In Norway, the full-scale project Longship will capture CO2 from one or two sources, transport the CO2 by ship to a hub at Kollsnes, where the CO2 is heated and pumped before transported by a pipeline to an offshore storage site. It is likely that other CO2 sources in Norway will adopt the same transport strategy, i.e., transport of captured CO2 from the capture site to the hub at Kollsnes before being transported in a common pipeline to permanent storage.
In this paper, the results of an investigation into CO2 ship transport configurations for CO2 sources located in the Nordland County in Norway is presented. Five regional hub locations have been identified, each serving one or more emission sources. These regional hubs are then connected to the Kollsnes hub via ship transport. Each regional hub will be different and are sized according to the CO2 volumes to be transported. There could be many suitable shipping configurations based on the ship size and number of ships used for the operations. Six shipping configurations have been described and cost estimated. The configuration where each regional hubs is served by a dedicated ship, is according to the results the most cost effective alternative. It has the lowest CAPEX and an OPEX in line with the other configurations. The ships are specifically sized according to the CO2 volume at each regional hub. This configuration is also attractive as it does not depend on the readiness of the other hubs as they are operated independently of each other.
