ESMAP: Report on getting to gender equality in energy infrastruture

Think Geo - Geothermal Energy - Thu, 04/26/2018 - 21:59
Getting to Gender Equality in Electricity Infrastructure: Lessons from Electricity Generation, Transmission, and Distribution Projects sets out to examine the social and gender footprint of large-scale electricity generation, transmission, and distribution projects to establish a foundation on which further research and replication of good practices can be built. The main impact pathways analyzed are access to land and labor markets, along with social sustainability considerations, including health and education. The study adopted this approach because, according to the World Development Report 2012, gender equality in access to land and labor markets matters for women’s agency and empowerment. In addition, the study considers the role of the energy utilities and businesses to better understand the roles of various stakeholders.

The study’s mixed-methods research approach comprises in-country qualitative and quantitative field research, along with extensive literature and portfolio reviews. Qualitative analyses of several projects distinguished by their project type, energy source, and geographical representativeness were conducted to better understand how infrastructure construction can change the lives of local people. The World Bank Group (WBG) portfolio review provides guidance on how to operationalize good practices and lessons learned to move the energy-gender agenda forward. The study’s primary audiences are energy task teams and social and gender specialists of the WBG and other development agencies, along with energy practitioners seeking better ways to address the gender aspects of energy infrastructure projects throughout the project and lending cycles.

Work on classification on geothermal resources on Flores Island

Think Geo - Geothermal Energy - Thu, 04/26/2018 - 21:37

Flores, an Indonesian island named for its beautiful flora, is the test-bed of a newly adapted classification guidelines for geothermal projects. Called the ‘UNFC Geothermal Specifications,’ this United Nations’ adapted resource classification system is for the first time being piloted on the small island with the support of IRENA, the International Geothermal Association (IGA) and the World Bank.

Committed to improving socio-economic conditions through stable and reliable energy access, some countries with the right geothermal resources are pursuing geothermal energy. Challenging this pursuit, however, has been the struggle to attract financing — showing that to succeed a geothermal project needs to be more than just technically possible.

“Tapping into geothermal energy is about more than just steam,” says Abdulmalik Oricha Ali, an IRENA programme officer helping to coordinate the new geothermal assessment pilot schemes. “Geothermal energy can only benefit anyone if it’s economically competitive, and for that investors need both technical and socio-economic assessments,” Ali adds. In Indonesia, the UNFC Geothermal Specifications can be used by authorities to promote clarity to potential investors on geothermal prospects.

The UNFC system holistically encompasses the management of socio-economical, technological and uncertainty aspects of energy and mineral projects. Using the classification system’s project maturity and resource progression model, investors can identify projects to match their preferred risk profile, reduce exposure to potential costly failures and protect their investments.

From 20 to 23 of March, 2018, IRENA and partners from the IGA and World Bank shared with Indonesian government officials and geothermal project investors how the UNFC system can help classify Flores’s numerous geothermal fields — acknowledging the difference between technical feasibility and economic viability.

It is estimated that across Indonesia’s 17,000 islands there could be as much as 29.5 gigawatts (GW) theoretical geothermal potential, and the country has set in motion plans to harness it. In 2017, Indonesia had almost 2 GW of installed geothermal capacity, and during September’s High-Level Conference of the Global Geothermal Alliance, Indonesia’s Ministry of Energy and Mineral Resources outlined how the country intends to become the world’s biggest producer of geothermal energy by 2021.

“By 2025 we plan to have over 7 GW of geothermal capacity,” said Pak Sanusi Satar, Vice Chairman of the Indonesian Geothermal Association, describing his country’s geothermal ambitions. INAGA representatives attended the Flores workshop and were presented with an overview of the initiative’s objectives — joining in group work to classify a subset of Flores’s projects.

“This workshop has been useful to us because in our standards we’ve been focusing on just the technical aspects of geothermal projects, but in the UNFC we include it all — the social, economic, financial, and geological aspects. I find them interesting and useful and hope we can apply classification,” Satar says. The sessions provided hands-on training to empower the Indonesian authorities to continue the work themselves to classify projects in the rest of Indonesia.

“For us this session was very much needed,” says Pak Dikdik Risdianto, a geologist with the Indonesian Geological Agency. “Our work has only looked at exploration without feasibility or economic considerations, but after this UNFC course, we’ve realised we need to look beyond just resources and think about economics.”

Though the initial feedback from the workshop in Indonesia has been overwhelmingly positive, the work for the IRENA team working on the initiative, has just begun. IRENA and its partners plan to continue to pilot the classification system in different countries and across continents to optimise it for different needs globally.

