Abstract: Disclosed is a method for generating hydrogen. The method may include introducing water bubbles into a bottom region of a vessel containing molten aluminum allowing the water bubbles to rise within the molten aluminum, expanding as they rise. The method may further include collecting hydrogen, generated in a reaction between the water bubbles and the molten aluminum, from the vessel. Also disclosed is an apparatus for generating hydrogen that may include a vessel having an internal chamber for containing molten aluminum, at least one water inlet positioned at a bottom region of the vessel, at least one hydrogen outlet positioned at a top region of the vessel to and a heating element.
