Contact AMES About This Technology

Technology Marketing SummaryThis is a cost-effective method for the production of pure hydrogen gas from ultra high capacity hydride solid materials.DescriptionResearchers at the Ames Laboratory have invented a cost-effective method for the production of pure hydrogen gas from ultra high capacity hydride solid materials. Pure gaseous hydrogen is obtained in the required quantities in excess of 5% hydrogen by weight at the required rate from a solid material in a solvent-free environment at ambient conditions.  This method has utility for energy conversion and production technologies that consume pure gaseous hydrogen as a fuel, such as in fuel cell technology, as well as for the storage, transportation, and production of hydrogen.BenefitsBenefits include that there is no need to heat the material, the produced hydroget if of high purity, and there is easy control over hydrogen output.

Method of production of pure hydrogen near room temperature from aluminum-based hydride materials
The present invention provides a cost-effective method of producing pure hydrogen gas from hydride-based solid materials. The hydride-based solid material is mechanically processed in the presence of a catalyst to obtain pure gaseous hydrogen. Unlike previous methods, hydrogen may be obtained from the solid material without heating, and without the addition of a solvent during processing. The described method of hydrogen production is useful for energy conversion and production technologies that consume pure gaseous hydrogen as a fuel.
