One function the Compressed Air Energy Storage (CAES) technology is very good at is load shifting. Load shifting is achieved by storing energy during periods of low demand and releasing the stored energy during periods of high demand. The NETL (2008) study notes that load shifting comes in several different forms.
Liquid air energy storage (LAES) uses air as both the storage medium and working fluid, and it falls into the broad category of thermo-mechanical energy storage technologies. The LAES technology offers several advantages including high energy density and scalability, cost-competitiveness and non-geographical constraints, and hence has …
Abstract. A compressed air energy storage (CAES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems, and is most appropriate for large-scale use and longer storage applications. In a CAES system, the surplus electricity to be stored is used to produce compressed air at high pressures.

The special thing about compressed air storage is that the air heats up strongly when being compressed from atmospheric pressure to a storage pressure of approx. 1,015 psia (70 bar). Standard multistage air compressors use inter- and after-coolers to reduce discharge temperatures to 300/350°F (149/177°C) and cavern injection air temperature …

Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity

Using compressed air for personal cooling will cost the example plant $2,500/yr on average. In comparison, using an electric fan for cooling will cost only about $150/yr. The electrical energy cost for personal cooling with compressed air is nearly 17 times higher than that of cooling using an electric fan.
2 Overview of compressed air energy storage. Compressed air energy storage (CAES) is the use of compressed air to store energy for use at a later time when required [41–45]. Excess energy generated from renewable energy sources when demand is low can be stored with the application of this technology.
ACAES is distinct from diabatic Compressed Air Energy Storage (CAES), where instead of thermal storage heat is provided by the combustion of fossil fuels. Two diabatic CAES plants have operated for over 30 years (Huntorf CAES, Germany, and MacIntosh CAES, USA). These two system types are illustrated below.
