1. A process for producing hydrogen gas from water, the process comprising: exposing a metal capable of generating hydrogen to an aqueous solution under supercritical conditions, or at a temperature of at least 200° C. and a pressure of at least the saturated vapor pressure of the water at said temperature; wherein said metal capable of generating hydrogen is Al, B, Mg, Si, Ti, Mn, Zn, or a combination thereof or their alloys thereof, and the metal is in solid state at the process temperature and has a coating of the oxide of the selected metal and/or alloy; wherein the coating is intact prior to the exposing of the reactive metal to the aqueous solution.
