“…Among the various CO2 pipeline cost models [18], the Parker model [23,26] was adopted in this study excluding the material cost because its results were most similar to the costs of natural gas pipelines in Korea. The applicability of the Parker model to CO2 pipeline transport was verified in a recent study [27]. The material cost can be directly calculated by multiplying the pipeline weight by the price per ton.…”

Abstract:In this study, a techno-economic model was used to calculate the costs of CO2 transport and specify the major equipment required for transport in order to demonstrate and implement CO2 sequestration in the offshore sediments of South Korea. First, three different carbon capture and storage demonstration scenarios were set up involving the use of three CO2 capture plants and one offshore storage site. Each transport scenario considered both the pipeline transport and ship transport options. The temperature and pressure conditions of CO2 in each transport stage were determined from engineering and economic viewpoints, and the corresponding specifications and equipment costs were calculated. The transport costs for a 1 MtCO2/year transport rate were estimated to be US$33/tCO2 and US$28/tCO2 for a pipeline transport of ~530 km and ship transport of ~724 km, respectively. Through the economies of scale effect, the pipeline and ship transport costs for a transport rate of 3 MtCO2/year were reduced to approximately US$21/tCO2 and US$23/tCO2, respectively. A CO2 hub terminal did not significantly reduce the cost because of the short distance from the hub to the storage site and the small number of captured sources. OPEN ACCESSEnergies 2015, 8 2177

“…The annual fixed operating cost is set at 6% of total direct costs for the CO2 conditioning and booster stations (Chauvel et al, 2003), while the annual pipeline fixed operating costs are assumed to represent 1.5% of the investment cost (Knoope et al, 2014). The variable operating costs are a function of the amount of CO2 transported, and cover consumption of utilities: electricity and cooling water.…”

This study analyses the effect of transporting 13.1 MTPA CO 2 with impurities over a distance of 500 km on the operating and investment costs. In the cases study, two different impurity levels coming as a result of gas sweetening (GAS) and from capture from oxy-fuel combustion (OXY). The analysis includes the cost for the conditioning and the compression of the CO 2 stream after capture, from atmospheric conditions to transport conditions in the dense phase. In the calculation of the operating cost in terms of compression power and cooling requirements, the effect of the impurities are taken into account by using real thermo-physical properties depending of local fluid temperature and pressure and including heat transfer with the surroundings. The analysis investigates the total cost of choosing different pipeline diameters for transporting CO 2. The technical analysis shows that the number of required booster stations increases from 2 to 17 going from a 28" to an 18" pipeline and from 3 to 25 in the worst case with (GAS). In the second technical comparison, the feed flow rate for the CO 2 mixtures has been reduced so that the installed compression power for transport will be equal for all three cases. In this analysis a 24" pipeline with 4 booster stations was used. The techno-economic assessments show a significant impact of the impurity cases considered on the CO 2 conditioning and transport design and cost. Indeed, in the Oxy-feed and Gas-feed cases, the specific conditioning and transport costs are respectively 13 and 22% higher than in the Base-feed case for the cost-optimal diameter. In absolute value, this represents a direct increase of the specific conditioning and transport cost of 2.3 and 3.8 €/t CO2,avoided . Even if the cost evaluation leads to the same cost optimal diameter for the three impurity cases considered, it is important to note that this result is specific to the transport system considered in this paper and that in principle different impurity cases can lead to different cost-optimal diameters especially for low pipeline diameters. The impact of impurities on an existing pipeline infrastructure design not taking into account these potential impurities show an even stronger cost impact. Indeed, the cost evaluations shows that the specific cost of the Oxy-feed and Gas-feed cases can be expected to be respectively at least around 20 and 40% more expensive than in the Base-feed case due to the lower amounts of CO 2 transported and the important cost-penalty associated with the CO 2 emissions not transported. Finally, while the cost presented here considered only the impact of impurities on the conditioning and transport cost, impurities can also be expected to have a significant impact on the technical and economic performances of the whole CCS chain. This therefore highlights the importance of evaluating, on a case-to-case basis, the tradeoffs between impact of impurities on the CCS cost and cost of impurities removal in order to provide recommendations on cost-optimal level of imp...

Carbon dioxide Capture and Storage/Sequestration (CCS) technology has attracted attention as an ideal method for most carbon dioxide reduction needs. When the collected carbon dioxide is transported to storage via pipelines, the direct transport is made if the storage is close, otherwise it can also be transported via an intermediate storage hub. Determining the number and the location of the intermediate storage hubs is an important problem. A decision-making algorithm using a mathematical model for solving the problem requires considerably more variables and constraints to describe the multi-objective decision, but the computational complexity of the problem increases and it also does not guarantee the optimality. This research proposes an algorithm to determine the location and the number of the intermediate storage hub and develop a simulator for the connection network of the carbon dioxide emission site. The simulator also provides the course of transportation of the carbon dioxide. As a case study, this model is applied to Korea.
