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.

India: 90% Probability that the Puga Geothermal Field Could Sustain a 20 MW Power Plant

Geothermal energy could light up rural Ladakh (India Climate Dialogue)


Puga Valley in the Ladakh region of Jammu & Kashmir is one of the areas showing significant potential for geothermal energy. Puga lies in the south-eastern part of Ladakh and forms a part of the Himalayan geothermal belt. This zone shows evidence of geothermal activity in the form of hot springs, mud pools, sulphur and borax deposits.

“Since Ladakh lies in the confluence of two continental plates, geothermal (energy) can be found easily here. The potential is strong as we have good source of water due to rivers and hot springs,” Jigmet Takpa, Director, Ladakh Renewable Energy Development Agency (LREDA), told indiaclimatedialogue.net. “More survey is needed to test the depth in the valley. We need to reach a minimum of 2 km depth to see how temperature changes, if it is earth’s heat or magma, or if lava is coming out.” To find the real potential in Puga Valley, there is a need for in-depth information on the reservoirs.

According to a paper titled Assessment of subsurface temperature distribution from the gauged wells of Puga Valley, Ladakh published in the Geothermal Energy journal in 2017, it is estimated that over 5,000 MWh of geothermal energy is available at Puga at current depths, which could be used for heating, greenhouse cultivation and electricity generation. Studies have indicated that there is a 90% probability that the Puga field could sustain a 20 MW power plant at the current shallow depth of drilling. A 20 MW geothermal plant at Puga could save three million litres of diesel burnt annually in the region at a cost of approximately USD 2 million.

USA, Washington D.C.: Discussion of Enhancing Geothermal Production on Federal Lands Act

Legislative Hearing on Geothermal Exploration, 3 Other Bills  (Committee on Natural Resources - United States House of Representatives)


Thursday, November 30, 2017 2:30 PM, Washington D.C., USA
  • Discussion Draft of H.R. (Rep. Raúl Labrador), To amend the Geothermal Steam Act of 1970 to promote timely exploration for geothermal resources under geothermal leases, and for other purposes. “Enhancing Geothermal Production on Federal Lands Act” Hearing Memo

Sponsored by Congressman Raúl Labrador, the “Enhancing Geothermal Production on Federal Lands Act” seeks to incentivize new production of geothermal energy resources on federal lands, and support increased production on lands already leased for that purpose. 

To achieve these goals, this bill amends the Geothermal Steam Act of 1970 to create a Categorical Exclusion (CX) under the National Environmental Policy Act of 1969 (NEPA) for qualifying geothermal exploration test projects, permit coproduction of geothermal resources on land leased for oil and gas, and allow for noncompetitive leasing on federal lands adjacent to other lands currently leased for geothermal energy production. 

USA, Colorado: Pagosa Springs Geothermal Greenhouse Project Expands

Geothermal Greenhouse Awarded Colorado Water Plan Grant (Pagosa Daily Post)


The Geothermal Greenhouse Partnership (GGP) will begin construction of two more growing dome greenhouses — the Community Garden Dome and the Innovation Dome — in spring 2018. These two domes will be installed next to the existing Education Dome in Pagosa Springs’ Centennial Park on a parcel leased from the Town of Pagosa Springs.

The Colorado Water Plan (CWP) Engagement and Innovation Fund granted Geothermal Greenhouse Partnership $174,500 for the construction of the nonprofit organization’s second and third growing domes. The Colorado Water Conservation Board approved the CWP grant earlier in November. These funds, coupled with a $34,000 matching grant from Colorado Garden Foundation awarded last February, allow the GGP to fulfill its agreement to build three geothermal greenhouses.

The owners of GEK have previously had a discrepancy in how to best develop the geothermal power plant. Now, with the solution proposed by Climeon, all parties have an aligned view on how to develop the geothermal asset. The parties are currently negotiating financing solutions. If financing is secured and the parties have agreed upon a final purchase order for a Heat Power system, a contract will be signed.

Science & Technology: New Method to Extract Lithium and Gold from Brine at Geothermal Power Plants

MGX Minerals to target geothermal market for extraction of lithium and gold (News Release)

MGX Minerals Inc. of Vancouver, Canada, continues to explore the latest technologies in mineral extraction, saying its partner PurLucid, also based in Canada,  has developed a high temperature filtration method to purify geothermal brines - similar to oil field brines.