Costa Rica utility awarded on emission savings through geothermal plants

Think Geo - Geothermal Energy - Thu, 04/26/2018 - 21:26

This week, the Chorotega Region of the Generation Business of the Costa Rican Institute of Electricity (ICE) received an acknowledgment from the Directorate of Climate Change of MINAE for the development of the inventory of greenhouse gas ( GHG ) emissions in power generation plants.

The report corresponds to the Las Pailas geothermal power plants , Miravalles Complex I , II, III, V and Boca de Pozo; SolarMiravalles ; Tejona wind farm and the Arenal, Sandillal and Miguel Dengo hydroelectric plants .

These awards are given to organizations that participate with the public-private initiative called Carbon Neutrality Country Program, for the fulfillment of the national goals established in this matter for 2021.

The Chorotega Region of Generation of the ICE recorded in its inventory 250 tons of carbon dioxide equivalent (CO2e) in direct emissions, 36 tons of indirect emissions and 462 tons of emissions generated from biomass , in 2015.

From the total, between 2016 and 2017 it was possible to reduce 230 tons of CO2e, in operation and maintenance activities of power plants, which meant a cost reduction of approximately ? 60 million.

The inventory includes emissions generated by the consumption of hydrocarbons, chemical products, gases, ordinary wastewater, waste management by grid cleaning, emissions of generation inputs (such as non-condensable gases from geothermal energy and reservoirs) and electricity.

“ICE is undoubtedly a fundamental strategic partner in advancing the goal and especially the decarbonisation of the economy. It is a very important reference and an example that even large organizations can make improvements in their internal processes to reduce emissions, “said Andrea Meza, director of Climate Change at MINAE.

In order to comply with this process, ICE applied the methodology indicated in the INTE-ISO 14064-1 standard and sections of the “WBSD / WRI GHG Protocol” to power generation plants, including awareness and training for personnel.

In addition to internal checks carried out by multidisciplinary teams of the Generation Business, external verification was carried out by the Institute of Technical Norms of Costa Rica (INTECO).

“This step taken by the Generation Business is an acknowledgment of the work that has been done in terms of the electricity matrix, which is the most decarbonised in Latin America. It is also an incentive for the other institutional areas to continue working on the path of sustainability, through the determination and management of their own carbon footprint, “said Miguel Víquez, environmental manager of the ICE’s Corporate Electricity Department.

In addition to the record of GHG emissions of 100% of the Chorotega Region , the Generation Business of the Institute has already accounted for 75% of the plants in the Central Region and 100% of Huetar .

Arctic Green Energy completes $150m equity & debt funding

Think Geo - Geothermal Energy - Thu, 04/26/2018 - 21:16

Arctic Green Energy has completed new funding with its long-time partner CITIC Capital (via the CITIC Kazyna Investment Fund) and welcomes China Everbright as a new shareholder. The funding from this round will be used to finance the company‘s growth strategy as well as to refinance existing debt.

  • An early investor since May 2015, CITIC Capital has exercised its conversion rights to acquire direct equity of USD 30 million in Arctic Green Energy;
  • China Everbright Limited has purchased shares and an exchangeable bond issued by Arctic Green Energy for a total of USD 70 million;
  • The above funding is in addition to the recently announced USD 50 million loan facility provided by the Asian Development Bank, which has now been completed.

Arctic Green Energy‘s strategy is to create zero emission cities through renewable resources, technology and infrastructure. Currently, most of its projects are based on geothermal as the primary energy source. Cities consume over 70% of all energy generated globally. A large portion comes from burning fossil fuels for heating and cooling causing fast escalating air pollution and deteriorating public health. Geothermal is a baseload, profitable renewable energy and the best response to air pollution and emissions while providing people with a clean, renewable and less expensive option than coal heating.

Mr Haukur Harðarson, chairman and founder of Arctic Green Energy, will remain the company‘s majority shareholder, with CITIC Capital and China Everbright holding significant minority stakes.

“The completion of this USD 150 million financing round is a significant step for Arctic Green Energy. Firstly, we have elevated our financial strength to support the continued growth of the company. Secondly, we are refinancing existing funding structure at improved terms and thirdly, but most importantly, we are welcoming two new shareholders that bring a significant strategic value to the firm.  CITIC Capital has been an investor in Arctic Green Energy since 2015 and we highly value the relationship and trust built with them during the past three years. Furthermore, we welcome China Everbright to broaden the investor group to strengthen its ties with China, and build on this success in other markets. CITIC Capital and China Everbright are two global investment firms with strong roots in Asia that have special focus on clean energy and will now.

