This document discusses various modes of transporting carbon dioxide (CO2), including pipelines, trucks, ships, and railways. It notes that CO2 can be transported long distances via pipelines in a dense supercritical phase. For rail transport, CO2 must be liquefied and refrigerated to transport larger quantities in pressurized rail cars. Ship transport involves loading liquefied CO2 at offshore floating terminals to allow access for large tankers and create distance from populated areas. Each mode of transport has advantages and disadvantages regarding safety, capacity, and infrastructure requirements.
