What is compressed air energy storage (CAES)?
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.
How does a compressed air energy storage system work?
The performance of compressed air energy storage systems is centred round the efficiency of the compressors and expanders. It is also important to determine the losses in the system as energy transfer occurs on these components. There are several compression and expansion stages: from the charging, to the discharging phases of the storage system.
What is the theoretical background of compressed air energy storage?
Appendix B presents an overview of the theoretical background on compressed air energy storage. Most compressed air energy storage systems addressed in literature are large-scale systems of above 100 MW which most of the time use depleted mines as the cavity to store the high pressure fluid.
Where can compressed air energy be stored?
The number of sites available for compressed air energy storage is higher compared to those of pumped hydro [, ]. Porous rocks and cavern reservoirs are also ideal storage sites for CAES. Gas storage locations are capable of being used as sites for storage of compressed air .
What is a compressed air storage system?
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.
What determinants determine the efficiency of compressed air energy storage systems?
Research has shown that isentropic efficiency for compressors as well as expanders are key determinants of the overall characteristics and efficiency of compressed air energy storage systems . Compressed air energy storage systems are sub divided into three categories: diabatic CAES systems, adiabatic CAES systems and isothermal CAES systems.
