By Robert Buluma Alphaxioms
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...

GEL Technical Grade Lithium Milestone Boosts UK Geothermal Supply

By Robert Buluma Alphaxioms
GEL’s Technical-Grade Lithium Milestone Could Reshape UK Critical Minerals Supply Geothermal Engineering Ltd’s latest announcement is an important step for the UK’s lithium ambitions. The company says lithium carbonate produced from deep geothermal brine at United Downs now meets the 99.3% purity threshold for technical-grade material, which means it can be sold directly to battery supply chains without further refining.   Why this milestone matters This is significant because it moves geothermal lithium closer to commercial relevance, not just technical proof. A material that already meets market specification is much easier to integrate into downstream battery and industrial supply chains. It also strengthens the case that geothermal brines can support both clean power generation and critical minerals production from the same asset base.   For the UK, the timing is especially relevant. The government has set a target of meeting 10% of domestic critical mineral de...

Quaise Energy’s Project Obsidian in Oregon: The World’s First Commercial Superhot Geothermal Plant

By Robert Buluma Alphaxioms
The New Energy Frontier: Quaise Energy’s Superhot Geothermal Gambit in Oregon By Alphaxioms Editorial Team | September 4, 2026 In the high desert of Central Oregon, a project with implications far beyond Deschutes County is taking shape. Quaise Energy, now backed by a total of $280 million in funding, is advancing Project Obsidian, which it describes as the world’s first commercial superhot geothermal power plant . The company says the first phase is designed to deliver 50 MW by 2030, with a pathway toward 250 MW and ultimately more than 1 GW . Before the first megawatt reaches the grid, however, the project faces a local policy test: whether Deschutes County should grant a five-year property tax abatement under Oregon’s Rural Renewable Energy Development Zone Program. That decision is more than a routine incentive request. It is a referendum on how rural counties choose to support next-generation energy infrastructure and whether older incentive frameworks can accommodate a technolog...

Mazama Energy Athena Drilling Milestone Boosts Superhot Rock Geothermal Economics

By Robert Buluma Alphaxioms
Mazama Energy’s Athena drilling milestone points to a new phase for superhot rock geothermal Mazama Energy says its Athena well at Newberry, Oregon reached 10,350 feet in 15 drilling days, cutting the drilling time to the same depth by 80% versus its 2025 result. The company says the performance supports a broader case for superhot rock geothermal as a lower-cost, scalable source of firm power.   A faster drilling result Mazama’s update is important because drilling speed is one of the biggest cost drivers in geothermal development. Reaching the same depth in 15 days instead of the much longer 2025 campaign suggests the team is learning quickly and improving operational efficiency. The company also reported instantaneous rates of penetration above 350 feet per hour and sustained rates above 130 feet per hour over extended intervals.   That matters because geothermal economics often hinge on whether drilling can be made predictable, repeatable, and cheaper over time. ...

Ireland’s Deep Heat: Surveying Geothermal Potential Beneath Dublin

By Robert Buluma Alphaxioms
Dublin’s seismic survey will map deep underground geology to assess geothermal potential, reduce uncertainty, and support future clean, local energy development Dublin is about to become a live laboratory for one of the clean energy questions of the decade: can the heat stored deep beneath the city help warm homes, offices, schools, and hospitals? The answer is not known yet, but the Dublin Seismic Survey is designed to find out by mapping the geology 2 to 3 kilometres underground with a safe, non-invasive method that has already been used successfully in other European cities . A city listening underground At street level, the survey may look deceptively simple: a specialist truck pauses at intervals, presses a vibration plate to the road, and sends controlled energy into the ground. That energy bounces off different rock layers and structures, then returns to sensors along the route, where it is recorded and processed into images of the subsurface . The process is built around precis...
