Abstract: Electrolysis and catalytic thermochemistry are combined to decompose water while minimizing the energy demanded to accomplish the decomposition. The electrolyte is H2SO3 produced by supplying SO2 and the water to be decomposed to the electrolyzer. The H2SO3 is ionized and oxidized in the electrolyzer into SO4 and H ions and electrons. Hydrogen is derived from the negative electrode of the electrolyzer. The SO4 is combined with H to form H2SO4. The H2SO4 is removed from the electrolyzer to the thermochemical unit, concentrated and decomposed predominately into H2O, SO2 and O2. The SO2 is liquefied and thus separated from the O2 which is derived from the thermochemical apparatus. The liquid SO2 is vaporized and returned to the electrolyzer.