European Geothermal Congress 2019 – 11-14 June 2019 – The Hague, Netherlands

Think Geo - Geothermal Energy - Wed, 04/25/2018 - 23:25

EGEC, in cooperation with Stichting Platform Geothermie, BodemenergieNL, and the main event sponsor Energie Beheer Nederland B.V. (EBN) are pleased to announce that the 2019 edition of the European Geothermal Congress (EGC) will be held on 11-14 June 2019 at the World Forum, The Hague, in The Netherlands.

Organised every 3 years by EGEC, the European association representing the geothermal sector, EGC is the largest geothermal congress in Europe. Hosting a combination of events for all the geothermal sector, EGC is a unique opportunity for stakeholders from all parts of the sector, whether academic, industrial, financial, policy-making, or societal, to come together and to learn, finding new ways to progress.

“We expect that geothermal solutions will cover a significant part of the future heat demand, in households as well as in industrial applications,” said Jan Willem van Hoogstraten, CEO of EBN. “In that perspective, we see it as a privilege to be the main sponsor of the EGC 2019, and to be involved in all geothermal processes.”

Geothermal energy utilisation in The Netherlands has been experiencing a tremendous growth in recent years, mainly due to the development of policy instruments that tackled barriers such as geological uncertainty, high upfront costs, and the difficulty in ensuring adequate financing. Today, The Netherlands is one of the fastest growing European market, especially in the heating sector. There are 16 large heating plants in operation and about 50,000 individual geothermal heating systems.

The hosting city of The Hague, which aims to become carbon-neutral by 2040, is also looking at geothermal energy for their energy needs. In the next 5 years, at least 4 geothermal heating plants are planned to become operational in the city.

Deputy Mayor Joris Wijsmuller, Urban Development and Sustainability, said: “Geothermal heat is key for the city of The Hague: it enables us to reach carbon neutrality in a cost effective way in 2040.  Eventually, we expect to fulfil half of the city’s heat demand with geothermal heat. Since sustainability in general and alternative energy sources in particular are crucial issues in our city, we are delighted to welcome this year’s EGC in The Hague”.

Following its established format, EGC will feature: a conference programme with both oral and poster presentations; contributions from local, national and European political leaders; sessions covering science and research, education, policy, financing, and communication; a large industry exhibition; site visits to geothermal projects; networking events … and much more.

The call for papers will be announced soon. Over four hundred abstracts were submitted in the last edition, and we look forward to an even larger number of high quality submissions for this edition. To keep informed, sign up to the conference mailing list.

Ethiopian government seeking international investors for geothermal development

Think Geo - Geothermal Energy - Wed, 04/25/2018 - 18:10

As reported from Ethipia, the Ethiopian Energy Authority reports that it has been tirelessly working to utilize country’s energy potentials whilst maximizing the involvement of potential local and foreign investors in the sector.

Geothermal Resource Development Director with the Authority Tesfaye Kassa reports that consolidated efforts are underway to lure investors with the desirable capital, technology and expertise in the geothermal development. Investors could maximize their profitability in furthering their engagement in geothermal sector that enable them to produce electricity without interruptions and harm in the environment, the Director recommended.

Tesfaye says that the government has been hugely engaged in diversifying energy resources to lessen the adverse impact of drought and other natural phenomena caused by hydro power generation plants while eyeing geothermal a viable solution.

The establishment of the Energy Authority as new entity also showcased government’s commitment to harness geothermal energy resources in the Second Growth and Transformation Plan period, Tesfaye elaborated. Ethiopia has an immense potential of geothermal energy related to other East African Rift Valley countries, said Tesfaye adding that twenty-four areas are identified as potential geothermal development sites.

According to him, Ethiopia’s geothermal potential areas are classified in to two categories and areas. Areas with resources of less than 120 degrees Celsius in temperature would be meant to recreational and steam purposes. And investors are encouraged to build star-designated hotels and lodges. Areas with resources over 120 degrees Celsius in temperature would be reserved for energy production.

Expressing the Institute’s interest to attract potential investors in both investments, the Director indicated that the private sectors’ involvement has not reached at a desirable level.
Mentioning seven licenses were offered to four companies, Tesfaye indicated that only Langano project commenced operation with an installed capacity of producing 7.2 MW  of electricity while the remaining are conducting feasibility studies.

Capitalizing on the existing viable policy and the commitment government has shown to develop the sector, many foreign companies with huge capital and technological capabilities have shown a growing interest to involve in the geothermal development, the Director noted.

Moving forward on the Fiale geothermal project at Lake Assal, Djibouti

Think Geo - Geothermal Energy - Wed, 04/25/2018 - 06:33

As part of an announcement of services to be delivered to a geothermal project in Djibouti, Africa, we learn more details on the Fiale geothermal project at Lake Assal.

