Integrating carbon dioxide (CO₂) capture in biomass or waste-fired combined heat and power (CHP) plants has been considered a key measure to achieve negative emissions. This paper proposed a bottom-up approach based on a dynamic modelling to evaluate the potental of nationwide negative emissions. As heat supply is often prioritized by CHP plants, unchanged heat generation is a prerequisite of this study. Two operating modes (OMs) for the integration of CO₂ capture are investigated, which can represent the upper and lower boundaries of CO₂ capture: OM1 aims to maximize the amount of captured CO₂, while electricity generation can be sacrificed; OM2 aims to maximize the amount of captured CO₂, while the electricity generation is maintained unchanged. Sweden is employed as a case study.
