Geothermal Event! Four Exciting Fieldtrips from GRC Annual Meeting & Expo!

Fieldtrips from Geothermal Resources Council Annual Meeting  (News Release)

Spaces are filling up fast for these popular excursions from the GRC Annual Meeting & Expo in Palm Springs, California, USA.

In addition to the main event of the GRC Annual Meeting & Expo taking place September 15-18, 2019, there will be a grand total of four fieldtrips before and after the conference.

Just before the start of the conference two half-day trips will offer a chance to relax and enjoy the fantastic scenery and culture of the Palm Springs area. On Saturday, a three hour off-road ride in a Jeep will take you into the California Desert, along the San Andreas fault-zone through slot canyons and a natural palm oasis. On Sunday morning, a two-mile hike into the Palm Canyon will visit a special place for the Agua Caliente (Hot Water) Band of Cahuilla Indians among the trees in a beautiful palm oasis.

Just after the end of the GRC Annual Meeting & Expo on September 18, a two-day fieldtrip will take advantage of a rare opportunity to explore operations, volcanic geology and hydrothermal features of the Coso geothermal facility located at the China Lake Naval Air Warfare Station, California. This tour will also include a visit to GreenFire Energy’s experimental project demonstrating closed-loop geothermal power production technology using both water and supercritical CO2 as working fluids.

Also departing on Wednesday, September 18 another two-day fieldtrip will visit the Imperial Valley, home to the world renowned Salton Sea geothermal field. In addition to stops at the John L. Featherstone and Heber geothermal power plants, there will also be up-close observations of quaternary volcanoes, mud volcanoes, hot springs and an actively spreading mud pot! The valley has become a significant hot spot for renewable energy – with production from geothermal, solar, wind and biofuel – and possibly soon to be one of the most important regions for lithium mining.

More information on the fieldtrips, including more detailed itinerary and cost, can be found on the GRC Website at

United Kingdom: Research Opportunity in Low Enthalpy Geothermal Heat Recovery and Storage in Abandoned Flooded Coal Mines

Research into Microbially Enhanced Mine Water Geothermal Energy (Aberystwyth University)

Aberystwyth University, Wales, UK. Department of Geography & Earth Sciences - Application Deadline: 18th August 2019

(Courtesy Study in Wales)
Low enthalpy geothermal heat recovery and storage in abandoned flooded coal mines is an area of increasing interest as we move towards decarbonised heating and energy systems in both domestic and industrial settings. Exothermic heat generating reactions between water, aqueous and gaseous phases, and mineral surfaces are often mediated by and accelerated due to microbial activity in
surface mine waste, but little is known about subsurface processes. We are looking for a highly motivated student to investigate the microbiology of heat generating biogeochemical reactions in subsurface mine water settings.

The project aims to provide the first assessment of the role of microbiology on mine water geothermal energy production and will investigate these mechanisms in the South Wales Coalfield where there are a number of mine water geothermal schemes in development.

New Zealand: Geothermal Power Plant to Supply Heat for Wood Pellet Production

Contact Energy and Nature’s Flame reducing carbon emissions (News Release)

The Nature’s Flame plant in Taupo.
Contact Energy and Nature’s Flame have signed an agreement and broken ground to build a geothermal energy supply system that will provide process heat to Nature’s Flame’s wood pellet manufacturing plant in Taupō.

Nature’s Flame produces a carbon neutral wood pellet fuel alternative to coal. Wood fibre in the form or sawdust and shavings is obtained from sawmill operations in the central North Island; the fibre is dried, resized and then compacted to form a durable, low moisture, low ash, energy dense fuel which burns efficiently and cleanly.

“Contact will provide direct heat energy from our geothermal facilities to the Nature’s Flame plant which will be used to dry the wood fibre. The majority of the energy used to dry the wood will be derived from “used” geothermal fluid downstream of the Tenon Sawmill, which Contact has been providing with geothermal energy since 2007. This will optimise the efficiency of the production well for both companies,” says James Kilty, Chief Generation and Development Officer at Contact Energy.

Science & Technology: Geothermal Battery Claims to Generate Electric Power at less than 100 Degrees Celsius

Could the heat of the Earth’s crust become the ultimate energy source? (Tokyo Institute of Technology)

Researchers at Tokyo Institute of Technology and Sanoh Industrial created a very stable battery cell with the potential to directly turn heat into electricity, thus ultimately offering a method for making use of geothermal energy in a sustainable manner.

Generating electricity from geothermal energy requires devices that can somehow make use of the heat within the Earth's crust. Recently, a team of scientists at Tokyo Tech, led by Dr. Sachiko Matsushita, have made great progress in the understanding and development of sensitized thermal cells (STCs), a kind of battery that can generate electric power at 100℃ or less.

