An interesting perspective from Pierre Brossollet, CEO of ARVERNE Group, on the role geothermal energy and geothermal lithium could play in strengthening France's energy and industrial sovereignty. A few points that stood out to me: • France also recognises geothermal as strategic tool to reduce dependence on imported natural gas and support decarbonisation goals. • Arverne sees significant untapped potential in the French subsurface, citing an estimated 300 TWh geothermal heat resource, with geothermal potentially covering 20-30% of France's heating demand by 2040. • Through its Lithium de France project in Alsace, the company aims to combine geothermal heat production with domestic lithium extraction, targeting up to 27,000 tonnes of lithium carbonate equivalent per year, enough to cover around 30% of France's annual lithium needs. • The interview also highlights a broader theme that is increasingly relevant across Europe: linking energy security, industrial competitiveness, critical minerals, and local economic development through subsurface resources. As geothermal gains momentum across Europe, it is encouraging to see more companies and policymakers looking at the full value of the resource, from heat and power to critical minerals. #Geothermal #EnergyTransition #Lithium #France #Decarbonisation #EnergySecurity
