Vulcan Energy's Lionheart lithium project

under development

Australian-listed Vulcan Energy is developing Europe's first integrated, low-carbon lithium supply chain in Germany's Upper Rhine Valley. The project involves geothermal brines, direct lithium extraction, and chemical conversion all controlled within a 100km radius of the Lionheart project. It plans to co-produce baseload renewable geothermal power and heat while extracting lithium hydroxide for European battery plants, targeting short intra-EU logistics instead of importing spodumene or brine products. The project couples deep geothermal wellfields with closed-loop brine handling and on-site refining, tightening interfaces between subsurface, plant design, and offtake.
