Abstract:
Technical innovation is indispensable for driving the low-carbon transition of the cement industry. Bioenergy with carbon capture and storage (BECCS) emerges as a critical technology to facilitate carbon neutrality. Quantifying the technical potential and economic costs of BECCS application in the cement industry is of significant importance. Based on the china biomass-emission-sink matching model (C-BESMM), the potential application of BECCS in the cement industry by 2060 was assessed. The results show that to achieve net-zero emissions in existing cement facilities, the biomass consumption could reach 29 million tons/year and the volume of CO
2 storage could reach 535 million tons/year by
2060, with cement plants integrating biomass blending and carbon capture generating approximately 42 million tons/year of negative emissions. Biomass consumption plays a crucial role in emission reduction before 2040, while carbon capture becomes the primary driver after 2040, with energy efficiency improvements contributing steadily throughout the period. Regions with high biomass consumption include Guangdong, Shandong, Yunnan, and Henan. Hebei, Henan, Liaoning, and Guangxi lead in CO
2 capture. 98% of the unit emission reduction costs are between −100−800 yuan/ton of CO
2. Among them, about 4% can achieve negative costs. Provinces with relatively large amounts of negative-cost emission reductions include Hebei, Shandong. Improving the biomass blending ratio, enhancing the biomass utilization rate as energy, and expanding the types of available biomass are conducive to increasing the biomass utilization volume in the cement industry, which is more beneficial for cement plants in reducing residual emissions and achieving “net zero”.
