Co2 transportation system

The results of the performed screening study indicates that it is possible to transport CO2 over large distances within a reasonable unit cost. It is evident that the effect of large scale solutions to reduce unit costs are substantial. The transportation unit cost for a fully utilized large diameter pipeline over 1500 kilometers is estimated at approximately 6$ per tonne, while transportation through a 16 inch pipeline, corresponding to CO2 from a single 1000 MW gas fired power station, over the same distance, is approximately 42$ per tonne. The transportation cost should be compared with carbon tax of 50$ per tonne CO2 in force in Norway and the proposed EC energy / carbon tax of 10 $ per barrel of oil, which is equivalent to approximately 24 $ per tonne CO2. Large diameter pipelines require large investments and multilateral agreement. Therefore, the possibilities to establish an integrated large scale CO2 transportation system across country borders and continents is a possibility, but the perspective is long term. Although an integrated large scale CO2 transportation system is not likely to appear in our decade or even in the next two or three, it may turn out to be the chosen solution for the mid 21th Century if we are entering a greenhouse driven future.
