“…Nevertheless, a number of studies (Benson et al, 2003;Brunsvold et al, 2011;Chen et al, 2009Chen et al, , 2010Kazmierczak et al, 2009;Middleton and Bielicki, 2009;Morbee et al, 2011) examine how to obtain the optimal CCS transport network by minimising the present value (PV) of the total capital and operating cost of transport. This approach does not consider any extra CO 2 emissions related to operating the transport network and, therefore, does not necessarily yield the lowest CCS network cost per tonne of CO 2 avoided.…”
