A process to produce green hydrogen directly from seawater using renewable electricity.

A device that uses a porous, fluorine-rich membrane to separate seawater from a concentrated potassium hydroxide electrolyte solution, enabling direct hydrogen production from saltwater.

A previous approach to resist corrosion from chloride ions in seawater electrolysis, though not suitable for practical application.

A hydrogen production device that splits saltwater directly using a fluorine-rich porous membrane to separate seawater from a concentrated potassium hydroxide electrolyte solution. The device overcomes corrosion and side-reaction problems inherent in traditional seawater electrolysis and has demonstrated operational durability exceeding 3,200 hours.
