This poster on the UKCCSRC Call 2 project Shelter and Escape in the Event of a Release of CO2 from CCS Infrastructure (S-CAPE) was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-179. Pipelines are acknowledged as one of the most efficient and cost-effective methods for transporting large volumes of various fluids over long distances and therefore the majority of proposed schemes for Carbon Capture and Storage (CCS) involve high pressure pipelines transporting CO2. In order to manage the risk in the event of the failure of a carbon dioxide (CO2) pipeline, it is a core requirement that a separation distance between pipelines and habitable dwellings is defined to ensure a consistent level of risk. The aim of this project is to develop validated and computationally efficient shelter and escape models describing the consequences to the surrounding population of a CO2 release from CCS transportation infrastructure. The models will allow pipeline operators, regulators and standard setters to make informed and appropriate decisions regarding pipeline safety and emergency response. This poster presents some preliminary findings from the S-Cape project and: • Describes the development of analytical and Computational Fluid Dynamic (CFD) models to calculate the change in internal CO2 concentration within a building engulfed by a dispersing cloud of CO2. • Investigates the sensitivity of the CO2 concentration within a building to wind speed and the temperature of the CO2 in the pipeline. • Demonstrates how CFD models can be used to verify results obtained using computationally efficient analytical models.

This dataset provides the linepacking times that have been generated for a set of pipeline dimensions, flow rates, lengths and pressure conditions. This work has been funded by the UK Carbon Capture and Storage Research Centre within the framework of the FleCCSnet project (UKCCSRC-C1-40). The UKCCSRC is supported by the EPSRC as part of the Research Councils UK Energy Programme (https://doi.org/10.1016/j.ijggc.2017.06.002). This dataset forms the basis of the work and analysis presented in the paper: Aghajani, H, Race, JM, Wetenhall, B, Sanchez Fernandez, E, Lucquiaud, M & Chalmers, H 2017, 'On the potential for interim storage in dense phase CO2 pipelines' International Journal of Greenhouse Gas Control.
The project will three-dimensionally image hydraulically conductive features in the reservoir, caprock and overburden of an active CO2 injection site: the Aquistore site, Canada. Our research will provide important information on potential migration pathways within the storage complex to inform future monitoring strategies at the Aquistore site and at future storage sites. We will monitor micro-seismic events prior to, and during, CO2 injection using a three-component nanoseismic surface monitoring array which will complement data collected by the existing geophone network at the site. This analysis can be used to provide deep focussed monitoring information on permeability enhancement near the injection point. As injection continues it will also enable imaging of any flowing features within the caprock. Grant number: UKCCSRC-C1-19.

This project will produce and disseminate the first design and operating guidelines for the flexible operation of CCS pipeline networks. The research will explore how CCS pipeline networks can react effectively to short, medium and long term variations in the availability and flow of CO2 from capture plants, as well as responding to the constraints imposed on the system by the ability (or otherwise) of CO2 storage facilities to accept variable flow. The work will develop relevant scenarios for modelling the likely variability of CO2 flow in a CCS pipeline network, develop hydraulic models of CO2 behaviour, engage stakeholders in the process through practitioner workshops, and deliver guidelines to the industry and other interested stakeholders.
