We assess Vulcan's Green Financing Framework as Dark green. Founded in 2018, Vulcan owns the largest combined geothermal energy and lithium resource in Europe, located in the Upper Rhine Valley in Germany and France. It produces both renewable energy and lithium from the same sub-surface brine source. Brine is water with a high concentration of salt. By enhancing the existing technology for the efficient production of lithium from geothermal brine, Vulcan aims to create a local source of sustainable lithium for Europe.
