Arverne Group has secured strategic-project status under the EU Critical Raw Materials Act for its Lithium de France development in Alsace, strengthening the project’s position as it prepares to finance a planned geothermal operation targeting approximately 27,000 tonnes of lithium carbonate annually.
The project combines lithium extraction from geothermal brines with renewable heat production, creating two potential revenue streams from the same geothermal resource. Arverne is targeting an operating life of around 30 years, with approximately 2.2 TWh of geothermal heat production planned over the project’s development.
EU Strategic Status Supports Development
The European Commission’s strategic designation is intended to facilitate permitting procedures and improve access to European financing mechanisms. It does not constitute a construction permit, a final investment decision or a commitment of new funding. For Arverne, the next priority is securing the capital required to move Lithium de France towards commercial development. The project must still complete detailed engineering, obtain the remaining permits and establish a financing structure capable of supporting construction.
Financing Plans Target 2027 Debt Milestone
Arverne has already secured a convertible financing arrangement of up to €33 million, supported by Arverne and Equinor Ventures. The company is also preparing a larger project-finance package with Macquarie and Crédit Agricole CIB. An initial tranche of senior debt is targeted for 2027, although the financing discussions have not yet resulted in a confirmed commitment for the full project.
Initial lithium production is planned for 2028. Achieving that target will depend on completing engineering work, securing regulatory approvals and raising sufficient debt and equity to fund construction and commissioning.
Geothermal Lithium Offers an Alternative Production Model
Lithium de France is designed to recover lithium from geothermal brines, rather than relying on conventional hard-rock mining or evaporation ponds. The same geothermal system would also supply renewable heat. This integrated approach could reduce some of the environmental impacts associated with traditional lithium extraction methods while supporting domestic European production. However, its environmental and commercial performance must be demonstrated at the planned industrial scale.
The main technical challenge is integrating lithium recovery, brine reinjection and geothermal energy production into a reliable operating system. The project must demonstrate that these processes can function together while maintaining the targeted production levels.
Technical Performance Will Shape Bankability
Before lenders can commit substantial project financing, Lithium de France will need to establish dependable operating parameters, including brine chemistry, lithium recovery rates, operating costs and long-term geothermal reservoir performance. These factors will influence production reliability, project economics and the ability to sustain operations throughout the planned 30-year life.
Although EU strategic status strengthens the project’s policy position, it does not eliminate the technical, financing and development risks associated with a new industrial operation.
2027 Financing Will Be a Critical Milestone
The next steps include completing bankable engineering, finalising the financing structure and converting senior-debt discussions into committed capital. If Arverne secures the required funding and completes the remaining development work, Lithium de France could advance towards construction, positioning the project to contribute to Europe’s domestic lithium supply while producing geothermal heat. For now, the principal milestones remain financing, permitting and proof that the integrated geothermal-lithium process can deliver reliable commercial performance ahead of the targeted 2028 start of production.
