IntroductionIntroduction• What is IEA GHG and what we do• Discuss recent work IEA GHG has undertaken
on summarising learning from existing large scale projects
www.ieagreen.org.uk
IEA Greenhouse Gas R&D ProgrammeIEA Greenhouse Gas R&D Programme• A collaborative research programme founded in 1991• Aim: Provide members with informed information on the
role that technology can play in reducing greenhouse gas emissions.
• Produce information that is:Objective, trustworthy, independentPolicy relevant but NOT policy prescriptiveScientifically reviewed by external Expert ReviewersSubject to review of policy implications by Members
• Funding approx £2.5 million/year

What have we learnt studyWhat have we learnt study• Internal IEA GHG study activity started in 2009• ‘Large scale’ CCS projects identified according to agreed
criteria • Questionnaires sent to operators• Results analysed for key learning points for capture,
transport and storage elements• Report completed• Starting second phase of in-depth analysis of key issues• Activity to be repeated in 2 year cycles• Results feeding into GCCSI acttivies

Criteria for largeCriteria for large--scale operational projectsscale operational projects
• Indicative criteria defined for ‘large-scale operational projects’• Was, or had been, operational by the end of 2008, and either:-
• Captured over 10,000 tCO2 per year from a flue gas• Injected over 10,000 tCO2 per year with the purpose of geological
storage with monitoring• Captured over 100,000 tCO2 per year from any source• Coal-bed storage of over 10,000 tCO2 per year
• Commercial CO2-EOR was excluded unless there was a monitoring programme to provide learning
• Did not need to be fully integrated• Added term ‘large-scale operational’ to IEA GHG Projects Database

Extent of CoverageExtent of Coverage• If integrated CCS from electricity
production is a 4 link chain:• Electricity production• Capture• Transport• Storage
• 2 and 3 link chains have been demonstrated over 1Mt CO2 per year

Extent of coverage Extent of coverage -- CaptureCapture• 13 plants capturing from combustion processes
• 11 post-combustion• 1 pre-combustion• 1 oxyfuel
• 9 projects source CO2 from industrial processing (Natural gas separation, ammonia, LNG, hydrogen production)
• Multiple fuels represented• Hard coal• Lignite• Natural Gas• Industrial processes
• Over 10Mt of CO2 captured per year

CaptureCapture
• Amine scrubbing demonstrated at 1Mt/year scale on natural gas plants• No significant operational problems reported
• No demonstrations on power plants yet• Not in a position to decide which is best capture
options• All three options still on the table• Allowed impurity levels will define costs
www.ieagreen.org.uk
Technical ChallengesTechnical Challenges• Post combustion capture on flue gas
• Large number of pilot plants in operation• A lot of commercial activity• Technology not yet demonstrated at scale
• Pre combustion capture• Technology components available but whole process
integration could be a challenge• Hydrogen turbine not commercially available?
• Oxy fuel combustion• Pilot scale tests needed to build confidence in this option.

SummarySummary• CO2 has been injected into:
• Unconsolidated sand bodies offshore (Sleipner)• Both tight sandstone and carbonate reservoirs
on shore (In-Salah & Weyburn)• Depths ranging from 800 to >3000m
• Some injection problems identified• No insurmountable problems
• Injection wells• Single well - Sleipner• Multiple distributed wells - Weyburn

Extent of coverage Extent of coverage –– MonitoringMonitoring• 2D seismic• 3D seismic• 4D seismic• Vertical seismic profiling• Cross-well seismic• Electrical conductivity• Microseismic• Passive seismic• Soil gas sampling• Detector arrays• Eddy covariance
• Observation wells• Time lapse microgravity• Well temperature and
pressure• Well logs• Tracers• Ground water geochemistry• Interferometry• Satellite imaging• Tilt meters
www.ieagreen.org.uk
Monitoring ExperienceMonitoring Experience• No firm evidence from any of the large scale
projects that leakage is occurring• Weyburn (~7years), Sleipner (~13 years), Rangeley
(~25 years)• Only one project has identified any surface seepage –
Rangeley• Most recent results indicate CO2 at surface is
biologically converted from CH4 microseepage• Monitoring lifetimes are short <25 years• Cannot quantify injection volumes or seepage
rates at present

environmental impacts of leakage along faults
