Abstract
A process is provided for the transport and storage of hydrogen by reversible sorption and containment within carbon-metal hybrid materials. The process comprises contacting a carbon-metal hybrid composition with a hydrogen-containing gas at conditions of temperature and pressure whereby the carbon-metal hybrid composition sorbs the hydrogen gas. The hydrogen that is sorbed in the carbon-metal composition is subsequently released by lowering the H2 pressure and/or increasing the temperature to levels which cause desorption of the hydrogen gas.
