This paper seeks to shed light on the costs of carbon capture by reviewing and comparing the available material on costs of capture for both mature technology and early plants, attempting to account for differences where possible. It mainly refers to US costs, for which the greatest amount of published analysis is available.

This paper seeks to shed light on the costs of carbon capture by reviewing and comparing the available material on costs of capture for both mature technology and early plants, attempting to account for differences where possible. This paper mainly refers to US costs, for which the greatest amount of published analysis is available. It focuses mainly on the capture part of the CCS process (including compression of the CO2). Capture and compression accounts for a large proportion of total CCS costs. Furthermore, transport and storage costs vary enormously with volume and distance of transport and type of sink.
