United Kingdom: The "Grandfather of Geothermal" Answers Questions on the History of Geothermal Exploration in Cornwall

45 years of geothermal in Cornwall - some unanswered questions from Tony Batchelor (GeoScience)

From Rosemanowes to United Downs...........

Dr Tony Batchelor
Some of the staff from GeoScience Limited have been at the forefront of geothermal exploration and technology in the UK for over 40 years. These staff were involved in the Hot Dry Rock (HDR) project back in the 1980s, and are now working on the next chapter.

Now that the United Downs Deep Geothermal Power (UDDGP) project is drilling there are a few questions that a lot of people have been asking about the previous HDR project; dubbed the ‘grandfather of geothermal’ by Sir Tim Smit, Dr Tony Batchelor gives some answers;

Why did the project at Rosemanowes come to an end?

Rosemanowes was a jointly funded experiment by the UK Department of Energy and the EU operated by the Camborne School of Mines (CSM). The original work started at CSM in November 1973. We had various multinational collaborations including staff from the USA. The aim of the project was to test if we could circulate water through the Cornish granite and extract heat.

Netherlands: Use of Geothermal Heat for Greenhouse Horticulture Expected to Expand

“Westland greenhouse horticulture energy supply moving towards multiple sources in 2030” (

In each of the scenarios it is anticipated that the use of geothermal energy, heat from third parties and purchased electricity will grow. 

Towards the year 2030, far-reaching changes are foreseen for greenhouse horticulture in the Westland region. Expectations range from pessimistic, to moderate and even optimistic, according to research by Wageningen Economic Research commissioned by Capturam. 

The biggest change will be in terms of energy supply, as they will rely less on natural gas and more on sustainable sources and purchasing heat and electricity from third parties. This stems from a changing energy demand and sector structure, government policy and sustainability efforts of greenhouse horticulture companies and their partners. This shift in energy sources will have a favorable effect on the reduction of CO2 emissions and the increase in the share of renewable energy.

In each of the scenarios it is anticipated that the use of geothermal energy, heat from third parties and purchased electricity will grow. 

Costa Rica: 55 MW Borinquen 1 Geothermal Power Project Postponed - Report

Costa Rica Suspends the Largest Hydroelectric Project in Central America Indefinitely (The Costa Rica News)

The indefinite suspension of the hydroelectric project is due to the fact that the so-called Generation Expansion Plan determined that ICE has the installed capacity to meet the electricity demand of the next decade, the president of the state-run Costa Rican Electricity Institute (ICE), Irene Cañas said at a press conference.

For this reason, several projects under execution will also be postponed, such as the geothermal Borinquen 1, which was scheduled to enter into operation in 2024 but is now projected for 2026, and pre-investment studies of other energy initiatives will be reprogrammed.

Cañas indicated that Costa Rica’s electricity demand has been decreasing in recent years due to factors such as the incorporation of new technologies, the change in consumption patterns, energy efficiency policies, the migration of the manufacturing process industry to services, and the economic contraction.

Latin America and Caribbean Region: Tremendous Potential for Geothermal Energy - World Bank

Opportunities and Challenges for Scaling-up Geothermal Development in Latin America and Caribbean Region (World Bank)

Geothermal energy can play a substantial role in meeting the energy needs of many Latin America and Caribbean Region (LAC) countries given the region’s vast potential. 

The majority of geothermal resources in the LAC region remain largely untapped, not only in Central America and Mexico where development is more advanced, but also in the Caribbean and in South America. If further explored and developed in a sustainable fashion, these resources could meet a significant share of the base load power needs of the region, at a competitive cost, resulting in direct economic and environmental benefits. 

This report is envisioned to be a decision-makers’ guide for assessing key challenges and measures to facilitate expanding geothermal development in LAC. 

USA, Nevada: Silver State Voters Want More Renewable Energy

Voters Will Face The Renewable Energy Ballot Question Again in 2020 (KTVN)

Voters moved Nevada one step closer toward more renewable energy in the state. 59 percent of voters checked yes to increase the amount of solar, geothermal and wind resources in Nevada.

However, since Question 6 proposes an amendment to the state constitution, it'll have to pass again in 2020.

