  • Solar metal sulfate-ammonia based thermochemical water splitting cycle for hydrogen production
    Patent number: 8691068
    Abstract: Two classes of hybrid/thermochemical water splitting processes for the production of hydrogen and oxygen have been proposed based on (1) metal sulfate-ammonia cycles (2) metal pyrosulfate-ammonia cycles. Methods and systems for a metal sulfate MSO4—NH3 cycle for producing H2 and O2 from a closed system including feeding an aqueous (NH3)4SO3 solution into a photoctalytic reactor to oxidize the aqueous (NH3)4SO3 into aqueous (NH3)2SO4 and reduce water to hydrogen, mixing the resulting aqueous (NH3)2SO4 with metal oxide (e.g.
