Description. CAES takes the energy delivered to the system (by wind power for example) to run an air compressor, which pressurizes air and pushes it underground into a natural storage area such as an underground salt cavern. At a later time, when there is electricity demand, the pressurized air is released back to the surface and heated.

Access huge amounts of energy when you need it. Compressed air energy storage (CAES) is a proven large-scale solution for storing vast amounts of electricity in power grids. As fluctuating renewables become increasingly prevalent, power systems will face the situation where more electricity is produced than it is needed to cover the demand.

The use of liquid air allows operating with an energy vector with a higher energy density if compared, for example, with the compressed air (150–250 Wh/kg vs. 30-60 Wh/kg) [15]. In an energy system based on a "liquid air economy" the liquid air has the main role to satisfy at the same time more than one energy need.
