NOVELTY - The method comprises selecting a vessel without water consisting of a first holding area for a metallic ingredient that releases hydrogen when reacting with water and a second holding area for an inorganic hydride that releases hydrogen when reacting with water, placing the metallic ingredient in the first holding area and the inorganic hydride in the second holding area within the vessel, keeping the metallic ingredient and inorganic hydride separate until the reaction with water is desired for the production of hydrogen, and adding an alkali metal-based compound to the inorganic hydride.    USE - The method is useful for producing hydrogen from water including tap water, reclaimed water, industrial grade water and sea water, where the hydrogen is useful: in polymer electrolyte membrane fuel cell; in turbines, internal combustion engine and diesel engines; in high-power density portable and miniature power systems for electronics and uninterrupted power supply units; and for space and military applications including soldier power supply, unmanned aerial vehicles and air-independent propulsion for submarines.    ADVANTAGE - The method ensures simple, efficient, safe and economical production of hydrogen at ambient conditions with high purity (99.99%) and energy conversion efficiency and enhanced performance characteristics such as specific energy and power density and without any harmful contaminants such as carbon monoxide, hydrogen sulfide, ammonia and unsaturated and aromatic hydrocarbons.    DETAILED DESCRIPTION - The method comprises selecting a vessel without water consisting of a first holding area for a metallic ingredient that releases hydrogen when reacting with water and a second holding area for an inorganic hydride that releases hydrogen when reacting with water, placing the metallic ingredient in the first holding area and the inorganic hydride in the second holding area within the vessel, keeping the metallic ingredient and inorganic hydride separately until the reaction with water is desired for the production of hydrogen, adding an alkali metal-based compound to the inorganic hydride to stabilize the inorganic hydride, adding water to the vessel to cover the first holding area with the metallic ingredient-transition metal combination and the second holding area with the inorganic hydride, adding a transition metal compound from groups VIII and IB to the metallic ingredient, and collecting hydrogen released from the decomposition of water in a synergistic aqueous reaction of metallic ingredient and inorganic hydride at ambient conditions of temperature and pressure. The transition metal compound catalyzes the synergistic aqueous reaction of the metallic ingredient and the inorganic hydride. The metallic ingredient is IIA-IVA and VIII alloys. The inorganic hydride is inorganic complex metal hydrides.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of an apparatus for hydrogen production.
