INTEGRATION OF A HIGH TEMPERATURE STEAM ELECTROLYSIS PLANT FOR HYDROGEN PRODUCTION WITH THE POWER CYCLE OF A SUPERCRITICAL WATER-COOLED REACTOR

摘要

High Temperature Steam Electrolysis (HTSE) is currently under development as an alternative process for large-scale hydrogen production. A HTSE plant and the power cycle of the Supercritical Water-Cooled Reactor (SCWR) were modeled separately and then as an integrated system. Different options for steam diversion from the power cycle to the HTSE plant have been analyzed, with the optimal option selected based on maximizing the overall efficiency. This paper discusses the models of the SCWR power cycle and the HTSE plant, the assumptions required to develop these models, and the analyses conducted to determine the most efficient way to integrate the two systems.
