    The Mg-5-I thermochemical water-splitting cycle, consisting of (i) redox reaction of sulfur dioxide and iodine with magnesium oxide in aqueous phase, (ii) hydrolysis of magnesium iodide, (iii) thermal decomposition of magnesium sulfate and (iv) thermal dissociation of hydrogen iodide, was demonstrated on a laboratory scale by constructing an apparatus and by the repeated operations of chemical reactions and circulation of reactants through purely thermochemical processes below 1000 °C. With satisfactory performance of the system, 38 times of cycle operations were successfully repeated with roughly constant production of 0.3 liter of H2 and 0.15 liter of O2 per cycle. Surveys on the hydrogen production processes so far studied in this decade were also performed.
