Evoloh is an electrolyzer stack manufacturing company funded by Breakthrough Energy, The Engine, and other top investment firms. Rather than any single technological innovation, Evoloh’s hardware represents a comprehensive solution to the challenge of manufacturing low-cost electrolyzers with 100% domestic supply chains. Based around an anion exchange membrane, Evoloh’s electrolyzer stacks are made using earth-abundant materials like steel and plastic—with no need for the rare earths required by today’s predominant technologies. Paired with advanced manufacturing techniques borrowed from adjacent high-tech industries, Evoloh can lower the cost of manufacturing electrolyzer stacks by an order of magnitude.
