Abstract
The paper described the results of the R and D which have been continued for 12 years on a new electric battery electric power storage system (load leveling function). The electric batteries for study were Na-S, Zn-Cl, Zn-Br, and redox type. Charge/discharge operation of 211 times was conducted of a pilot plant with a Na-S battery 1,000kW and 8-hour capacity. The overall efficiency of system was 71.5-76.0%, and the energy efficiency of battery was 86%. As a whole, the performance was able to be confirmed which can fulfil a developmental target. The system overall efficiency of 65.9% and battery efficiency of 76.1% were obtained. The experiment on battery life was carried out at plant together with the pilot operation. The mean life of Na-S battery was estimated at 800 cycles, and that of Zn-Br battery at 500-800 cycles. The effectiveness of the new electric battery electric power storage system was technically verified. For the future commercialization, studies on the following are needed: enhancement of reliability, easiness in maintenance/inspection, size reduction, cost reduction, etc. (NEDO)
