3 Abstracts of Presentations: Carbon Capture & Storage Health and Safety: Challenges and Opportunities Rosemary Whitbread - Health & Safety Laboratory Sound health and safety credentials will be vital to the CCS sector in securing public, investor and wider industrial/commercial confidence crucial to the successful introduction and expansion of this essentially unfamiliar technology. The process of identifying, managing and controlling hazards should not be regarded as a barrier hampering deployment but rather a process specifically designed to prevent and eliminate problems that might otherwise retard the transition to a radically new UK energy system. The challenge comes in managing the uncertainty that surrounds understanding the hazards and demonstrating good risk management in the absence of established standards and guidance for CCS. CO2RISKMAN JIP: New Industry Guidance on Major Accident Hazard Management of the CCS CO2 Stream The presentation will introduce a new industry guidance developed through the CO2RISKMAN JIP to help CCS projects understand and manage their major accident hazard risks associated with handling very large quantities of impure CO2. The guidance covers the main links of the CCS chain (i.e. CO2 capture plant, on and offshore pipelines, buffer storage, ship carriers, offshore injection platforms and injection wells) and provides foundation information for someone entering the CCS industry through to specific guidance on CO2 stream hazard identification, hazard assessment and hazard risk treatment. COOLTRANS: Introduction and Overview Julian Barnett - National Grid This talk will set the scene and give an overview of the COOLTRANS Research Programme. COOLTRANS: Fracture Control and the Design of Dense Phase CO2 Pipelines Andrew Cosham - Atkins This talk will explain the work undertaken to consider the specification of the pipe toughness required to prevent the possibility of long running fractures arising. It will cover the methods that are used to define toughness requirements in dense phase CO2 pipelines and highlight the need for experimental validation. COOLTRANS: Routeing Dense Phase CO2 Pipelines Phil Cleaver - GL Noble Denton This talk will consider the application of risk assessment in establishing the requirements for routeing dense phase pipelines. It will cover the reasons why a new approach has been developed and will explain how this approach could be used in practice. CO2PIPETRANS JIP: Introduction and Overview This presentation will give an overview of the CO2PIPETRANS Joint Industry Project (JIP). Phase 1 of the JIP resulted in the development and release of DNV-RP-J202, a recommended practice for the design and operation of CO2 pipelines. Phase 2 is on-going with the aim of filling identified knowledge gaps through experimental research funded by the JIP partners. DNV-RP-J202 will then be updated to reflect the improved knowledge.

4 CO2PIPETRANS Work Package 1: CO2 Model Validation Data Collection and Public Sharing WP1 of the CO2PIPETRANS JIP has the goal of collecting and making available in the public domain suitable data that can be used for CO2 release model development and validation. The presentation will provide an overview of the work that has been undertaken at the Spadeadam test site to collect and share release and dispersion data from liquid and supercritical CO2 releases up to 150 bar and 150 C through orifices up to a diameter of 25 mm. The presentation will also present details of pipe depressurisation tests that are due to be completed in November and much larger dispersion releases that are being planned for early next year. Using the CO2PIPETRANS Data: Phast Validation for CO2 Releases Henk Witlox - DNV Software This presentation will present and discuss the validation of discharge and subsequent atmospheric dispersion for pressurised CO2 releases using the consequence modelling package Phast based on experimental data shared by the CO2PIPETRANS JIP. CO2PIPETRANS Work Package 2: CO2 Pipeline Fracture Arrest Experiments DNV, through WP2 of the CO2PIPETRANS JIP is managing test site work that is undertaking propagating crack experiments to collect crack propagation data for CO2 pipelines. This presentation will provide an overview of the propagating crack experiments undertaken in Norway and will also give details of the further large scale work planned for next year. CO2PIPETRANS Work Package 3: CO2 Corrosion Experiments The objective of WP3 of the CO2PIPETRANS JIP is to determine the corrosion mechanism and the corrosion rate of carbon steel in liquid and supercritical phase CO2 with various amounts of impurities like O2, H2, SOx, NOx, and H2S with water present at 50 and 500 ppmv. A large number of autoclave experiments have been performed with various combinations of impurities and the results will help determine a safe operating window for CCS projects. The presentation will provide an update on progress of this work. CO2PipeHaz: Materials and Safety Considerations for CO2 Pipeline Transportation Haroun Mahgerefteh - University College London Pipelines are considered as the most reliable and cost effective way of transporting large amounts of CO2 over long distances for Carbon Capture and Sequestration (CCS). Given that CO2 is an asphyxiant at high concentrations the safety of CO2 pipelines is central to the public acceptability of CCS as a viable means of combating the impact of global warming. Factors affecting the accurate hazard and risk assessment of CO2 pipelines include corrosion, hydrate formation and propensity to fast running ductile and brittle factures. Special consideration is given to the impact of impurities in the CO2 stream captured using various technologies on the above hazards. Some recent progress concerning the knowledge gaps in the modelling of outflow and subsequent dispersion of CO2 following the accidental rupture of pressurised CO2 pipelines will be presented.
