Rongke Power (Dalian Rongke Power Co., Ltd.) is a China-based energy storage company specializing in vanadium redox flow battery (VRFB) technology. Headquartered in Dalian, Liaoning, the company traces its origins to research at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
Rongke Power designs and manufactures VRFB stacks, balance‑of‑plant components, and vanadium electrolyte, and supplies containerized systems from kilowatt to multi‑megawatt scale. Its solutions are used for grid peak shaving, renewable energy integration, microgrids, and industrial backup power. The company has participated in large stationary storage deployments, including the Dalian Liquid Flow Battery Energy Storage Peak‑shaving Power Station (planned 200 MW/800 MWh). Activities span electrolyte formulation and processing, system engineering, and project delivery. Flow battery technology enables high cycle life, scalable energy capacity, and inherent fire safety, characteristics relevant to long‑duration energy storage and the broader chemicals and materials value chain.
A new Iron-Vanadium flow battery supports gas operations, enhancing energy efficiency and reducing emissions, with a 25-year lifespan and adaptability to extreme climates.
