Potential economies of scale in CO 2 transport through use of a trunk pipeline


Journal Article

A number of existing models for the transport of CO 2 in carbon capture and storage assume the CO 2 will be carried through isolated pipelines that connect each source to the nearest storage site. However storage costs will vary geographically, and it may be more economical to transport the CO 2 farther away to a lower cost storage site if the pipelines can be linked to the site via a primary trunkline. We evaluate this alternative by developing an engineering-economic model that computes the levelized cost of transporting captured CO 2 through pipes of different diameters and over varying distances. The model also computes the additional energy use and resulting CO 2 emissions involved in the transport and is used to arrive at a generalized correlation for estimating the cost of CO 2 transport ($/tonne/km) for different mass flow rates. Model results indicate that the cost for transporting CO 2 could be significantly reduced using a large-diameter trunkline networked to pipelines from individual CO 2 sources. This suggests that the design of CO 2 transport systems could be an important influence on the selection of storage sites, particularly where there is a tradeoff between nearby but high-cost sites and distant, low-cost sites. © 2010 Elsevier Ltd.
