“…Importantly, it has been 29 claimed that there is little experience to date on the actual behaviour of anthropogenic CO 2 in the supercritical phase and this poses a number of challenges for the integrity, reliability, safety and cost-efficiency of the pipeline [123,170,173,189,224]. It is a common understanding within the industry that the CO 2 transport pipeline network should be designed and developed within the remits of that of the oil and gas industry [32].…”

“…Furthermore, the current literature has emphasised the importance of reliable means of corrosion prediction that are necessary for the prevention of leakage, accidental discharge and loss of CO 2 resulting from corrosion [84,129,188,222,[225][226][227]. Finally, for effective control of CO 2 pipeline integrity, a management regime is required and this incorporates, among a number of other aspects, selection of material, inspection and monitoring, maintenance, operation, corrosion mitigation, evaluation of risks together with the concept of communicating these risks [114,129,[167][168][169][193][194][195][196]220,223,224,[228][229][230][231][232].…”

“…However, other studies have estimated this release rate at 8.5-15 ts -1 . Importantly, these figures depend on the pipe diameter, puncture size and the level of impurities that may affect the CO 2 stream phase, operating temperature and pressure, as well as on whether the CO 2 release and dispersion is planned or accidental [78,102,190,224,[234][235][236]. Furthermore, a change in the CO 2 phase gives rise to dry ice formation in the pipeline surroundings that has an indirect effect on the concentration and impurities around the faulty pipeline [190,237].…”

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

“…Considerable interest in modeling gas flow over topography has arisen from recent developments in CO 2 transport as a supercritical fluid through long-range pipelines for carbon sequestration (Duncan and Wang 2014). The possibility of a breach in a pipeline and associated gas flow has prompted investment in gas hazard assessment.…”

Volcanic gases are insidious and often overlooked hazards. The effects of volcanic gases on life may be direct, such as asphyxiation, respiratory diseases and skin burns; or indirect, e.g. regional famine caused by the cooling that results from the presence of sulfate aerosols injected into the stratosphere during explosive eruptions. Although accounting for fewer fatalities overall than some other forms of volcanic hazards, history has shown that volcanic gases are implicated frequently in small-scale fatal events in diverse volcanic and geothermal regions. In order to mitigate risks due to volcanic gases, we must identify the challenges. The first relates to the difficulty of monitoring and hazard communication: gas concentrations may be elevated over large areas and may change rapidly with time. Developing alert and early warning systems that will be communicated in a timely fashion to the population is logistically difficult. The second challenge focuses on education and understanding risk. An effective response to warnings requires an educated population and a balanced weighing of conflicting cultural beliefs or economic interests with risk. In the case of gas hazards, this may also mean having the correct personal protection equipment, knowing where to go in case of evacuation and being aware of increased risk under certain sets of meteorological conditions. In this chapter we review several classes of gas hazard, the risks associated with them, potential risk mitigation strategies and ways of communicating risk. We discuss carbon dioxide flows and accumulations, including lake overturn events which have accounted for the greatest M. Edmonds

An experimental investigation on pressure response and phase transition of supercritical carbon dioxide releases from a small‐scale pipeline

The prediction of the pressure response and phase transition in the event of an accidental carbon dioxide (CO 2 ) release from a ruptured pipeline is of significant importance for understanding the depressurization behaviour and hence the fracture behaviour. This article presented a small-scale experimental investigation on the pressure response and phase transition of supercritical CO 2 release from a pressurized pipeline with a relief orifice. High-frequency transducers and thermocouples were used to measure the evolution of CO 2 pressures and temperatures at different locations after release. The results indicated that pressures at different locations decreased nearly synchronously after release. No vapour bubble and pressure rebound generated in larger scale release experiments were found in our small-scale release experiments. The depressurization rate was greatly affected by the phase transition. During the release process, the supercritical CO 2 firstly turned into an unstable gas with a very great depressurization rate, then changed into the gas-liquid phase with a lower depressurization rate, and finally changed into gaseous CO 2 . The larger the relief diameter was, the longer the gas-liquid phase state lasted.
