System description The integration of the coal-fired power plant (CFPP) with the liquid CO 2 energy storage (LCES) system has here been suggested for the enhancement of the operational flexibility of the CFPP and the efficiency of the LCES system.
The report offers a comprehensive breakdown of the capturing site for different emitting sources, such as a newly constructed coal power plant, a retrofitted coal power plant, or a steelworks plant. The estimated capturing costs for those plants range from about US$30 to US$60/t-CO2.
Zhou et al. proposed a coupled system of compressed steam energy storage and Rankine cycle in a thermal power plant, which reduced coal consumption by 63.42 g/ (kW⋅h) and improved exergy efficiency by 2.99 % during deep peak regulation.
Furthermore, LCOD is determined to be 151.29 USD/MWh. Nevertheless, the manuscript has some limitations. The manuscript provides the combination of a 600 MW coal-fired power plant with molten salt energy storage, and discusses its coupling method and provides possible ways of peaking.
Energy, exergy and economic analyses are deeply evaluated. The peak range of CFPP is from 18.39 % THA to 106.35 % THA. In order to improve the peaking performance of the coal-fired power plant (CFPP), this paper proposes a scheme, which integrates a CFPP with the high-temperature and low-temperature molten salt thermal storage.
But we can see that the efficiency of the method ae) is significantly higher than that of other ways, which makes other ways almost unacceptable. Therefore, we only determine the coupling position of coal-fired power plants and molten salt energy storage based on efficiency.
