A Comparative of Life Cycle Assessment of Post-combustion, Pre-combustion and Oxy-fuel CO2 Capture

Abstract This paper presents a life cycle assessment (LCA) of three different carbon dioxide (CO 2 ) capture technologies, namely post- combustion, pre-combustion and oxy-fuel capture. The Boundary Dam Power Station (BDPS) in Saskatchewan, Canada was chosen as a case study for modeling of operations at the electrical generating station. This study showed that CO 2 capture technologies have the potential of reducing greenhouse gas (GHG) emissions. Where an increase in the impact categories associated with soil and water was observed, the release of pollutants to the atmosphere were reduced and became more manageable in their waste streams.
