Science & Technology: Researching Corrosion Resistant Coatings for High Temperature Geothermal Applications

Investigating geothermal coatings for the future of renewable energy (TWI)

TWI, an U.K.-based independent research and technology organisation, is co-ordinating a recently won European Horizon 2020 project for the development of novel and cost-effective corrosion resistant coatings for high temperature geothermal applications. This project, dubbed Geo-Coat, comes from the low carbon energy call to develop next generation technologies for renewable electricity and heating/cooling.

Thus, the Geo-Coat target is to design the new high performance coatings to resist each of the specified threats or combinations of threat, as experimentally derived at key failure points within geothermal runs, and to apply them only to the affected components.

The project will last for three years, with the Geo-Coat partners coming from the UK, Iceland, Romania and Norway.

EERE is specifically interested in information on defining major challenges in geothermal drilling and identifying opportunities in research and development and process improvement. This is solely a request for information and not a Funding Opportunity Announcement. EERE is not accepting applications.

Responses to this RFI must be submitted electronically to geothermal.comments@ee.doe.gov no later than 5:00pm (ET) on January 22, 2018. All submissions received must include “Geothermal Drilling RFI” in the subject of the message.

United Kingdom: Field Site Described for Glasgow Geothermal Energy Research Center

UKGEOS: Glasgow Geothermal Energy Research Field Site (GGERFS): initial summary of the geological platform (BGS)

Monaghan, A.A. et al. Nottingham, UK, British Geological Survey, 205pp. (OR/17/006) (Unpublished)


The preferred second UKGEOS site is at Clyde Gateway, in the east end of Glasgow, Scotland. The focus of this, the Glasgow Geothermal Energy Research Field Site (GGERFS), is on characterising and monitoring the subsurface for minewater and hot sedimentary aquifer geothermal energy, and for cooling and heat storage.

This report details BGS data and knowledge at late 2016, to define initial characterisation of the ‘geological platform’ relevant for the planning of a geothermal research facility and associated environmental baseline monitoring. The report covers knowledge of the bedrock and superficial deposits geology, abandoned coal mines, hydrogeology, geothermal datasets, geochemistry, remote sensed data, seismicity, stress fields, engineering geology and rock property datasets.

BGS holds a great deal of legacy borehole, mining and geochemistry data and has updated existing bedrock and superficial deposits models of the area. However, deep borehole and seismic data are lacking to define the geology and structure of the area below a few hundred metres. Hydrogeological and temperature data are also lacking for the bedrock strata. Regional datasets and knowledge have (and can be further) used to reduce uncertainty and risk in these aspects of the geological characterisation.

United Kingdom: Geothermal Energy PhD at University of Glasgow

Geothermal Energy PhD with funding available for October 2018

Understanding blockages in active geothermal systems: insights from clumped isotopes (Ref IAP-17-43)

University of Glasgow (School of Geographical & Earth Sciences)
In partnership with Durham University (Department of Earth Sciences)


The main goal of this project is to use ‘clumped’ isotopes to investigate the conditions at which calcite precipitates in fractures in active geothermal systems.
The clumped isotope method has great potential as a proxy for reconstructing past temperatures in a range of geological settings. This method is based on the
temperature dependence of bonds between heavy carbon (13C) and oxygen (18O) isotopes in the carbonate mineral lattice.  The principal supervisor can be contacted at: john.macdonald.3@glasgow.ac.uk

Japan: Low Temperature Geothermal Power Market to Expand - Report

Low Temperature Geothermal Power in Japan (Frost & Sullivan)

New Horizons for Clean Power Generation from Low Temperature Geothermal Energy

Geothermal power only contributes a meagre 0.3% of total electricity generation, despite the country possessing the third largest geothermal resource in the world, representing a power generation potential of 23 GW.

While the government has been proactive in recent initiatives to identify and promote potential areas for exploration and development, there has not been any significant development of geothermal power in the country in the last decade.

However, despite stagnation in development of the technology at medium and high temperatures, increased investment and technological innovation targeting low temperature geothermal power (<120°C), historically used primarily for heating purposes, are expected to significantly increase the addressable market potential for geothermal power and represent a new growth market in the country.

