Carbon capture, storage and utilisation technologies: A critical analysis and comparison of their life cycle environmental impacts

• 27 life cycle assessment studies reviewed of which 11 focus on CCS and 16 on CCU. • CCS reduces the GWP by 63–82% but increases some other life cycle impacts. • The GWP of CCS is significantly lower than that of CCU. • However, other environmental impacts from CCS are higher compared to CCU. This paper presents a first comprehensive comparison of environmental impacts of carbon capture and storage (CCS) and carbon capture and utilisation (CCU) technologies. Life cycle assessment studies found in the literature have been reviewed for these purposes. In total, 27 studies have been found of which 11 focus on CCS and 16 on CCU. The CCS studies suggest that the global warming potential (GWP) from power plants can…
