Abstract Reduction of CO 2 emissions is regarded as necessary to limit the consequences of increased CO 2 in the atmosphere. Carbon capture and storage will play an integral part in future reduction of CO 2 emissions together with energy optimization. Development of an efficient CCS infrastructure is the key to reaching proposed emission goal. In the current project the focus is on CO 2 emissions in the Skagerrak-Kattegat region. The project encompasses all aspects of CCS, but in this article the focus is on CO 2 transport infrastructure. Different infrastructure scenarios are proposed and costs are compared. This will be an iterative process and a final recommendation will be given by the end of the project period. Preliminary results will be provided in this article and are limited by the specified assumptions. Currently two scenarios, storage in the Skagerrak-Kattegat region and one outside, are estimated and compared. Both scenarios assumed that all the CO 2 emitted in the region is available simultaneously and that no ramp-up is necessary. Storage in relatively close proximity to the emission sources is preferable in an economic perspective and the initial estimations indicate this.
