    Abstract: A method of generating a high-level vacuum comprises evacuating a chamber having a substantially-pure gas therein to a medium-level vacuum, and freezing the residual gas to generate the high-level vacuum within the chamber. Impurities, such as atmospheric air, may be purged from the chamber by evacuating the chamber to a medium level vacuum (e.g., around 10−2 Torr) and subsequently filling the chamber with the gas. This purging process may be repeated multiple times to decrease the level of impurities in the gas filling the chamber. The substantially-pure gas may have an impurity-level of less than approximately 100 PPM and may comprise carbon-dioxide, although the scope of the invention is not limited in this respect. The medium level vacuum may range between approximately 1×10−2 Torr and 5×10−2 Torr allowing the use of a roughing pump, and the high-level vacuum may range between approximately 1×10−5 and 1×10−8 Torr.

    Abstract: A hydrogen storage and delivery system is provided having an orifice pulse tube refrigerator and a liquid hydrogen storage vessel. A cooling system, coupled to the orifice pulse tube refrigerator, cools the vessel and abates ambient heat transfer thereto in order to maintain the liquid hydrogen in the vessel at or below its saturation temperature. Hydrogen boil-off, and the necessity to provide continuous venting of vaporized hydrogen are minimized or avoided. In a preferred embodiment, the hydrogen storage vessel has a toroidal shape, and the pulse tube refrigerator is a two stage pulse tube refrigerator and extends within a central void space defined at the geometric center of the toroidal storage vessel. Also in a preferred embodiment, the cooling system includes first and second thermal jackets, each having a substantially toroidal shape and enclosing the storage vessel, wherein each of the thermal jackets is thermally coupled to one of the first or second stages of the pulse tube refrigerator in order to cool the vessel and to abate ambient heat leak thereto. The hydrogen storage and delivery system is particularly suitable for use in vehicles, such as passenger automobiles.

    Abstract: A high pressure vessel assembly includes a central pivot tank and coaxial or concentrically disposed tanks for liquid or gas storage with or without gaseous phase cooling. The pivot tank comprises a cylindrically shaped wall having torus-shaped ends and is surrounded by an annularly shaped internal tank having internal and external walls with the former being joined to the pivot tank by bands adjacent the tank ends to provide an intermediate chamber. A larger diameter external tank likewise of annular configuration, surrounds the internal tank and is also joined thereto in a manner providing an intermediate chamber. A fitting projecting from the ends of all three tanks at one end of the assembly permits filling or emptying of the respective tanks while a separate discharge pipe projecting from the internal and external tank ends communicates with the two chambers to carry away any fluid leaking from the juxtaposed peripheral walls of the tanks.
