Reuters reported last month that Exxon had agreed to study ways with Tetra Technologies Inc (TTI.N) to develop more than 6,100 acres (24.7 square kilometers) in Arkansas containing lithium-rich brine. Exxon also earlier this year bought more than 100,000 acres in Arkansas from privately-held Galvanic Energy.Extracting lithium from those brines will require Exxon to chose a direct lithium extraction (DLE) technology, something it has not yet done. Additionally, no DLE technology has ever worked at commercial scale, although multiple companies are racing to be the first.Reuters also reported last month that Exxon has held talks with International Battery Metals (IBAT.CD) about licensing DLE technology.
