Combining the results from Figure into the levelised cost of compression, LCOCC, as shown in Figure , leads to other interesting features. As seen from the figure, the minimum levelised cost is not achieved when the CAPEX is lowest nor when power is lowest. It occurs at a liquefaction/pumping pressure of 87 bar. When the power (and hence the variable OPEX) is at its lowest values between 40 bar and the critical pressure, the CAPEX is at its highest values, and when the CAPEX is the lowest (15 bar liquefaction/pumping) the power (variable OPEX) is at its highest. For the selected case, apparently the 87 bar liquefaction/pumping pressure is an optimal compromise between CAPEX and OPEX. It is interesting to note that one of the major compressor OEM's promote a hybrid solution of combined compression/pumping of CO 2 to final delivery, by compression up to 80-83 bar, followed by pumping to the final required pressure .