Geothermal brines, like those from oilfields, contain concentrated amounts of metals and dissolved salts, including lithium and gold. A barrier in the industry has been the need to reduce brine temperatures so filtration can occur - a barrier known as scaling that severely reduces flow and heat transfer of geothermal heat exchangers.

But Purlucid and MGX have now developed a proprietary, low energy design process that removes these scale-forming ions and dissolved salts while not requiring a reduction in brine temperatures for filtration to occur, said the company. Notably,  the process uses PurLucid's existing patented and exclusively licensed replaceable membrane skin layers (RSL) filtration system.

Similar to MGX's existing wastewater treatment and rapid petrolithium recovery units, MGX and PurLucid are now undertaking studies to build treatment systems capable of being integrated into existing geothermal infrastructure or incorporated as standalone systems for mineral and metals extraction.

USA, South Dakota: Geothermal Energy Research in an Abandoned Gold Mine

A Group of Scientists Walk Into a Mine ...

…to conduct cutting-edge renewable energy research on behalf of the Geothermal Technologies Office.


The Homestake Gold Mine in Lead, South Dakota, was once the largest and deepest gold mine in all of North America. It produced approximately 41 million ounces of gold during 126 years of operation. In 2002, the mine was shuttered when the gold veins vanished. Then, after pumping and maintenance costs increased, the Barrick Gold Corporation let the mine slowly fill with water.

Beginning this year, Lawrence Berkeley National Laboratory (LBNL) is leading a new geothermal research project at the mine, dubbed “Collab.”

Lawrence Berkeley National Lab is partnering with seven other DOE national labs and six universities to develop field experiments focused on understanding and modeling rock fractures, an essential element of “enhanced geothermal systems.” With this research, they could help unlock 100-plus gigawatts of EGS potential.

Science & Technology: Making ORC Geothermal Power Systems More Effecient

Music to Power Producers' Ears: HARP Provides a New Spin on Old Technology (PNNL)

Harmonic Adsorption Recuperative Power System turns heat into seriously efficient power

(Video 1:01 Minutes)

Sponsored by the DOE’s Geothermal Technologies Office, Pacific Northwest National Laboratory (PNNL) in Washington State, USA “rewrote the book” on the operation of Organic Rankine cycle (ORC) systems in an effort to make a transformational advance in the technology and its use within the geothermal industry. The PNNL-developed system—the Harmonic Adsorption Recuperative Power System (HARP)—uses a novel approach that eliminates the need for the evaporator, high pressure pump, and condenser in ORC systems.

Conventional ORC systems work by transferring heat to a working fluid until it vaporizes at a constant pressure. The high-pressure vapor is passed through a turbine, or other engine, that produces electricity. The vapor is then condensed back to a liquid and recycled using an electric powered pump. The HARP cycle scraps all those components and substitutes a patented multi-bed heat engine architecture and a specially formulated metal organic framework (MOF) sorbent to drive the engine.

Canada: Valemount Geothermal Project Waiting on Drilling Permit

Geothermal energy optimism heats up (Business in Vancouver)

Small geothermal demonstration project in Valemount enjoys all party support.

Surface exploration work for the geothermal site near Valemount is complete, and the project now awaits a drilling permit. 
Regardless of whether the BC NDP government decides to finish or cancel Site C dam, proponents of geothermal power are now hopeful that at least one small demonstration project may move forward. They hope that it will prove that geothermal energy can be developed in B.C. for a reasonable price, despite the costly failures of the past.

The project is near Valemount, B.C., which lies just outside of Mount Robson Provincial Park. It was recently the subject of “raging agreement” in the legislature, where all three parties voiced support for the project.

The one holdup has been a drilling permit, which is still awaiting cabinet approval. Once that is granted, Borealis GeoPower would drill a test well to determine the energy potential of a hot aquifer at Canoe Reach near Valemount.

