Methodology to Calculate the CO2 Emission Reduction at the Coal-Fired Power Plant: CO2 Capture and Utilization Applying Technology of Mineral Carbonation

Abstract

This study introduces a novel methodology to calculate the carbon dioxide (CO2) emission reduction related to residual emissions, calculating the CO2 emission reduction through a 2 MW (40 tCO2/day) carbon capture and utilization (CCU) plant installed at a 500 MW coal-fired power plant in operation, to evaluate the accuracy, maintainability, and reliability of the quantified reduction. By applying the developed methodology to calculate the CO2 emission reduction, the established amount of CO2 reduction in the mineral carbonation was evaluated through recorded measurement and monitoring data of the 2 MW CCU plant at the operating coal-fired plant. To validate the reduction, the accuracy, reproducibility, consistency, and maintainability of the reduction should be secured, and based on these qualifications, it is necessary to evaluate the contribution rate of nationally determined contributions (NDCs) in each country. This fundamental study establishes the concept of CCU CO2 reduction and quantifies the reduction to obtain the validation of each country for the reduction. The established concept of the CCU in this study can also be applied to other CCU systems to calculate the reduction, thereby providing an opportunity for CCU technology to contribute to the NDCs in each country and invigorate the technology.

Advanced Ultra-Supercritical Coal-Fired Power Plant with Post-Combustion Carbon Capture: Analysis of Electricity Penalty and CO2 Emission Reduction

“…In the present analysis, the reheat pressure is limited at one-fifth of the main steam pressure in order to avoid exhaust steam qualities below 0.88. In the condenser, the exhaust steam is turned into liquid water 18 . The condensate pump (CP) sends water to the low pressure FWHs 19 .…”

“…Advanced ultra-supercritical power plants (A-USC) are expected to enter operation in the next decade for future large-scale CCS implementation. Lee et al [18,19] stressed the importance of developing reliable methodologies for quantifying CO 2 emission reduction through CCS at national basis. Nasirov et al [20] analyzed decarbonization possibilities in developing countries and concluded that wind and solar energy are future of electricity generation, but still 15% of the electricity will be from coal by 2050.…”

Fuelling power plants by natural gas: An analysis of energy efficiency, economical aspects and environmental footprint based on detailed process simulation of the whole carbon capture and storage system

“…In addition, also the few relevant scientific papers discussing economic aspects focus on coal-fired plants [39], and often consider a small nominal net power output related in most cases to pilot plants [40]. Moreover, the technical reports available in the literature usually do not consider the CCS option [41] or they do not include the transportation and storage of CO 2 .…”
