Rio Tinto, General Motors and even the U.S. Energy Department are investing heavily in a crop of newer technologies that could revolutionize the way lithium is produced for electric vehicle batteries.If they do, miners will be able to boost global lithium production with a footprint far smaller than open-pit mines and evaporation ponds, which often are the size of multiple football fields and unpopular with local communities.
Granholm's department has given Warren Buffett's Berkshire Hathaway Inc a $15 million grant to test DLE technology at California's Salton Sea, under which sit large geothermal lithium deposits, and is considering funding other DLE projects. Privately held Lilac Solutions Inc, backed by BMW and Bill Gates' Breakthrough Energy Ventures, developed that technology and said it could use a desalination plant to filter brackish water to avoid using potable water.
Standard disputed the allegations in the report, which erased more than $300 million in Standard's market value in one day and stoked fears about the DLE movement. The stock has partially recovered.There are dozens of DLE-focused companies worldwide, some with their own technologies, some with brine-rich acreage and some with both.
Galvanic Energy LLC aims to sell to sell the 100,000 brine-rich acres it controls in Arkansas if it finds a DLE technology that works.
