A technical analysis of energy storage devices and energy storage power systems for automobiles was performed. The goal was to determine which devices and power systems are most likely to provide credible alternatives to current automotive propulsion systems between now and the year 2000. This work results from a 15-month study undertaken by 4 national laboratories, 8 consulting firms, and over 50 individuals. Study panels examined electrochemical, mechanical, and chemical/thermal storage devices and selected the most promising ones. The panels then identified the research and development tasks necessary to successful development, determined the relative likelihood of overcoming technical barriers, and assessed the probable performance characteristics of future production devices. The key characteristics sought for each projected device were specific energy and specific peak power. For batteries, the relationship between specific power and specific energy was also determined. Since projected characteristics of future storage devices are uncertain, decision analysis techniques were used to project values both as a function of time and as a function of confidence level. Costs of the storage devices were also forecast. From a large number of candidate storage devices, the study panels selected seven batteries, three mechanical devices, three hydrogen storage devices and one thermal energy storage device for detailed evaluation. Various automotive power systems incorporating the selected energy storage devices were then analyzed.
