6 FAQs about [The current status of the development of air energy storage devices]

How can compressed air energy storage improve the stability of China's power grid?

The intermittent nature of renewable energy poses challenges to the stability of the existing power grid. Compressed Air Energy Storage (CAES) that stores energy in the form of high-pressure air has the potential to deal with the unstable supply of renewable energy at large scale in China.

What is diabatic compressed air energy storage (D-CAES)?

Since the compression heat is wasted by air cooling, and fuel combustion is required to heat the compressed air at the inlet of the expander, it is defined as diabatic compressed air energy storage (D-CAES). The cycle efficiency of D-CAES is around 50% . Fig. 1. Different types of CAES (a) diabatic CAES and (b) adiabatic CAES.

Is there a future for compressed air storage?

There are two large scale compressed air storage plants are in operation and their success encourages the technology development. A number of pilot projects in building new generation of CAES are on-going. All the projects have demonstrated the difficulties in financial investment.
