China’s first 100 MW demonstration power plant with compressed air energy storage was connected to the grid in Zhangjiakou, Hebei Province.
The core equipment can generate more than 132 million kWh per year and provide power security for about 50,000 households at peak electricity consumption, save 42,000 tons of standard coal and reduce 109,000 tons of carbon dioxide emissions per year.
The technology of the demonstration project is provided by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences (hereinafter referred to as the Institute of Engineering Thermophysics), the investor is Giant Group Zhangbei Giant Energy Limited, and the equipment provider is China Storage State Energy (Beijing) Technology Co. Construction started in October 2020, complete equipment installation and system integration was December 2021.
Compressed air energy storage technology has the advantages of large scale, low cost, long life, clean and non-polluting, unlimited energy storage cycle, no dependence on fossil fuels and geographical conditions.
