This report reviews carbon dioxide (CO2) capture technologies, including those that might come online in the 2020s. It describes the types of technology being developed and how efficiency will increase with development. It also describes the potential for synergies between CO2 capture systems and heavy emitting industry.
Two different systems (post-combustion carbonate looping and chemical-looping combustion) are currently being tested at small scales but could be working at 10 MW within 10 years, although there are uncertainties about the costs of this development. This report ranks post combustion capture as being ahead in terms of development. Cost-efficiency estimates of different systems are not dissimilar given the margins of uncertainty and suggest that the costs of electricity generation with CCS will increase in the range of 30–80 %. Cost-efficiency data is limited for looping systems, however preliminary analyses suggest that these advanced technologies maybe competitive compared to amine-scrubbing (MEA) technology. It is important to note that caution must be applied when comparing cost-efficiency estimates in the literature and that significant uncertainty is introduced when comparing technologies at different stages of development and deployment.
