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...
Eavor & SLB: Unlocking a Revolution in Clean Energy Production

Imagine a world where energy is not only clean but also consistent, dependable, and accessible worldwide. This vision is becoming a reality, thanks to an innovative partnership between Eavor Technologies and SLB (formerly Schlumberger). Together, they are pioneering a groundbreaking approach to harnessing renewable energy, promising to redefine how we produce and consume power and heat.
At the heart of this collaboration lies Eavor's revolutionary technology, the Eavor-Loop™, a closed-loop geothermal system that is unlike anything seen before. The partnership reached a critical milestone recently at Getesried, the home of the first commercial Eavor-Loop™, where the SLB and Eavor teams met to celebrate this transformative project.
What Is the Eavor-Loop™?
The Eavor-Loop™ is a closed-loop geothermal system that eliminates the traditional challenges of geothermal energy. Unlike conventional geothermal systems, which rely on tapping into naturally occurring reservoirs of hot water and steam, Eavor-Loop™ creates its own subsurface reservoir by circulating a proprietary working fluid through a network of sealed underground wells.
This fluid absorbs heat from the Earth and transfers it to the surface, where it can be used to generate electricity or provide direct heating. The system is entirely self-contained, which means:
No emissions: No greenhouse gases or harmful chemicals escape into the atmosphere.
No water use: It doesn’t depend on groundwater, making it sustainable and environmentally friendly.
No depletion: The loop ensures a steady supply of heat without exhausting the Earth's resources.
Why Does It Matter?
The Eavor-Loop™ represents a paradigm shift in renewable energy. Unlike solar and wind, which are intermittent and depend on weather conditions, the Eavor-Loop™ provides firm and consistent power and heat. This reliability makes it ideal for powering industries, homes, and even entire cities without the need for expensive energy storage systems.
Additionally, its adaptability means it can be deployed almost anywhere, unlocking geothermal potential in regions previously considered unsuitable. This global applicability could democratize access to clean energy, leveling the playing field for developing and developed nations alike.
The SLB Partnership: Accelerating Innovation
SLB brings decades of expertise in drilling and subsurface technologies to the table, making it the perfect partner for Eavor. By combining SLB's advanced engineering capabilities with Eavor's visionary technology, the two companies are pushing the boundaries of what geothermal energy can achieve.
The collaboration at Getesried, a site that symbolizes the dawn of this new energy era, showcases how partnerships between innovative startups and established industry leaders can drive transformative change.
The Benefits of This Revolution
1. Climate Action: The Eavor-Loop™ provides a scalable, low-carbon energy solution that could significantly reduce global greenhouse gas emissions.
2. Energy Security: By tapping into an infinite and locally available resource—Earth’s heat—countries can reduce their reliance on fossil fuels and imported energy.
3. Economic Growth: The widespread adoption of this technology could create thousands of jobs in drilling, manufacturing, and maintenance while boosting local economies.
4. Global Accessibility: From deserts to dense urban areas, the Eavor-Loop™ can bring energy independence to regions previously sidelined in the renewable energy revolution.
A Future Powered by Innovation
The meeting at Getesried is more than a corporate milestone—it’s a glimpse into the future. A future where energy is no longer a privilege but a universal right, where innovation leads the way to sustainability, and where partnerships like that of Eavor and SLB redefine the possibilities of human ingenuity.
As the world grapples with the dual challenges of climate change and energy security, solutions like the Eavor-Loop™ shine a light on a better, cleaner, and brighter tomorrow. It’s not just about technology; it’s about transforming the very foundation of how we live, work, and power our world.
This is the revolution we’ve been waiting for, and it’s happening now. Are you ready to join the journey?
