Berkshire Hathaway Energy, the energy group owned by investment tycoon Warren Buffett, has linked with oil giant Occidental to produce lithium in the US.

Berkshire Hathaway’s BHE Renewables subsidiary has formed a joint venture (JV) with TerraLithium, a unit of Occidental developing Direct Lithium Extraction (DLE) technologies.

TerraLithium’s DLE is said by the partners to enable the processing of high-purity lithium from brine in “an environmentally safe manner”, potentially widening access to the key energy transition material that’s used in batteries for EV and grid storage applications.
