HYDROGEN ENERGY GENERATING SYSTEM

PROBLEM TO BE SOLVED: To provide a new conversion system for thermochemically producing biological crude oil and high purity hydrogen from natural gas or biomass, to provide a carrier for hydrogen, which is capable of being handled and regenerated, to provide a simple hydrogen generating system excellent in generating efficiency and to provide a system for generating high purity hydrogen which has excellent total energy balance. SOLUTION: Pure iron is finely pulverized or made into filament to increase the specific surface area, consequently to increase the energy density and is, for example, housed in a vessel under a vacuum or inert gas atmosphere. Hydrogen is efficiently generated by jetting and introducing high pressure high temperature steam in the vessel when using. The iron oxide used for the generation of hydrogen is regenerable and is stably burned by applying rich combustion, such as a combustion method of fluidized bed combustion, flameless combustion or pair burner using a combustion gas of fissile fuel such as natural gas or a (H2+CO) gas obtained from fuel such as biomass and causing the reduction reaction to enable low NOx combustion and not only the excellent reduction efficiency of iron oxide but also excellent total energy balance are attained.
