Investment costs and CO2 reduction potential of carbon capture from industrial plants - A Swedish case study

In this work, the investment required to apply CO2 capture to large-scale industrial sources is assessed and discussed in a case study of Sweden - a highly industrialized region with relative proximity to large and well-documented storage sites in the Norwegian North Sea. The Swedish process industry is characterized by a large share of biogenic emissions, and therefore has a considerable Bio-Energy with Carbon Capture and Storage (BECCS) potential. The capital cost for CO2 capture is estimated for a standard MEA-based CO2 absorption process. The CO2 absorption process is applied to several industries - pulp and paper, oil and gas, steel, cement and chemical production - and dimensioned using process modeling. The equipment cost is subsequently estimated using a detailed individual factor estimation method. The capture costs are compared to estimates of the cost for transport and storage.
