- The sulfur-iodine (SI) thermochemical water splitting cycle is one of promising hydrogen production
methods from water using high-temperature heat generated from a high temperature gas-cooled nuclear reactor
(HTGR). The SI cycle consists of three main units, such as Bunsen reaction, HI decomposition, and H2SO4
decomposition. The feasibility of continuous operation of a series of subunits for H2SO4 decomposition was
investigated with a bench-scale facility working at ambient pressure. It showed stable and reproducible H2SO4
decomposition by steadily producing SO2 and O2 corresponding to a capacity of 1 mol/h H2 for 24 hrs.
