The incorporation of Compressed Air Energy Storage (CAES) into renewable energy systems offers various economic, technical, and environmental advantages.
In a Compressed Air Energy Storage system, the compressed air is stored in an underground aquifer. Wind energy is used to compress the air, along with available off-peak power. The plant configuration is for 200MW of CAES generating capacity, with 100MW of wind energy.
The benefits and limitations of compressed air energy storage (CAES) include various socio-economic advantages. These advantages include: However, CAES also encounters challenges related to its economic feasibility and operational constraints when compared to alternative energy storage methods.
In low demand periods, energy is stored by compressing air in an air tight space (typically 4.0~8.0 MPa) such as an underground storage cavern. To store energy, air is compressed and sealed in the space. To extract the stored energy, compressed air is drawn from the storage vessel, mixed with fuel, and then combusted. The expanded air is then passed through a turbine.
Compressed air energy storage may be stored in undersea caves in Northern Ireland. In order to achieve a near- thermodynamically-reversible process so that most of the energy is saved in the system and can be retrieved, and losses are kept negligible, a near-reversible isothermal process or an isentropic process is desired.
CAES efficiency depends on various factors, such as the size of the system, location, and method of compression. Typically, the efficiency of a CAES system is around 60-70%, which means that 30-40% of the energy is lost during the compression and generation process. What is the main disadvantage of compressed air-based 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.
