Carbon capture and storage is considered one of the most promising technological options for the mitigation of CO2 emissions from the power generation sector and other carbon-intensive industries that can bridge the transition period between the current fossil fuel-based economy and the renewable and sustainable technology era. CCS involves the capture of CO2 from the sources, the transport CO2 through dedicated pipelines and ships, and the storage of CO2 in geological reservoirs, such as depleted oil and gas fields and saline aquifers, for its permanent isolation from the atmosphere. The development of CCS technologies has increased significantly in the last decades; however, there are still major gaps in knowledge of the cost of capture, transport and storage processes. Pipelines have been identified as the primary means of transporting CO2 from point-of-capture to site where it will be stored permanently but there is little published work on the economics of CO2 pipeline transport and most cost studies either exclude transport costs or assume a given cost per tonne of CO2 in addition to capture costs. The aim of this report is to identify the elements that comprise a CO2 pipeline network, provide an overview of equipment selection and design specific to the processes undertaken for the CO2 transport and to identify the costs of designing and constructing a CO2 transmission pipeline infrastructure.
