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.

Disclosed are articles useful as the body of a container for containing gas under pressure, and containers which comprise the articles to which are affixed valves to control the flow of gas out of the container, wherein the articles comprise a hollow container body, having an external surface and having an opening through which gas can enter or leave the interior of the hollow container body; optionally but preferably a layer of fiber-reinforced polymer around the exterior of the container body, and an external layer of elastomer around and sealed to the external surface of the layer of fiber-reinforced polymer if present or else to the cylinder body.
