First it was the Celts, who worshipped at the waters bubbling up from beneath the surface of the earth, then the Romans, who created a complex of baths and steam rooms to harness the power of the sacred springs.

Now 21st century engineers are to use the water from the same hot springs beneath the city of Bath to heat its medieval abbey.

Builders will shortly begin work on an underfloor heating system using the waters from the springs which supply the historic Roman baths.

The scheme, being funded by the Heritage Lottery Fund, envisages 1.5 megawatts of continuous energy being produced, enough to heat the church and surrounding buildings, as well as the Romans Baths and Pump Room complex itself.

Indonesia: Star Energy Issues Green Bond to Further geothermal Energy Development

Star Energy Geothermal Wayang Windu publishes a green bond for US $ 580 million (Business Insight)

Wayang Windu geothermal power plant (PLTP) operator, Star Energy Geothermal (Wayang Windu) Ltd (SEGWW), has recently completed an environmental bond offering or green bond worth US $ 580 million. The subsidiary of Star Energy Group Holdings Pte Ltd has set a coupon of 6.75 percent.

The bonds will be issued as of April 24. With a 15-year tenor, the notes will mature on April 24, 2033. The first coupon payment is scheduled for October 24, 2018.

Refinancing through bank loans is a Star Energy strategy because it requires quick funds to acquire two of Chevron's geothermal assets, namely Salak geothermal field and Darajat geothermal field. In March 2017, Star Energy completed the $ 2.3 billion acquisition through a consortium with AC Energy (Ayala Group's Philippine energy business arm) and Thailand Electricity Generating PCL (EGCO) power producer.

Policy: Geothermal Power Should Increase to 227 GW by 2050 to Help Mitigate Climate Change - IRENA

Global Energy Transformation: A Roadmap to 2050 (IRENA)

The REmap Case 2050 target for geothermal energy is 227 GW

Renewable energy needs to be scaled up at least six times faster for the world to meet the decarbonisation and climate mitigation goals set out in the Paris Agreement, says Global Energy Transformation: A Roadmap to 2050.

The total share of renewable energy must rise from around 18% of total final energy consumption (in 2015) to around two-thirds by 2050. Over the same period, the share of renewables in the power sector would increase from around one-quarter to 85%, mostly through growth in solar and wind power generation.

Finance: Report Identifies Key Barriers and Highlights Policy Options to Boost Geothermal Energy Deployment

Renewable Energy Policies in a Time of Transition (IRENA)

This report, prepared jointly by the International Renewable Energy Agency (IRENA), the International Energy Agency (International Energy Agency (IEA) and the Renewable Energy Policy Network for the 21st Century (REN21), identifies key barriers and highlights policy options to boost renewable energy deployment.

After reviewing current policies and targets worldwide, it examines sector-specific policies for heating and cooling, transport and power, as well as measures for integrating variable renewables. An updated policy classification and terminology list can serve as a global reference for renewable energy policy instruments.

Supporting Geothermal Power by Reducing Risk

Global potential for geothermal energy is estimated at 70 to 80 GW. However, because of several barriers, only 15% of the potential capacity is being harnessed globally. One key challenge relates to the high risks and upfront costs associated with exploration, as well as overall project development costs, which occur over a relatively longer period of time.

To reduce the risks associated with geothermal development, several policy approaches and instruments have been successfully applied globally, including: full government development of the resource; cost-sharing between the government or donors and the private sector to mitigate risk; use of insurance instruments and loan guarantees; and application of other fiscal incentives (e.g. tax and import duty exemptions). Key features enabling successful implementation of geothermal projects under various policies include: sufficient capacity within the private sector to implement projects through a multistage (and time-consuming) process; development of transparent and clear criteria to select project development partners; and provision of clear information
on risk capital to be mobilised.

