DESALINATION SYSTEM CAPABLE OF PRODUCING HYDROGEN

A desalination system for enabling hydrogen production according to an embodiment of the present invention includes a desalination process unit in which influent is water-treated through a reverse osmosis process to produce produced water and concentrated water; and a chlor-alkali process unit having an interior space partitioned into an anode section to which the concentrated water is supplied and a cathode section to which the produced water is supplied, wherein the chlor-alkali process unit uses solar electrical energy to generate chlorine gas from salt of the concentrated water through a chemical reaction at the anode section with the concentrated water as an electrolyte, and generate hydrogen gas and sodium hydroxide through a chemical reaction at the cathode section with the produced water as an electrolyte.
