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.
Compared to compressed air energy storage system, compressed carbon dioxide energy storage system has 9.55 % higher round-trip efficiency, 16.55 % higher cost, and 6 % longer payback period. At other thermal storage temperatures, similar phenomenons can be observed for these two systems.
Compressed air energy storage systems enable the integration of renewable energy into future electrical grids. They have excellent storage duration, capacity, and power. However, there has been a significant limit to the adoption rate of CAES due to its reliance on underground formations for storage.
The “Energy Storage Grand Challenge” prepared by the United States Department of Energy (DOE) reports that among all energy storage technologies, compressed air energy storage (CAES) offers the lowest total installed cost for large-scale application (over 100 MW and 4 h).
A CAES (Compressed Air Energy Storage) system is an energy storage technology that is similar to other designs like humidifying compressed air storage (CASH), but follows its own unique principles.
Thermodynamic-economic performances of different systems are compared. Air is overall superior to carbon dioxide in compressed energy storage. Currently, working fluids for adiabatic compressed energy storage primarily rely on carbon dioxide and air. However, it remains an unresolved issue to which of these two systems performs better.
