Sustainable Geothermal Lithium Triangle in the Upper Rhine Graben

Currently, the co-production of lithium from deep geothermal plants is being discussed worldwide and has already been implemented locally on a pilot basis. Especially in the field of electro vehicles, the demand for lithium is increasing rapidly. In Europe, there are well identified exploitable resources for lithium in the Upper Rhine Graben from Alsace in France to Germany near Mannheim where the deep geothermal brines reveal lithium contents up to 200 mg/L.

In particular, the geothermal sites in Landau, Bruchsal, and Soultz-sous-Forêts indicate a sustainable lithium source in the subsurface, as they show constant lithium contents for more than 10 years of plant operation, forming the sustainable geothermal lithium triangle in the Upper Rhine Graben. The Insheim and Rittershoffen geothermal sites are also part of this region.
