The Salton sea’s hidden heat powers a modern lithium rush

Beneath the Salton Sea’s arid surface lies a vast geothermal basin holding supercritical fluid rich in lithium, dubbed “Lithium Valley.” This region is poised to become a hub for clean energy and battery mineral manufacturing, aiming to extract lithium directly from geothermal brines. Engineers are developing innovative electrochemical processes to overcome extraction challenges, potentially securing the U.S.
