Metal hydrides for energy storage applications. Technical note, 1 Jul 1973--30 Jun 1974
A survey was made of metal hydrides for energy storage in the form of hydrogen, heat, and a combination of both. Five intermetallic compounds were found to be promising energy storage vehicles. They were: MgNi, FeTi, LaNi/sub 5/, La(0.3)Ni/sub 5/, and Misch metal Ni/sub 5/. The most important property common to all these hydrides is their ability to store large quantities of hydrogen per cubic foot of the hydride: between 5 and 7 pounds per cubic foot, compared to a liquid hydrogen density of about 4.4 pounds per cubic foot. Each of these compounds was found to be able to store hydrogen under different experimental conditions, and each has its unique properties and handling characteristics. The survey was followed by a consideration of areas of possible useful applications. Several areas where metal hydrides can be of use are discussed in detail, including energy storage at remote bases and combat zones, underwater fuel storage, fuel and heat storage in closed system operations, and their use in heat pumps and automotive applications. Because of the ability of metal hydrides to supply hydrogen and absorb exhaust heat at the same time, and to deliver this absorbed heat during recharging where it can be used, they are useful in achieving better utilization of available energy.
