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. The compartmentalization network includes a plurality of thermally conductive elongate tubes positioned within the pressure vessel forming a coherent, tightly packed tube bundle providing a thermally conductive network between the hydrogen storage alloy and the pressure vessel. The hydrogen storage alloy is a non-pyrophoric AB.sub.2-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.

An apparatus and method for protecting a gas container interior, where an inlet and exhaust manifold include a port assembly attachable to a port of the gas container is provided, the gas container interior is exposed to sequential self-saturating surface reactions by sequential inlet of reactive gases via the port assembly and the port into the gas container interior, and reaction residue is pumped via the port and the port assembly out from the gas container.

A method and apparatus for applying a cladding layer to a surface of a component uses a cladding tool having a maximum reach less than the size of the surface. Geometry of the surface is segmented into a plurality of tessellated segments, each of which has a peripheral extent determined by a maximum reach of the cladding tool. A nominal tool subpath for each tessellated segment is generated, and then combined to generate a nominal tool path for depositing the cladding layer on the surface. The surface is clad using the nominal toolpath, including a process of adjusting the nominal tool path to an adjusted tool path that accounts for dimensions of the bead to be deposited by the tool to match an edge of the bead to be deposited with an edge of a previously deposited bead.

A method of coating a high-pressure fluid vessel comprises filling a high-pressure fluid vessel with a coating solution, draining the coating solution, and drying a remainder of the coating solution in the high-pressure fluid vessel. The coating solution may include a thermoplastic elastomer that is hard with a low glass transition temperature and a high melting temperature. Drying the remainder of the coating solution may form a food grade coating within the high-pressure fluid vessel.
