Abstract

Abstract : Sumitomo Electric Industries, Ltd. (SEI) began the development of a redox flow battery (RFB) in 1985 and has delivered about 30 RFB systems so far. Since the establishment of the feed in tariff (FIT) system in Japan in 2012, a large amount of PV systems has been introduced and the need for energy storage batteries is rapidly rising. With the support of METI (the Ministry of Economy, Trade and Industry), a 15 MW/60MWh RFB system is currently operated by Hokkaido Electric Power Co., Inc. In this paper, the necessity of energy storage in Japan, the history of RFB development in SEI, some operation experiences of the RFB systems installed are reviewed. SEI is currently developing a new electrolyte using titanium and manganese ions and the development status is also reviewed.
