Existing examples include the Midwest Carbon Express in the United States, an offshore CO 2 pipeline connecting Belgium with Norway, and the Delta Corridor connecting parts of Germany and the Netherlands. The key obstacles to pipeline buildout are permitting timelines, capital costs, and public/political support. CO 2 shipping offers safe, reliable, and flexible CO 2 transportation well-suited to short distances and low to medium volume (around 2,000 t or less 144 ), especially in cases where pipeline transport is not an option. Shipping may be more suitable near-term for DACCS where low volumes of CO 2 are produced, excluding the integration of DACCS into industrial clusters and DAC Hub projects.