"In a state where we have an abundance of sunshine, geothermal and wind, we need to use it,” says Kyle Roerink, with Nevadans for a Clean Energy Future. "Currently we're at a 25 percent by 2025 renewable portfolio standard,” says Roerink. But because Nevadans approved Question 6, we're now on a path that would change that requirement to 50 percent clean energy by 2030."

United Kingdom: Drilling Completed at Penzance Geothermal Pool

Jubilee Pool geothermal spa in Penzance to open by Easter 2019 (Cornwall Live)

It will be like Iceland's Blue Lagoon but in Cornwall and the first of its kind in the UK

The date for when Penzance's iconic open air sea pool will become the UK's first geothermal heated spa has been revealed.

The boss of Geothermal Engineering Ltd, the company which has been drilling holes into the earth below the famous Jubilee Pool to tap into the earth's natural heat, said the tourist attraction will be ready to welcome its first visitors once more by Easter 2019.

Ryan Law, managing director at GEL, told Cornwall Live that the drilling has now been done under Britain's largest sea-water lido.

He said: "We've done the drilling. Now over the next five months we will put the equipment in place and carry out the structural work underneath the pool. Our aim is to have it all complete by Easter next year."

New Zealand: Research to Test Hypothesis that Surface Gases from Rotorua Geothermal Field Actually Come from Deep Underground

Two new GNS Science projects win funding from the prestigious Marsden Fund (News Release)

Project leader
Isabelle Chambefort
A research project at GNS Science that will investigate the emission of greenhouse gases from volcanic areas in the North Island has won funding in this year’s round of the prestigious Marsden Fund.

This project has been awarded $958,000 over three years to test a hypothesis that geothermal gases, which comprise many gases but mainly carbon dioxide, originate from eight or more kilometres below the ground and find their way to the surface via weaknesses in the Earth’s crust.

Such a finding would overturn the view that these gases come from much shallower geological features.

It is well established that about 1000 tonnes of carbon dioxide is released into the atmosphere from the Rotorua geothermal field every day. But there is little understanding of where the gas comes from or the pathways used to get to the surface.

Project leader Isabelle Chambefort said her team will use a combination of isotope analysis of gases and measurements of gas flows at the surface to trace the origin, transport, and interaction of gases in the Taupo Volcanic Zone.

Kenya: The Importance of Geothermal Energy to Continuing Economic Development

Kenya straddles a volcanic rift. It’s a green-energy geyser (National Geographic)

In 2010 fewer than one in five Kenyans had electricity. Now some 60 percent do—thanks mostly to geothermal power from the East African Rift

The percentage of Kenyans with access to electricity nearly tripled during that period, from 19 percent to 56 percent.

A key reason is the rapid expansion of geothermal power generation. Geothermal electricity, mostly produced here in Olkaria, now accounts for 28 percent of Kenya’s grid capacity, and its importance is only set to grow. It’s relatively clean and low-carbon, and in the long run it’s relatively cheap. And unlike other renewable sources such as solar, wind, and even hydro, geothermal is available year-round and around the clock. On some days right now, half the power used in Kenya comes from inside the earth.

“The reliability of geothermal plants is very high because steam is not affected by the vagaries of weather,” says John Omenge, until recently head of geo-exploration at Kenya’s Ministry of Energy. “This is the main reason why we’ve increased our geothermal focus. It has become our source of baseload power.”

Kenya: Minister Suggests Diversification of Uses for geothermal Resources

Kenya to Enhance, Diversify Utilization of Geothermal Resources (Jomo Kenyatta University of Agriculture and Technology)

Kenya intends to enhance the utilization of geothermal resources for electricity generation and diversify to other innovative direct uses such as recreational, agricultural and industrial applications, among others.

The Principal Secretary, Ministry of Energy, Dr. Eng. Joseph Njoroge, revealed this in his remarks to participants during the official opening of the two-day International Forum on Geothermal Technology at Jomo Kenyatta University of Agriculture and Technology (JKUAT), Tuesday, November 6, 2018.

“This will require constant human interactions and interventions in areas such as capacity building, reservoir engineering to improve success rates in drilling programmes, efficient power generation technology, optimizing fluid re-injection and recharge and minimizing loss through evaporation to ensure sustainable exploitation of geothermal resources,” said Eng. Njoroge.

