USA, California: Chance to Visit a Mysterious Moving Geothermal Mud Pot

A Moving Mystery (ACSE)

A GRC fieldtrip will visit the Wister mud pots mentioned in the article

The time series from Google Earth shows the appearance of W9 and the first detection of the moving mud spring (in 2016) as a southwestern elongation in W9. (images adapted from Google Earth by David K. Lynch)
Along the southeastern edge of California's Salton Sea, there are several areas that contain geothermal mud pots and mud volcanoes—geological features that may change shape, but never location.

In 2016, a large, muddy CO2 -driven mud spring in Imperial County, California, developed—and in a completely unexpected way, began moving southwest. By early 2018, the mud spring threatened local infrastructure, including a railroad, a pipeline, and a state highway.

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.

Science & Technology: Shape Memory Polymers Activated by Geothermal Temperatures to Prevent Loss of Fluid in Fractured Rocks

OU Research Team Developing New Methodology and Smart Wellbore Materials for Geothermal Drilling (University of Oklahoma)

Saeed Salehi, project principal investigator and
professor of petroleum and geological engineering,
Mewbourne College of Earth and Energy.
A University of Oklahoma (OU) research team is developing smart lost circulation materials that use shape memory polymers activated by geothermal temperatures to prevent the loss of fluid in fractured rocks near the wellbore. These materials expand within the fractures to reduce non-drilling time and strengthen the wellbore in high-temperature drilling operations.

The U.S. Department of Energy’s Geothermal Technologies Office funded the early-stage research with a $1.79 million grant. In addition, the project has more than $0.5 million cost share from various entities.

“The cost of drilling a geothermal well is prohibitive without new technologies to address the challenge of drilling the type of rock found in a geothermal well,” said Saeed Salehi, project principal investigator and professor of petroleum and geological engineering, Mewbourne College of Earth and Energy. “The shape polymers under development for this project are novel expandable and programmable polymers that activate when drilling a high-temperature geothermal drilling operations.”

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

Geothermal development is heating up in Alaska (KTUU.com)

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.

GRC Fieldtrip  2013.
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.

St Vincent and the Grenadines: Geothermal Project Reaches 250 Degree Celsius Resource at 2500 Meters

SVG’s geothermal source good, but “a little deeper” than expected (Searchlight)

It has been determined that at 2,500 metres below ground that St Vincent and the Grenadines has suitable temperature and permeability to generate geothermal energy.

This report comes two months after exploratory drilling began here at the foot of La Soufriere.

Prime Minister Dr Ralph Gonsalves said on radio yesterday, while reading from a report he received this week, that at a depth of 2500 meters, the temperature was more than 250 degrees Celsius. He described this as a “great temperature” and said in the geothermal source itself, they have met the first permeability of the soil which was measured at 1.5 litres per second.

He said that officials expected the geothermal source to be deep, but it is a little deeper than expected as they intend to go down to 2700 metres into the earth.

And he said drilling will continue in order to benefit from the greater permeability.

Geothermal Event! Program Updated

GRC Annual Meeting & Expo

Geothermal: Green Energy for the Long Run

15-18 September, Palm Springs Convention Center, Palm Springs, California, USA



United Kingdom: Drilling Rig Being Demobilized at United Downs Deep Geothermal Power Project

Update from the United Downs Deep Geothermal Power Project (Geothermal Engineering Ltd)

We finished drilling our injection well, UD-2, at the end of June and have now started the process of demobilising the drilling rig. It is returning to Helsinki in Finland to carry out further geothermal drilling on the project where it was working before it came to us.

During this week most of the ancillary equipment, the drill pipe and some of the rig components will leave. Next week the mast will come down and the remaining rig components will be broken down and removed from site.

The transport process is the same as when we mobilised the rig last October, please see the map above for the full route from the United Downs industrial estate to the A30. There will be about 80 truckloads leaving the site over the next two weeks using the route agreed with the Local Planning Authority as part of the planning consent for the site; through Crofthandy, Vicarage Hill and Scorrier to the A30 at Avers roundabout. This route has been agreed on the basis of minimising impact and traffic disruption to the local community.

Once again, thanks to the kind permission of the United Downs Raceway operators, we will use the raceway car park as a marshalling area for the trucks to minimise congestion on the industrial estate and nearby roads.

