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.
Compressed air energy storage (CAES) is another efficient and cost-effective electricity storage system in this class (Arabkoohsar et al., 2016b). A main general disadvantage of this technology, regardless of its design, is its need for special geological site requirements ( Budt et al., 2016 ).

1.1. Compressed air energy storage concept. CAES, a long-duration energy storage technology, is a key technology that can eliminate the intermittence and fluctuation in renewable energy systems used for generating electric power, which is expected to accelerate renewable energy penetration [7], [11], [12], [13], [14].
Compressed Air Energy Storage technologies can be used for electricity balancing in future energy systems with a high share of fluctuating renewable energy sources such as e.g. wind power. In such systems, CAES plants will often operate on electricity spot markets by storing energy when electricity prices are low and producing
