Argument: The transportation of captured carbon can be very expensive
After capture, the CO2 would have to be transported to suitable storage sites. This is done by pipeline, which is generally the cheapest form of transport. In 2008, there were approximately 5,800 km of CO2 pipelines in the United States, used to transport CO2 to oil production fields where the CO2 is injected in older fields to extract oil. COA conveyor belt system or ships could also be used. These methods are currently used for transporting CO2 for other applications. According to the Congressional Research Service, "There are important unanswered questions about pipeline network requirements, economic regulation, utility cost recovery, regulatory classification of CO2 itself, and pipeline safety."
