Újbuda Geothermal Energy Exploration Approval Boosts Sustainable Heating Potential

Újbuda Gets Approval to Explore Its Geothermal Energy Potential Budapest’s Újbuda district has received approval to examine whether geothermal energy can contribute to its future heating and energy needs. The decision places one of the capital’s most densely populated districts at the centre of Hungary’s broader effort to make better use of its underground thermal resources. The approval does not mean that a geothermal power plant or district-heating system will be built immediately. Instead, it allows the district and its partners to investigate the geological conditions, technical feasibility, environmental implications and financial requirements of using heat stored beneath the city. The project could eventually support cleaner heating, reduce dependence on imported natural gas and strengthen Budapest’s energy resilience. Its success, however, will depend on careful geological research, responsible water management, transparent public consultation and a realistic financing model. Wh...

Turkey Geothermal Sector Seeks “Super Permit” Reform to Fast-Track 4,500 MW Expansion

Turkey’s Geothermal Sector Wants a Faster Path to Growth By: Robert Buluma Image: A Turkish Geothermal Power Plant  Turkey’s geothermal industry is asking for a simpler permitting system that could speed up investment, cut delays, and help the country reach its 2035 energy targets more efficiently. With installed geothermal power already at 1,800 MW, the sector says it is ready to scale to 4,500 MW and beyond if approval processes are streamlined without weakening environmental safeguards. A $10 Billion Expansion Is on the Table The industry’s growth plans are tied to roughly $10 billion in projected investment over the next decade. That capital would support new geothermal plants, drilling, land acquisition, environmental approvals, licensing, and grid-connected generation assets. For investors, the opportunity is significant: geothermal offers firm, dispatchable renewable power, which makes it strategically valuable in a system that increasingly needs stable clean energy. The Cas...

Three Pertamina Geothermal projects in Indonesia have secured $477 million in international financing

Geothermal Greenlight: How PGEO Just Unlocked $477 Million and a 40% Profit Surge By: Robert Buluma   If you follow clean energy in Southeast Asia, you already know the name: PT Pertamina Geothermal Energy Tbk (PGEO). But unless you've been staring at their Q1 earnings and the Indonesian government's newly released Green Book 2026, you might have missed just how massive this moment really is. In the span of one week, PGEO did two things that most renewable energy companies only dream of: 1. Secured $477.87 million in low-cost, sovereign-backed international funding. 2. Reported a 40% year-on-year net profit surge — to $43.90 million — on record electricity generation. That is not a coincidence. That is a flywheel . In this deep-dive blog post, we're going to unpack exactly what happened, why it matters for Indonesia's net-zero future, and how PGEO is quietly becoming one of the most compelling geothermal stories on the planet.

Eavor Demobilizes Rigs in Geretsried: What It Means for Closed-Loop Geothermal Investors, Heat Markets, and Project Risk

Eavor Demobilizes Rigs from Geretsried: What It Really Means for Closed-Loop Geothermal For three years, two drilling rigs on a farm estate near Geretsried, a Bavarian town about 40 km south of Munich, stood as the symbol of the world's most ambitious closed-loop geothermal experiment. Now in October 2026,  Eavor Technologies, the Calgary-based developer of the Eavor-Loop, has told the town and its heating utility that both rigs would leave the site . The company said keeping idle rigs and specialist services on site was costly, and that releasing them would help put the project in the strongest position to continue with Loop 2 once its commercial structure is reworked . On the surface, this is a logistics decision. Underneath, it is one of the clearest signals yet about where first-of-a-kind geothermal technology stands, and how hard it is to turn a technical proof into a bankable business. This article explains exactly what happened, what the move means and what it does not mean...

