The largest air energy storage project

What is a compressed air energy storage project?

A compressed air energy storage (CAES) project in Hubei, China, has come online, with 300MW/1,500MWh of capacity. The 5-hour duration project, called Hubei Yingchang, was built in two years with a total investment of CNY1.95 billion (US$270 million) and uses abandoned salt mines in the Yingcheng area of Hubei, China’s sixth-most populous province.

What is compressed air energy storage (CAES)?

The press conference was attended by nearly 200 industry leaders, experts, and media representatives, including: Compressed air energy storage (CAES) is a highly efficient large-scale energy storage technology that stores excess electricity by compressing air during off-peak hours and releases it to generate power during peak demand.

What is the energy storage industry white paper 2025?

The Energy Storage Industry White Paper 2025 reveals that global new energy storage installations reached 165.4 GW in 2024, with China contributing 43.7 GW of new capacity. Notably, compressed air energy storage (CAES) has emerged as the preferred grid-scale solution due to its long service life and superior safety characteristics.

Will China's energy storage capacity exceed 50 GW by 2030?

Industry projections indicate that China's compressed air energy storage capacity will exceed 50 GW by 2030, enabling annual CO₂ emission reductions of over 200 million tons - equivalent to shutting down 60 one-gigawatt coal-fired power plants - thereby providing robust support for building a new-type power system.
