【 Summary 】This summary collates key developments in China's vanadium flow battery and energy storage sector from June to July 2025, covering policy releases, project implementations, technical standard issuances, and SOE-private collaborations, highlighting industrial scaling and internationalization trends.
[pdf] While excess production capacity and a shrinking overseas demand for energy storage pose challenges, 11 leading companies have defied the odds. In the first 11 months of this year, they secured overseas orders totaling nearly 250GWh. Some companies have consistently clinched substantial deals.
[pdf] Unlike conventional batteries (which are typically lithium-ion), in flow batteries the liquid electrolytes are stored separately and then flow (hence the name) into the central cell, where they react in the charging and di.
[pdf] Chemical storage could offer high storage performance due to the high storage densities. For example, supercritical hydrogen at 30 °C and 500 bar only has a density of 15.0 mol/L while has a hydrogen density of 49.5 mol H2/L methanol and saturated at 30 °C and 7 bar has a density of 42.1 mol H2/L dimethyl ether. Researchers at EPFL and Kyoto University have created a stable hydrogen-rich liquid formed by mixing two simple chemicals. This breakthrough could make hydrogen storage easier, safer, and more efficient at room temperature.
[pdf] On the afternoon of October 30th, the world's largest and most powerful all vanadium flow battery energy storage and peak shaving power station (100MW/400MWh) was connected to the grid for power generation in Dalian, Liaoning.
[pdf] The official operation of this power station marks the successful application of immersion liquid cooling, a cutting-edge technology, in the field of new energy storage engineering, and plays a positive role in promoting China's overall energy security, stability, and green and low-carbon development.
