Abstract: Carbon capture and utilization (CCU) is a pathway to deep decarbonization. However, limited understanding of the CCU sector's technical and economic performance has hindered investment and deployment. Thus, this study comprehensively reviews CCU technologies by analyzing their strengths and applicability and quantifying their technical and economic performance based on data harmonization techniques. Results show that physical absorption presents favorable carbon dioxide (CO2) capture cost (12.38 USD/t CO2 on average) and CO2 capture energy consumption (1.03 GJ/t CO2 on average). Pipelines are the most economical method for CO2 transportation, with a mean cost of 0.025 USD/tkm. For CO2 chemical utilizations, dimethyl ether synthesis has the shortest economic payback time (1.88 years on average) and methanol synthesis has the highest energy efficiency (51.7% on average). Overall, CO2-enhanced oil recovery is well-rounded in terms of technological maturity and economic cost-effectiveness, with an average payback time of 4.1 years. For China, the annual CO2 mitigation potential of CCU peaks in 2050 (reaching 1691 Mt of CO2), which is mainly derived from the power, cement, and chemical production sectors. Key opportunities for CCU development in China include deploying chemical absorption in the cement and power sectors, reducing physical absorption costs in the chemical production sector, developing highly active and stable catalysts to improve the conversion rate of CO2 to dimethyl ether, and supporting CO2-enhanced oil recovery via economic incentives.
