CRITERIA FOR ENERGY STORAGE RESEARCH AND DEVELOPMENT

The U.S. Market for cars using stored, externally generated energy rather than stored fuel will depend largely upon the intended vehicle use. For short-range, multi-stop commercial applications over defined routes, electric vehicles may produce attractive life-cycle cost savings for fleet owners. By contrast, a sizeable penetration of the personal market for this type of car will probably await the development of vehicle characteristics, including first cost, that are competitive with those of gasoline-powered cars. The committee concluded that a competitive, electric, family vehicle capable of carrying four to six passengers and having a 200-mile range, 55-mph speed, and a competitive first cost will require at least 25 yr. of R&D. Batteries weighing no more than about 25 percent of the gross vehicle weight will be necessary for competitive performance of family cars. First-cost comparability will require that these advanced batteries have a specific energy cost considerably lower than that of the millions of automobile batteries now made each year. A vehicle combining storage with a conventional gasoline engine might achieve earlier market acceptance. For example, a flywheel, coupled with a small engine, might preserve the range and flexibility of the gasoline-powered vehicle while markedly improving mileage and reducing emissions. Such flywheel concepts need further development of establish their performance, safety; and cost characteristics.
