San Diego Flow Battery

Does Sumitomo Electric have a vanadium redox flow battery?

Sumitomo Electric has been proceeding with a vanadium redox flow battery (VRFB) pilot project in coordination with San Diego Gas & Electric, stemming from a partnership between Japan's New Energy and Industrial Technology Development Organization (NEDO) and the California Governor's Office of Business and Economic Development (GO-Biz).

Can vanadium redox flow battery storage improve grid management?

Sumitomo and SDG&E’s 2MW/8MWh redox flow battery system. Credit Sumitomo Utility San Diego Gas and Electric (SDG&E) and Sumitomo Electric (SEI) have launched a 2MW/8MWh pilot vanadium redox flow battery storage project in California to study how the technology can reliably integrate renewable energy and improve flexibility in grid management.

Does Sumitomo have a 99% redox flow battery?

Sumitomo says that its 2MW/8MWh vanadium redox flow battery achieved a 99% operating rate at San Diego Gas & Electric's (SDG&E) facility in California. The battery is expected to retain a capacity rate of 90% or more for 20 years in the electricity market.

What is a flow battery?

Flow batteries are an alternative battery type in the industry (Figure 21). Flow batteries consist of two large separate tanks containing a liquid electrolyte. The battery operates by pumping the two separate electrolytes through a cell to allow ion transfer between the two liquids. A membrane prevents the two liquids from mixing.
