Abstract

Abstract:

The low-carbon transformation of coal-fired units is one of the effective means to reduce carbon emissions in the short and medium term. In particular，energy storage technology can further enhance the application potential of carbon capture systems by providing auxiliary regulation.This paper systematically summarizes the current state of application of carbon capture units and energy storage technology，with a focus on the characteristics of carbon capture technology and the application features of various energy storage technologies. Research finds that energy storage technologies such as thermal storage， electricity storage， and flywheel energy storage are applicable to coupling with coal-fired units equipped with carbon capture system. The benefits mainly manifest in performance enhancement， economic operation， and pollutant control. Meanwhile， the paper further explores the application prospects of energy storage technology in carbon capture coal-fired units， emphasizing that parameter matching is a key factor in the successful coupling of these systems. On this basis， it is necessary to carry out coordinated optimization of energy storage charging and discharging strategies to fully tap the system's regulatory potential. The development of this technology is expected to focus on the coupling of multiple storage systems as well as on meeting the demands for peak-shaving and frequency regulation in carbon capture coal-fired units， thereby providing valuable insights for the low-carbon transformation of existing coal-fired units.

Key words: energy storage technology, coal-fired units, carbon capture, coupling technique
