Many metal hydride systems have been proposed for energy storage purposes, but the one which seems to offer the best practical advantages is that based on the intermetallic compound FeTi. It is important that any FeTi alloy consists solely of the FeTi phase with the B2 (CsCl) crystal structure. Excess iron causes the formation of the Fe/sub 2/Ti Laves phase, which does not readily form a hydride. Excess titanium results in the presence of some Ti solid solution, which forms a highly stable hydride, locking up hydrogen in a nonrecoverable form. The presence of either of these phases reduces the efficiency of the hydride.
