The purpose of this data-file is to model the economics of liquefying CO2 for transportation in a ship, rail car or truck, in order to facilitate the rise of CCS, especially at smaller scales.
Our baseline is a cost of $15/ton, using c100kWh of energy per ton of CO2, which is approximately equivalent to a c3% energy penalty on the combustion process that generated the original CO2. There is scope for optimization, including from demand shifting.
Our calculations are based on a literature review of technical papers, and aggregating data into the energy costs of CO2 liquefaction, across different pressures and temperatures.