Science & Technology: Geothermal Powered Carbon Capture Explained

The science of capturing carbon (al Jazeera)

Scientists are fighting to curtail the dangerous effects of climate change by capturing carbon dioxide.


(Video 24:49 Minutes)

So, what if scientists could offset dangerous greenhouse gas levels by manually capturing CO2 from the atmosphere and then putting it to use in a cyclical, no-waste method?

One such project, run by a team of researchers in Iceland taking their cue from processes in nature, seeks to combine basalt and CO2. Basalt is naturally highly reactive with CO2; when the two meet, they undergo a series of exchanges that culminate with the carbon precipitating out as a solid whitish substance, similar to limestone.

"In our volcanic areas, we have volcanic CO2 interacting with our basalt, turning the CO2 into carbonate minerals. So then we thought why not test this interesting idea out here in Iceland. We have our geothermal power plant, providing a source of CO2 that then can be captured and injected back into the ground, and see if we can utilise and accelerate this natural process," says Edda Aradottir of Reykjavik Energy, home to carbon capture programme CarbFix.

"Once the CO2 is turned into stone, you don't have to worry about it, it's not going anywhere it's just buried in the ground as rock," she continues.

USA, Wyoming: Investigating Yellowstone Lake’s Hydrothermal Systems

Exploring the Restless Floor of Yellowstone Lake (EOS)

Yellowstone Lake, far from any ocean, hosts underwater hot springs similar to those on mid-ocean ridges. A research team is investigating the processes that drive the lake’s hydrothermal systems.

The vent fields on the floor of Yellowstone Lake are a significant part of the world’s largest continental hydrothermal system and thus form an important part of the Earth’s thermal budget and geochemical cycles.

Continental hydrothermal systems are a primary source of economically important metal deposits, provide geothermal energy resources, support exotic ecosystems that are just beginning to be explored, and, in some settings such as Yellowstone, pose significant geological hazards.

USA: Legislation Could Enhance Geothermal Production on Federal Lands

Labrador Introduces Bill Spurring Geothermal Exploration (News Release)

Legislation lifts regulatory hurdles to unleash clean energy development in Idaho and other federal land states

Rep. Raúl Labrador
(Wikimedia Commons)
Rep. Raúl Labrador, R-Idaho, on Wednesday introduced the Enhancing Geothermal Production on Federal Lands Act, a long-awaited bill to accelerate development of an abundant Idaho resource.

Ninety percent of viable U.S. geothermal resources exist on federal lands. In Idaho alone, the resource is estimated at 800 megawatts – enough to heat 500,000 homes.

H.R. 4568 would reduce regulatory approval waiting times for small exploratory wells from about 10 months to two months or less. Test holes 8 inches or less in diameter would be granted a categorical exclusion under the National Environmental Policy Act (NEPA). Similar provisions already exist for oil and gas exploration and mining.

The bill also permits coproduction of geothermal resources on lands leased for oil and gas; requires the government to identify priority areas for geothermal development; and authorizes noncompetitive, fair market value leasing by an existing leaseholder on adjoining lands. The leasing provision is drawn from H.R. 4252, a bill introduced in November by Rep. Mike Simpson, R-Idaho.

The Trias drilling for geothermal Westland Trias project in Naaldwijk, in the Netherlands, started a month ago. The drilling of the first section went well. The first section is about 1,300 meters deep. In the weekend of 18/19 November, the steel tube (casing) with a diameter of approximately 50 cm was inserted into the borehole. The space between the borehole and the outer wall of the casing was cemented to reinforce the borehole.

The drilling of the second section started November 29. The borehole in this section has a diameter of approximately 45 cm. The drilling runs smoothly with an average speed between 10 and 15 meters per hour. We expect to be finished with the drilling of this section in a few days time, having reached a depth of 2,550 meters.  A casing will then be inserted and reinforced with cement.

Europe: New Report Surveys Supply Chain for Geothermal Energy

Supply chain of renewable energy technologies in Europe: An analysis for wind, geothermal and ocean energy (European Union)

Geothermal power plants are currently installed in eight European countries of which six EU-28 Member States. Capacity additions in recent years took mainly place in Turkey where a strong growth can be observed from about 220 MW in 2012 to about 870 MW at the end of 2016 (Shortall & Uihlein, 2017).

