摘要： A hydrogen storage system includes a hydrogen storage alloy containment vessel comprising an external pressure containment vessel and a thermally conductive compartmentalization network disposed within the pressure containment vessel. The compartmentalization network creates compartments within the pressure vessel within which a hydrogen storage alloy is disposed. One or both of the compartmentalization network and the pressure vessel may be formed by a 3D printing process, such as by Selective Laser Melting (SLM) and/or Direct Metal Laser Sintering (DMLS). The hydrogen storage alloy is a non-pyrophoric AB2-type Laves phase hydrogen storage alloy having: an A-site to B-site elemental ratio of not more than 0.5; and an alloy composition including (in at %): Zr: 2.0-5.5, Ti: 27-31.3, V: 8.3-9.9, Cr: 20.6-30.5, Mn: 25.4-33.0, Fe: 1.0-5.9, Al: 0.1-0.4, and/or Ni: 0.0-4.0.

摘要： An apparatus in the form of a subterranean storage container configured to store a volume of a small molecular gas, such as hydrogen or methane. In some embodiments, a casing is arranged to extend into a subterranean formation. A top end of the casing is connected to a top cap structure. The top cap structure includes an adapter flange connected to an inner liner which extends within the casing and is separated therefrom by a circumferentially extending annulus. The annulus is configured to be filled with a fluid at a predetermined pressure. The fluid may be an uncompressible liquid such as propylene glycol. The small molecular gas is stored within an interior of the inner liner at a selected pressure, such as above 1000 pounds per square inch (psi).

摘要： Collapsible containers are an attractive alternative to surface-tension propellant management devices (PMDs) for handling cryogenic liquids, as the collapsible container comparatively may 1) allow higher expulsion flow rates than vanes and sponges, 2) significantly reduce operational complexity, and 3) thermally insulate the propellant from environmental heat leaks. Furthermore, while historical cryogenic collapsible containers suffered from the low ductility of polymer films at cryogenic temperatures, the technology disclosed herein shows that the incorporation of folded patterns into the collapsible container substantially increases the reusability of the cryogenic PMD.

摘要： A pressure vessel for storing fluid is disclosed. The pressure vessel includes a metallic liner comprising a cylindrical portion and a pair of ellipsoidal domes positioned at opposite ends of the cylindrical portion. Further, the pressure vessel includes a composite material wrapped over the cylindrical portion and the pair of ellipsoidal domes. The composite material is formed of a polymeric matrix reinforced with fibers, the composite material comprises of a combination of hoop layers and helical layers which are positioned in predetermined order with respect to each other. A hoop layer is wrapped over a cylindrical portion of the metallic liner of the pressure vessel and a helical layer is wrapped over both the cylindrical portion and the pair of ellipsoidal domes. The helical layer is wrapped on each of the pair of ellipsoidal domes in a manner that a helical angle is defined at an intersection between the cylindrical portion and the pair of ellipsoidal domes.
