One challenge in CCS is related to the prevention of running-ductile fracture in CO 2 -carrying pipelines. Commonly used tools for ensuring crack arrest in pipelines hinge mainly on semi-empirical models, which may not be appropriate for CO 2 transport since they have been developed and fitted for natural gas and older pipeline materials, and due to an assumed decoupling of the fluid decompression and fracture propagation phenomena. In this paper, we apply a coupled fluid-structure model to a case with pure dense liquid CO 2 in a modern high-toughness steel pipeline, and compare the results one would obtain from directly applying the uncoupled models to the same case without any re-fitting to test data. For this case, the coupled model indicates that a significantly thicker pipeline wall may be required to prevent running-ductile fracture than what is predicted by the uncoupled models. Therefore, using the uncoupled models for such cases might not be conservative.

This paper presents an overview for repurposing and the potential blockers with respect to current code compliance based on Wood case studies of international code requirements and recent repurposing study work. Based on rudimental calculations, comparing both energy Natural Gas (NG) and H2 carriers, repurposed pipelines can be capable of achieving circa 80-90% of the energy flow rate if design pressure can be maintained, or 50-60% if the design pressure is de-rated. If other operational restrictions are considered, such as flow velocity it can potentially have additional knock-on effect on the achievable flowrate and consequently to energy ratio.  The feasibility of pipeline repurposing for hydrogen service is critical to the energy transition. Careful consideration of code requirements, and further research and development currently ongoing is required in order to remove over-conservatisms in design to maximise the achievable energy flow rate when repurposing to hydrogen service.