Endurance Energy Tests World's First Subsea Geothermal Well at Axial Seamount

Endurance Energy Tests the World's First Subsea Geothermal Well: What the Axial Seamount Demonstration Really Proved What if geothermal energy did not need a power plant on land? What if electricity could be produced directly from the Earth's heat beneath the ocean, with generators sitting on the seafloor and sending power to coastal grids? On October 19, 2026, Seattle-based startup Endurance Energy announced a major step toward that idea. The company said it had drilled and completed the world's first subsea geothermal well and placed a 3-ton test power plant nearly a mile beneath the Pacific. It also reported net-positive electricity from heat at an active underwater volcano, according to its announcement on PR Newswire. The headline numbers are modest. The Adélie prototype produced more electricity than it used for about 8.7 seconds. During that time it delivered a median net output of about 2 kilowatts and a peak of 16.5 kilowatts. One detail matters more than any other...

Geiselbullach Geothermal Project Confirms 10 MW District Heating Capacity

Geothermal milestone at Geiselbullach: 10 MW of heat confirmed after successful second deep well test On 15 August 2026 the Geiselbullach geothermal project reached a pivotal technical milestone: performance testing of the second deep production well completed successfully, delivering a sustained flow of 90 liters per second of thermal water at 79–80 °C. These measured parameters translate into roughly 10 MW of usable thermal power for district heating, enough to replace a portion of heat currently supplied by the municipal waste-to-energy plant (AHKW) and to create headroom for expanding the regional district heating network. The result confirms the project’s technical assumptions and moves the scheme into system-integration and commissioning activities ahead of planned commercial deliveries for the 2027 heating season. This article explains the test results and their significance, outlines the technical and operational consequences, and places the Geiselbullach development in the bro...

Menengai Geothermal Project Delays Expose Kenya’s Broken Steam Supply Model

Menengai’s Broken Promise: How Kenya’s Geothermal Model Lost the Steam Thematic image of the Olkaria Geothermal Field  Kenya’s Menengai geothermal project was sold as a model of modern public-private partnership. The state would carry the difficult and expensive burden of geothermal exploration and drilling. Private power producers would then build, own and operate power plants. Geothermal Development Company would supply the steam; the independent power producers would convert it into electricity; Kenya Power would buy the output. On paper, the arrangement was elegant. In practice, Menengai has exposed a far more uncomfortable reality: Kenya’s public steam-supply model is not delivering the certainty it promised. Menengai Phase I was designed to produce 105 megawatts from three 35 MW plants. GDC’s own project page says the three plants were awarded to Globeleq Menengai Geothermal, Sosian Menengai Geothermal Power and OrPower Twenty Two under a build-own-operate structure. Yet the ...

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 ...

Lithium Harvest Plans Alberta Geothermal Power and Lithium Project

Lithium Harvest’s Alberta Geothermal Project Could Combine Renewable Power and Domestic Lithium Production Lithium Harvest Holding A/S has signed a letter of intent with an unnamed geothermal development partner to establish a joint venture for an integrated geothermal power and lithium production facility in Alberta, Canada. At full nameplate capacity, the proposed project is expected to produce approximately 28,500 tonnes of lithium carbonate annually while generating 0.67 TWh of renewable electricity each year. The development would use a single geothermal resource to supply both baseload power and lithium-bearing brine for direct lithium extraction and refining.  A Dual-Output Geothermal Development The proposed Alberta facility reflects a growing effort to extract more value from geothermal resources than electricity generation alone. Traditional geothermal power projects produce electricity by bringing hot underground fluids to the surface. Depending on resource temperature a...

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...

Corva and Oliasoft Connect Well Design With Real-Time Drilling

Corva and Oliasoft Build a Continuous Learning Loop for Smarter Well Construction Introduction Corva AI and Oliasoft have announced a strategic collaboration designed to connect well engineering, real-time drilling operations and post-well analysis through a bidirectional digital workflow. The integration links Oliasoft WellDesign with Corva’s Real-Time AI platform, creating a continuous information loop in which engineering plans guide field execution and drilling results improve future well designs.  The partnership addresses one of the persistent weaknesses in modern well construction: the separation between planning software and operational systems. Although operators generate large volumes of engineering and drilling data, those datasets often remain fragmented across departments, applications and reporting processes. The result is slower decision-making, repeated manual work and limited transfer of lessons from one well to the next. By connecting design assumptions with liv...

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...
