Water separation device solves the puzzle of producing hydrogen directly from seawater

A combined desalination and electrolysis system capable of producing green hydrogen directly from seawater has been developed by a team in China. This integrated process uses a low-energy method to purify seawater, making it one of the first viable approaches to using saltwater as a source of hydrogen. The purification step uses phase transitions to …