In its release, French company Vallourec, a supplier of premium tubular solutions primarily serving the energy markets, reports on the project.

Lake Assal is a saline lake, 155m below sea level, situated in central-western Djibouti at the top of the Great Rift Valley. The geothermal potential of the area, known for its seismic and volcanic activity, has been studied for many years and now the drilling campaign to capture this energy is under way!

The project in the Fiale Caldera area of Lake Assal consists of drilling 4 exploration wells for a new geothermal power plant, set to come on-line in 2021. The power plant will have a total capacity of 50 MW. The Fiale project is managed by the Project Management Unit under the authority of Electricity of Djibouti, EDD. It is financed by the World Bank, the African Bank for Development, OPIC, French Agency for Development, GEF and ESMAP.

The produced fluid from the wells is expected to be concentrated sea water that has been heated to around 305°C, although the temperatures could be as high as 360°C at the bottom of the well. The wells will be drilled directionally, reaching vertical depth of 2,500 meters.

For the government of Djibouti, geothermal energy represents a low cost, renewable and clean energy source which will generalise access to electricity for the population and promote economic development. On its side, Vallourec is committed to supporting the development of geothermal energy to make this challenge a reality.

Research: How optimising positioning of geothermal wells can reduce seismicity

Think Geo - Geothermal Energy - Tue, 04/24/2018 - 06:54

When constructing geothermal systems for the extraction of heat from underground hot water reservoirs, optimal positioning of the boreholes can considerably reduce seismicity. This is the result of induced seismicity studies by scientists of Karlsruhe Institute of Technology (KIT). Induced seismicity means shocks caused by human activities. Based on the change of water pressure in the rock (pore pressure) and the mechanical stresses in the rock, the researchers modeled changes of the stress field as a result of the injection and extraction of fluids, e.g. gases or liquids. This is reported in the journal ERDÖL ERDGAS KOHLE.

Injection of liquids into the underground e.g. at geothermal facilities, when injecting wastewater, or for the geological storage of carbon dioxide as well as the removal of fluids for e.g. natural gas production may cause noticeable tremors. These earthquakes caused by human activities (induced seismicity) are based on mechanical principles: Both injection and extraction change the pore pressure, i.e. the water pressure , and, hence, the stress state in the rock. As a result, natural fracture surfaces in the underground may be displaced relative to each other, similar to a small natural earthquake.

Based on this poroelastic coupling of pore pressure and stress, Dr. Birgit Müller und Professor Frank Schilling of KIT’s Institute of Applied Geosciences and the State Geothermal Energy Research Center located at KIT have now studied the seismicity induced by injection and extraction. The project was carried out in cooperation with researchers of the German Research Centre for Geosciences (GFZ) in Potsdam and the engineering office Piewak & Partners, Bayreuth. “For disruptions in the underground of variable orientation, such as fracture surfaces, it is possible to calculate whether induced seismicity can be expected to result from geoengineering activities. From this, recommendations can be derived for the positioning of boreholes and production operation in order to reduce the risk of induced seismicity,” Dr. Birgit Müller summarizes the results published in the journal ERDÖL ERDGAS KOHLE.

The findings are of high relevance to hydrothermal systems for the use of deep geothermal energy, which extract heat from the hot water circulating in an underground reservoir. Water is pumped out at one point and, after cooling down, injected into the ground again at another point. “Our modeling results show that the probability and extent of induced seismicity in hydrothermal systems can be reduced significantly by an active pore pressure management in the reservoir as well as by optimal positioning of the boreholes relative to the orientation of tectonic stresses,” Dr. Birgit Müller says.

U.S. DOE announces $14.5m funding on research on efficient drilling for geothermal

Think Geo - Geothermal Energy - Tue, 04/24/2018 - 06:38

Today, the U.S. Department of Energy (DOE) announced up to $14.5 million in new funding to advance geothermal energy development. The Efficient Drilling for Geothermal Energy (EDGE) funding opportunity announcement (FOA) will focus on geothermal drilling in support of accelerating the research and development of innovative geothermal energy technologies in America.

“Advancing research in geothermal drilling technologies will help harness the heat beneath our feet to expand our domestic energy resources,” said Daniel Simmons, Principal Deputy Assistant Secretary for Energy Efficiency and Renewable Energy. “Geothermal is a reliable, baseload renewable energy source with firm and flexible operation, allowing it to provide a range of essential services that contribute to our nation’s grid stability and resiliency.”

