There is a great deal of overlap between compressed air storage systems and pumped energy storage systems in terms of their working principles.

Thermal energy storage (TES) systems can store heat or cold to be used later, at different temperature, place, or power. The main use of TES is to overcome the mismatch between energy generation and energy use (Mehling and Cabeza, 2008, Dincer and Rosen, 2002, Cabeza, 2012, Alva et al., 2018).The mismatch can be in time, temperature, power, or

Illustration of a compressed air energy storage process. CAES technology is based on the principle of traditional gas t urbine plants. As shown in Figu re gas turbine, compressor and combustor. Gas with high temperature and high pressure, which is turn drives a generator to generate electricity [20,21]. For a CAES plant, as shown in Figure 5, there
The first adiabatic CAES project; the heat that appears during compression is also stored, and then returned to the air when the air is expanded. Construction will begin in 2013 in Staßfurt, a city in Sachsen-Anhalt, Germany (ADELE stands for the German acronym for adiabatic compressed air energy storage for electricity supply).
Solar energy is introduced to heat the high-pressure air from the air storage cavern to improve the turbine inlet air temperature. An ORC was introduced to recover the heat carried by the air-turbine exhaust.
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
The principle of ACAES is as follows; to charge the system electricity is used to drive compressors which generate hot compressed air. Since storing hot air is volumetrically inefficient, the excess thermal energy must first be removed from the hot air and stored in a separate thermal storage medium.
