This study deals with solar hydrogen production from the two-step iron oxide thermochemical cycle (Fe3O4/FeO). This … exothermic steam hydrolysis of the reduced metal oxide (wustite) for hydrogen generation. Thermodynamic and experimental … investigations have been performed to quantify the performances of this cycle for hydrogen production. High-temperature decomposition …

Hydrogen, a promising and clean energy carrier, could potentially replace the use of fossil fuels in the transportation … sector. Currently, no environmentally attractive, large-scale, low-cost and high-efficiency hydrogen production process is … for CO2-free production of hydrogen. The method is environmentally friendly since it uses only water and solar energy …

Hydrogen is a kind of green fuel, and is considered as the substitute oil fuel for future. Although many of literature … plant for 1000 m3 hydrogen fuels. In where, the efficiencies of hydrogen fuel generation are 29.9%, 15.6%, 10.5% and 7 … respectively; and the ratio between the combustion heat of generated hydrogen fuels and the total electric energy consumption is …
