With the growing environmental constraints, global warming and public awareness, there is an
increasing incentive to reduce carbon emissions. One approach to achieving this is through CO2 capture and
storage (CCS). Once captured and compressed, CO2 must be transported to a long term storage site. In principle, transmission may be accomplished by pipelines, tankers, trains, trucks, compressed gas cylinders, as
CO2 hydrate, or as solid dry ice. However, only pipeline and tanker transmission are reasonable options for the
large quantities of CO2 associated with power stations, other industry activities or hydrocarbon production.
This paper combines current status of materials and corrosion options for CO2 transmission, outlining any
technology gaps that may exist. In addition, a simple guideline is presented enabling materials optimization for
CO2 transmission in CCS.
