Learn MoreDisadvantages of Compressed Air Energy Storage (CAES) One of the main disadvantages of CAES is its low energy efficiency. During compressing air, some energy is lost due to heat generated during compression, which cannot be fully recovered. This reduces the overall efficiency of the system.
Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
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 .
Compressed air energy storage systems may be efficient in storing unused energy, but large-scale applications have greater heat losses because the compression of air creates heat, meaning expansion is used to ensure the heat is removed [, ]. Expansion entails a change in the shape of the material due to a change in temperature.
Provides significantly high energy storage at low costs. Compressed air storage systems tend to have quick start up times. They have ramp rate of 30% maximum load per minute. The nominal heat rate of CAES at maximum load is three (3) times lower than combustion plant with the same expander.
The limitation of this type of storage system has to do with the storage volume being temperature resistant. This phenomenon occurs because at a lower pressure ratio, the air temperature remains higher. The temperature of the compressed air is usually greater than 250 °C at a pressure of 10 bar.
