Corporate image, European Emission Trading System and Environmental Regulations, encourage pulp industry to reduce carbon dioxide (CO 2) emissions. Kraft pulp mills produce CO 2 mainly in combustion processes. The largest sources are the recovery boiler, the biomass boiler, and the lime kiln. Due to utilizing mostly biomass-based fuels, the CO 2 is largely biogenic. Capture and storage of CO 2 (CCS) could offer pulp and paper industry the possibility to act as site for negative CO 2 emissions. In addition, captured biogenic CO 2 can be used as a raw material for bioproducts. Possibilities for CO 2 utilization include tall oil manufacturing, lignin extraction, and production of precipitated calcium carbonate (PCC), depending on local conditions and mill-specific details. In this study, total biomass-based CO 2 capture and storage potential (BECCS) and potential to implement capture and utilization of biomass-based CO 2 (BECCU) in kraft pulp mills were estimated by analyzing the impacts of the processes on the operation of two modern reference mills, a Nordic softwood kraft pulp mill with integrated paper production and a Southern eucalyptus kraft pulp mill. CO 2 capture is energy-intensive, and thus the effects on the energy balances of the mills were estimated. When papermaking is integrated in the mill operations, energy adequacy can be a limiting factor for carbon capture implementation. Global carbon capture potential was estimated based on pulp production data. Kraft pulp mills have notable CO 2 capture potential, while the on-site utilization potential using currently available technologies is lower. The future of these processes depends on technology development, desire to reuse CO 2 , and prospective changes in legislation. Keywords Bioenergy with carbon capture and storage BECCS.

“…In standard CaL systems, approximately 45-50% of the thermal input into the entire system (power plant and CaL) is introduced in the oxy-fired CFB calciner. 37 As can be seen in Fig. 3, the thermal input to the calciner can be drastically reduced by integrating the energy storage system.…”

“…Post-combustion CO 2 capture by CaL has developed rapidly in the last five years up to the scale of the MW th with several pilot plants [29][30][31][32][33][34][35] due to the similarity between its reactors and those of existing circulating fluidized bed power plants and the lower energy penalty compared to that of other CCS systems since extra power can be obtained from the additional heat input required to drive the sorbent regeneration reaction. 36,37 The use of CaO/CaCO 3 in CaL systems makes it possible to integrate a thermochemical energy storage system by taking advantage of the reversible reaction of CaO with CO 2 at high temperature. There is already background knowledge about the use of CaO/CaCO 3 to store nuclear 38,39 or solar energy [40][41][42] or to increase the flexibility of the integrated gasification combined cycle plants.…”

“…Different methods for supplying the energy needed for CaCO 3 calcination in the calciner reactor have been studied in the literature over the years, but none of them have been yet developed or proven on a sufficient scale for application. 4 However, the one having reached the largest development consists of operating the calciner under oxyfuel conditions, burning within the calciner additional fuel with pure O 2 as an oxidant. 5 CaO + CO 2 ↔ CaCO 3 ΔH 298 K = −178.8 kJ mol…”
