Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be , diabatic, , or near-isothermal.

What are the advantages of compressed air energy storage systems?
One of the main advantages of Compressed Air Energy Storage systems is that they can be integrated with renewable sources of energy, such as wind or solar power.
How does a compressed air energy storage plant work?
In times of excess electricity on the grid (for instance due to the high power delivery at times when demand is low), a compressed air energy storage plant can compress air and store the compressed air in a cavern underground. At times when demand is high, the stored air can be released and the energy can be recuperated.
What is compressed air energy storage?
Essentially, the term compressed air energy storage outlines the basic functioning of the technology. In times of excess electricity on the grid (for instance due to the high power delivery at times when demand is low), a compressed air energy storage plant can compress air and store the compressed air in a cavern underground.
What are the disadvantages of a compressed air storage system?
With a rough estimate of 80% of U.S territory being geologically suitable for CAES, it has the potential to be a leading system within the storing of compressed air energy . One of the main disadvantages associated with this type of storage system is the need for the heating process to cause expansion.
