50 atau lebih tahun yang lalu.

Pendanaan untuk Teknologi Geothermal: 2006 -?

Perwakilan Kongres mungkin tidak tahu persis perbedaan antara produksi minyak dan produksi panas bumi, tetapi tanggal kadaluarsa menjulang ada pada insentif pajak federal. Sementara geoanalysts melakukan bagian mereka untuk grafik menguraikan dan bacaan, tanggal kadaluwarsa jangka pendek pada diterjemahkan kredit pajak untuk waktu yang buruk untuk tanaman panas bumi yang mengambil sebanyak empat sampai delapan tahun untuk mencapai operasi komersial. Beberapa rintangan curam yang dihadapi oleh pengembang tidak di perbukitan gurun tapi di Capitol Hill.

Dalam "Apa yang Akan Jefferson Do?," Laporan Investor 2.011 DBL, Nancy Pfund dan Ben Healey menulis (PDF) yang mendukung tahunan rata-rata untuk industri minyak dan gas telah 4860000000 $ 1918-2009, dibandingkan dengan $ 3,5 miliar untuk nuklir dari 1947-1999 dan $ 0370000000 untuk energi terbarukan antara tahun 1994 dan 2009.

Namun, inovasi yang terjadi di bukit untuk beberapa derajat, dan pengembang panas bumi telah membuat langkah besar dengan insentif yang mereka miliki selama sekitar enam tahun. Proyek panas bumi selesai sejak berlalunya Kebijakan Energi 2.005 Act meliputi: flash baru pembangkit listrik, kembali mengembangkan Flash pembangkit listrik, perluasan pembangkit listrik geo hybrid; surya baru / panas bumi tanaman hibrida, biner (ORC) pembangkit listrik, pembangkit listrik didistribusikan dengan sistem pemanas bangunan, dan co-diproduksi listrik dari minyak / gas sumur.

Sebagai industri panas bumi mengikuti lintasan evolusi, dan jika dukungan federal berlanjut adat, sumber energi yang dapat diandalkan, daftar ini pasti akan tumbuh di tahun-tahun mendatang.

Geothermal Innovations, Part 2: Stimulating Reservoirs in the Field and Partnerships in the Industry


By Leslie Blodgett, GEA
21 November 2012   |   Post Your Comment



WASHINGTON D.C. -- The U.S. geothermal industry's recent innovations contribute to increasing potential for the use of geothermal to power the renewable energy future, but high upfront risks and costs of development are one reason geothermal needs federal funding programs to expand.

“Federal and state incentives help attract investors to geothermal projects, and are essential to overcoming the obstacles facing the industry today.  But, with continued growth and innovation, the cost and risk of projects should decline as the industry expands and technology improves,” according to Geothermal Energy Association (GEA) Executive Director Karl Gawell.

The 2005 Energy Policy Act provided new geothermal power plants the same tax incentive as wind projects: US$ 0.02 per kilowatt hour produced during each of the first ten years of production.

Well-known in the geothermal world is a report from the Massachusetts Institute of Technology (MIT) conducted in 2006, which arguably helped to usher in a focus on research for EGS.  "The Future of Geothermal Energy, Impact of Enhanced Geothermal Systems for the 21st Century” stated that EGS could provide the United States with about 100 gigawatt-equivalent of domestic capacity in the next 50 years.

Also of note was a 2010 workshop on “Exploration and Assessment of Geothermal Resources” in which The Great Basin Center for Geothermal Energy (GBCGE), the DOE Geothermal Technology Program office (DOE-GTP) and the GEA invited geothermal professionals to discuss the state of knowledge of exploration for geothermal resources.  The discussion revolved around exploration techniques in areas of Geology and Structure, Geophysics, Remote Sensing, Geochemistry, Temperature Distribution, and Reservoir Characterization.

An understanding of geology is essential to the development process.  In Part 1 of this two-part look at geothermal technologies, the Geothermal Energy Association (GEA) examined some of the techniques and tools that are facilitating progress in geological testing and analysis for conventional and EGS geothermal projects.

Against this backdrop, GEA asked how DOE-funded geothermal projects are doing in a Q&A with the Department’s Geothermal Technologies Program’s Team Lead for Hydrothermal & Resource Confirmation Hildigunnur Thorsteinsson:

GEA: From DOE’s standpoint, what advancements have been made in EGS since the MIT Report and why is EGS a big part of the portfolio in advancing geothermal technologies?

DOE: "At the Department, we see geothermal energy, all the way from conventional hydrothermal resources to EGS, as an important part of an all-of-the-above energy strategy that develops every available source of American energy.

"While EGS has great potential to provide a large, clean, baseload, energy resource it can also help facilitate geothermal development outside of traditional hydrothermal areas in the western United States by extending geothermal energy production to additional areas in the country.

