What are the disadvantages of a compressed air storage system?

With a rough estimate of 80% of U.S territory being geologically suitable for CAES, it has the potential to be a leading system within the storing of compressed air energy . One of the main disadvantages associated with this type of storage system is the need for the heating process to cause expansion.

Why do we need compressed air energy storage systems?

With excellent storage duration, capacity, and power, compressed air energy storage systems enable the integration of renewable energy into future electrical grids. There has been a significant limit to the adoption rate of CAES due to its reliance on underground formations for storage.

Why do compressed air energy storage systems have greater heat losses?

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.

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.

What is the design exergy efficiency and NPV of compressed air energy storage?

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.

Does air temperature affect system energy storage density?

The system energy storage density decreases with the increase in effectiveness of heat exchanger, which indicates that the positive impact of the increase in air temperature on the system output work enhancement is greater than the negative impact of the decrease in air pressure on the system output work reduction.
