TerraLithium and BHE Renewables have moved closer to commercial-scale lithium production after successfully extracting lithium chloride at a geothermal facility in California. The milestone marks progress in applying direct lithium extraction (DLE) technology to geothermal brine.
The project leverages BHE Renewables’ existing geothermal operations, which provide a continuous source of lithium-rich brine. DLE technology aims to recover lithium more efficiently and with a smaller environmental footprint than traditional evaporation ponds or hard-rock mining.
Infrastructure at the site repurposes geothermal energy for both power generation and lithium extraction, potentially reducing overall project costs. The companies have not disclosed specific timelines or capacity targets for scaling up to commercial output.
Geopolitical dynamics favor domestic lithium production as the U.S. seeks to reduce reliance on imports, particularly from China. The Inflation Reduction Act and other federal incentives support projects that strengthen the domestic critical minerals supply chain.
A transition context emerges as lithium demand grows from electric vehicle batteries and grid storage. While DLE promises lower water use and faster production than conventional methods, environmental concerns persist regarding brine disposal and wellfield impacts.
