Materials optimisation for CO2 transportation in CO2 capture and storage

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).  This entails CO₂ transportation to selected sites for sequestration and storage. 

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 was developed enabling materials optimisation for CO₂ transmission in CCS.