"Building off the findings of the MIT study, we have worked with industry and university partners to enhance our understanding of the subsurface through advanced modeling and simulation methods.

"Energy Department research in safe, efficient stimulation and monitoring methods has helped advance a number of EGS demonstration projects. For example, through a DOE funded EGS demonstration project, Calpine was able to successfully create a new EGS reservoir by increasing permeability and connecting multiple wells in the north-west part of The Geysers field.

"In addition, the DOE-funded AltaRock EGS demonstration is scheduled to initiate stimulation at their innovative EGS demonstration project in Oregon."



The projects that GTP accepts in its funding programs represent some of the some of the most creative geothermal innovations happening today to help bring the industry on a competitive track with other alternative energy options.

The Department’s broader efforts for geothermal are to lower its development costs and reduce the technical and market barriers to increased production in the United States, Thorsteinsson told GEA.

“Removing these barriers will ultimately strengthen the economic viability of geothermal development, and help provide a clean, renewable and reliable baseload resource for American homes and businesses,” Thorsteinsson said.

GEA: How will current GTP projects help to mitigate costs for the industry at large?

DOE: “The Geothermal Technologies Program is supporting a variety of projects aimed at prudently, safely and cost-effectively developing geothermal resources in the United States. As an example, we have supported research on the viability of using small-diameter core holes rather than full-diameter wells as exploration holes. This research is now paying significant dividends in the industry, helping to lower exploration and drilling costs for U.S. geothermal developers.

“Today, the Department is investing in several promising technologies to help further reduce costs,” she added. “For example, we are supporting an R&D project on percussive drilling technology that has the potential to significantly increase the rate of penetration in wells. This technology has been used with great success in mining and the project team is looking at ways to adapt the technology to the downhole environment of a geothermal well.”

Small-diameter core holes and percussive drilling technology are just two areas of further research being carried out by DOE partners.

Thorsteinsson hailed the work of James Faulds of the University of Nevada-Reno.  “At the recent Geothermal Resource Council meeting in Reno, our office recognized [Faulds] with the 2012 Peer Review Excellence Award for his team’s great work in characterizing structural controls of Enhanced Geothermal Systems (EGS) and conventional geothermal reservoirs.

“We look forward to working with our industry, national laboratory and university partners to continue these important research and demonstration projects,” she said.

Faulds is halfway through work on "Characterizing Structural Controls of EGS and Conventional Geothermal Reservoirs,” which won a $1 million DOE award to characterize geothermal potential at nearly 500 sites throughout the Great Basin.  “We want to help the industry achieve acceptable levels of site-selection risk ahead of expensive drilling,” Faulds was quoted on the university’s news site.

Thorsteinsson said, “The University of Nevada-Reno team is conducting important research to help characterize structural controls of EGS and conventional hydrothermal reservoirs, strengthening our modeling capabilities and helping identify new resources at a lower cost.

“Over the past year, this team has defined an array of favorable structural settings for geothermal systems and has completed a preliminary catalogue of structural settings for Great Basin systems,” Thorsteinsson added.  “As the project continues, we look forward to furthering our understanding of structural controls and models for a range of geothermal activities.”

Reporting on their 2010 exploration and assessment workshop, GBCGE, GTP and GEA found more work is needed on detailed structural models in the Great Basin and beyond, such as the Cascades, Rio Grande Rift, Snake River, and Imperial Valley.  Fault control of fractures and permeability are key features that need to be particularly understood, they found.

“What Jim Faulds brings to the table is a great understanding of structural geology and structural styles in geothermal systems, helping to identify, for example, zones of tension and associated permeability between fault strands,” said Ann Robertson-Tait in a recent conversation with GEA.  Robertson-Tait is a geologist and the Business Development Manager for GeothermEx, a long-established geothermal consultancy that is now part of Schlumberger, the global oilfield services company.

Geothermal fluid flow along faults is a concept that has been around for a long time, based on the common observation that hot springs are located along or near fault traces.  “The idea was that the fluid was rising from great depths all the way to the surface along a fault plane, but that model has been fairly well shot down in all but a few cases,” Robertson-Tait said.  “There is clearly a relationship between faults and hot springs, but this is a relatively shallow phenomenon.  What’s more important to geothermal developers are the controls on permeability and fluid flow at depth.  These controls are more complicated to resolve, and often involve a combination of permeable stratigraphic horizons and faulting.”

Developing Fracture Networks in Nevada

Brady’s Hot Springs in Nevada is a good example.  “The hot springs in this field are clearly occurring along a fault trace,” Robertson-Tait noted.  Ormat Nevada Inc., the operator of the Brady’s geothermal project, is the recipient of DOE funding at this field for an EGS project aimed at improving permeability in one or two marginal wells.  In the course of this project, Ormat has worked with Jim Faulds, GeothermEx and others to reinterpret the geology.  “This work has revealed that localized extension has created a series of faults, each with relatively small offset, creating a stretched-out zone of permeability.  This work has changed the conceptual model of the Brady’s field,” according to Robertson-Tait.

