Abstract: The paper deals with the technical and economic comparison of methods of hydrogen production by means of water electrolysis and hydrothermal oxidation of aluminum. Technological chains required for the realization of these methods are analyzed, costs of equipment and maintenance are evaluated. It is demonstrated that for the large-scale production of hydrogen aluminum-water technology is competitive with electrolysis option under the cost of electricity up to 0.02 USD/kWh. The conditions of the maximal feasibility of hydrogen generation using aluminum are specified. Metal hydride thermal sorption compressor is proved to be the best device to commercialize the generated hydrogen. Its application lowers the cost of compression 5–10 times.
