  • Publication number: 20100075183
    Abstract: One exemplary embodiment includes a modular hydrogen storage system including discrete modules constructed and arranged so the hydrogen can be delivered from a discrete module independent of the rest of the system.

  • Publication number: 20100061926
    Abstract: Auxiliary heating systems that can supply heat to a hydrogen storage material, which may comprise at least one hydridable material, located inside a hydrogen storage tank have been developed. These auxiliary heating systems involve the catalytic combustion of hydrogen and oxygen in a catalytic heater to produce heat and combustion products. The heat produced from the catalytic combustion may then be transferred, either indirectly or directly, to the hydrogen storage material to stimulate the release of additional desorbable hydrogen that may be stored in the at least one hydrdidable material.

  • Patent number: 7560028
    Abstract: Disclosed is a method that achieves water desalination by utilizing and optimizing clathrate hydrate phenomena. Clathrate hydrates are crystalline compounds of gas and water that desalinate water by excluding salt molecules during crystallization. Contacting a hydrate forming gaseous species with water will spontaneously form hydrates at specific temperatures and pressures through the extraction of water molecules from the bulk phase followed by crystallite nucleation. Subsequent dissociation of pure hydrates yields fresh water and, if operated correctly, allows the hydrate-forming gas to be efficiently recycled into the process stream.
