Pipelines are considered the most cost-effective and safest option to transport large amounts of CO2 over long distances. The aim of this study was to evaluate effect of the heat transfer on the pressure and temperature profiles of CO2 within pipeline networks in Australia. A one-dimensional, steady state, non-isothermal model for fluid networks was adapted for modelling CO2 flow. The model comprises of coupled fluid-dynamic (flow equation) and thermo-dynamic (energy equation) routines that are solved iteratively to account for the effect of temperature on mass transport parameters of CO2. The analysis considers pure CO2 described in two possible phases being liquid and supercritical. The pipeline outlet pressure and temperature were calculated for an Australian point-to-point network connecting main single sources to single storage sites. The outlet temperature was found to reach the soil temperature for onshore pipes and sea water temperature for offshore pipes in almost all cases apart from those which are very short (less than 100 km). The outlet pressure was shown to be dependent on the ambient and inlet temperature, flow-rate, length and diameter of each pipeline. The pressure drop increased as the inlet temperature increased due to higher level of turbulence during the transport.
