Hydrogen production and storage in utility systems. Semiannual progress report, July 1975--December 31, 1975
A conceptual design of an electric energy storage system has been developed. Break-even cost data for introducing electric storage devices into the national energy system have been developed. Six materials were evaluated as substitutes for asbestos in the alkaline cell for use in 20 to 30 percent KOH at 150 to 160/sup 0/C. Three of these look promising. Tests were conducted on the largest hydride test bed (84 lb granular FeTi) to determine the length of time various flow rates could be sustained. In the Hydrogen Technology Advanced Components Test System, design specifications and cost goals based on small-scale tests and analysis have been established for the storage components. Design specifications and cost goals have also been established for electrolyzer components. Several compositions of the TiFe/sub y/MN/sub z/H/sub x/ type were investigated. These compositions show greatly reduced dissociation and association pressures which subsequently may reduce the electrolysis unit and hydride storage vessel costs. (LK)
