Abstract
The hybrid desalination and energy production system includes a desalination system for separating seawater into purified water and brine, an electrodialysis system for treating the brine and outputting low salinity water, a hypersaline brine solution, and H2 gas; an evaporator for treating the hypersaline brine solution and outputting salt and water vapor; a superheater for treating the water vapor and outputting a superheated water vapor; a turbine for receiving the superheated water vapor to generate energy; a gas scrubber for receiving the H2 gas from the electrodialysis system and producing dry hydrogen; and a hydrogen cell for receiving the dry hydrogen and outputting energy. A condenser converts the vapor into condensate and low salinity water. A desalinated water collection tank receives the desalinated or low salinity water. A pressure retarded osmosis system receives the brine, the low salinity water, and condensate from the condenser to produce dilute brine.
