Dynamic tests and modeling studies were made on the chemi-cal-energy-storage portion of an electrical energy conversion and storage system proposed for leveling the load of an electric utility company. Hydrogen in the form of a metal hydride was used as the energy storage medium. The concept utilizes off-peak power to produce hydrogen by electrolyzing water, storing the hydrogen as iron-titanium hydride, FeTiH, and subsequently re¬leasing the hydrogen to a fuel cell where the reaction with air generates electrical power.
