Exxon Mobil and Tetra Technologies Inc. are planning to construct both a bromine production facility and a lithium brine extraction manufacturing facility along the Columbia-Lafayette county line. A bromine-based electrolyte for long-duration energy storage has recently been brought to the market by Tetra. Bromine is also in demand for fire retardants for electric vehicles. The same saltwater brine Tetra proposes to produce from its prospective production field may also be used to produce lithium. Tetra plans to drill five brine supply wells in Columbia County, and also five injection wells to send the brine back into the Smackover Formation once bromine is extracted. The project is valued at $500 million. Tetra Technologies Inc., 24955 Interstate 45, The Woodlands, Texas, 77380. DR#23-00297709.