Taiwan: 8 MW Yilan Geothermal Power Project Begins

Taipower, CPC join hands to explore geothermal power in Yilan (Focus Taiwan)

State-run Taiwan Power Co. (Taipower) and oil refiner CPC Corp., Taiwan kicked off a joint plan Wednesday to explore geothermal energy in Yilan County, northeastern Taiwan.

A ceremony was held at the site of the planned Renze No. 3 Geothermal Well in Yilan to mark the beginning of the exploration plan, under which work will be undertaken to drill a total of six exploratory wells in Renze and neighboring Tuchang before June 2021, according to the two companies.

CPC Chairman Tai Chein (戴謙) said the exploration project, estimated to produce an installed capacity totaling 8 megawatts of electricity if successful, is being carried out in three stages, with the first stage involving the drilling of two 1,500 meter-deep wells at a cost of NT$130 million (US$4.23 million).

The planned wells -- one of which will be a production well and the other a re-injection well -- are estimated to yield an installed capacity of about 2 MW, Tai said, anticipating that the exploration will be a success.

Kenya: Draft Legislation Lays out Royalties Schedule for Geothermal Energy

Hot topic: Reforms seek to tap geothermal assets to support regional development and improve fiscal solvency (OxfordBusinessGroup)

A new Energy Bill – which completed its public consultation phase in February 2018 – may result in a significant shake-up of Kenya’s geothermal segment. Significantly, the draft legislation lays out a royalties schedule. The raft of laws has been passed by the National Assembly but was still awaiting Senate approval as of September 2018. The bill will see geothermal firms pay fees of between 1% and 2.5% of the revenues generated from the energy source during their first decade of operation and 5% thereafter.

The proposed royalty on profits is a standard model in the international geothermal market. For example, the US has deployed a similar framework for decades, applying a modest rate of 1.75% for the first 10 years of production, before moving companies to a royalty rate of 3.5% thereafter. Nevertheless, establishing the precise rates constitutes a challenging undertaking. Geothermal resources of Kenya’s size are strategically vital to economic development; ensuring energy security, generating employment and providing income, in the form of rent, for landowners.

USA, Nevada: Ormat Reports More Than 5% Increase in Geothermal Electricity Revenues

Ormat Technologies Reports Third Quarter 2018 Financial Results (News Release)

Ormat Technologies, Inc. today announced financial results for the third quarter ended September 30, 2018.

“Total revenues increased nearly 6% and electricity revenues increased more than 5%,” commented Isaac Angel, Chief Executive Officer. “This steady growth was achieved despite the recent shutdown of our operations at Puna and highlights the diversification we have built into the Ormat operating model and the strength of our overall portfolio of projects around the world.  Now that the lava flow near Puna has ceased, we are working to bring that plant back online, and are confident that Ormat is well positioned for continued growth.”

Recent Developments:

  • Ormat completed the closing of the first tranche under the previously announced finance agreement totaling up to $124.7 million for the 35 MW Platanares geothermal power plant in Honduras, with the Overseas Private Investment Corporation (“OPIC”), United States government’s development finance institution, as the sole lender. Following the closing, Ormat received a disbursement of $114.7 million representing the full amount of Tranche I of the OPIC non-recourse project finance loan that carries a fixed interest rate of 7.02% per annum with a maturity of approximately 14 years. The closing of the second tranche of up to $10 million is expected during the first half of 2019.
  • In Puna, Hawaii, before the lava recently stopped flowing, the lava covered the wellheads of three geothermal wells, the substation of the Puna complex and an adjacent warehouse that stored a drilling rig. The Company is currently assessing the damages to the Puna facilities and continues to coordinate with Hawaii Electric Light Company and local authorities to bring the power plant back to operation. The Company is in the process of building access roads to the site, removing the plugs from the production wells and rebuilding the electrical substation. Management is in ongoing discussions with its insurance companies, working to secure a business interruption claim for the income loss from the shutdown.
  • Ormat opted out of the Galena 2 PPA with NV Energy Inc., and reported a one-time $5 million termination fee, recorded in selling and marketing expenses, in the third quarter of 2018. In March 2019, Ormat will start selling power from Galena 2 under its existing Southern California Public Power Authority portfolio PPA at $75.5 per MWh replacing lower pricing under the Galena 2 PPA.

