“…Actually, the techno-economic analysis of CFPP with CCUS retrofitting for China has been performed, noting that the capture cost ranges from 35 to 80 USD/t CO 2 . 13 , 38 , 41 However, most of them provided the preliminary knowledge of CCUS used in decarbonizing China’s power sector, ignoring the spatiotemporal variation of capture cost resulting from technology upgrades and regional differences. In this study, the plant-level capture cost is provided.…”

“…For CO 2 transport readiness, we use a transport distance of 500 km or less as criterion. 77 Transportation costs will increase with distance. A distance higher than 500 km will likely require the use of liquid CO 2 vessels which will be used in the Longship project in Norway.…”

About 26% of global CO2 emissions came from coal-fired power plants (CP) in 2021. Furthermore, 72% of this came from Asian countries, especially China and India. Therefore, reducing CO2 emission from CPs is a must if Asian countries were to achieve net-zero CO2 emission by 2050 or soon afterward. In this study, we evaluate the potential contribution of carbon capture and storage (CCS) to decarbonize CPs in selected Asian countries. Our study area consists of the east coast of China, India, Sumatra, West Java and Kalimantan of Indonesia, Malaysia, Brunei, Vietnam, and Thailand which contains one-quarter of the global CP capacity. We screen all existing CPs in the study area for CCS retrofit readiness, considering the size and age of CPs, the CO2 transportation distance, and the storage capacity of nearby oil and gas reservoirs and saline aquifers. Analyses show that out of 520 CPs in the study area, 305 (59%) pass the screening criteria for CCS-retrofitting. If fully implemented at a 90% CO2 capture rate, CCS retrofitting will result in the abatement of 1.55 Gtpa of CO2, equal to 65% of CO2 emission from CPs in the study area and 16% of global CO2 emission from CPs. Furthermore, retrofitting CPs with CCS has the potential to reduce CO2 emissions by 18% for Malaysia, 26% for India, and 26% for Vietnam. However, the biggest CO2 abatement will be realized in India (715 Mtpa) and China (636 Mtpa). These results quantify the potential contribution of CCS in decarbonizing CPs in Asia. Policy implications to accelerate CCS implementation based on our findings are also discussed.

“…The integrated energy system (IES) increases the proportion of renewable consumption, improves the efficiency of integrated energy use, and promotes energy's green and ecological development through the coordinated planning of multiple energy sources (Qiu et al, 2022;Shen et al, 2022). China proposes peaking its carbon emissions by 2030 and achieving carbon neutrality by 2060 (Liu et al, 2022), which requires a carbon capture system (CCS) (Paltsev et al, 2021) and carbon trading mechanisms (Yan et al, 2022;Shi et al, 2022) to achieve carbon emission reduction. Wind power (He et al, 2022), and photovoltaic (Yuan et al, 2022;Fu et al, 2022) permeability increases yearly.…”

To realize the integrated energy system (IES) low-carbon and economy dispatches and renewable energy utilization, the integrated energy system economic dispatch model introduces the liquid carbon dioxide energy storage (LCES) and carbon capture system (CCS). This paper proposes a low-carbon economic dispatch model for an integrated energy system that considers LCES and carbon capture system. The paper considers the impact of carbon trading mechanisms on systemic carbon emissions, aims to minimize the total operating cost of the system, and comparison of integrated energy system dispatch for two scenarios: integrated energy system equipped with LCES and integrated energy system equipped with battery energy storage. CPLEX simulation software simulates this comprehensive energy system. Analyzing the dispatching results from different perspectives, such as electric energy, thermal energy, and CO2 emissions. These results show that the proposed model effectively reduces carbon emissions, improves energy utilization, and achieves comprehensive low-carbon economic operation of the integrated energy system.
