About Guorun Energy Storage

Established in June 2020, Shanxi Guorun Energy Storage Technology Co., Ltd. operates as a specialized manufacturer of all-vanadium flow battery equipment and core membrane materials for the energy storage sector. The company is strategically positioned within the electrochemical energy storage market, focusing on solutions that offer an alternative to mainstream lithium-ion batteries. Its business model centers on the production and sale of these core components and integrated systems to clients in renewable energy, grid services, and industrial sectors requiring long-duration energy storage. Revenue is generated through direct sales of its products and providing comprehensive energy storage solutions.

The company's founder, Meng Qing, holds a postdoctoral degree from Tsinghua University and serves as the chairman. His technical background has guided the company's focus on research and development in the flow battery space. Guorun Energy Storage's primary offerings are all-vanadium flow battery products and perfluorinated ion membranes. The batteries are noted for their safety, as the vanadium-based aqueous electrolyte is not prone to combustion, and for their long operational lifespan, which can exceed 20 years and 15,000 charge-discharge cycles. A key feature is the scalability of capacity; energy storage can be increased simply by enlarging the electrolyte storage tanks, making it suitable for long-duration applications of four hours or more. The company has developed single stack modules in various specifications, including 2.5KW, 5KW, 10KW, 20KW, and 30KW units. Additionally, Guorun produces perfluorinated ion membranes, a critical component for flow batteries, electrolyzed water for hydrogen production, and hydrogen fuel cells, using self-developed graphene materials and proprietary welding processes.

Significant milestones include the completion of an Angel round of over 50 million RMB in August 2022 and a Series A funding round of nearly 200 million RMB in June 2023 to expand production capacity. The company has established an automated production line for perfluorinated ion membranes with an annual output of 100,000 square meters and a 100MW intelligent production line for vanadium flow batteries. In November 2023, Guorun signed an agreement for a 1GWh vanadium flow battery manufacturing project in Wenzhou. The company has also secured contracts with major players like China Nuclear Power and State Power Investment Corporation (SPIC), with orders exceeding 200 million RMB in 2023. In April 2025, it entered a strategic cooperation with China General Nuclear Power Group to jointly develop wind, solar, and new energy storage projects.
