Method for producing hydrogen

A process for causing a catalytic reaction of aluminum and water for producing hydrogen gas, comprising the steps of;

• providing an aqueous solution in a vessel, said aqueous solution containing a portion of NaOH and a portion of water;
• introducing a portion of aluminum in said aqueous solution;
• reacting said portion of aluminum with said portion of water, thereby producing hydrogen gas;
• and
• while maintaining substantially constant said portion of NaOH in said vessel, adding additional portions of water and additional portions of aluminum in said vessel according to a rate of consumption of said aluminum and said water in said step of reacting.

A process for simultaneously producing hydrogen gas and alumina, comprising the steps of;

• providing an aqueous solution in a vessel, said aqueous solution containing between 0.26 M and 19 M NaOH;
• introducing aluminum is said aqueous solution;
• reacting aluminum with water in said aqueous solution and generating hydrogen gas and alumina;
• and
• recovering said hydrogen gas and said alumina.
