A survey was made of metal hydrides for energy storage in the form of hydrogen, heat, 

 and a combination of both. Five intermctallic compounds were found to be promiing energy 

 storage vehicles. They werr: MgNi. Fel i, LaNi 5 , Lao jNi } , and Mischmetal Nis. The most 

 important property common to all these bvdrides is their ability to store large quantities of 

 hydrogen per cubic foot of the hydride: between 5 and 7 pounds per cui-ic foot, compared 

 to a liquid hydrogen density of about 4.4 pounds per cubic foot. Each of these compounds
