The intention of this paper is to give an overview of the current technology developments in compressed air energy storage (CAES) and the future direction of the technology development in this area.
What is the exergy efficiency of a compressed air energy storage system?
In the exergy analysis, the results indicate that the exergy efficiency of the compressed air energy storage subsystem is 80.46 %, which is 16.70 % greater than the 63.76 % of the reference compressed air energy storage system, showing that the system integration can decline the exergy loss.
What is the value of compressed air energy storage technology?
The dynamic payback period is 4.20 years and the net present value is 340.48 k$. Compressed air energy storage technology is recognized as a promising method to consume renewable energy on a large scale and establish the safe and stable operation of the power grid.
What is compressed air energy storage (CAES)?
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
How do compressed air energy storage systems work?
In compressed air energy storage systems, electricity runs a compressor on land to produce compressed air. During this process, waste heat is captured and can be used to increase the round-trip efficiency from about 60 percent to as high as 80 percent. The compressed air is then pressurized to match the pressure at the ocean floor where the balloons are located.
Are compressed air energy storage systems a natural fit for wind farms?
CAES appears to be a natural fit with the wind farms presently under construction. This is because CAES can operate on a brief enough time scale to balance out variations in the power grid that are triggered by wind fluctuations. The future market potential for compressed air energy storage (CAES) systems is substantial.