DOE has provided a $3.4 million grant for work on developing fracture networks at Brady’s, which has a stress environment and rock formations that are favorable for permeability enhancements.  The Brady’s site is located near Ormat’s Desert Peak geothermal project, which has also received DOE-funding for well improvements using EGS techniques.

An interactive, real-time map of seismic activity at Desert Peak and Brady's Hot Springs is viewable on the Lawrence Berkeley National Laboratory (LBNL)’s Earth Sciences Web site.

Predicting Permeability at LBNL

LBNL‘s Energy Resources Program enables geothermal energy development research.  The LBNL program looks to reduce uncertainties associated with finding, characterizing, and evaluating geothermal resources.  The program seeks to significantly increase production of geothermal resources through understanding the development and enhancement of permeability and fluid flow for EGS, according to its Web site. 

The LBNL is developing a reliable system to help predict reservoir temperatures through its DOE-funded “Integrated Chemical Geothermometry System for Geothermal Exploration” project.  The goal is to enable prediction of geothermal reservoir temperatures using chemical analyses of spring and well fluids.

Scientists can then “leverage geochemical data from multiple locations, aimed at providing a more reliable assessment of target reservoir temperature over traditional chemical geothermometers,” Thorsteinsson said.  “By enhancing our ability to assess reservoir temperatures, this research is helping industry better understand resource potential and reduce the costs of project development.”

Robertson-Tait said that the chemical and geomechanical elements of numerical modeling codes are important, especially for EGS.  While the codes are now becoming available largely out of the National Labs, there are also commercial codes that have these capabilities.  “Many of these codes handle issues that are particularly important in EGS, and I think that’s a good development.  DOE funding to the National Labs has gone a long way, and there are commercial codes too, an atmosphere that combines research and competition.”

GEA: What other innovations look promising?

DOE: “Across our different projects, the Department’s Geothermal Technologies Program is helping to conduct research and develop new technologies that reduce the cost of geothermal energy development and improve the efficiency of operations.  This R&D has not only advanced more cost-effective and innovative production technologies that are being used in the field today, but also sophisticated resource characterization and protective environmental practices that are building a sustainable industry for decades to come.

“Throughout this work, we continue to look for new ways to lower costs and improve operations.  For example, we conduct a technology road-mapping exercises to determine the most promising technical pathways for producing geothermal energy, including developing advanced geophysics and geochemistry tools and leveraging remote sensing.”

DOE’s roadmapping efforts should speed the permitting process for potential awardees, improve project costs, and lessen investor risk.

Additionally, the DOE’s new Transparent Cost Database contains thousands of estimates from more than 100 published studies and DOE program-planning or budget documents, part of ongoing road-mapping efforts for various technologies.

GEA: How are geothermal technologies similar to oil and gas technologies, and how are they different?  How does this help or hurt the industry?

DOE: “Many of the technologies and tool advancements made in the oil and gas industry can be beneficial to the geothermal community; equally, technology developments and discoveries made in geothermal can often be used in oil and gas.  In fact, early research at the Department of Energy on directional drilling and drill bit technologies is now used in both the geothermal and natural gas industries.

“However, geothermal environments typically have higher temperatures and harder rock than traditional oil and gas plays, so we are partnering with industry to develop new technologies that can operate effectively and safely in this unique environment.”

The 2010 exploration and assessment workshop reported that exploration system models are in the earliest stages of development, where mining or oil and gas were 50 or more years ago.

Funding for Geothermal Technologies: 2006-?

Congressional representatives may not know the exact differences between producing oil and producing geothermal, but a looming expiration date exists on federal tax incentives.  While geoanalysts do their part to decipher charts and readings, short-term expiration dates on tax credits translates to bad timing for geothermal plants that take as much as four to eight years to reach commercial operations.  Some of the steepest hurdles faced by developers aren’t in the desert hills but on Capitol Hill.

In “What Would Jefferson Do?,” a 2011 DBL Investors report, Nancy Pfund and Ben Healey wrote (PDF) that average annual support for the oil and gas industry has been $4.86 billion from 1918 to 2009, compared to $3.5 billion for nuclear from 1947 to 1999 and $0.37 billion for renewable energy between 1994 and 2009.

Still, innovation is happening on the Hill to some degree, and geothermal developers have made enormous strides with the incentives they have had for about six years.  Geothermal projects completed since the passing of the 2005 Energy Policy Act include: new flash power plants; re-developed flash power plants; expansion of hybrid geo power plant; new solar/geothermal hybrid plant; binary (ORC) power plants; distributed power generation with building heating system; and co-produced power from oil/gas wells.

As the geothermal industry follows its trajectory of evolution, and if federal support continues for indigenous, reliable energy sources, this list is bound to grow in the coming years.