Geothermal energy represents a clean, efficient, and nearly inexhaustible domestic energy resource. The U.S. currently has an installed geothermal capacity of more than 3.8 gigawatts (GW), and there is an estimated 100 GW or more of additional potential geothermal development accessible in undiscovered hydrothermal and enhanced geothermal systems. Technological innovation is necessary to economically convert these resources into cost-effective energy services. DOE’s Geothermal Technologies Office (GTO) supports early-stage research and development (R&D) to achieve these necessary technological breakthroughs.

The EDGE FOA aims to continue and expand GTO’s R&D in geothermal drilling by covering three topic areas:

  • Topic Area 1 focuses on early-stage R&D projects to reduce common delays in drilling operations like lost circulation, stuck pipe, unstable wellbores, and other issues that take time away from deepening the hole, typically referred to as non-drilling time.
  • Topic Area 2 focuses on early-stage R&D projects in innovative drilling technologies that improve the rates of penetration for drilling geothermal wells.
  • Topic Area 3 focuses on exploring innovative approaches and models to accelerate the transfer of geothermal drilling and related technologies from the laboratory into the real world by focusing on building partnerships that will increase adoption of nascent technology and improving knowledge transfer in the geothermal industry.

The application process will include two phases: a Concept Paper phase and a Full Application phase. Applicants must first submit a Concept Paper by 5 PM ET on May 31, 2018 to be eligible to submit a Full Application.

ElectraTherm successful brings another geothermal generator online in Japan

Think Geo - Geothermal Energy - Tue, 04/24/2018 - 06:29

In a release today, Reno, Nevada based ElectraTherm, announces the commissioning of a Power+ Generator® at a geothermal site in the northern part of Japan. The geothermal heat forms an onsen (hot spring) where the local community has enjoyed bathing at this natural resource for centuries. The Power+ installation offers another resource to the community. The generator runs off a low temperature geothermal resource and the baseload renewable power generated is sold to the local utility at an attractive feed-in-tariff rate. The installation also reduces the cost of cooling the onsen water that is otherwise too hot for bathing. This marks the second Power+ Generator in Japan utilizing geothermal heat to generate fuel-free, emission-free electricity.

ElectraTherm utilizes the Organic Rankine Cycle (ORC) and proprietary technologies to generate up to 65kWe of electricity at the site. The Power+ Generator captures low temperature heat ranging from 77°C to 116?C and flow rates up to 45.4 m3/hr. Unlike other renewable sources, geothermal heat is baseload, providing a continuous flow of hot water and therefore power generation capabilities 24/7. The geothermal resource captures hot water —  the fuel used by the Power+ to drive the ORC cycle and turning ElectraTherm’s twin screw power block, driving an electric generator to make clean electricity.

ElectraTherm’s Power+ Generators utilize waste heat on applications such as internal combustion engines, biomass boilers, incinerators, geothermal and also flare to power methane utilization at wastewater treatment plants and oil & gas fields. ElectraTherm’s Power+ fleet of 60+ global installations has exceeded 815,000 hours of run time. A list of reference sites is currently available on the company’s website.

Developer successfully drills 6,400m well for geothermal heating project in Finland

Think Geo - Geothermal Energy - Tue, 04/24/2018 - 01:55

In a statement on LinkedIn, the CEO of St1 Oy Finland and St1 Norge AS Norway announces that the first well in the Otaniemi project has now been drilled to the final depth of 6,4 km this past weekend. With the well, the company has shown the world that deep wells can be drilled into Scandinavian granite in cooperation with St1 and partners.

The company’s goal is to build industrial scale heat plant running on geothermal energy. To date, three deeper wells have been drilled for research use; in Russia 12.3 km, in Germany 9.1 km and in Sweden 6.96 km. The drilled now is the deepest well ever drilled for energy production, a world record in its kind.

The goal of St1 Deep Heat is to build Finland’s first industrial scale heat plant running on geothermal energy. Energy company Fortum will act as a partner and buy the energy for Espoo’s district heating network.

St1 already has experience on sustainably produced energy, and geothermal heat is a natural next step. The process where geothermal heat is extracted is fairly simple. Process begins when two 7-km-deep holes are drilled into the crust of the Earth. Water is fed down to the bedrock where its temperature will rise due to geothermal heat. The hot water will rise up, and the heat will be entered into district heating network. A complete plant should produce as much as 40 megawatts of energy.

The challenge of the project is Finland’s hard bedrock and a specially manufactured drill is needed to get through. Still it takes months to drill a 7-km-deep hole. The heat plant itself will be completed in 2018, and it is planned to cover 10% of the district heating needed in Espoo. If the pilot succeeds the technology can also be taken into use elsewhere in in the Nordic countries.
