PA31B-0348: Towards a Geocognition of Geothermal Energy: an Evolving Research Partnership in South West England

Hazel Gibson, (Plymouth University), Iain S Stewart (Plymouth University) and Peter Ledingham (Geothermal Engineering Ltd)

The development and deployment of novel geological technologies in industry often raise anxiety in the public sphere. New technologies are intrinsically unfamiliar, not only to the public, but also to other technical specialists in the field. This can focus conflict and uncertainty around issues that may not actually be problematic, or obscure other issues that may actually warrant closer inspection. An example of an emergent geo-technology that has received little attention in the public or general technical spheres is the introduction of Enhanced Geothermal Power in the UK. In early 2018, a project testing the viability of deep geothermal heat and power will begin in Cornwall, England, and is likely to face contested issues of public perception that have confronted other novel geological technologies, such as Carbon Capture and Storage and hydraulic fracturing.

To address concerns about how the UK public will conceptualise this new technology, the Cornish deep geothermal project has developed an innovative partnership between the industry partner operating the test drilling site and a geoscience cognition research partner.

Climate Change: Bill Gates' Clean-Energy Investment Fund Could Boost Geothermal Energy

4 signs of progress on climate change (Gates Notes)

By Bill Gates, Microsoft, Bill & Melinda Gates Foundation

I’m in Paris for the big meeting on climate change hosted by President Macron. Leaders from around the world are here to take stock of the progress the world is making on this urgent challenge.

This is a pivotal moment. We need to adapt to the climate change that is already affecting the planet, and develop new tools that will keep the problem from getting worse. Innovation is key to doing both. Scientific advances in crop science, for example, will help farmers deal with changing weather patterns. And energy research will make it possible to power modern life—the way we live, work, travel, and make things—without adding more greenhouse gases to the atmosphere.

The good news is that there’s a lot of progress to report on both fronts. Here’s an overview of the developments I’ll be highlighting in Paris.

Our $1 billion clean-energy investment fund is up and running. Breakthrough Energy Ventures has hired a staff of accomplished investors, company builders, scientists, and technologists. They have identified five areas that are especially promising but also underfunded. This is where we will focus our investments:

Geothermal power. There is a phenomenal amount of energy stored up as heat under the Earth’s surface—many times more than we could get from all the known coal and oil reserves in the world. Tapping this source involves pumping steam or hot water from underground to drive turbines.

Science & Technology: Using Supercritical Carbon Dioxide as a Working Fluid Could Boost Geothermal Power Production

Game-Changing Supercritical CO2 Cycles Are Closer to Commercialization (Power)

Supercritical carbon dioxide (sCO2) cycles—which are inching closer to commercial applications for waste heat recovery, concentrating solar power, nuclear, [geothermal] and fossil energy—offer higher thermal efficiencies and power density than conventional steam Rankine and Air Brayton cycles in use today for power generation. But to realize these potentially game-changing cycles, common challenges associated with turbomachinery must be overcome, experts from the Southwest Research Institute (SwRI) said as they presented a tutorial on December 12 at the Turbomachinery Symposium in Houston.

During their tutorial, which provided an overview of ongoing research on sCO2 power cycles and associated turbomachinery, the experts noted that SwRI is designing and should soon begin building a 10-MW grid-connected pilot project at the organization’s campus in San Antonio, Texas, that will use sCO2 Brayton power cycles.

Raft River Geothermal Power Plant. Photo taken by Ian Crawford on GRC Fieldtrip, 2015.
U.S. Geothermal Inc. announced today that it has reached an agreement to acquire its partner's remaining ownership interest in Raft River Energy I LLC from Goldman Sachs. The purchase is scheduled to close on January 2, 2018 and the price consists of a one-time, $350,000 cash payment from U.S. Geothermal to Goldman Sachs. The Company will then own 100 percent of the project.

Raft River Energy I is located in Southern Idaho, near the town of Malta, and achieved commercial operation on April 3, 2008.  The Raft River facility is a single, 18-megawatt (gross) module, with a design output of 13 megawatts (net) annual average based on a specific flow and temperature of geothermal brine. The PPA for the project was signed on September 24, 2007 with the Idaho Power Company and allows for the sale of up to 13 megawatts of electricity on an annual average basis over a 25-year term.  Renewable Energy Credits are sold under a separate contract.  In 2018, the PPA energy price, plus the value of the renewable energy credit will be $74.32 per megawatt-hour.

The company is in a continuing process to increase generation at Raft River through modifications at the existing facility. The addition of production well RRG-5 along with upgrades to the injection system in 2017 increased the average generation from the Raft River plant by approximately 1.6 net megawatts. Due to the positive response from the wellfield, which showed a minimal decrease in fluid levels, a study to increase the capacity of production pump RRG-4 in 2018 will be analyzed.

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.

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: 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 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.

The case studies are presented here to illustrate the application of the geothermal energy specifications for the uniform use of UNFC in different contexts. These application examples from different countries provide a range of scenarios in the classification of geothermal resources in a manner consistent with the classification of other energy resources.

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.

USA: Demand Flagging for GE’s Power-Generation Equipment

GE to Cut 12,000 Jobs in Its Power Business (Bloomberg)

General Electric Co. plans to cut 12,000 jobs in its power business as the company’s new leaders look to slash costs and stabilize the beleaguered manufacturer.

The reductions, accounting for about 18 percent of GE Power’s workforce, include both professional and production employees, the company said Thursday in a statement. The world’s largest maker of gas turbines said the unit needs to become leaner as customers turn away from fossil fuel-based energy sources.

Demand is flagging for GE’s power-generation equipment because of overcapacity, lower utilization, fewer outages and the growth in renewable energy, said Stifel Financial Corp. analyst Robert McCarthy.

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.

Spain: Government of Canary Islands Needs to Step Up Support for Geothermal Exploration

El Gobierno descarta la geotermia para producir electricidad - The Government disregards geothermal energy for producing electricity (Canarias7)

El Gobierno de Canarias «ni siquiera valora presupuestariamente» la exploración geotérmica de alta entalpía, algo por lo que los cabildos de Gran Canaria, La Palma y Tenerife si apuestan y están dando los primeros pasos, con financiación propia, y de la mano del Involcan. De momento, la exploración es en superficie, previos a hacerlos en profundidad.

(From Google Translation) The Government of the Canary Islands "does not even value fiscally prudent" exploration for high enthalpy geothermal resources, something which the councils of Gran Canaria, La Palma and Tenerife have invested in and are taking the first steps, with their own funding, with help from  Involcan. At the moment, exploration is on the surface, before continuing at depth.
