Captura designs and manufactures a PFAS-free bipolar membrane electrodialysis platform that generates acid and base streams for applications including direct lithium extraction, industrial water treatment, long-duration energy storage, and CO2 management. The platform was originally developed to power Captura’s Direct Ocean Capture (DOC) system, which removes CO2 from seawater for permanent storage or utilization. Captura operates the only U.S.-based production plant that produces complete electrodialysis systems and plans to scale domestic manufacturing capacity following its Series B raise. The company reports that its technology offers greater performance with significantly lower energy consumption and capital costs compared with leading market alternatives. Captura recently secured multiple purchase orders for its first electrodialysis stacks addressing the lithium extraction market, with initial deliveries expected this summer. CEO Steve Oldham says the company is now manufacturing systems for customers while continuing to advance commercial deployment of DOC globally.
