CO2's transport technologies via under pressure pipelines, from the points of production to those of storage, are quite reliable and tested, and are similar to those used for natural gas transportation, also as regards pressure levels (around 80 bar).
In the pipelines, the transport can take place both in the liquid state and the gaseous state, or by ship (or land ) in liquid or solid form.

In the United States were acquired significant experiences on the CO2 transport  via pipelines (1600 km) for applications in oil field with techniques EOR (Enhanced Oil Recovery) with the use of systems both low and high pressure.

The transport in tankers is currently not commercially experienced, although Japan and Norway have already studied projects for the realization of tankers for CO2 transport in the liquid state.
