The first attempt to conduct an overall analysis of the potential capital and life-cycle costs and energy efficiency of a passenger vehicle powered by an aluminum-air battery is presented. Hydrated alumina is the principal reaction product. Estimates of the operating characteristics of the vehicle were made on the basis of laboratory test results, performance-simulation-model test results, and hypotheses on the refueling. The LLL performance simulation model provided input data to the analysis on component weights, total vehicle weight, and fuel efficiency by simulating the SAE 227a(D) driving cycle for a five-passenger vehicle with an assumed power-to-weight ratio of 50 W/kg (0.03 hp/lb) and a range of 1600 km. The results indicated that the total vehicle weight would be 1854 kg, including a passenger and cargo load of 136 kg, and that the vehicular fuel efficiency would be 51 g/km. Cost and energy parameters were estimated on the basis of existing technology and resource pricing structures. Then the results of theses status-quo assessments were considered in the light of potential changes in technology and resource prices. The net cost to the consumer for aset of recycled replacement anodes was found to be $90 to $100. At the predicted fuel efficiency, the inferred fuel-related operating costs would be about 6 cents/km. The initial vehicle cost is estimated at $6650 and the life-cycle cost at 18 cents/ km. The aluminum-air-battery vehicle was found to be a serious contender for future transportation markets. 3 figures, 14 tables. (ERA citation 05:030739)
