ABSTRACT:
A calcium-nickel compound, CaNi.sub.5, is used to store hydrogen at sub-atmospheric pressures. Charging of the calcium-nickel compound with hydrogen can be accomplished at sub-atmospheric as well as at high pressures. Stored hydrogen can be released from a valved vessel containing calcium-nickel by applicatin of a vacuum or by heating.
