Abstract
The objective of this study is to describe the complete transport chain of CO 2 between capture and storage including a ship transport. This last one is composed by the following steps: Shore terminal including the liquefaction, temporary storage and CO 2 loading. Ship with a capacity of 30,000 m 3. On or off shore terminal including an unloading system, temporary storage and export towards the final storage. Between all the possible thermodynamic states, the liquid one is most relevant two options are compared in the study (−50 °C, 7 bar) and (−30 °C, 15 bar). The ship has an autonomy of 6 days, is able to cover 1000 km with a cargo of 2.5 Mt/year. Several scenarios are studied varying the geographical position of the CO 2 source, the number of harbours and the way the CO 2 is finally stored. Depending on the option, the transport cost varies from 24 to 32 €/tCO 2. This study confirms the conclusion of a previous study supported by ADEME, the cost transport is not negligible regarding the capture one when ships are considered. Transport by ship becomes a more economical option compared with an off shore pipeline when the distance exceeds 350 km and with an onshore pipeline when it exceeds 1100 km.
