Geothermal Engineering Ltd operates the United Downs geothermal site in Cornwall and has developed commercial‑scale lithium extraction from geothermal brine, marking the UK's first such operation. The company's initial lithium production capacity began at 100 tonnes per annum, and GEL plans to scale output to over 18,000 tonnes per annum within the next decade. That target production is projected to supply roughly 250,000 EV batteries annually, or about 65% of the UK's 2024 BEV registrations. United Downs is also notable as the UK's first deep geothermal power plant. GEL has secured UK government DRIVE35 grant funding to accelerate expansion of its lithium extraction operations at United Downs. The articles do not disclose GEL's revenues, prior funding rounds, or the monetary value of the grant.