The first phase of a three-phase project would be hot springs that the Valemount Geothermal Society wants to develop. The second phase would be a small power plant that would produce one megawatt (MW) of electricity – nearly enough to supply the town of Valemount (population 1,100). The third phase would be a larger, 15-MW power plant.

Science & Technology: Study Reveals Sources of Geothermal Energy in Greenland

Predicting the geothermal heat flux in Greenland: a Machine Learning approach (Geophysical Research Letters)

By Soroush Rezvanbehbahani et al
Geophysical Research Letters, Volume 44, Issue 21,
DOI: 10.1002/2017GL075661


Geothermal heat flux (GHF) is a crucial boundary condition for making accurate predictions of ice sheet mass loss, yet it is poorly known in Greenland due to inaccessibility of the bedrock. Here we use a machine learning algorithm on a large collection of relevant geologic features and global GHF measurements, and produce a GHF map in Greenland which we argue is within ∼15% accuracy.

The main features of our predicted GHF map include a large region with high GHF in central-north Greenland surrounding the NorthGRIP ice core site, and hotspots in the Jakobshavn Isbræ catchment, upstream of Petermann Gletscher, and near the terminus of Nioghalvfjerdsfjorden glacier.

Science & Technology: Abandoned Coal Mines - a Potential Source of Geothermal Heat

We could use old coal mines to decarbonise heat – here’s how (The Conversation)

There is a delightful irony that the legacy of the dirtiest of fuels, coal, now has the potential to deliver a low carbon energy future.

(Wikipedia Commons)
Abandoned coal mines seem incredibly promising due to their networks of flooded galleries and shafts lying at depths of up to several hundred metres below the surface. One can be almost certain that the water flow necessary for deep geothermal wells will be found in these flooded underground voids. The risk of not finding flowing water underground can inhibit deep geothermal developments elsewhere.

The volume of coal extracted compares to an equivalent void volume underground. On this basis (once allowing for subsidence), we estimate that the abandoned mines of the UK contain around two billion cubic metres of water at temperatures which are constantly around 12-16°C, and in some instances higher still. If heat corresponding to a 4°C temperature drop was removed from this volume, around 38,500TJ of heat could be liberated. This conservative estimate could provide enough heat for around 650,000 homes nationally.

Turkey is an emerging superstar in the geothermal energy field thanks to a combination of its underground resources and a stable tariff regime. Other countries in Southeast Europe can’t hope to emulate the kind of investment seen in Turkey, the site of some of the world’s largest geothermal power plants, but they too are increasingly harnessing underground energy to provide cheap and eco-friendly local heating and energy.

A utility-scale geothermal power plant may be beyond the reach of most of the Balkan countries northwest of Turkey, but this hasn’t stopped them looking to tap their more modest geothermal resources for example for district heating, or to power greenhouses. And the region has long used thermal waters for spas, from the Ottoman era Turkish baths in Budapest to Europe’s largest waterpark, the brand new Therme in the outskirts of Bucharest.

Eight Los Alamos National Laboratory (LANL) technologies won R&D 100 Awards last week at R&D Magazine’s annual ceremony in Orlando, Florida. These “Oscars of Invention” honor the latest and best innovations of the past year.

LANL is a United States Department of Energy national laboratory based in New Mexico. Two of the awards are for geothermal energy applications:

Discrete Fracture Network Modeling Suite (dfnWorks) is a computational suite that simulates and predicts the flow and transport of fluids through underground fractured rock. It covers length scales that range from millimeters to kilometers, can run on computers as small as a laptop and as large as a supercomputer and requires minimal effort to create representative models. Applications for dfnWorks include helping catch rogue nations performing underground nuclear tests and maximizing the extraction of natural gas, oil and geothermal wells while minimizing environmental impacts.

High-Temperature Electric Submersible Pump Motor (HT-ESP) is rugged and reliable, offering improved thermal performance compared to conventional submersible pumps used in deep underground and extremely hot environments. Whether electric submersible pump motors are used in drilling deeper for oil and gas reservoirs or tapping into geothermal resources of energy, they must operate in harsh, extremely hot environments. Current pump motors overheat and must be replaced often. To solve this, the Los Alamos and the Chevron Energy Technology Company research team developed two technologies for HT-ESP to lower the internal operating temperature of the motor.

