Massive Flow Battery and CAES Projects Advance
China continues to accelerate the deployment of long-duration energy storage across various regions, with significant milestones reached in both vanadium redox flow batteries and compressed air energy storage.
Flow Battery Milestones
In Yunnan province, the 300MW/1200MWh Yongren vanadium flow battery project is on track to achieve grid connection by the end of the year, supported by a dedicated 500MW/2GWh system integration production line. Meanwhile, the Lijiang Huaping shared energy storage station has successfully completed its supporting grid connection engineering. In Shanxi, Guohua Tuowei and Dalian Rongke Energy Storage signed a zero-carbon project agreement to develop independent storage and manufacturing. Additionally, the first phase of the Yingxian project has been successfully grid-connected.
Compressed Air Energy Storage Expansion
Compressed air storage is also seeing robust growth. The 100MW/600MWh Huanggang compressed air project in Hubei has completed its filing, featuring an 80,000 cubic meter underground gas storage solution. Furthermore, the massive 350MW/2100MWh Yingcheng compressed air project in Hubei has also completed filing, with construction planned to begin in June 2028.
The successful performance test of the Three Gorges Group's 10MW compressed air project marks the international first 10MW-level multi-source heat storage demonstration station fully possessing long-duration, large-capacity storage capabilities.
Moreover, the Inner Mongolia Erlianhot project highlights the dynamic nature of the market, as recent announcements indicate adjustments in EPC agreements, reflecting ongoing optimizations in project execution. The continuous pipeline of gigawatt-hour scale projects demonstrates the strong policy support and market demand for diverse long-duration technologies. These diverse projects underscore China's commitment to building a resilient, multi-technology infrastructure to support its rapidly expanding renewable energy capacity and grid stability.
