Disclosed is a method of: providing a hydrogenated spcarbon allotrope, and releasing hydrogen gas from the carbon allotrope. The method may use an apparatus having: a vessel for containing the hydrogenated spcarbon allotrope, a fuel cell capable of using hydrogen gas a fuel, and a tube for transporting hydrogen gas from the vessel to the fuel cell. The carbon allotrope may be made by: providing a mixture of an spcarbon allotrope and liquid ammonia, adding an alkali metal to the mixture, and sonicating the mixture to form a hydrogenated form of the carbon allotrope. The hydrogenated carbon can be at least 3.5 wt % hydrogen covalently bound to the carbon.
