Enerflow (Dalian) Energy Storage Technology Co., Ltd. is a research and development-driven company specializing in energy storage system integration. Founded in 2022 and headquartered in Weifang, China, the company focuses on providing safe and non-flammable energy storage solutions. Its business encompasses flow battery R&D, manufacturing, integration, sales, and maintenance. Enerflow has established a dual technology pathway, independently mastering both all-vanadium and iron-chromium flow battery technologies. The firm has also achieved in-house mass production of core components like proton exchange membranes, bipolar plates, and carbon felt.
The company's offerings include integrated, containerized flow battery systems that are standardized and modular for easy expansion, as well as customized stationary systems where power and capacity are designed separately to meet specific duration needs. Their water-based electrolyte is designed for safety and can operate in a wide temperature range, from -30°C to 65°C, with a projected 20-year lifespan and 100% recyclability. Enerflow's products are designed for the utility-scale market and can feature a depth of discharge of 100% and a lifetime of over 20,000 cycles. These systems play a crucial role in grid peak shaving, valley filling, and facilitating the integration of renewable energy sources.
Enerflow operates as a privately held, venture capital-backed company. It successfully completed a Series A funding round in May 2023 and a Series B round in January 2025, led by CICC Capital with participation from Shandong Finance Group and Binzhou State-Owned Capital Investment, among others. The company serves clients on the grid side, power generation side, and user side, providing comprehensive energy storage solutions. Enerflow's industrial presence includes R&D centers in Beijing and Weifang, and intelligent production lines in Weifang, Tongliao, Karamay, and Golmud.
