Arverne Group SA (ARVEN.PA) is a France-based energy transition company specializing in the recovery and valorization of subsurface resources for renewable geothermal energy and low-carbon lithium extraction. Founded in 2018 and headquartered in Pau, France, the company operates as an integrated industrial player across the underground value chain, including exploration, drilling, production, and sales to end-users, with sites in Pau, Haguenau, Schiltigheim, Maisse, and Paris. It focuses on serving local communities and industries in France through its subsidiaries, such as 2gré for geothermal heat sales, Lithium de France for geothermal heat and lithium extraction, and Arverne Drilling Services for drilling operations; core offerings encompass geothermal heating and cooling networks, low-carbon lithium for electric vehicle batteries, shallow geothermal installations, and drilling and well construction services.
The company targets decarbonization in sectors like district heating, industrial processes, and critical minerals supply, primarily in France with projects in regions such as Île-de-France and Nouvelle-Aquitaine. Arverne Group positions itself as the leading French supplier of geothermal solutions, producing sovereign, short-circuit energies from geothermal brines.
Recent developments include strengthening its stake in Lithium de France to 73.8% through a contribution agreement with Hydro Energy Invest AS (completed October 2025) and a second Series B funding round of €40 million alongside Equinor Ventures (September 2025); it also formed a strategic partnership with Crédit Agricole Pyrénées Gascogne Énergies Nouvelles for geothermal project financing and development in Nouvelle-Aquitaine, and launched the first geothermal drilling for the Lithium de France project (November 2025). In July 2025, construction began on major district heating networks in Clichy-sous-Bois and Livry-Gargan under its first public service concession with Dalkia and SAS IdF Energies & Territoires. Additionally, Bpifrance acquired a 4.3% stake, and the company initiated testing of innovative shallow geothermal technologies via subsidiary DrillHeat as part of an ADEME-funded project (March 2025).
