|20100122747||Composite Structures for Hydrogen Storage and Transfer - Compressed hydrogen gas can be stored and transferred in hollow structures with walls that include at least one layer or interlayer of at least one porous metal, the purpose of the latter being to protect one or more surrounding layers from the damage that can be caused by diffusive flux of hydrogen gas. The masses of hydrogen gas that enter the layer(s)/interlayer(s) of the porous metal(s) are continuously or periodically removed from the interconnected pore space in the layer(s)/interlayer(s) of the porous metal(s) to ensure that the pressure(s) of the hydrogen gas remain(s) low—generally less than or equal to one atmosphere. When the structure that holds compressed hydrogen gas is a cylindrical pressure vessel, pipe or pipeline, a manufacturing technique known as “C-forming” can be used to create a wall that contains at least one layer or interlayer of at least one porous metal.||05-20-2010|
|20080233010||Testing Hydrogen Flux Through Solid and Liquid Barrier Materials - Apparatus and methods for testing the hydrogen-gas compatibilities, hydrogen-gas embrittlement susceptibilities, hydrogen-gas containment performances, and/or the hydrogen-gas pressure-cycling durabilities, of hollow enclosures (“test specimens”), with single-layer, double-layer, or multi-layer walls, composed of various barrier materials, are disclosed. Barrier materials include but are not limited to: carbon steel, stainless steel, copper, aluminum, a polymeric material (e.g., high-density polyethylene), and a liquid material (e.g., water, or an aqueous solution). The test gas is either high-purity hydrogen or a hydrogen-bearing gas mixture (e.g., hydrogen gas mixed with methane/natural gas and/or biomethane). A key piece of the testing equipment is an enclosure that surrounds the test specimen. Fabricated from high-strength, porous solid material (e.g., porous stainless steel), the enclosure (i) captures the hydrogen gas that diffuses through the wall(s) of the test specimen, and (ii) channels the flow of that gas toward a volume-calibrated reservoir.||09-25-2008|
