Air power generation and air energy storage

Can compressed air energy storage detach power generation from consumption?

To address the challenge, one of the options is to detach the power generation from consumption via energy storage. 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.

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.

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 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 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.

Can compressed air energy storage improve the profitability of existing power plants?
