In the context of CDR, a pipeline is method for sending carbon dioxide a long distance from the point of CO2 removal to the point of sequestration. This approach is sometimes selected when the removal location lacks an appropriate means of sequestration, and the sequestration method lacks the infrastructure to support co-located removal. The need for a pipeline is more prevalent with carbon capture and storage (CCS) because the carbon emission source has likely been located without regard to carbon dioxide sequestration potential, whereas CDR projects are more likely to be developed with integrated removal and sequestration.

A typical pipeline operates at 1100 to 2200 psig and between 60° to 90°F, compressed to greater than the critical point. Captured CO2 contains impurities unlike conventional pure CO2 supplies, and this affects the physical properties of the fluid in ways that can significantly affect the pipeline capacity. - Design of CO2 Transmission Pipeline Systems