United Kingdom: United Downs Geothermal Power Project - “It’s a make or break moment for geothermal power in the UK,”

Cornish geothermal drilling operation aims to prove UK potential (Financial Times)

Experts believe 5% of UK electricity supply could come from the clean energy source

Ryan Law, managing director of
Geothermal Engineering Ltd (GEL)
“It’s a make or break moment for geothermal power in the UK,” Ryan Law, managing director of Geothermal Engineering Ltd (GEL), told the Financial Times of the project named after the United Downs industrial estate it is in. “If this one doesn’t produce I don’t think we’ll see any others for some time.”

“It is a demonstration plant of a concept. And if that concept works we know we’ve got similar geology in many, many other sites across Devon and Cornwall,” said Mr Law. If it works he wants to create more joint direct heat and power generating plants in the region.

“To me the big thing about geothermal was always that you have . . . an absolutely low carbon energy source, that enables you to not be dependent on tides, to not be dependent on wind, not to be dependent on day or night in terms of solar,” said Lord Teverson, who chairs the Lords EU energy and environment select committee.

“The big problem, the Achilles heel, is that geothermal itself really can’t afford its exploration risk,” said Tony Bachelor of consultancy GeoScience, which is financially backing GEL.

New Zealand: Contact Energy Weighs its Future Geothermal Options

Contact Says Earnings Ahead of Last Year, Eyes Geothermal Options

Contact Energy says its operating earnings during the past four months are ahead of last year.

The company, which has simplified its business to improve its retail and generation margins, generated 3,158 GWh of electricity in the four months through October, about 8 percent more than the year before.

The company said it will keep working to lower the costs of its geothermal operations, which provide baseload electricity but need to remain competitive with the combined ability of wind and hydro-power stations to work together also to produce baseload.

Contact says it has a range of geothermal generation options at Wairakei and on the nearby Tauhara field that can be developed depending on demand.

While the resource consents for the original Wairakei plant expire in 2026, Contact says there is a compelling case for future generation development there, given the fluid volumes available beyond the requirements of the company’s Te Mihi and Poihipi plans.

The company has consent to build a third unit at Te Mihi, but notes it has alternatives, including re-powering Wairakei or building a new plant, which would require less capital.

Contact says its consented 250 MW Tauhara development remains the country’s “pre-eminent” renewable option.  But it says that field also lends itself to staged developments and that a brownfield development of the existing Te Huka plant is also attractive.

Chief executive Dennis Barnes noted those options will only be developed if they are backed by observable demand or contracts.

Science & Technology: Method for Desalination Using Geothermal Energy

A carbon neutral solution for desalination? Maybe so by tapping into geothermal (EurekAlert)

At the end of the process, distilled water would be available for consumers and aquifer storage, and the chilled water could be used in air conditioning for the plant. The whole theoretical system is carbon-neutral. (Courtesy Thomas Missimer)
Scientists at Florida Gulf Coast University have proposed a carbon-free way to desalinate water using geothermal energy.

With water shortages increasing and rising global temperatures exacerbating drought conditions, countries such as Saudi Arabia are turning to desalination plants to provide drinking water to their residents.

But the method requires a high amount of energy, which can limit the use of the process in many parts of the world.

“We’re searching the world right now for better methods, low carbon methods, to create energy,” said Thomas Missimer from Florida Gulf Coast University. “We want electricity that’s generated at base load — in other words, generated 24 hours a day without interruption. Geothermal is one of those types of energies.”

Dry rock geothermal potential is more wide-spread globally. Missimer suggests using these areas—regions like southern California, North Africa, and the Red Sea region — to heat water that can be used to produce energy.

USA, Oregon: More than 595 MW of High Probability Capacity from Conventional Geothermal Resources

2018 Biennial Energy Report (Oregon Department of Energy)

The inaugural Biennial Energy Report provides foundational energy data about Oregon. It also examines the existing policy landscape and identifies a number of options for continued progress toward meeting the state’s goals in the areas of climate change, renewable energy, transportation, energy resilience, energy efficiency, and consumer protection.

Geothermal in Oregon

The state’s first geothermal power plant began operating in 2010 at the Oregon Institute of Technology (OIT) in Klamath Falls, with an initial electricity- generating capacity of 280 kW. A second plant at OIT generates 1.2 MW of  power. In 2012, a 28 MW geothermal power plant near Vale came online. Additional geothermal opportunities are being explored at Crump Geyser and Glass Butte in Lake County and at Newberry Crater.

