The city of Zhangjiakou in the north of China has one of the most advanced and one of the largest compressed air storage systems connected to the network today. The Chinese Academy said that riozotal d etIFES It emerged with an eye to energy reform in the country – by 2030, such systems already account for 25% of all energy storage in China.
The storage has a capacity of 100 MW and can store up to 400 MWh of energy. Details of the drive device are not disclosed, however, it is known that this is a complex complex project. It utilized cutting-edge developments in supercritical heat and technologies to control the compression and expansion of gases under high pressure.
The main advantage of the Chinese system is in the design efficiency, which is 70.4%. This is a world record, since the d d i d i d i n n o n o degree is not higher than 42-50%, and in the SVES, the power facility in Zhangjiaou can supply 132 GWh of electricity per year, which is quite likely already from houses. This will save 42 thousand tons of coal and reduce carbon dioxide emissions by 109 thousand tons. tons.
