Sulfur hydrogen production system

The Hybrid Sulfur (HyS) thermochemical cycle task addresses the key technology issues involved in the development of a hybrid sulfur hydrogen production system - including the SO2 - H2O electrolyzer design, SO2/O2 separation, and the unique materials and process issues associated with the acid decomposition section. An electrolyser is being developed that can be used in conjunction with the sulfuric acid decomposition section being developed for the S-I cycle in a Hybrid Sulfur Integrated Laboratory-Scale Experiment. 

SULFUR CYCLE HYDROGEN PRODUCTION SYSTEM MAJOR PROCESS PARAMETERS FOR A COMMERCIAL SYSTEM... 

Syngas cleanup system - low or high temperature and processes used to remove sulfur, nitrogen, particulates, and other compounds that may impact the suitability of the syngas for specific applications (i.e., turbine and fuel cell for electric power generation, hydrogen production, liquid fuel production, or chemical production). 

Petrov (1991) suggested the idea for using H S for production of hydrogen and sulfur in the electrolytic stage of the solar-wind-hydrogen energy systems (SWHES).
