6 FAQs about [Compressed air energy storage working structure and function]
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 determines the design of a compressed air energy storage system?
The reverse operation of both components to each other determines their design when integrated on a compressed air energy storage system. The screw and scroll are two examples of expanders, classified under reciprocating and rotary types.
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 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.
Are compressed air energy storage systems suitable for different applications?
Modularity of compressed air energy storage systems is another key issue that needs further investigation in other to make them ideal for various applications. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
Where will compressed air be stored?
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.
