An integrated whole-system model of a CO2 capture, transport and storage (CCTS) network was developed in order to design the optimum network linking CO2 sources (e.g., power stations) with potential sinks (e.g., depleted oil reservoirs). This work is multiscale in nature, employing models describing system behaviour and interactions through a range of length and timescales. We used our model to determine the optimum location and operating conditions of each CO2 capture process while giving full consideration to the whole-system behaviour. Further, researchers assume a cost associated with a pre-specified 90% degree of capture. However, an important result of designing and analysing cost optimal CCTS networks for the UAE was that the cost optimal degree of capture is a site specific factor that depends on the flue gas characteristics, proximity to transportation networks and adequate geological storage capacity. The results of this study indicated an optimum capture rate lower than the one obtained by looking into account the economies of the capture plant alone. This conclusion serves to underscore the importance of a whole-system analysis of potential CCTS networks.
