  3. Pipeline Issues • Effect of impurities on physical properties of CO2 and equations of state impacts pipeline design – pipeline hydraulics, avoidance of hydrate formation & two phase flow etc • Transient conditions (e.g. blow down , start up & shutdown) need special consideration for avoidance of two-phase conditions • HSE/ Regulatory/Design codes issues needs to be defined as it is important in pipeline routing. • Risk of long running brittle fractures (due to cooling effects around leaks) and long running ductile fractures (due to phase changes during depressurisation). Network design, development, operation and management (metering & custody transfer etc) • Strategy for development of infrastructure – how much CO2 to collect, when. Top 16 sources account for around 40% of CO2 output

  4. Offshore Pipelines: Additional Issues • No experience of transporting CO2 for long distances offshore. The only subsea CO2 pipeline that has been laid is the Snohvit pipeline • Pressures typically 50 to 150 bar for existing offshore pipelines. Maintaining sufficiently high pressures for delivery specifications could be a problem • Availability of existing infrastructure- Trunk lines etc • Upgrading existing infrastructure for EOR • Integration of onshore and offshore networks • Decommissioning Vs. Re-use • Pipeline integrity and fitness for purpose in re-use • Hydrostatic pressure may be mitigating factor with regard to brittle fracture • Impurities introduce variables in most aspects of CO2 transport.

  7. Summary of Progress Update at Newcastle. • Technical & Regulatory requirement (Completed): • Fundamental knowledge of hydraulics have been established. • Model validation with real-time pipeline data. • Regulations and design codes. • Input data into scenario models which include source and sinks – Transport scenario building (ongoing) • Identification of sources and sinks - large sources will be chosen. Awaiting input for sinks. • Material issues –Fracture propagation models • Network dev. and mgmt • Existing Infrastructure – availability in the North Sea

  8. On-going/future work • Transient modelling with OLGA and STONER – Start up , shut down, cyclic source operation, line pack etc. • Validation of Models with Real time pipeline data from Kinder Morgan. • Developing fracture propagation models for CO2 pipelines. • GIS routing exercise based on pipeline design codes

  9. Networking Activities • Contacts with Industry : AMEC, BP, Polytec Norway, Advantica, KMCO2: -Stoner transient software loaned to the University for CO2 on an academic license with sponsored training -OLGA multiphase transient training sponsored by Polytec and the software is used on Polytec premises -Kinder Morgan and Denburry CO2 company has agreed to provide data for model building and validation.

  14. Theme A6 – UK Infrastucture & Regulation OBJECTIVES • Identifying, locating and classifying the sources comprehensively. • Identifying and locating suitable offshore sites for EOR and/or storage. • Developing/ designing/ modelling transport systems to bridge the two.

  15. Supporting slides - Impurities

  16. Supporting Slides - Large scale infrastructure • The total CO2 emissions from all reporting UK industrial sites was 283Mt in 2004 • Most of the major sources are power plants, steel plants and petrochemical complexes • The 20 largest power plants represent 49% of the total industrial emissions. • It has been estimated that there is sufficient CO2 storage capacity in the UKCS oil and gas fields to store all current UK industrial emissions for between 13 and 38 years.
