Abstract
A non-pyrophoric AB2-type Laves phase hydrogen storage alloy and hydrogen storage systems using the alloy. The alloy has an A-site to B-site elemental ratio of no more than about 0.5. The alloy has an alloy composition including about (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. The hydrogen storage system has one or more hydrogen storage alloy containment vessels with the alloy disposed therein.
