• 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

Pipeline Issues

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.

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

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

Networking Activities

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.

Theme A6 – UK Infrastucture & Regulation

Supporting slides - Impurities

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.