The team is very excited about their discovery because of its applicability, eco-friendliness, and potential for helping solve the global energy crisis. "There is no fear of radiation, no fear of expensive oil, no instability of power generation like when relying on the sun or the wind," remarks Matsushita. Further refinements to this type of battery will be the aim of future research, with the hope of one day solving humanity's energy needs without harming our planet.

USA, Utah: Valuable Data Made Available from the Frontier Observatory for Research in Geothermal Energy

3D Geophysical Modelling of Gravity Data at the Utah FORGE site (Innovate Geothermal)

By Christian Hardwick, Utah Geological Survey and Jeff Witter, Innovate Geothermal Ltd.

These resources describe the 3D geophysical inversion modeling of gravity data at the FORGE site near Milford, Utah. FORGE is the Frontier Observatory for Research in Geothermal Energy and the site in Utah has been selected by the U.S. Dept. of Energy for a 5-year R&D program to test technologies for the development of Engineered Geothermal Systems (EGS).

3D modelling of gravity data at the FORGE site is to help characterize the subsurface geologic framework. Specifically, modelling of gravity data in 3D, used in conjunction with rock density measurements and other subsurface geologic information can provide an independent test of an existing 3D geologic model (e.g. Witter et al., 2018). Such an exercise can be useful for reducing uncertainty in 3D geologic models (Witter et al, 2019).

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

A Quantitative Metric for the Design of Selective Supercritical CO2 Extraction of Lithium from Geothermal Brine (Wiley Online Library)

By Andrew W. Ruttinger, Cornell University, Ithaca NY, USA, et al. 

As demand grows for lithium, its recovery from geothermal brines provides an attractive alternative to slow mining. One promising extraction method uses crown ethers as extractants in supercritical carbon dioxide with cation exchangers to facilitate extraction from brine.

Binding free energy gives a suitable metric to describe extraction efficiency. Differences in the binding free energies of sodium and lithium to crown ethers determine the extraction selectivity. Fluorine groups are found to exert a positive influence to optimize extraction efficiency. Of the systems studied, F14C4 with TPFOS offers the most selective and efficient extraction system.

USA, Alaska: The Potential for Geothermal Energy in The Last Frontier

Geothermal development is heating up in Alaska (

Volcanoes along the Aleutian chain, hot springs in the interior and the Southeast. these are Alaska's three main geothermal resources. Lisa Murkowski has encouraged Alaskans to develop them. Gwen Holdmann, Director of the Alaska Center for Energy and Power (ACEP) says the main thing stopping development is the distance.

“At the end of the day, if you're looking at economic development of these resources, you need to have some sort of a load within a reasonable distance to make it worth developing or some way to attract industry to that location,” Holdmann says.

The ACEP has looked at ways to get around the distances between heat sources and population centers, and one solution they've found is agriculture.

“That's one of the things that we've worked with Pilgrim Hot Springs out in Western Alaska on is having local food production, and then exporting that food to other parts of the region," Holdmann says.

GeoGenCo, LLC of Las Vegas, Nevada, has completed their semi-final designs for their next generation True Geothermal 20 MW power plant in Imperial Valley, CA. GeoGenCo has a 15 MW Power Purchase Agreement with Imperial Irrigation District (IID) and expects to be providing power by June of 2020.

True Geothermal does not utilize any water in their power generation process. Rather than extracting the geothermal fluids, a high-performance heat exchanger is inserted into an existing (but non-performing) geothermal well where only heat is extracted from the geothermal formation, not from water, brine or steam. While a permit application for approximately six acre-feet of water has been filed, about one third of this water will be utilized for dust control and the other two thirds reserved for emergency fire-fighting purposes. Zero water will be utilized for the power generation process.

A GRC Fieldtrip will visit the Imperial Valley on September 18-19 from the GRC Annual Meeting & Expo in Palm Springs, California.

Science & Technology: Drilling Advisor has Ability to Operate in Geothermal Wells at Temperatures up to 250°C

Machine Learning Can Solve Drilling Problems When Physics-Based Models Fall Short (News Release)

A new research grant awarded under the United States Department of Energy's Small Business Innovation Research (SBIR) program aims to develop technologies that can harness these large data sets to help drillers make time-critical decisions. E-Spectrum Technologies, a leader in the development of technology-driven telemetry solutions for upstream energy markets, in partnership with the Harold Vance Department of Petroleum Engineering at Texas A&M University, has been awarded a Phase I grant to begin development and commercialization of a machine learning-based drilling optimization system.

The objective of the grant is to develop and commercialize a real-time computer advisory system to help drillers make more effective decisions and optimize the Rate of Penetration (ROP) achieved during drilling operations. The advisory system will use transformational digital technologies such as distributed processing and machine learning techniques to quickly identify ongoing or incipient vibration and loading patterns that can damage drill bits and slow the drilling process. Features of the drilling advisor include the ability to: operate in geothermal wells at temperatures up to 250°C; perform downhole bit dysfunction identification using machine learning; and transmit near-bit data using high-speed short-hop EM telemetry.
