A process, apparatus and system for reverse electrodialysis utilizing a supply of salt water and a supply of fresh water by passing the liquids through many cells of a battery comprising the improvements (independently or in any combination), (1) The salt water is fed to a battery through a distributor such that electric current is not free to pass along a salt water conduit between a first group of cells and a second group of cells: (2) One or more batteries operate as a heat exchanger to warm up the salt water and fresh water to a temperature above ambient temperature: (3) Salt water for reverse electrodialysis is pumped through one or more batteries by means of tidal power, and fresh water is pumped through one or more batteries by means of hydrostatic head available from a river. p |
