Calculating the consequences of a CO2-pipeline rupture

Focusing on the costs and consequences of large-scale CO 2 transport in steel pipes, transport in liquid form is superior to gaseous form. A modelling study was performed on the basis of a 350 MWel coal-fired power plant, with CO 2 removal amounting to 70 kg CO 2 per sec for disposal. An aquifer disposal site at an injection pressure of 200 bar and a transport distance of 30 km is the study baseline. Both economic evaluations and a risk assessment of a pipe rupture showed that liquid transport of CO 2 from the power plant to the injection site was optimal at a pressure of 60 bar.
