China's Flow Battery Technology Has Already Established A Leading Advantage in The World.

In 2024, China saw a leapfrog growth in the installed capacity of flow batteries. The newly connected flow battery energy storage projects amounted to 0.81 GW/3.23 GWh, marking a tenfold increase compared to 2023. This signifies a crucial step for the flow battery industry transitioning from '1' to 'N', entering the commercial development stage.

Sun Fulei, executive president of Hebei Province Vanadium Titanium Industry Association, stated that Hebei Province places great emphasis on the development of energy storage industry. It was the first to release a long-term work plan supporting the development of new energy storage technologies, leading the nation in terms of top-level design, technology application, market mechanisms, and installed capacity. A number of key projects in the all-vanadium flow battery industrial chain are currently under planning and construction, providing a broad space for industry development.

Sun Fulei believes that breakthroughs in the industry require strengthening technological sharing, industrial collaboration, and standardization. Since its establishment, the Hebei Province Vanadium Titanium Industry Association has always regarded promoting the development of all-vanadium flow batteries as a significant mission. It has achieved remarkable results in promoting technological innovation and industrial collaboration, and is willing to join hands with various sectors of society to gather industrial

Sun Fuli pointed out that as an important base for vanadium-titanium resources in our country, Hebei Province has unique advantages in developing flow battery industries. Currently, Hebei Province already possesses a complete full-vanadium flow battery industrial chain, showing significant strengths in industry control and safety support. In terms of high-purity vanadium production, it boasts

China's flow battery industry is primarily dominated by vanadium redox flow batteries, including iron-chromium flow batteries, zinc-iron flow batteries, and aqueous organic flow batteries. In the flow battery energy storage projects that were tendered and implemented in 2024, the capacity of vanadium redox flow battery projects reached 973.45 MW/4071.35 MWh, with several GWh-scale projects, totaling over 3.485 billion yuan in winning bids, accounting for 96.67% of the total capacity. Iron-chromium flow battery energy storage projects amounted to 40 MW/80 MWh, while zinc-iron flow battery energy storage projects reached 20 MW/40 MWh, and aqueous organic flow battery energy storage projects were 5.2 MW/20.4 MWh. From January to May this year, long-duration energy storage projects with durations of 4 hours or more reached 1.18 GW/5.23 GWh, indicating a favorable development trend for the industry. It is understood that China's flow battery industry has basically established an agglomerative development pattern. A 'Dalian-Liaoyang-Shenyang' flow battery industrial belt led by technology and leading companies has been formed, along with a Beijing-Hebei industrial hub integrating resources and technology, an eastern coastal industrial cluster driven by dual forces of research and manufacturing, a Sichuan manufacturing base supported by resources and driven by technology, and an industrial system co-developing with cities and resources. The industry matrix includes leading enterprises such as Dalian Rongke Power Storage Technology Development Co., Ltd., Shanghai Electric Energy Storage Technology Co., Ltd., Sichuan Weili Energy Co., Ltd., Flow Battery Energy Storage Technology Co., Ltd., Zhejiang Xingchen New Energy Technology Co., Ltd., Dalishi Energy Storage Technology Hubei Co., Ltd., Suqian Times Energy Storage Technology Co., Ltd., Sichuan Development XinXin Vanadium Energy Technology Co., Ltd., Suzhou Kerun New Materials Co., Ltd., Liaoning Jingu Carbon Material Co., Ltd., and Jiangyou Runsheng Graphite Felt Co., Ltd., which are continuously enhancing their international competitiveness. Sichuan's flow battery industry has developed a technology-driven trend supported by abundant resources and has become a world-class manufacturing base. With 87% of China's vanadium resources located in Sichuan, it has established a complete industrial chain from vanadium ore mining, extraction, electrolyte production, key material manufacturing for vanadium redox flow batteries, to system integration, ensuring stable operation of the industry through abundant resource supply and key material production capabilities."
