Energy consumption of air energy storage power generation

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.

How much CO2 does a compressed air energy storage system emit?

Besides, the proposed system’s CO 2 emission is 258 kg/GWh. This study provides a new option for enhancing the performance of compressed air energy storage through the system integration.

Why is energy storage technology important?

Energy storage technology plays an important role in ensuring the reliable supply of electricity and promoting renewable energy consumption. On the power generation side, the application of energy storage technology can reduce the standby capacity configuration and improve the economy of renewable energy power generation.

What is biomass energy storage and energy release process?

In the energy storage process, the feedwater from the biomass power generation system is used to cool the compressed air in the compressed air energy storage system. In the energy release process, the flue gas from the biomass power generation system is used to heat the compressed air.

How does energy storage work?

Due to the existence of the energy storage system, the power generation of the thermal power generation system is reduced, and the amount of coal is reduced, so that the pollutants generated by coal burning (NOx and soot, etc.) are successively reduced (Roushenas et al., 2021).
