China solidified its position as the world's largest market for advanced energy storage systems at the 13th Energy Storage International Summit, where industry analysts released the 2025 Energy Storage White Paper. The report reveals China accounted for 60% of global new installations in 2024, deploying 43.7 GW/109.8 GWh of cutting-edge storage capacity – marking the third consecutive year of global leadership.
A pivotal milestone was reached as advanced storage systems now represent over 56% of the nation's total installed capacity, overtaking traditional pumped hydro storage for the first time. Cumulative installations exceeded 75 GW by February 2024, cementing China's technological dominance in this critical energy transition sector.
Industry regulators confirmed breakthroughs across multiple storage technologies. While lithium-ion batteries remain mainstream, compressed air systems, flow batteries, and sodium-ion alternatives are gaining commercial traction. Emerging solutions like gravity-based storage and high-speed flywheels are also entering pilot phases, creating a diversified technological portfolio.
Envision Energy Storage stole the spotlight with its 8 MWh modular system containing 3,300 optimized battery cells. "Our cell-level innovations deliver 60% higher energy density than standard 5 MWh units," CEO Tian Qingjun told delegates. "The design cuts component counts by a third and slashes lifetime electricity costs by 40% through simplified maintenance."
Fire safety breakthroughs also made headlines. China Southern Power Grid Energy Storage unveiled nitrogen-based suppression systems eliminating environmentally harmful fluorinated chemicals. "Our patented fire control technology achieves 30% cost savings versus conventional solutions while meeting stringent environmental standards," said Chen Man, the company's R&D chief, noting the systems are already deployed at scale.
This expansion aligns with China's push to integrate renewable energy sources, with storage systems crucial for stabilizing power grids handling variable solar and wind inputs. Industry analysts predict the sector will require $12 billion annual investments through 2030 to maintain its growth trajectory.
