The preferred location for storage facilities varies depending on which region of the world is considered – in Northern Europe, onshore storage is being ruled out by governments and public attitudes, so storage under the sea (which is a feasible option for much of Northern Europe) is preferred. In North America it seems more likely that storage onshore will be used, not least because of experience with other onshore injections but also because, in most cases, the distances involved would make it too expensive to transport CO 2 to offshore locations. Similarly in China the rapidly growing interest in CCS focuses on use of CO 2 (for EOR) onshore. In Australia, although some of the largest potential stores are offshore, onshore locations have also been seriously considered.
