About

Founded in 2017, Vulcan Energy Resources is a private company headquartered in Karlsruhe, Germany with approximately 201-500 employees specializing in Geothermal, Hydrogen.

Vulcan Energy Resources is a renewable energy and sustainable materials company developing integrated geothermal energy and lithium extraction projects in the Upper Rhine Graben. The company aims to produce climate-neutral lithium hydroxide monohydrate for European battery manufacturers while generating renewable heat and electricity for regional customers. Operating proven deep geothermal technology at depths of 2,500-4,000 meters, Vulcan extracts lithium from naturally occurring geothermal brine using its proprietary direct lithium extraction process (VULSORB). The Lionheart project, currently under construction, will produce up to 24,000 tonnes of lithium hydroxide monohydrate annually and supply 300 MW of renewable heat for district heating networks, sufficient for approximately 500,000 electric vehicle batteries. The company also operates the Insheim geothermal power plant, supplying renewable electricity to over 6,500 households since 2012.
