California Court Orders New Environmental Review for Imperial County Geothermal Lithium Project

California Appeals Court Orders New Environmental Review for Imperial County Geothermal–Lithium Project Image: California Salton Lake Sea Hell’s Kitchen geothermal and lithium extraction plan sent back for deeper water, air-quality and mitigation analysis under CEQA A California appeals court has ordered Imperial County to conduct a more rigorous environmental review of the proposed Hell’s Kitchen geothermal power plant and lithium extraction project near the Salton Sea. The Fourth District Court of Appeal found that the county’s original environmental impact report (EIR) did not adequately address long-term water availability, enforceable mitigation measures for water shortages, or potential air-quality impacts tied to the receding Salton Sea. The ruling partially reverses a lower court decision and remands the case to Imperial County Superior Court, requiring the county and project developer Controlled Thermal Resources to address the identified deficiencies before the project can m...

Billionaire Families Bet on Advanced Geothermal Energy Investments

Billionaire Geothermal Families Bet on Geothermal Billionaire families and private investment offices are placing increasingly large bets on geothermal energy, especially on technologies designed to make the resource available in more locations. Their investments are helping finance enhanced geothermal systems, advanced drilling, closed-loop designs, and other approaches that could transform geothermal from a regionally concentrated power source into a globally scalable clean-energy industry. The investment surge reflects a broader change in the energy market. Electricity demand is rising because of artificial intelligence, data centers, industrial electrification, electric vehicles, and the expansion of digital infrastructure. At the same time, utilities and large corporations need power that is reliable around the clock. Solar and wind remain essential to the clean-energy transition, but their output varies with weather and time of day. Geothermal could complement these technologies ...

LCOE Compared: Eavor Technologies vs.  Fervo Energy   Two Bets on Next-Generation Geothermal An Alphaxioms Geothermal Insights Analysis | May 2026 Image:  Eavor and Fervo Drilling Rigs well poised in their respective well pads , drill baby , baby what a time to be a live Introduction: Why the Cost Question Matters Now The global geothermal sector is in the middle of a pivotal moment. After decades of stagnation largely confined to volcanic hotspots, two fundamentally different technological approaches are racing to prove that geothermal energy can be deployed broadly, cheaply, and at scale. Eavor Technologies , the Calgary-based advanced geothermal systems (AGS) company, and Fervo Energy , the Houston-based enhanced geothermal systems (EGS) pioneer, represent the sharpest divergence in next-generation geothermal strategy today. Each company is backed by hundreds of millions of dollars in private capital, each has reached key commercial milestones, and each is advancing ...

KenGen Risks Losing Olkaria Geothermal Wells Over Licence Error

KenGen Risks Losing Olkaria Wells Over 18-Year Licence Blunder Kenya Electricity Generating Company (KenGen) faces a serious legal and operational risk at Olkaria after an error in the coordinates of its geothermal licence left part of the company’s wells, steam infrastructure and other assets outside its legally recognised area. The licensing mistake, made nearly two decades ago, remains unresolved despite the Ministry of Energy and Petroleum acknowledging the problem in 2017.  The dispute has raised questions about the security of KenGen’s investments, the government’s management of geothermal resources and the potential consequences for Kenya’s electricity supply. Olkaria is the country’s most important geothermal centre and accounts for the overwhelming majority of Kenya’s installed geothermal generation capacity.  Licence Error Exposes Strategic Assets The problem dates back to September 19, 2008, when the Ministry of Energy and Petroleum issued KenGen a licence covering ...

DOE Backs $14 Million Utica Shale Geothermal Energy Demonstration Project

Utica Shale Geothermal Breakthrough Redefines America’s Clean Energy Future By: Robert Buluma The United States is preparing to test one of the most ambitious geothermal energy demonstrations ever attempted in the eastern part of the country. In a move that could fundamentally reshape how abandoned and active oil and gas infrastructure is utilized, the US Department of Energy (DOE) has announced a $14 million Enhanced Geothermal Systems (EGS) demonstration project targeting the prolific Utica Shale formation in Pennsylvania. At first glance, the announcement may appear like another government-backed energy research initiative. But beneath the surface lies something far more transformative: the possible birth of a new geothermal frontier built directly on the foundations of America’s shale revolution. For decades, geothermal power in the United States has largely been associated with the western states—California, Nevada, Utah, and parts of Idaho—where naturally occurring geothermal...

Djibouti Pays KenGen: $1M Offer on a Five-Year Geothermal Drilling Debt

Djibouti Pays KenGen: A $1 Million Offer on a Five-Year-Old Geothermal Drilling Debt Djibouti has finally moved to pay part of what it owes Kenya Electricity Generating Company (KenGen) for drilling work done near Lake Assal. The amount is small next to KenGen's balance sheet. What it says about selling geothermal drilling services across Africa matters a lot more. KenGen's latest annual report says Djibouti's state geothermal agency, the Office Djiboutien de Développement de l'Énergie Géothermique (ODDEG), has offered a first instalment of about $1 million (Sh129 million) against outstanding invoices of $2.13 million (Sh276.03 million), according to Business Daily. "ODDEG has acknowledged the debt and has proposed an initial payment of $1 million as the first instalment towards settlement," KenGen said in the report. KenGen is Kenya's largest power producer, with about 54% of the market. The Kenyan government owns 70% of the company and the public holds t...
