350MW COMPRESSED AIR ENERGY STORAGE CAES PROJECT
100mw advanced compressed air energy storage system
The team started in 2017 and successfully developed a 100MW advanced compressed air energy storage technology with independent intellectual property rights, which solves the technical bottleneck problem of traditional compressed air energy storage systems relying on large gas storage chambers, relying on fossil fuels and low efficiency , the system design efficiency can reach 70.4%, which is about 20% higher than that of other existing international compressed air energy storage power stations, and the system scale is increased by an order of magnitude.