Resource Potential

In the United States, most geothermal reservoirs are located in the western states, and Oregon has one of the best geothermal resources in the country. The U.S. Geological Survey’s Assessment of Moderate and High Temperature Geothermal Resources of the United States identified 595 MW of high probability capacity in Oregon from conventional geothermal resources.

The same report also identified more than 43,000 MW of potential capacity in Oregon from enhanced geothermal systems (EGS). EGS requires the injection of high-pressure water to modify subsurface conditions to enhance flow and permeability. While the potential to develop EGS in Oregon is significant, the technology is still in the research and development phase, and the U.S. Department of Energy has targeted 2030 for commercialization of the technology.

USA, South Dakota: Research on How Geothermal Hydro-Shearing Impacts Rock in Deep Underground Wells

Sanford Underground Research Facility studying geothermal fracking (Rapid City Journal)

(Courtesy Rapid City Journal)
The SIGMA-V experiment is part of a larger project out of the Lawrence Berkeley National Lab that began Oct. 1 in the Sanford Underground Research Facility, or SURF, that seeks to find out how geothermal fracking impacts rock in deep underground wells.

Typically, "fracking" is not considered a clean energy. Engineers push water and fluids into shallow wells to extract hydrocarbons, such as natural gas, but the byproducts are the stuff of headlines: water from faucets in Appalachia able to be lit on fire or seismic tremors in Oklahoma near wells. But geothermal fracking is much deeper and involves only water.

"We're talking green energy here," said Bill Roggenthen, a seismologist with South Dakota School of Mines and Technology in Rapid City. "No CO2, no methane. Geothermal energy is, well, pretty cool, but really we're talking about utilizing heat that is coming out of the earth in a responsible manner."

Indonesia: Geothermal Power Plants in West Java Produce 1,194 MW

West Java produces 61% of national geothermal energy (Jakarta Post)

Energy and Mineral Resources Ministry geothermal director Ida Nuryatin said on Friday that total non-tax revenue from the geothermal energy sector in West Java has reached Rp 1.1 trillion (US$72.86 million) so far this year.

Ida said that of the total revenue, 80 percent was for the West Java administration and 20 percent for the central government.

West Java produces 61 percent or 1,194 megawatts (MW) of the 1,948 MW national geothermal energy production.

“We have abundant potential geothermal energy in West Java compared to other regions. We have seven geothermal power plants in West Java,” she said, adding that the power plants were located in Kamojang, Salak, Darajat, Wayang Windu, Patuha, Karaha and Cibuni.

She explained that the one in Cibuni, which is in a pre-production phase, would have an installed-capacity of 30 MW once it came on stream.

Last weekend I was invited, together with members of the Cornish Institute of Engineers (CIE), to visit the United Downs Deep Geothermal Power (UDDGP) project in the old copper mining district.

Commencing tomorrow, two deep holes (wells) will be drilled; one for injection at about 2,500m depth and one for production at 4,500m. The temperature at the bottom of the production well is expected to be about 190°C. Water will be pumped from the production well, fed through a heat exchanger and then re-injected into the ground to pick up more heat from the rocks in a continuous cycle. The extracted heat will be used to supply a demonstration power plant.

Drilling such deep wells in very hard rocks requires a large drilling rig, similar to those normally used for oil, gas and conventional geothermal wells and it is estimated that it will take between six and seven months to drill the two wells, operating 24 hours a day.

The project aims to prove the technical and commercial viability of generating electricity from geothermal energy in Cornwall, so if the drilling and testing is successful UDDGP will build a small demonstration power plant and supply power to the grid.

Boost to Nakuru farmers as county partners with GDC to incorporate geothermal power in farming (hivisasa)

Farmers in Nakuru County have a reason to smile after the County’s Department of Agriculture, Livestock and Fisheries partnered with Geothermal Development Company (GDC) to fully incorporate geothermal power into their farming.

GDC plans to drill more wells in the densely populated and farming areas such as Ol Rongai, Kwa Gitau, Rigogo, Boito, Ngata Farm, Menengai Station and Kabarak.

GDC environment manager Gabriel Wetang’ula said that apart from the use of steam in the generation of electricity, geothermal can be used in heating greenhouses, milk pasteurization, laundry, leisure and recreation.

