Vulcan draws on naturally occurring, renewable geothermal energy to power the lithium extraction process, and the process also creates a renewable energy by-product. This extraction method also uses significantly less water than traditional extraction methods and has a small footprint, according to the company. Vulcan has signed lithium offtake deals with Netherlands-based Stellantis (NYSE: STLA ), Renault (EPA: RNO ) and Volkswagen (OTC Pink: VLKAF ,FWB:VOW). Starting in 2026, Vulcan is set to deliver between 26,000 and 32,000 metric tons (MT) of battery-grade lithium chemicals for an initial six-year term to Renault, and between 34,000 and 42,000 MT of battery grade lithium hydroxide over a five-year term to Volkswagen. Aside from signing supply deals with automakers, Vulcan has inked agreements with battery materials maker Umicore (EBR: UMI ) and South Korea's LG Energy Solutions.
