10 Transport costs
To illustrate the impact of different variables like location, capacity and type of transport a high level cost estimation model was developed. The basis for the cost estimate is the LLSC as presented Figure 59. The transport by pipeline is assumed to be in the dense phase for all scenarios. The previously presented schematic was based on subcritical onshore pipeline transport. In this evaluation longer distances are reviewed for which subcritical transport is not recommended.

The different building blocks consist of different chain components. For these chain component a transportation tariff, expressed in an indexed cost per tonne of CO2 transported, was defined based on component cost estimates and budget quotes. The limited time and available information at this stage of development for the concept required extrapolation of available data to provide a range of data suitable for different capacities and distances. It was assumed that only ship/barge costs and pipeline costs were influenced by both capacity and distance. Other component costs are only related to the capacity. The obtained costs include capital investment costs as well as operational costs. Indexed cost figures are used to analyze trends and development properties of the concept.
