Financial analysis and design of compressed air energy storage

What is the design exergy efficiency and NPV of compressed air energy storage?

The design exergy efficiency and NPV of the system are 66.99 % and 12.25 M$. Compressed air energy storage (CAES) is one of the important means to solve the instability of power generation in renewable energy systems.

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.

When did compressed air energy storage start?

The first utility-scale compressed air energy storage (CAES) system, with a capacity of 280 MW, was established in 1978 at Huntorf in Germany. To date, one more large system of this type (McIntosh with a capacity of 110 MW in the USA in 1991) and facilities of an experimental nature have been commissioned .

What are the different types of compressed air energy storage systems?

After extensive research, various CAES systems have been developed, including diabatic compressed air energy storage (D-CAES), adiabatic compressed air energy storage (A-CAES), and isothermal compressed air energy storage (I-CAES) . A-CAES recovers the heat of compression, improving system efficiency by fully utilizing this heat.

What are the main components of a compressed air system?

The largest component in such systems is the storage medium for the compressed air. This means that higher pressure storage enables reduced volume and higher energy density.

What is compressed air used for?

Compressed air has been used for mechanical processes around the world since 1870. Buenos Aires, Argentina, used air pulses to move clock arms every minute. Starting in 1896, Paris used compressed air to power homes and industry.
