Lack of Existing CO 2 Transport Infrastructure. To enable permanent storage, CO 2 can be either transported via pipelines or shipped to storage sites (either geological / in-situ mineralization storage sites or to plants for integration into durable products), which creates the need for reliable and low cost transport. In the first case, pipelines and compression stations along the pipelines are needed. Availability of multi-user CO 2 pipeline networks is key for reducing the cost of CO 2 transport and for the rapid deployment of DACCS.
