Arverne Group will begin construction of the geothermal Direct Lithium Extraction (DLE) demonstrator for its Alsatian project.
Located in the Bas-Rhin region, the demonstrator will play a key role in assessing lithium resources as well as showcasing the technical and economic performance of the innovative DLE technology in real-life situations. The technology will validate the lithium extraction process from geothermal brines in the Rhine Basin.
The construction of the demonstrator benefits from the support of BPI France, a project financed by the Government as part of France 2030 and financed by the European Union – Next Generation EY as part of the France Relance plan.
The equipment was designed in collaboration with DG SKID, a recognised expert in the field, following the pilot phase conducted by Lithium de France in Norway. The demonstrator will be installed in Northern Alsace, on the first geothermal doublet, which will start over the coming months.
Pierre Brossollet, Founder and CEO of Arverne Group, said, “The construction of the geothermal lithium extraction demonstrator marks a key step in the pre-industrial phase of our strategic project. We are continuing our roadmap to achieve, by 2031, an annual production capacity of 4TWh of geothermal heat and 27,000 tonnes of geothermal lithium, a critical metal in the energy transition, meeting the growing needs of the electric mobility and energy storage markets.”
