Geothermal Energy Potential in Lithium Extraction for Battery Production
Research indicates that geothermal energy could provide both heat and lithium, enhancing Europe's resource supply and reducing import dependence. This dual-use approach may improve the economic viability of geothermal projects while supporting local battery manufacturing.

A recent study suggests that deep geothermal energy could be harnessed for lithium extraction, potentially yielding up to 26.5 million tons of lithium metal in Germany's North German Basin. By applying Direct Lithium Extraction (DLE) methods to thermal water, this approach not only provides renewable heat but also creates an additional revenue stream through lithium production.
While European lithium needs will not be fully met by this method, localized sources may improve supply security and reduce transport distances. The feasibility of this model hinges on factors such as lithium concentration, sustainable extraction rates, and the integration of heat and lithium recovery systems. Companies like Vulcan Energy are already pursuing similar initiatives, indicating a trend towards maximizing existing infrastructure.
