Veridia Energia, an Oregon start-up, is developing a breakthrough green energy technology for the long-term storage and cost-effective use of grid-level distributed renewable energy sources, including solar, wind and hydropower, employing a novel NaKCl “liquid metal” energy storage system. Although partially resembling both alkali metal primary batteries and the electrowinning of metals and employing well-known techniques of fuel cells and of electroplating, this proprietary combination of materials, technologies, and methods is unique and has never been employed as an electrical energy storage system.
