How does geothermal lithium compare with other extraction processes?
Romain Millot - This is a highly innovative approach in which Lithium de France, a subsidiary of the Arverne Group, an environmentally-committed company, is leading the way. Alongside traditional mining in rock, and the salt flats found in South America, where lithium precipitates, geothermal lithium combines deep geothermal energy, which supplies heating networks, with the extraction of lithium from geothermal water. This process has the merit of a reduced impact and it meets the demand for relocation of the lithium sector for batteries (electric mobility). It is a tool for decarbonisation and sovereignty.
BRGM's data, digital services and geomodelling capabilities are essential for innovative projects such as exploiting geothermal lithium.
