In a major milestone for long-duration energy storage, China has activated the world’s largest liquid-air energy storage facility, known as the Super Air Power Bank. Built by China Green Development Investment Group (CGDI) in collaboration with the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences (TIPC-CAS), the facility is located in the Gobi Desert near Golmud city, in Qinghai Province.
The plant works by compressing and cooling air to –194°C, liquefying it, and storing it in specialized tanks. When electricity is needed, the liquid air expands over 750 times its original volume, driving turbines to generate power. Essentially, the project transforms air into an energy storage carrier under extreme cold.
