Despite the technology of compressed-air vehicles being environmentally friendly and economically viable, it has certain severe drawbacks, such as a low energy density. Furthermore, compressed air is held at extremely high pressure in the main tank, which is controlled with a valve for providing the air at the engine''s operating pressure.

1. Introduction. Compressed air energy storage (CAES) is an energy storage technology whereby air is compressed to high pressures using off-peak energy and stored until such time as energy is needed from the store, at which point the air is allowed to flow out of the store and into a turbine (or any other expanding device), which

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
