What is compressed air energy storage?

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

Where can compressed air energy be stored?

The number of sites available for compressed air energy storage is higher compared to those of pumped hydro [, ]. Porous rocks and cavern reservoirs are also ideal storage sites for CAES. Gas storage locations are capable of being used as sites for storage of compressed air .

Is compressed air energy storage a feasible solution?

Storing intermittently generated renewable energy with compressed air energy storage (CAES) seems to have become more than a feasible solution in recent months, as several large-scale projects have been announced in the United States, Israel and Canada.

Are compressed air energy storage systems suitable for different applications?

Modularity of compressed air energy storage systems is another key issue that needs further investigation in other to make them ideal for various applications. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Can compressed air energy storage improve the profitability of existing power plants?

New compressed air energy storage concept improves the profitability of existing simple cycle, combined cycle, wind energy, and landfill gas power plants.

What are the options for underground compressed air energy storage systems?

There are several options for underground compressed air energy storage systems. A cavity underground, capable of sustaining the required pressure as well as being airtight can be utilised for this energy storage application. Mine shafts as well as gas fields are common examples of underground cavities ideal for this energy storage system.
