A techno-economic assessment of CO2 capture in biomass and waste-fired combined heat and power plants – A Swedish case study

The need to reduce global CO2 emissions is urgent and might be facilitated by carbon capture storage (CCS) technologies. Sweden has a goal reach net-zero 2045. Negative bio-CCS (BECCS) have been proposed as important strategies this target at the lowest cost. Swedish district heating sector constitutes large potential for BECCS, with biogenic point sources of in form combined heat power (CHP) plants that burn biomass residues from forest industry. This study analyzes 110 existing or waste-fired CHP plants. Process models steam cycles give impacts absorption-based CCS on electricity production, while system unit commitment model gives impact plant operation capture. results provide cost transport nearest harbor truck: up 19.3 MtCO2/year could captured range 45–125 €/tCO2, corresponding around 40% total fossil fuel-based emissions. would sufficient meet 3–10 Mt/year BECCS