Kenya, Turkey and Nicaragua have been successful in reducing risk through government-supported early-stage drilling with project development undertaken by the private sector. The Geothermal Risk Mitigation Funds for Africa and the Geothermal Development Facility for Latin America are supported by several
donors and providing co-funding for early-stage exploration and certain project development costs. The facility also provides further risk mitigation through allowing for conversion of the co-funding into a full grant (with no further financial obligation) in cases where drilling is unsuccessful.

Italy: Enel Announces Award for Mercury and Sulphurized Hydrogen Reduction System for Geothermal Power Plants

Geothermal: Innovation Comes from an Alliance between Business and Research (News Release)

A winner has been chosen for the challenge launched by Enel Green Power to identify innovative solutions to use at geothermal plants. The winner of the 15,000-euro prize is Luigia Lona, a researcher-entrepreneur with “an innate instinct to search for solutions”.

“An innate instinct to search for solutions” and the belief that “true, effective innovation comes from the close relationship between research, application and business”. These are the two key factors that inspired Luigia Lona to participate in and win the challenge launched by Enel Green Power to make Mercury and Sulferized Hydrogen Reduction (AMIS) systems in EGP geothermal plants more effective.

The winning idea involved a change in the last stage of the AMIS cycle, where soda is used to regulate the level of acidity in the liquid solution coming from the H2S reduction process. Specifically, the change involves halving the entry of soda in the scrubber and introducing a system that allows for the optimisation of the quantity of soda consumed for different sections.

Finance: Geothermal Energy Favors Well in External Cost Comparison

Accounting for The Full Cost of Electricity (News Release)

The market price of generating electricity doesn't necessarily account for the social and environmental impacts of its generation, says the Organisation for Economic Co‑operation and Development Nuclear Energy Agency (NEA) in its new report The Full Costs of Electricity Provision.

"What this report reveals is that the notion of "electricity cost" that we often use today, the levelised costs of electricity (LCOE), is just a part of a much bigger picture. While LCOE is a useful tool to compare the costs of baseload technologies in regulated systems, it leaves out many decisive aspects of the costs of electricity. In particular, the grid‑level system costs and the social costs that are not captured by LCOE are too important to be ignored any longer" said NEA Director‑General William D. Magwood, IV, at the report's launch.

Indonesia: PT Supreme Energy Boss Reaffirms Commitment to Geothermal Energy Projects

Supramu Santoso: It’s Challenging, but We Stick in Geothermal (TheInsiderStories)

TheInsiderStories interviews President and CEO of PT Supreme Energy Supramu Santoso.

Q: How is the progress of Supreme’s Business? We will start the construction of geothermal plants in June this year and targets the operation in 2020. It takes around three years. The project capacity is 91 megawatt.

Q: It is your first project? No, we earlier drilled some geothermal wells, but we should continue to drill around 13 wells. We currently have three geothermal concession in West Sumatra, South Sumatra, and Lampung.

Q: How much is the potential power capacity of the project? Around 80 megawatts in West Sumatra project.

Q: How about the other projects? In South Sumatra project, we will start drilling in July this year. For Lampung project, we hope we can build a road to the project this year.

Q: How much is the total capacity of the project? We do not know. It depends on. It is difficult to estimate. In the past, we expected around 600 megawatts for the three projects but the exploration result is different. So we do not dare to estimate, we hope to discover around 200 megawatts.

Q: Do you have a project that already in production phase? The West Sumatra project will (come) on stream on 2019, (with) approximately 86 megawatt of gross production.

Q: The renewables business faced many obstacles, but are your company stick in this industry? When we first entered the geothermal industry, it was very promising. The energy demand projected to grow around 9% per year while the oil and gas production dropped. In addition, Indonesia has huge geothermal sources. So, I was thinking that it’s a good investment, but it is not easy.

Taiwan: Government Urged to Build Geothermal Power Plant Instead of Coal-Fired Plant

Forum proposes geothermal power plant for Shenao (The Taipei Times)

The government should stop planning coal-fired facilities at the Shenao Power Plant and instead consider a geothermal energy plant, environmentalist Kao Cheng-yan (高成炎) told an annual meeting of Taiwanese non-governmental organizations (NGOs) yesterday.

