OverviewTypes of systemsTypesCompressors and expandersStorageEnvironmental ImpactHistoryProjects

Brayton cycle engines compress and heat air with a fuel suitable for an internal combustion engine. For example, burning natural gas or biogas heats compressed air, and then a conventional gas turbine engine or the rear portion of a jet engine expands it to produce work. Compressed air engines can recharge an electric battery. The apparently-defunct

Temperature and pressure variations within compressed air energy

In the present work, the thermodynamic response of underground cavern reservoirs to charge/discharge cycles of compressed air energy storage (CAES) plants was studied.

Performance analysis of an adiabatic compressed air energy storage

Adiabatic compressed air energy storage (A-CAES), as a branch of CAES, has been extensively studied because of its advantage of being carbon dioxide emission free. The round-trip efficiency (RTE) of A-CAES is approximately 70% [4]; further improving its efficiency can reduce the levelized cost of electricity (LCOE) and improve the market competitiveness.

Technology Strategy Assessment

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

Digital twin modelling for compressed air energy storage plants

The discharge cycle of a compressed air energy storage plant generally consists of (i) extracting pressurised air from the storage volume, (ii) heating the process air to a desired temperature, (iii) expanding the hot and pressurised air in a turbine and (iv) possibly repeating steps (ii) and (iii) several times. In the following, we refer to these steps as a "discharge unit"
