摘要：CO2-based carbon-neutral organics production processes could potentially reshape the chemical industry. However, their feasibility and net carbon footprint rely strongly on the sources of H2. Herein, we present a comprehensive comparative techno-economic analysis of CO2-based methanol (CO2TM) and aolefins (CO2TO) manufacturing using various feedstock supply modes: (1) the standalone mode with external CO2 but H2 from on-site water electrolysis, (2) the integrated mode with both CO2 and H2 recovered from coal-chemical plants, and (3) the integrated mode with recycled CO2 but H2 from on-site water electrolysis. The integration of CO2TM and CO2TO into coal-to-olefins (CTO) and coal-to-methanol (CTM) facilities is currently cost-effective and can reduce net CO2 emissions by 65.7% and 68.5%, resulting in a three-fold and two-fold increase in carbon efficiency, respectively. As carbon tax policies and electrolysis technologies continue to evolve, standalone CO2TM and CO2TO are projected to become more economically competitive than CTO and CTM by 2035-2045.