Kao, who was one of two people to be granted a lifetime achievement award at this year’s meeting, yesterday urged the government to replace the two coal-fired generators planned at the Shenao plant with geothermal facilities in a bid to avoid more air pollution and carbon emissions from coal combustion.

The plant’s planned location is only about 7km from the volcanic Keelung Islet (基隆嶼) and is thus well-situated to host a geothermal plant, he said.

USA, California: Community Choice Aggregator Gets 240 MWh Geothermal Power a Year from The Geysers

The Power of The Geysers (Silicon Valley Power)

At a state-owned facility 72 miles north of San Francisco, a powerful force deep underground is harnessed to supply almost five percent of California’s electricity. The facility, known as The Geysers, taps into a reservoir of steam over two miles below ground and turns it into usable electricity. Each year, this steam generates up to 5.5 million Megawatt-hours (MWh) of power, making The Geysers the largest geothermal field in the world.

Luckily for Santa Clara (through Silicon Valley Power), we have invested in this renewable, reliable power resource. Through the Northern California Power Agency (NCPA), we co-own two geothermal plants at The Geysers. Together, our plants produce up to 240 MWh of power each year – enough to power as many as 240,000 homes among our combined customers.

Kenya: Plans to Replace Feed-in-Tariff System With Energy Auction Tariff

Kenya to scrap current feed-in-tariff system (Kenya Broadcasting Corporation)

Kenya plans to scrap the current feed-in-tariff system and replace it with an energy auction tariff that will see the government award energy contracts to companies’ offering the lowest electricity tariffs.

Director of Renewable Energy at the Ministry of Energy Isaac Kiva says the auction model will replace the current feed-in-tariff system where investors identify potentially viable power projects and then acquire licenses to operate them at predetermined rates.

For the last ten years, Kenya has been using the feed-in-tariff model where investors interested in investing in wind power, geothermal, solar, hydropower and biomass energy sources are offered a power purchase agreement to construct the power plant and sell the electricity to Kenya Power.
However, the model has been criticized as being responsible for making power tariffs expensive.

Science & Technology: Method for Increasing the Extraction of Rare Earth Elements from Geothermal Brine

Decreasing the magnetism of metallic core particles with a metal-organic framework shell (Phys.Org)

Surface mining for rare earth elements used in smartphones and wind turbines is difficult and rarely done in the United States. Scientists wanted to know if they could pull the metals, present at trace levels, from geothermal brines using magnetic particles. The particles, wrapped in a molecular framework shell known as a metal-organic framework, or MOF, should easily trap the metals and let the rest flow past. However, the team led by Pete McGrail at Pacific Northwest National Laboratory found the magnetic strength dropped by 70 percent after the MOF shell was formed.

The use of MOFs may allow for the separation of yttrium, scandium, and other elements from saline water from geothermal sources, produced waters from oil and gas fields, or wastes such as fly ash.

The team showed that the chromium penetrated into the pores in the iron particles and was reduced by capturing an electron from the iron thus oxidizing it. The magnetic strength of magnetite is strongly determined by the amount of ferrous versus ferric (oxidized) iron in the material. The iron oxidation thus degraded the magnetic properties. These fundamental insights will allow materials science researchers to adjust the MOF chemistry to prevent the unwanted oxidation-reduction reactions and better retain the core-shell material's magnetic properties.

Turkey: 4,000 MW of Geothermal Energy by 2030 is New Target

Turkey's geothermal target for 2030 quadruples (World Bulletin)

Turkey has already superseded its 2023 target for geothermal installed capacity which prompted a revision up of the 2030 target to 4,000 MW, General Directorate of Renewable Energy (YEGM) chief said on Wednesday.

Speaking at the opening session of Geothermal Turkey Workshop and Congress, held in Ankara, Oguz Can, the general manager of the YEGM, said that Turkey had a geothermal target for 2023 of 1,000 MW of installed capacity which has already been achieved.

"We, as the Ministry of Energy and Natural Resources, think that geothermal energy is a sector in which strategic and important developments need to continue,” Can explain.

