Recently, the world's first 100 MW advanced compressed air energy storage national demonstration project was successfully connected to the grid in Zhangjiakou, Hebei. It is currently the world's largest single-unit and most efficient new compressed air energy storage power plant, with technology developed by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences.
It is reported that advanced compressed air energy storage technology is a long-time large-scale energy storage technology with great potential for development, with the advantages of large scale, low cost, long life, clean and non-polluting, unrestricted energy storage cycle, non-dependent on fossil fuels and geographical conditions.
