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...
Unlocking the Power of Offshore Geothermal Energy: CGG's Groundbreaking White Paper In a world where the quest for sustainable energy sources is more critical than ever, CGG, a leading global technology and Earth science company, has unveiled a groundbreaking white paper shedding light on the vast potential of offshore geothermal energy. This renewable resource, harnessed from the magmatically active ocean floor spreading centers and flooded rift systems, presents a promising avenue for meeting the world's energy needs while mitigating environmental impacts. The research conducted by CGG scientists underscores the abundance of untapped geothermal resources lying beneath the ocean's surface. These offshore areas, characterized by their geological activity, offer an ideal environment for extracting geothermal energy alongside other valuable by-products such as freshwater, Green Hydrogen, and ammonia. This innovative approach not only diversifies the renewable energy mix but a...
