TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The first element is chosen from silicon, alumina, activated carbon, metal hydrides, metal nitrides, or zeolites (preferably silicon). The second element is chosen from noble metals or transition metals (preferably palladium). The silicon atoms are capable of bonding to at least one hydrogen atoms, and the palladium atoms are bonded to the silicon atoms at locations capable of bonding to more than one hydrogen atoms. The porous matrix material is contained within a tank of a hydrogen storage system. Preferred Method: The silicon atoms are capable of bonding to at least one hydrogen atoms prior to the removing step, and the palladium atoms are bonded to the silicon atoms from which more than one hydrogen atoms were removed. The porous matrix material is formed and the hydrogen atoms are bonded to the atoms of the first element by etching a mass containing the first element. The removing step is performed by at least one of heating the porous matrix material, applying an electrical bias to the porous matrix material, and subjecting the porous matrix material to photon energy. The removing step is performed by heating the porous matrix material and is terminated based on time and temperature. The removing step is terminated based on the amount of hydrogen atoms released. The atoms of the second element are bonded to the atoms of the first element by subjecting the porous matrix material to an aqueous solution containing the second element. The method further involves discharging hydrogen from the porous matrix material; rehydrogenating the porous matrix material after the discharging step by gaseous or aqueous adsorption of hydrogen atoms; placing the porous matrix material within a tank of a hydrogen storage system; and discharging hydrogen from the porous matrix material and delivering the hydrogen to a power-generating device coupled to a power-consuming device. The rehydrogenating step is performed by contacting the porous matrix material with hydrogen gas or an aqueous acid solution. EXAMPLE - No suitable example given.
