California has set a high goal for renewable energy introduction, such as by establishing the State Law SB 100 to cover 100% of the electricity in the state with energy that does not emit greenhouse gases by 2045. NEDO and Sumitomo Electric Industries will start a demonstration project where a stationary Redox Flow Battery (RF Battery) is tested for its power adjustment capabilities such as frequency adjustment required by the electric wholesale market and energy supply based on energy trading.
