Abstract: A process and system for indirect seawater, and other contaminated waters, electrolysis are provided. The system includes a pressure retarded osmosis unit including a semipermeable membrane, and a high pressure electrolyzer unit including an anode and a cathode, with an osmotic agent solution being circulated at high pressure between the draw side of the pressure retarded osmosis unit and the electrolyzer unit. The osmotic agent solution is diluted in the PRO unit as molecular water is drawn into it from the feed solution side through the semipermeable PRO membrane, and it is concentrated in the electrolyzer unit as molecular water is removed by electrolysis. The PRO process supplies the electrolyzer with the required molecular water for electrolysis and maintains a high pressure of the electrolyzer feed.