He also added that in terms of capacity, the introduction and creation of new areas should be carried out systematically.

Can recommended that geothermal energy be used not only for electricity production but expanded out for the use in the agricultural sector.

Pakistan: Potential for Geothermal Energy Development

Renewables Readiness Assessment: Pakistan (IRENA)

Pakistan’s geothermal resources remain largely unexplored. No comprehensive assessment of the potential has been made nor does a policy framework exist to encourage private participation in the sector. Some scientific studies have located potential geothermal resource areas in the country.

Most of the world’s high enthalpy geothermal resources are within the seismic belts associated with zones of crustal weakness. One example is the seismotectonic belt that passes through Pakistan, which has a long history of geotectonic events (Zaigham, Nayyar and Hisamuddin, 2009). Thus the country in all probability has commercially exploitable geothermal resources.

The sporadic efforts to assess the potential have all concentrated on identifying geothermal phenomena and locating production zones. However, assessors need to go further and integrate their efforts. They need to estimate the size of the resource base, determine heat content of fluids and compile a comprehensive database (Zaigham, 2005).

Conscious of geothermal as a potentially valuable renewable energy resource, Pakistan became a member of the Global Geothermal Alliance in December 2015 and adopted the Florence Declaration at the alliance’s high-level ministerial
meeting in Florence, Italy, in October 2017. In so doing, Pakistan has joined the global commitment to a fivefold increase in geothermal power generation and a 100% increase in geothermal heat by 2030.

Science & Technology: Increasing Efficiency of Organic Rankine Cycle Geothermal Turbines

Performance Analysis Of Organic Rankine Cycles Using R600/R601a Mixtures With Liquid-Separated Condensation (Science Trends)

Liquid-separated condensation is an emerging enhanced heat transfer method that separates the condensed fluid from the vapor-liquid mixture during condensation. It reduces the condensing film thickness on the cooling surface and increases the vapor quality. 

The key idea is to use the excellent heat transfer characteristics of high-quality vapor to increase the condensation heat transfer coefficient, as shown in the figure above. Separating the condensed fluid also reduces the flow resistance during condensation. Therefore, liquid-separated condensation can simultaneously increase the condensation heat transfer coefficient and reduce the pressure drop.

Germany: Combined Heat and Power Tender for Projects Using Geothermal Energy or Heat pumps and Other Renewable Heat Sources

Germany starts 25-MW tender for CHP with renewable heat source (Renewables Now)

Germany today announced the start of its first innovative combined heat and power (CHP) tender in which projects have to use heat sources such as solar thermal, geothermal energy or heat pumps.

The tender will award contracts to 25 MW of projects, which will include a cogeneration plant, an innovative renewable heat source and a power generator. The deadline for offers is June 1 and the bid cap has been set at EUR 0.12 (USD 0.15) per kWh, Germany’s Federal Network Agency, or the Bundesnetzagetur, said.

The innovative CHP tenders in Germany are to help determine the role of CHP plants in decarbonising power and heat supply, the agency said.

In parallel with this tender, the Bundesnetzagetur will also hold Germany’s second normal CHP auction. The quota there is a bit over 93 MW and the maximum bidding price is lower, at EUR 0.07/kWh. The deadline for bids is the same.

Kenya: GDC Secures 40-Year Rights to Develop Geothermal Energy at Menengai

GDC secures 40-year lease for power generation site (Hivisasa)

Geothermal Development Corporation (GDC) has secured the lease area for the geothermal power generation project in Menengai for 40 years.

Speaking at the site, Managing Director Joseph Ole Nchoe said that Kenya Forest Service has granted them the rights and would go a long way to developing the project which is of national importance.

The last hurdle has been addressed after the African Development Bank offered to offer credit guarantees to the three Independent Power Producers to each start the process of constructing 35-megawatts capacity power plant.

The GDC MD expects that the three IPPs will complete construction of the power plants and start generating 105 megawatts to the national grid by end of next year.
