China's LDES Sector Sees Massive Project Mobilization

China's long-duration energy storage (LDES) sector is experiencing a wave of massive project mobilizations, with a strong emphasis on vanadium redox flow batteries (VFB) and hybrid storage systems. Recent developments highlight the country's aggressive push to scale up grid-side energy storage to support its expanding renewable energy capacity.

Gigawatt-Scale Hybrid Storage Projects

Several monumental projects have recently reached critical milestones. In Shanxi Province, the Jinneng Holding Group officially commenced construction on an 820MW/3280MWh energy storage project. Notably, this massive facility includes 80MW of lithium iron phosphate and 20MW of vanadium flow battery systems, showcasing a hybrid approach. Similarly, in Jilin Province, a 200MW/800MWh grid-side formulating independent energy storage station has completed its filing, utilizing a hybrid technology of vanadium and lithium batteries.

The integration of vanadium flow batteries with lithium-ion systems in these mega-projects highlights a strategic shift towards optimized, long-duration hybrid storage solutions.

EPC Awards and Manufacturing Expansion

The procurement phase for these projects is also moving rapidly. In Yantai, the EPC bidding for a 350MW/750MWh hybrid storage project (combining lithium iron phosphate and VFB) has announced its winning candidate, with the winning bid price at approximately 0.97 RMB/Wh. Meanwhile, in Yunnan, a 200MW/800MWh pure vanadium flow battery storage station project has released its winning candidate announcement.

Supporting this deployment wave is a surge in manufacturing capacity. A major investment of 1.2 billion RMB has been secured to establish a 2GW vanadium flow battery research and production base in Nanyang. This comprehensive expansion across project development, EPC contracting, and manufacturing underscores China's commitment to dominating the global LDES supply chain and deployment.
