Policy Frameworks Driving LDES Adoption

China’s regulatory landscape is actively shaping the future of long-duration energy storage. The newly introduced Carbon Peak Action Plan has opened major opportunities for vanadium flow batteries, aligning with national decarbonization targets. However, market dynamics are also being influenced by fiscal policies; a new consumption tax policy is expected to impact the vanadium flow battery sector starting from September 2026, prompting industry players to adapt their supply chain and pricing strategies accordingly.

Mega-Scale Compressed Air Energy Storage Breakthroughs

Beyond electrochemical storage, China is achieving remarkable milestones in mechanical long-duration systems. The Huaneng Jintan 2×350MW salt cavern compressed air energy storage project, recognized as the world's largest of its kind, has successfully completed the full unit startup of its second phase. This comprehensive test validates the operational stability of the equipment.

In another major achievement, the 300MW-class compressed air energy storage power station in Jiuquan, Gansu Province, successfully completed the first stage of gas injection in its underground No. 4 storage cavern. The test achieved a pressure of 12.63 MPa, setting a new world record for the highest pressure in artificial cavern storage, featuring the world's largest cross-section and highest volume.

Strategic Implications for the Global Market

These policy shifts and technological breakthroughs demonstrate China's comprehensive approach to energy storage. By simultaneously supporting diverse technologies like vanadium flow batteries and advanced compressed air systems, China is building a robust, multi-technology storage ecosystem. This dual approach not only secures domestic energy transition goals but also positions Chinese engineering and manufacturing firms at the forefront of the global market.

China’s new Carbon Peak Action Plan opens major opportunities for vanadium flow batteries, while new tax policies will reshape market dynamics from September 2026.
