“…This is because when considering the substantial lengths of CO 2 pipelines, a miscalculation in the optimum diameter can result in incurring an additional capital cost that could have been avoided. In this regard, several sources indicated that consideration of technical factors, such as material roughness, flow rate, pressure drop per unit length, viscosity/density of the fluid and differences in topography, are necessary for determination of the appropriate diameter [84,[139][140][141].…”

Transport of carbon dioxide (CO 2 ) via pipeline from the point of capture to a geologically suitable location for either sequestration or enhanced hydrocarbon recovery is a vital aspect of the carbon capture and storage (CCS) chain. This means of CO 2 transport has a number of advantages over other means of CO 2 transport, such as truck, rail, and ship. Pipelines ensure continuous transport of CO 2 from the capture point to the storage site, which is essential to transport the amount of CO 2 captured from the source facilities, such as fossil fuel power plants, operating in a continuous manner. Furthermore, using pipelines is regarded as more economical than other means of CO 2 transportThe greatest challenges of CO 2 transport via pipelines are related to integrity, flow assurance, capital and operating costs, and health, safety and environmental factors. Deployment of CCS pipeline projects is based either on point-to-point transport, in which case a specific source matches a specific storage point, or through the development of pipeline networks with a backbone CO 2 pipeline. In the latter case, the CO 2 streams, which are characterised by a varying impurity level and handled by the individual operators, are linked to the backbone CO 2 pipeline for further compression and transport. This may pose some additional challenges.This review involves a systematic evaluation of various challenges that delay the deployment of CO 2 pipeline transport and is based on an extensive survey of the literature. It is aimed at confidence-building in the technology and improving economics in the long run. Moreover, the knowledge gaps were identified, including lack of analyses on a holistic assessment of component impurities, corrosion consideration at the conceptual stage, the effect of elevation on CO 2 dense phase characteristics, permissible water levels in liquefied CO 2 , and commercial risks associated with project abandonment or cancellation resulting from high project capital and operating costs.2

“…For a fixed total flow rate (Qt), the optimum diameter, Dt should be the same irrespective of the initial flow rate but Equation (7) gives increasing values of Dt with increasing Q1. Equation (8) Wang et al [56] presented Equation (5) to calculate the trade-off point between the use of a trunk pipeline and single point-to-point separate pipelines that transport CO 2 from two sources starting production at different times. The trade-off point does not depend on the length of the pipeline if the pipeline length is less than or equal to 150 km (Equation (5a)).…”

CO2 Pipeline Design: A Review

There is a need to accurately design pipelines to meet the expected increase in the construction of carbon dioxide (CO 2 ) pipelines after the signing of the Paris Climate Agreement. CO 2 pipelines are usually designed with the assumption of a pure CO 2 fluid, even though it usually contains impurities, which affect the critical pressure, critical temperature, phase behaviour, and pressure and temperature changes in the pipeline. The design of CO 2 pipelines and the calculation of process parameters and fluid properties is not quite accurate with the assumption of pure CO 2 fluids. This paper reviews the design of rich CO 2 pipelines including pipeline route selection, length and right of way, fluid flow rates and velocities, need for single point-to-point or trunk pipelines, pipeline operating pressures and temperatures, pipeline wall thickness, fluid stream composition, fluid phases, and pipeline diameter and pressure drop calculations. The performance of a hypothetical pipeline was simulated using gPROMS (ver. 4.2.0) and Aspen HYSYS (ver.10.1) and the results of both software were compared to validate equations. Pressure loss due to fluid acceleration was ignored in the development of the diameter/pressure drop equations. Work is ongoing to incorporate fluid acceleration effect and the effects of impurities to improve the current models.

“…The typical pipeline length used ranges from 150 to 750 km, which covers most of the possible cases for CCS pipeline construction [5]. For example, in North America a large percentage of CO 2 sources and potential sinks are within 150 km [3].…”

This paper shows the effects of storage capacity on the selection of least cost CO 2 transport infrastructure design where there are two candidate injection sites (sinks) and a static supply of CO 2 (source). We investigate the least cost pipeline configuration under different combinations of CO 2 flow rates, pipeline lengths and storage capacities. A frequency distribution of least cost design shows that the capacity of the smaller sink is one of the main drivers for pipeline design. The insights gained from this study can also be applied in large-scale CO 2 pipeline networks optimisation.
