Researchers at Berkeley Lab met with U.S. Department of Energy (DOE) Secretary Jennifer Granholm last week to discuss the #lithium potential at the Salton Sea geothermal field in Lithium Valley. This critical mineral is the primary potential #geothermal resource for lithium in the U.S., according to Patrick Dobson, who leads a project to quantify how much lithium exists there and how to source it in an environmentally sustainable way.

Researchers from EESA and the Energy Technologies Area (ETA) met with U.S. Department of Energy Secretary Jennifer Granholm during her visit to Berkeley Lab for a DOE Advisory Board meeting. They discussed with her their work analyzing the lithium resource potential at the Salton Sea Geothermal Field. The project led by Pat Dobson, Geothermal Systems Program Lead, aims to quantify how much of that lithium can be extracted in a sustainable way.

California has committed to 60 percent renewable energy by 2030. With an urgent need for lithium to help facilitate this transition, Pat Dobson is leading a project to investigate lithium extraction in California’s Salton Sea region, and was featured in a CapRadio Q&A to discuss the research details.

As the United States seeks to wean itself from fossil fuels, attention is turning to California and its vast reservoir of lithium – an essential component of rechargeable batteries used for electric vehicles, mobile phones, and to store energy from wind and solar power.

The Salton Sea geothermal field in California potentially holds enough lithium to meet all of America’s domestic battery needs, with even enough left over to export some of it. But how much of that lithium can be extracted in a sustainable and environmentally friendly way? And how long will the resource last? These are just a few of the questions that researchers hope to answer in a new project sponsored by the U.S. Department of Energy (DOE).
