compressed air energy storage system cost

How can we model the cost of compressed air energy storage?

We can model the capex costs of Compressed Air Energy Storage from first principles in the model, by combining our models of compressor costs, storage facility costs and turbine costs. Our numbers also match top-down costs reported for past projects and technical papers into CAES.

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.

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.

Are caverns effective for compressed air storage?

While CAES has been demonstrated to deliver longer duration storage, its cost effectiveness is limited by the availability and design of the caverns used for compressed-air storage.

What is a CAES energy storage system?

CAES is dissimilar to other energy storage technologies, although it does share a feature with pumped storage hydropower: it comprises a series of subsystems, which include mature technologies, such as compressors, expanders, turbines, and heat exchangers.

How much storage can A CAES system provide?

In theory a CAES system could thus provide 24-hours of storage for as little 30-40c/kWh. These numbers are generally lower than for 24-hour storage in lithium ion batteries, comparable to redox flow batteries, but still higher-cost than the costs of 24-hour storage in thermal energy storage systems.
