The compressed air storages built above the ground are designed from steel. These types of storage systems can be installed everywhere, and they also tend to produce a higher energy density. The initial capital cost for above- the-ground storage systems are very high.
Two main advantages of CAES are its ability to provide grid-scale energy storage and its utilization of compressed air, which yields a low environmental burden, being neither toxic nor flammable.
The technologies are battery energy storage systems (BESS), compressed air energy storage (CAES), flywheels and pumped hydro energy storage (PHES). Some local outlets have characterised this as a ''snub'' of green hydrogen technology and cited the ''disappointment'' of some energy storage market players at its omission.
Compressed Air Energy Storage (CAES) stores energy by compressing air and is suitable for large-scale energy storage applications. It helps balance supply and demand on the energy grid. Air is compressed during periods of low energy demand. When energy is needed, the compressed air is released to drive turbines, generating electricity.