Everything should be off the site by about 20th July.

Europe: Combined Heat, Power and Metal Extraction Consortium Roadmap to 2030 and Beyond

Roadmap for 2030 and 2050 (CHPM2030 project consortium)

CHPM2030 Deliverable D6.3


The Combined Heat, Power and Metal (CHPM) extraction 2030 project roadmap for 2030 and 2050 has been developed using the synergetic combination of three future-oriented layers of studies:
  1. The “CHPM component roadmap” study provides a direct follow-up of the current technological components (e.g. metal mobilization/recovery), by describing the state-of-the-art, immediate research plan (2025), pilot research plan (2030), and long term objectives (2050); 
  2. The “Preparation for future pilots” study investigates the pathway to pilot implementation by 2030, by providing a detailed description of the 5 areas in Europe (Cornwall, Iberian Pyrite Belt, Beius Basin/Bihor Mountains, Kristineberg and Nautanen) for CHPM potential with recommendation for future exploration, stakeholder engagement and funding opportunities. 
  3. The “Overall concept of CHPM” study investigates the feasibility of combining geothermal energy with mineral extraction with the use of foresight tools such as Horizon Scanning, Delphi survey and Expert workshops. 
Targets and actions have been identified related to exploration, development, operation, and market, all related to CHPM technology. Using the synergetic combination of these three layers, a timeline has been constructed, including milestones, objectives and target to be achieved in order to arrive to pilots by 2030 and full-scale application by 2050.

Southern Africa: Opportunities for Geothermal Energy for SADC Countries

SADC countries must consider Kenya’s geo-thermal energy concept (The Southern Times)

There is a need for the region to accelerate the development of its renewable energy options. An alternative and reliable form of energy which can be recommend for consideration could be geothermal generated power.

The Southern African Development Community (SADC) has been making efforts in developing wind and solar power plants, but wind and solar energy are also extremely dependent on weather conditions, whereas geothermal power can be accessed through hot springs and is readily available 365 days per year. Little to no exploration studies regarding this renewable form of power have been conducted in most countries that makes the SADC region. Although estimates have been made as to its generating capacity, not much is known about its true potential. Zimbabwe for instance has several thermal hot springs situated in Binga and Manicaland.

There are over 30 known sites in Zimbabwe where hot water gushes from the ground. The heat generated from the hot springs can be used to generate electricity through geothermal power plants.

It is time to consider advanced research and data acquisition of geothermal power and development, so that we may decipher its capabilities and possible negative impacts.

El Salvador: Turboden Supplies 8 MW ORC Turbine to Berlin Geothermal Project

The 380th Turboden ORC Plant is a Geothermal One for El Salvador

Turboden integrates the existing Berlin flash geothermal complex with its ORC binary plant designed to produce up to 8 MWe *

Turboden has signed an agreement with La Geo for the supply of an ORC geothermal power plant in El Salvador, at Berlín Geothermal Field. The plant is designed to produce up to 8 MWe.

During 2003-2007, a third single flash condensing unit went on line (for about 44 MWe) along with a pumping station to reinject the hot brine. In order to improve the whole thermal efficiency of the complex, a first binary unit was commissioned in 2007 as bottoming stage.

Turboden ORC unit will operate with the hot separated brine from a group of wells, without requiring extra drilling, recovering heat at 172°C before reinjection. Reinjection temperature has been selected in order to avoid super saturation of silica in the geothermal brine. This new bottoming plant will further contribute to the country’s renewable base-load generation, increasing the savings of CO2 emissions.

USA, California: Opportunity for Geothermal Energy Sector to Engage With a New Generation of Power Procurers

California's renewable energy growth (Utility Dive)

Community Choice Aggregators say they will use resource diversity, distributed energy resources and load management to lead California beyond its 2030 renewables goals.


California's Senate Bill (SB) 100 initiated a new phase in the state's nation-leading climate fight, with new goals for 60% renewables by 2030 in the power sector and zero-emissions economy-wide by 2045.

A mostly new group of load serving entities (LSEs), primarily community choice aggregators (CCAs) and municipal utilities, will be charged with meeting these goals.

"They will procure because they need about four GWs of long-term renewable contracts by the end of 2023 to meet their RPS obligations," said Large-scale Solar Association (LSA) Executive Director Shannon Eddy.
