CO2 transportation may take place between a capture plant and a sequestration site. This paper presents the state of the art of the existing experience including CO2 thermodynamics, corrosion and hydrate aspects, role of impurities, and security and safety. Two case studies of a coal steam plant producing 350 t/h are compared, one using the classical dense phase process and the other using a liquid refrigerated one, with the costs induced for a 100 km transport. Some ideas are given for what could be a future French network. Finally an overview of transportation by ship is given, where the CO2 thermodynamic properties will probably imply pressurized and refrigerated capacities.
