| Summary: | In Europe, most of the CO2 that needs to be captured is expected to be stored offshore due to the lack of social acceptability for onshore CO2 storage. This means that in the coming decades, infrastructure to transport several hundred million tonnes of CO2 from coastal locations to offshore storage sites will be required. In practice, multiple transport strategies and technological options could be used, and a key question of CCS stakeholders is how to best do so and what the associated costs would be. The present study addresses this question for Northern Europe using a geographical visualisation approach. Base case evaluations, which consider commercial technologies, show the predominance of shipping to floating receiving facilities as a cost-efficient way for transport to offshore sites. However, transport via an onshore receiving facility and pipeline-based transport are used for storage locations near shore and near the port, respectively. The precise boundaries between optimal transport strategies depend on the annual volume of CO2 being transported. If low-pressure shipping (i.e. at 7 barg) becomes available, the ship-based approach will be further advantaged. Similarly, once shipping with direct injection becomes commercially available, it would become cost-competitive for transport volume up to a couple of million tonnes per year and lead to similar costs as conventional shipping above. The development of low-pressure shipping and direct injection could be key to cost-efficiently reach storage locations in the Scottish and Norwegian part of the North Sea. |
