Arverne expands geothermal asset portfolio with new lithium exploration permit in Auvergne Arverne secures 442.7 km² PER “Bassin de Limagne” near Clermont-Ferrand French geothermal developer Arverne (Euronext: ARVEN) has been granted an exclusive research permit (Permis Exclusif de Recherches, PER) for lithium and related substances covering the “Bassin de Limagne” in Puy‑de‑Dôme, Auvergne. The five‑year permit, announced 3 September 2026, spans 442.68 km² and adds to Arverne’s growing national portfolio of PERs: the company now holds nine permits in France, three of which are focused on lithium. The award underscores Arverne’s strategy to combine geothermal heat production with geothermal lithium extraction — an integrated model the company is already deploying elsewhere in France. For the Auvergne permit, Arverne emphasizes that the Bassin de Limagne area overlaps with its existing PER for the Riom‑Clermont‑Métropole, where 3D exploration studies have previously evaluated the subsurf...

US Geothermal Tax Credits in 2026: What Is Actually Still Alive After OBBBA For an industry that spent more than a decade building financial models around a stable federal incentive structure, 2026 has been a year of whiplash. The 30% federal geothermal tax credit that developers and homeowners built forecasts around is gone in one form and still alive in another, and even the IRS’s own public guidance has been confusing enough to trigger uncertainty across the market. That confusion is not a minor clerical issue. It is shaping investment decisions, contractor sales pitches, homeowner timelines, and project finance assumptions right now. If you work in geothermal, the key question is no longer whether federal incentives exist, but which incentive applies, to which project type, and under what ownership structure. The law that changed the timeline To understand where things stand in 2026, you have to start with the Inflation Reduction Act of 2022, which created a long runway for clean e...

Who Is Really Funding Next-Gen Geothermal in 2026? Next-generation geothermal has moved beyond laboratory research into a capital-intensive commercialization phase. In 2026, the most important financing is no longer coming from one investor category: venture capital funds are financing drilling, subsurface modelling and hardware; strategic energy companies are providing equipment, project access and market credibility; banks are beginning to lend against contracted projects; and governments are absorbing exploration and first-of-a-kind technology risk. The strongest financing activity is concentrated in the United States and Canada, but Europe is becoming increasingly important through Germany-based deployment, European Union grants, UK innovation support, and strategic participation from European energy companies. The central investment question is changing from “Can this technology work?” to “Can the developer deliver repeatable, financeable projects at commercial cost?” The 2026 fun...

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 ...

Strataphy Partners With HUMAIN to Deploy PrimeLoop Cooling Across Saudi Arabia’s AI Data Centers Saudi Arabia is moving rapidly to establish itself as a global artificial intelligence and data-center powerhouse, and one of the most important challenges facing that ambition is not simply how much computing capacity can be installed, but how efficiently that computing capacity can be cooled. At LEAP 2026, Strataphy announced a partnership with HUMAIN to deploy its PrimeLoop® cooling technology across HUMAIN’s data-center infrastructure in the Kingdom of Saudi Arabia. According to the announcement, the engagement represents the first deployment of its kind for PrimeLoop® in Saudi Arabia and is designed to address one of the fundamental constraints of large-scale AI infrastructure: thermal management. The partnership comes as HUMAIN works toward a target of approximately 6 GW of AI compute. At that scale, cooling becomes a strategic infrastructure issue rather than a conventional dat...

Closed-Loop Geothermal Systems: The Companies Building the Next Generation of Underground Energy Image : The Eavor Technologies Geothermal Project  Closed-loop geothermal systems represent one of the most promising frontiers in renewable energy, offering continuous, baseload power without the environmental concerns associated with conventional geothermal development. Unlike traditional open-loop systems that require hydraulic fracturing and consume large volumes of water, closed-loop geothermal circulates a working fluid through sealed underground pipes, extracting heat from hot rock formations while maintaining a self-contained system that eliminates fluid loss, induced seismicity, and reservoir depletion risks.This technology has attracted significant investment and technical innovation from a diverse array of companies spanning startups, established energy firms, and drilling specialists, each pursuing distinct approaches to unlock the vast thermal energy stored beneath the Eart...

Unlocking the Impermeable Reservoir: Lessons from a 30-Year Reservoir Engineer An Alphaxioms interview with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Context: Menengai East and Olkaria Central. Every geothermal developer knows the moment.  The rig is gone and the money is spent. The well is drilled to depth, the temperature is there, and then the well will not flow. The heat is real, but the connection between the well and the reservoir is not. Wells like this sit at the centre of one of the most important questions in geothermal development: what do you do with a tight reservoir? Walk away and drill again, or find a way to unlock what is already there? To explore the question, Alphaxioms spoke with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Richard brings 30 years of global experience in geothermal energy.  We framed our questions around two settings, Menengai East and Olkaria Central, and asked him how ...

Global Geothermal Investment 2026: 15 Markets Where Developers Should Look Next Geothermal energy is entering its most investable decade yet, with developers, drilling contractors, turbine suppliers and private capital providers scanning a widening map of opportunities beyond the traditional “big five” producers.  This article profiles 15 markets where project pipelines, policy signals, resource quality and technology readiness converge to create compelling entry points in 2026 and beyond.  Why 2026 Is a Turning Point for Geothermal Capital Global geothermal investment is accelerating as governments seek firm, low‑carbon baseload to back up variable wind and solar, while advanced drilling and subsurface engineering lower costs and expand the resource base. Market analysts project the geothermal energy market to reach roughly USD 13.56 billion by 2030, up from about USD 9.81 billion in 2025, implying sustained double‑digit growth in development spend. Capital is flowing not onl...
