A gas-loading and packaging system is provided for loading a material used in a hydrogen fuel cell with gas and packaging the material in a sealed container. The gas may comprise a hydrogen gas or other gas. The material may, for example, comprise zeolite. The material is loaded with gas by exposing the material to the gas under high pressure and a cryogenic temperature of about 93 Kelvin or lower. When the material is exposed to gas under pressure and at cryogenic temperature, the gas absorbs into or adsorbs onto the material. The mass of the material is continuously monitored and used to determine when the material is loaded with the desired amount of gas. After the material is loaded with gas, high pressure and cryogenic temperature is maintained while the material is packaged and sealed in a cryogenically cooled container.

A method for creating hydrogen gas comprising; providing a first quantity of hydrogen dioxide to a preparation chamber. heating a quantity of the hydrogen dioxide within a first sealed pressurized chamber, wherein the hydrogen dioxide enters a gaseous state, directing, the gaseous hydrogen dioxide into a reaction chamber, initiating a reaction between the hydrogen dioxide and a quantity of alkali fragments within a reaction chamber to produce hydrogen and an alkali hydroxide, separating the hydrogen gas from the alkali hydroxide, and recovering the hydrogen gas.
