Application of the fusion reactor for hydrogen production from water
Abstract
The non-conventional methods of hydrogen production by means of splitting water through such cycles as the thermochemical-electrochemical hybrid cycle, the high temperature electrolysis cycle and two-step thermochemical cycle are discussed. Eight thermochemical-electrochemical hybrid cycles are presented including the SO2-H2O-H2SO4 cycle. Process evaluation and efficiency of the application of fusion energy to high temperature electrolysis of steam (FR-HTE) are investigated. The thermal efficiency for the FR-HTE process can range between 41 and 66% for a fusion reactor steam temperature of 1500 K and power cycle efficiencies ranging from 38 to 70%. A two step thermochemical cycle based on the Fe3O4-FeO system is described. Application of fusion reactor to this two-step cycle has been investigated and process efficiency for hydrogen production up to 74.4% can be obtained at fusion blanket temperatures up to 2500 K. The high temperature electrolysis process appears to have significant advantages over the others.
