  • Patent number: 8470292
    Abstract: The present invention relates to a hydrogen production method from water by using germanium oxide, more precisely a hydrogen and oxygen production method from water by thermochemical cycles using germanium oxide. The method of the present invention facilitates the production of hydrogen by multi-step thermochemical cycle using germanium oxide, so that it is characterized by that the thermochemical cycle is low temperature reaction and only water is consumed and other materials are not consumed but circulated.