The global market in geothermal power is dominated by four major manufacturers (Toshiba, Mitsubishi, Ormat, Fuji) accounting for about 80 % of the installed capacity (Annex et al., 2016). In Europe, Ansaldo-Tosi leads the market with about 30 % of installed capacity. Other prominent players in Europe are Mitsubishi-Turboden, Fuji, Ormat, and GE/Nuovo Pignone. Ansaldo-Tosi and GE/Nuovo Pignone are mainly active in Italy with capacity installed in hydrothermal power plants existing since a very long time.

The European market is still dominated by conventional dry steam/flash technology (65 % of installed capacity). However, the majority of recent installations are binary power plants. The main turbine suppliers after 2012 are Ormat (34 % market share, followed by Exergy and Atlas Copco with 22 % and 19 % of market share, respectively.

Denmark: Compensation Guarantee for Geothermal Projects

Geothermal Development: The Danish Compensation Guarantee (Wellperform)


Development of a geothermal well is a costly ordeal, and combined with the apparent risk of a low payback or even abandonment of the hole, the investors and stakeholders are left understandably precautious.

To encourage the pursuit of geothermal energy sources, a compensation guarantee has been put in effect per 2015 for projects in Denmark.

The compensation guarantee comprises a user charge, correlating to a percentage of the budget: 13.5% for the first well, and 9% for each following well. In return, the insurance policy covers three guarantees in total:
  • Drill Risk Guarantee: coverage of budget overruns while drilling. 
  • Total Damage Guarantee: partial coverage of drilling costs, provided the project must be abandoned due to technical problems. 
  • Reservoir Risk Guarantee: partial coverage of drilling costs, provided that the reservoir does not perform as expected.

USA: Consequences for Geothermal Electric Industry of New Tax Legislation

A Clean Energy Guide to the Tax Legislation Conference Committee (Rhodium Group)


Broad tax legislation advanced by the US Congress in recent weeks is headed toward a conference committee, where Republicans in the House and Senate will hash out their differences. In this article we identify which provisions matter most for clean energy.

Geothermal electric power plants currently have a permanent 10 percent ITC. Under the House bill, this would be eliminated in 2027. Geothermal would also likely get hit by the BEAT provision in the Senate bill, though not nearly as much as wind and solar due to less reliance on tax equity partners.

Science & Technology: More Efficient Method for Extraction of Lithium from Geothermal Brine

Recovery of Lithium from Geothermal Brine with Lithium–Aluminum Layered Double Hydroxide Chloride Sorbents (Environmental Science & Technology)

Mariappan Parans Paranthaman et al. Environmental Science & Technology, 2017, 51 (22), pp 13481–13486. DOI: 10.1021/acs.est.7b03464



We report a three-stage bench-scale column extraction process to selectively extract lithium chloride from geothermal brine. The goal of this research is to develop materials and processing technologies to improve the economics of lithium extraction and production from naturally occurring geothermal and other brines for energy storage applications.

A novel sorbent, lithium aluminum layered double hydroxide chloride (LDH), is synthesized and characterized with X-ray powder diffraction, scanning electron microscopy, inductively coupled plasma optical emission spectrometry (ICP-OES), and thermogravimetric analysis.

Each cycle of the column extraction process consists of three steps: (1) loading the sorbent with lithium chloride from brine; (2) intermediate washing to remove unwanted ions; (3) final washing for unloading the lithium chloride ions.

Our experimental analysis of eluate vs feed concentrations of Li and competing ions demonstrates that our optimized sorbents can achieve a recovery efficiency of ∼91% and possess excellent Li apparent selectivity of 47.8 compared to Na ions and 212 compared to K ions, respectively in the brine.

The present work demonstrates that LDH is an effective sorbent for selective extraction of lithium from brines, thus offering the possibility of effective application of lithium salts in lithium-ion batteries leading to a fundamental shift in the lithium supply chain.

South Africa: Five Promising Geothermal Regions Identified

Scientists urge the use of geothermal energy (Business Day)


A hidden, almost limitless supply of energy could be swirling around, directly beneath our feet. Local geologist Taufeeq Dhansay and a group of five fellow scientists from the Council of Geoscience and Nelson Mandela University believe that the government is overlooking significant volumes of buried Earth heat, which could be tapped to generate renewable energy.