Science & Technology: Steel is Playing Indispensable Role in Renewable Energy Technologies

#lovesteel: Steel and Renewables (worldsteel)

By 2030 the world must reduce its CO2 emissions by 12-14 gigatonnes if it is to meet the target of keeping temperature rises below 2 degrees centigrade. Steel is playing an indispensable role in renewable energy technologies, helping to harness the power of the wind, the waves, the sun and the earth itself for the transition to a more sustainable energy mix.

United Kingdom: Research on Using Flooded Abandoned Mine Workings as a Geothermal Heat Source

Modelling Geothermal Heat Extraction from Abandoned Mine Workings and Associated Ground Stability Issues (Quintessa)

Mines across the Scottish Central Coalfield

Quintessa are supporting an exciting new PhD research project at the University of Edinburgh, continuing our close cooperation with Chris McDermott. Fiona Todd will be investigating the practicality of using flooded, abandoned mine workings as a geothermal heat source – potentially a key supply of low-carbon energy for those cities with a long-standing mining heritage.

The large area of typical mine workings and the elevated temperature at depth, make such underground voids a potentially very efficient means of accessing the heat being generated at depth in the Earth. Her focus will be on understanding the stability of the mined caverns, looking at the coupled Thermal-Hydraulic-Mechanical (THM) behaviour of the mine supports and the potential ground-surface impact. A key source of data will be from the Clyde Gateway (Glasgow), where a complex geometry of mines exist at a range of depths; Fiona will be working closely with the BGS and the Coal Authority to take full advantage of the available data.

Switzerland: Geothermal District Heating Project Starts in Geneva

Major geothermal project starts in Geneva (WRS)

A large borehole is being drilled in Satigny. It will reach 650 meters down. Geologists believe the water temperature at that depth will be around 25 to 30 degrees.

There will be a further six bores drilled in the next three years. The canton hopes the new power source will cut the use of heating oil by 53 percent.

But the holes go nowhere near the depth of the ones in Basel and Sankt Gallen which were blamed for creating small earthquakes. Those were down to a depth of around 5 km.

USA, Nevada: State Gets Behind Fallon FORGE Project

Governor's office pushes for federal geothermal research lab (The Nevada Independent)


Nevada State officials pledged $1 million this week to a years-long effort to land a national geothermal laboratory near Fallon. The Fallon site is one of two locations competing to serve as the main hub for the Department of Energy’s geothermal research. The other possible site is in Utah.

The federal agency is expected to pick a site next year. Researchers have been developing the Fallon project since November 2014, when a proposal was first submitted to the Department of Energy. In late 2016, it was selected as one of two possible sites for the Frontier Observatory for Research in Geothermal Energy (FORGE) lab. Since then, a team of researchers from organizations and national labs, has been conducting environmental reviews, drilling test holes and working on getting federal land permits.

For utilities that buy geothermal, this could change the economic equation.

“As you go to higher penetrations of renewable energy displacing thermal plants, geothermal has a significant value. And that is you can dispatch it,” NV Energy CEO Paul Caudill said in a recent interview with The Nevada Independent. “We can use geothermal plants at night when we can’t use a solar facility. I think there is a significant value there. And as you start pushing to increase [solar] penetration on the grid, geothermal is going to become more valued.”

USA, California: Community Choice Aggregation Could Offer Opportunities for Geothermal Energy in San Diego

Community Choice Energy clears hurdle in San Diego (San Diego Reader)

San Diego is close to the large geothermal energy
resources at the Salton Sea
San Diego on Thursday took another step in the lengthy process of establishing a community choice aggregation market for city residents and businesses, as the city's Sustainable Energy Advisory Board voted to send a feasibility study completed in July to the city council with a recommendation to move forward on its action points.

Under community choice, a city government or nonprofit takes over the role of buying and selling power, while the local utility maintains control and maintenance responsibility for transmission of that power, collecting a fee for doing so. Residents who wish to opt out of the program and continue buying power directly from the utility have an option to do so. Advocates say that such a choice puts downward pressure on electric costs while increasing the amount of renewable power on the grid at a rate faster than utilities are currently ramping up reliance on solar, wind, and geothermal generation.
