Liu et al. [ 45] calculated the energy density of compressed air to be 370 kJ/kg under the storage pressure of 20 MPa, which is much lower than that of diesel or gasoline. To ensure the continuous supply of compressed air during the operation, the power of the engine or the vehicle speed must be limited.

In general terms, Compressed air energy storage (CAES) is very similar to pumped hydro in terms of the large-scale applications, as well as the capacity of both in terms of output and storage. However, instead of pumping water from the lower reservoir to the higher reservoir as in the case with pumped hydro, CAES compresses ambient air in …
The 110 MW McIntosh plant can operate for up to 26 h at full power. The compressed air is stored in a salt cavern. A recuperator is operated to reuse the exhaust heat energy. This reduces the fuel consumption by 22–25% and improves the cycle efficiency from ∼42% to ∼54%, in comparison with the Huntorf plant.

As promising as compressed air appears as a storage medium, it does have some drawbacks. When air is compressed, it heats up. When it expands, it cools. Cold air isn''t as effective at producing power when it is run through a turbine, so before the air can be used, it needs to be heated, frequently using natural gas, which produces CO …
