Abstract:
1. A dual pressure hybrid sulfur process for hydrogen generation, utilizing the decomposition of H 2 SO 4 to H 2 O, SO 2 and O 2 with heat from a nuclear reactor or natural gas fired combustor, which comprises: (a) utilizing a sulfur cycle, selected from the group consisting of a Westinghouse Sulfur Process and a Sulfur Iodine Process, wherein an electrolyzer provides H (b) passing the H (c) inputting electricity to the plurality of electrolyzer units to produce hydrogen gas and H (d) supplying electricity to the plurality of electrolyzer units utilizing a Rankine Cycle Power Conversion Unit; and (e) supplying fluid heat to the Rankine Cycle Unit and the sulfur cycle, utilizing a heat source selected from the group consisting of a nuclear reactor and a natural gas fired combustor; where the decomposition reactor operates at a pressure higher than the scrubber and electrolyzer units, providing a dual pressure hybrid process.