Writing in the latest volume of the South African Journal of Science, Dhansay notes that SA does not have active volcanoes or evidence of recent volcanic activity. Yet he believes a recent heat-mapping study suggests there is still enough heat and warmth beneath the land that could be used to generate steam and electricity, making use of recent technological advances in the field of low-enthalpy geothermal energy harvesting.

Science & Technology: Geothermal Energy Technology Can Help in High Pressure and High Temperature Oil & Gas Exploration

Geothermal wells vs. HPHT in Oil & Gas (LinkedIn)

by Raymi Castilla, Exploration Geologist

HPHT is the term used in the oil industry to designate high pressure and high temperature fields/wells/reservoirs. A reservoir is considered HPHT if its temperature is above 150°C and its fluid pressure exceeds 69 MPa. 

Coming to the world of geothermal energy, I was curious how these two worlds match. How hot are wells considered HPHT in the oil industry compared to geothermal wells? How extreme are the conditions in which geothermal wells are drilled?

In contrast to Reverse Osmosis (RO), which utilizes mechanical energy to create a pressure gradient across a membrane to purify water, FO can be achieved by utilizing a draw solution to create an osmotic pressure gradient across the membrane to treat the water. Historically, FO systems have had limited utility because draw solutes have been difficult to separate from the treated water. Researchers at Idaho National Laboratory (INL) have developed a system for implementing FO using a switchable-polarity solvent (SPS) draw solution that can be easily extracted from the treated water stream and reused.

Dispatchable Geothermal Operations
The Geothermal Technologies Office solicits innovations that will enable geothermal energy to be more widely deployed as a dispatchable electricity source. These innovations can be in developing new hardware solutions, new systems of existing technologies, or new control algorithms and/or processes. Some potential areas of interest include: offsetting parasitic loads from normal plant operations during curtailment, improving lifetime reservoir performance, and integrating novel storage technology. The innovation could also take the form of developing an analysis tool that provides a valuation of operating current geothermal power plants in a flexible mode; however, any application proposing such an analysis tool must clearly show the ability to monetize their innovation in the commercialization plan.

United Kingdom: Work Begins on Scotland’s first Deep Geothermal Heating System

HALO ceremonial groundbreaking kickstarts work on £65m regeneration project (insider.co.uk)

A ceremonial groundbreaking has kickstarted work on the £65 million HALO urban regeneration project in Kilmarnock.

Parliamentary Under Secretary of State at the Scotland Office, Lord Duncan, was on site on Monday to witness the launch of the project.

The developers claim the Enterprise & Innovation Centre will “foster the next generation of entrepreneurs, with strong focus on innovation, digital skills, and cyber security”.

Scotland’s first deep geothermal heating system with a 2km deep well is to be drilled next year to enable water to be heated by the surrounding rocks, pumped back up again and then into properties in Kilmarnock.

Indonesia: A New Risk Mitigation Facility will Lead to Development of More than 1 GW of New Geothermal Capacity

Geothermal (The World Bank Group)

A new risk mitigation facility aims to encourage investment in large-scale geothermal energy in Indonesia.


With support from the World Bank and other partners, the government of Indonesia is planning a new Geothermal Risk Mitigation Facility. This would leverage several billion dollars in private sector funding, unlocking investments through risk mitigation for exploration and early production drilling. This would allow investors to prove sufficient resources to attract commercial finance for large-scale development. 

Over the next seven years it is expected that the facility will lead to the development of more than 1 GW of new geothermal capacity.

The Peppermill Reno is the only U.S. hotel heated 100% by on-site geothermal energy (News Release)

Geothermal Energy Powers The Peppermill Headlining the Resort Hotel’s Vast Green Initiatives


It took the Peppermill Resort Spa Casino $9.7 million and 4,400 feet of drilling, but the resort completed one of the most ambitious geothermal projects in the United States in 2010, tapping into a vast reservoir of natural geothermal activity more than three quarters of a mile underground to heat the property’s two million square feet of hotel, resort and casino operations

Several years after making that investment, the decision to invest in geothermal energy is paying off in spades for the Peppermill Resort Spa Casino. The property has saved  $2.2 million in natural gas bills they used to pay each year, and their carbon footprint has been drastically reduced by 12,000 metric tons of CO2 emissions per year, using the sustainable energy resource. 

