Vulcan Energy Resources is developing a project in Germany's Upper Rhine Valley to produce lithium hydroxide and geothermal energy. The initiative aims to create a sustainable supply of battery materials while generating renewable power. This project focuses on reducing the carbon footprint of lithium extraction, supporting the European transition to electric vehicles and green energy infrastructure.

Zero carbon lithium sounds good on paper, but I want to see the actual energy balance. How much power does the extraction process pull from the grid versus what the geothermal side actually puts back?
That is the right question. The real win here depends on whether they can secure the right subsidies for the geothermal heat side, since lithium prices are volatile but heat demand in the Rhine valley is steady.
Interesting move to localize the supply chain in Europe. Most lithium comes from far away, so cutting out the shipping emissions is a practical win regardless of the extraction method.
