Sumitomo Electrical, a unit of Japanese conglomerate Sumitomo Corp., disclosed the outcomes of exams of a vanadium redox circulate battery system it deployed in 2017 at a facility owned by US utility SDG&E in Bonita, close to San Diego, California.
Sumitomo stated outdoors consultants are accumulating information from the 2MW/8MWh Redox Stream Battery Demonstration Mission till the tip of 2021. Preliminary evaluation carried out in December revealed that the battery system has achieved 99% working effectivity. price within the final yr of the undertaking. Sumitomo believes that the battery system has the potential to keep up a capability price of 90% or extra for 20 years within the electrical energy market.

Specialists gave a score of two.6 out of three to the general outcomes of the undertaking. Sumitomo stated the demonstration undertaking efficiently demonstrated the enterprise feasibility of utilizing storage battery applied sciences for electrical energy market bidding and the essential capabilities of redox circulate batteries in microgrid purposes. The battery operates inside a microgrid, supplying electrical energy to 66 residential and business clients for about 5 hours.
Sumitomo and SDG&E are deploying a microgrid by integrating the battery into {the electrical} distribution community. This setup options the twin operation functionality of the battery, which permits it to serve the wholesale electrical energy market beneath regular circumstances and supply grid resilience throughout emergencies. The battery additionally has a black begin functionality, which allows it to start out and proceed service even after an entire energy outage.
The undertaking acquired help from Japan’s New Vitality and Industrial Expertise Improvement Group (NEDO) and California’s GO-Biz. The event of the undertaking began in 2015. Sumitomo has already deployed 37 redox circulate battery methods in a number of international locations, with a complete capability of 47 MW/162 MWh.