The Peppermill’s pools, hot tubs, domestic water for showers, and mechanical systems, generate all of their heating energy from their geothermal operation 24 hours a day seven days a week. In addition to pumping the naturally heated water from the ground, the resort has also installed a reinjection well that returns the geothermal fluids back underground, to be reheated by the volcanic energy after it has heated the property.

Indonesia: 330-MW Sarulla Geothermal Power Plant to be Completed Next Year

Sarulla, One of the World’s Largest Geothermal Power Projects, Comes Alive with Private Finance (POWER magazine)

POWER magazine today officially announced winners of its 2017 Top Plants in the renewable power generation category. Among the five winners is Sarulla Geothermal Power Project in Indonesia.

The 330-MW Sarulla Geothermal Power Plant in Indonesia took decades to develop. Backed by a multinational financing effort along with support from the Indonesian government, the $1.6 billion project may be on track to achieve payback within nine years. 

Construction kicked off in earnest in May 2014, and this March, SIL, the first 110-MW unit of the power plant, commenced commercial operation. It is “performing well,” Ormat said. Successful testing was soon completed at the second unit, NIL 1, and the unit began supplying power on October 2, 2017. The third unit, NIL 2, is under construction, and Sarulla expects that the unit will commence operation in 2018.

Kenya: Electricity from Menengai Geothermal Power Project by March - GDC

First phase of Menengai power plant almost complete (Kenya Broadcasting Corporation)

Electricity generated from geothermal wells drilled by Geothermal Development Company (GDC) is expected to be injected to the national grid within the next four months.

GDC CEO Engineer Johnson Nchoe says the first phase of the new power plant in Menengai is in the last stages of development.

Three Independent Power Producers were contracted by GDC to put up power plants in Menengai to generate 105 MW.

The three comprising Sosian Energy, Quantum East Africa and Or Power were to each generate 35 MW. GDC says the first phase of this project is in the last stages of development and would be injected to the national grid by March next year.

Latin America: Second Call for GDF Funding for Geothermal Projects Now Open

2nd Call for EOI from Geothermal Development Facility for Latin America (News Release)

The Geothermal Development Facility for Latin America (GDF) has announced that the second call for Expressions of Interest (EOI) in grant funding for geothermal projects has begun.

The Pre-EOI sign-up phase is continuous and interested developers can complete the mandatory sign-up phase prior to completing the EOI.

However, once a Pre-EOI sign-up has been completed the developer is provided with the Developers’ and Procurement Manuals needed to understand how grant funding works and how to apply. As a point of reference, 100% of the developers that expressed an interest in the first call for EOI and then later submitted proposals were funded, totaling 22 million euros for four surface study grants and four confirmation drilling grants, in six countries.

Interested developers are encouraged to visit the GDF website, for further information.

United Kingdom: Opinion - Geothermal Power is an Option that Shouldn’t be Overlooked

Southampton's Geothermal Pursuit: A Success or Failure? (The Wessex Scene)

Spoiler! It's a success!

(Source: Suitcivil, Wikimedia Commons)
In 1987, drilling for the well started in the city centre. The well draws water from an aquifer 1800m under the surface, at a temperature of 76°C. The system is contained under a red corrugated building  next to WestQuay and IKEA. It provides 13 GWh of energy a year, and helps to provide the heating for several buildings, including WestQuay, the Civic Centre, and Royal South Hants Hospital. The amount of energy the system supplies is relatively low considering the amount of research and money put into developing it, but it is still considered as an efficient method of heating several buildings in the city centre around 30 years later!

With that in mind, as far as I can tell, Southampton’s very own geothermal project has been a success. To date, there has still been very little further research and development into the practical use of geothermal energy in the UK. There has been a small amount of research in Cornwall, and a similar system to Southampton’s is currently being developed for use in Stoke-on-Trent. Despite this, there’s evidence that geothermal has the potential to be able to supply a fairly significant portion of the UK’s energy and heating needs, and increased use and research would surely decrease the cost.

While there are several methods of sustainable energy sources that can be implemented in the UK to help replace the use of fossil fuels, it seems clear to me that perhaps geothermal power is an option that shouldn’t be overlooked.
