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.
Compressed air energy storage (CAES) technology stands out among various energy storage technologies due to a series of advantages such as long lifespan, large energy storage capacity, and minimal environmental impact .
Assessment of design and operating parameters for a small compressed air energy storage system integrated with a stand-alone renewable power plant. Journal of Energy Storage 4, 135-144. energy storage technology cost and performance asse ssment. Energy, 2020. (2019). Inter-seasonal compressed-air energy storage using saline aquifers.
Compressed air is stored in underground caverns or up ground vessels , . The CAES technology has existed for more than four decades. However, only Germany (Huntorf CAES plant) and the United States (McIntosh CAES plant) operate full-scale CAES systems, which are conventional CAES systems that use fuel in operation , .
During discharging, the high-pressure air is heated and then enters the expander to generate electricity . After extensive research, various CAES systems have been developed, including diabatic compressed air energy storage (D-CAES), adiabatic compressed air energy storage (A-CAES), and isothermal compressed air energy storage (I-CAES) .
The design exergy efficiency and NPV of the system are 66.99 % and 12.25 M$. Compressed air energy storage (CAES) is one of the important means to solve the instability of power generation in renewable energy systems.
