Technically, CO2 can be transported through pipelines in the form of a gas, a supercritical fluid or in the
subcooled liquid state. Operationally, most CO2 pipelines used for enhanced oil recovery transport CO2 as
a supercritical fluid. In this paper, supercritical fluid and subcooled liquid transport are examined and compared,
including their impacts on energy efficiency and cost. Using a commercially available process simulator,
ASPEN PLUS 10.1, the results show that subcooled liquid transport maximizes the energy
efficiency and minimizes the cost of CO2 transport over long distances under both isothermal and adiabatic
conditions. Pipeline transport of subcooled liquid CO2 can be ideally used in areas of cold climate or by
burying and insulating the pipeline. In very warm climates, periodic refrigeration to cool the CO2 below
its critical point of 31.1 C, may prove economical.
