Once the CO2 has been captured at the emission source and processed so as to have suitable output parameters as regards its composition, pressure and temperature, the stage of transportation to storage begins.
Following the separation of flue gases, the CO2 extracted is compressed until it reaches a condition similar to a liquid state.
It is then transported in pipes (similar to the pipelines used by the natural gas industry) or in road tankers or ships if the CO2 source is distant from the storage site.
A widespread deployment of CCS technology will require a pipeline network. Currently there are some 5000 km of pipelines in the world transporting CO2.
Given the innovative nature of this type of transportation, various areas are currently being worked on, most notably:
