Thank you, Mr. Air, a netizen of CTOnews.com, for your clue delivery! CTOnews.com news on March 4, recently, the Institute of Engineering Thermophysics of the Chinese Academy of Sciences has made important progress in the research and development of advanced compressed air energy storage technology. Zhangjiakou International in Hebei Province, the first set of 100 megawatt advanced compressed air energy storage demonstration project compressor has passed the third party test with CNAS qualification, the test results show that the highest exhaust pressure is 100.333bar, the range of variable operating conditions is 18% Rue 118%, and the highest efficiency is 87.5%. Reach the international leading level.

Aerial view of ▲ 100 MW advanced compressed air energy storage national demonstration project compressed air energy storage has the advantages of large scale, long time, low cost, high efficiency, safety and environmental friendliness, and is one of the most potential large-scale energy storage technologies. The implementation plan for the development of new energy storage in the 14th five-year Plan takes 100 megawatt compressed air energy storage technology as one of the key directions of new energy storage core technology and equipment.

The compressor is one of the most important core components of the compressed air energy storage system. Its main function is to compress the atmospheric air to a high pressure state and store it in the gas storage device during energy storage. Complete the process of converting electrical energy into air pressure energy and thermal energy.

As previously reported by CTOnews.com, the Institute of Engineering Thermophysics of the Chinese Academy of Sciences has carried out the first research on compressed air energy storage technology in China since 2004. after 19 years of efforts, on the basis of successfully developing the first international 1.5MW and 10MW advanced compressed air energy storage national demonstration project, it has broken through the 100MW advanced compressed air energy storage key technology and built the world's first 100MW advanced compressed air energy storage national demonstration system. And successfully connected to the grid on September 30, 2022, setting a new milestone in the industry.

The first set of 100 MW advanced compressed air energy storage national demonstration project of Zhangjiakou International in Hebei Province is invested and built by Zhangbei Giant Energy Co., Ltd., a subsidiary of Giant Energy, and the technology provider is the Institute of Engineering Thermophysics of the Chinese Academy of Sciences. the equipment supplier is China Reserve National Energy (Beijing) Technology Co., Ltd., and the general contractor is the fourth Hydropower Bureau of China Electric Power Construction Group.