Netherlands: Progress in Realising a Geothermal Well on TU Delft Campus

Geothermal research at TU Delft gets a boost (News Release)

While most people did not think about heating their houses during the last hot summer months, researchers at TU Delft did exactly that (and not just the last months). Scientists involved in geothermal research have good reasons to look forward: the Board of the University has made a decision-in-principle for a next step towards realising a geothermal research well.

TU Delft is doing research on new materials and innovative ways of monitoring subsurface processes and was recently awarded more than 5 million euro for scientific equipment of a geothermal research well by NWO (EPOS-NL project).

The well will supply campus buildings with heat. In the future further research could be done on extending the heat grid further. TU Delft is proud to work on a sustainable campus, where electricity is already provided by solar panels on TU buildings and an off-shore wind park. Heating campus buildings with geothermal energy would bring TU Delft a big step towards being 100% CO2-neutral.

Africa: Seventh African Geothermal Conference Opens in Rwanda

Africa should look to geothermal to address its energy deficit, experts say (The New Times)

African countries should exploit their geothermal energy potential in order to cater for the growing demand of electricity, which is partly driven by the continent’s sustained robust growth, according to industry experts.  

The experts made the call yesterday during the seventh African Geothermal Conference (ARGeo-C7).

For example, they said, the Great Africa Rift Valley alone has over 20,000 MW of geothermal energy yet only a fraction of that is exploited.

According to Juliette Biao Koudenoukpo, the Regional Director of UN Environment in Africa, governments should be ready to remove barriers that can hinder the attraction of private investors if they are to succeed in geothermal development.

“Public investment cannot really achieve those targets, no private sector can come on board if the risks are not mitigated, if the environment is not conducive and if there is no incentive for them to come, the private sector will only come for profit,” she said.

Philippines: Successful Delisting will Support Geothermal Developer's Long-Term Growth

EDC completes tender offer (BusinessWorld Online)

Energy Development Corp. (EDC) has completed its tender offer for its planned exit from the Philippine Stock Exchange (PSE).

In a disclosure to the stock exchange on Wednesday, the Lopez-led company said shareholders holding a total of 2.01 billion common shares accepted the tender offer priced at P7.25 apiece. The enter tender offer size was 2.04 billion common shares.

The buyback of shares from the public forms part of the company’s plan to voluntarily delist from the stock exchange. The company said this will help them pursue a corporate strategy that would require greater flexibility over factors such as its dividend policy and leverage. The delisting is also seen to support EDC’s long-term growth.

EDC holds nearly 1,200-MW of geothermal capacity, which accounts for 61% of the country’s total installed geothermal capacity.

Coca-Cola Femsa said in a statement it strived to make clean energy a more prominent part of its global manufacturing processes, in keeping with its long-standing commitment to reduce its carbon footprint and to achieve sustainable operations through the use of renewable energy sources and the adoption of new technologies to further enhance operational efficiency.

Hungary: PannErgy Reports Good Testing Results at Győr Geothermal District Heating Project

Geothermal system of Győr deployed, final test results of the new production well in Bőny (News Release)

After the successful deepening operation on the BON-PE-03 well that PannErgy Concession Ltd implemented in the framework of a concession-based investment, the well pump has been installed at a depth of 830 meters with the connection of the well to the geothermal system of Győr also completed. Unmatched in Hungary, the system constructed with three production wells has yielded the first test results under continuous live operating conditions for the pump-assisted BON-PE-03 well and the other two free-flowing wells.

The results indicate that in terms of energy volume equivalent the system approximates the earlier targeted 1100 m3 /hour increase in the combined thermal water extraction capacity by featuring a maximum yield of only 1065 m3
/h, while the temperature measured on the secondary line (towards AUDI and Győr-Szol) is approximately higher by 1 (one) Celsius degrees, (difference between the average inlet and outlet temperature (ΔT) that is directly proportional to the volume of energy, and is therefore higher by 2.1%), and therefore the green heat volume that can be delivered is at 98,9% of the expected level. The capacity of the BON-PE-03 production well with pump-assisted extraction reaches 765 m3 /h. Based on the evaluation of the results – as depending on the prevailing weather conditions – the expanded system is foreseen to be capable of delivering 840-850 TJ green heat annually in the current consumer structure, with the supply of less than expected electric power.
