5.4 CO2 transport
The reduction in the length of the pipeline for the reference case has reduced the overall transport costs and the contribution of transport cost to the overall cost of CCS. The cost to transport CO2 is estimated to be between US$1–2 per tonne of CO2, a decrease from US$3–4 per tonne of CO2 in 2009. This is due to the reduction of the pipeline length in the reference case from 250km in 2009 to 100km.
An opportunity to reduce the costs of CO2 transport is in increasing the CO2 flow through the pipeline, by combining the captured CO2 from multiple sources through a larger pipeline to a common storage site. The implementation of a common user pipeline can result in a cost of less than US$1 per tonne for CO2 transport.
