What is CCS?What is CCS?
Carbon Capture & Storage (yes, sequestration too!)Includes four (4) elements…capture, transport, storage and
risk assessment too!• Capture Technologies; varied• Transport; relatively well understood• Storage; means dealing with uncertainty• Risk Assessment; means gaining acceptance
Carbon Capture & StorageCarbon Capture & Storage

Three Options;Post CombustionPre CombustionOxy fuel
Two Options;PipelinesShips
Three Options;Coal seams, 40 Gt CO2
Oil and gas fields, 1,000 Gt CO2
Deep saline aquifers – up to 10,000 Gt CO2

Global CO2 Storage Potential;Estimates vary wildly and are the subject of intense debate. No-one has gone prospecting for pore space, so no-one really knows!
IPCC Special Report on CCS (www.ipcc.ch) :
Pessimistic minimum: 200 GtCO2 (55 GtC)
Pretty likely: 2000 GtCO2 (550MtC)(= total CO2 emissions to date)
Possible: 10,000GtCO2 (2700 GtC) (in unexplored saline aquifers)
Current coal burned worldwide ~ 9 GtCO2 (2.5GtC)(http://cdiac.esd.ornl.gov/trends/emis/glo.htm)
REGION OF INFLUENCE
• Areal extent 10 km beyond CO2 flood limits
• Geological architecture of system
• Properties of system– lithology– hydrogeological
characteristics– faults
• Can be tailored for different RA methods and scenario analyses

Saskatchewan-Montana Project Current Partners
SKSK--MT Partnership GoalsMT Partnership Goals• Construct a technology-neutral CO2 capture plant
(reference plant) at an existing coal-fired power generating station in Saskatchewan that has the flexibility to test a range of post-combustion carbon capture technologies;
• Construct a North American CO2 storage facility in northeastern Montana with injection infrastructure that allows for CO2 enhanced oil recovery;
• Develop confidence in various technologies through open and transparent information flow; and
• Develop a North American training facility that meets the needs of a growing CCS industry and regulators. We are building a “new natural gas industry”.
Capture Unit• Capture target: 500 - 1,000 tonnes/day• “Technology neutral”• Operated as an independent entity• Include 4 tonnes/day and 1 tonne/day pilot units
Overall system• Designed to be a major training and capacity
building unit – Practical training on capture unit– Field training on storage site
Project Region
The underground pipeline attached to the capture unit at an existing SaskPower plant will deliver CO2 from Saskatchewan to a geological storage site in northeastern Montana on the northwestern flank of the Williston Basin.
Coronach, SK
Wolfpoint, MT
Estevan, SK
Two possible SaskPower coal-fired plants are being considered as sites for the capture/reference plant in southern Saskatchewan: Coronach or Estevan lignite-fired units.
Project Components• Capture unit: Test and demonstrate process design
and operations, particularly impacts of capture units on power plant operations.
• Pipeline: Provide insight on pipeline routing and test varying CO2 input volumes to mimic a load-following power plant output.
• Storage: Encompass site screening, site permitting, drilling of storage wells, monitoring of CO2 injection and plume dispersion and ultimately site closure. Target 1,000,000 tons stored.
• Risk Assessment: Conducted by IPAC-CO2 (an independent entity) to undertake objective and transparent analysis of data and risks associated with geological storage.

AddressAddress……Objections to CCSObjections to CCS
• High Costs of Capture• Regulatory Uncertainty• Societal Acceptance• Energy Penalty or Parasitic Load hit, etc.• System Performance Issues et al• Other Excuses!
Project MilestonesMarch – August 2009: Design of reference plant, land-owner discussion on pipeline routes, development of permitting action plan
June 2009: Risk assessment begins by IPAC CO2 and MSU
July – September 2009: Reference plant construction begins
October – December 2009: Power plant site work begins
Summer 2010: Site characterization, site preparation at SaskPower plant, pipeline construction, and installation of capture unit finished
Summer 2010: Training program starts
Winter 2010-2011: Drilling of injection and observation wells
Winter 2010 -2011: Baseline monitoring process
Spring 2011: Injection of CO2 starts
What is IPAC-CO2?• It’s an independent,
internationally distributed network that provides and advances global expertise to benchmark, evaluate and advise on the risks and performance of geological storage of carbon dioxide.
IPAC-CO2 GoalsCapacity Building: • Develop expertise in a number of
CCS areas through research and practical demonstration projects
• Ensure experience is captured and communicated
Technology Development• Improve storage subsurface
assessment models• Simplify models for industry and
government use• Populate models with the best
data and results from leading CCS projects and programs around the world
Information and Services• Develop standards/guidelines• Assess methodology for CCS
project risk and advise on appropriate risk comparison
• Answer technical and other questions in a balanced and objective manner to enable CCS projects to proceed
• Engage with and educate various stakeholders and public on CCS to increase acceptance
• Network internationally to ensure learnings from researchers and projects are built upon and/or utilized
IPAC Framework
IPAC-CO2 & IndustryIPAC-CO2 will:
• Inform industry on standards and policy
• Initiate research to fill knowledge gaps
• Peer review project RA/PAs• Exchange knowledge• Train/advise national
regulators and developers• Mediate in conflict• Act as expert witness• Design accreditation process
and criteria• Provide policy relevant outputs
IPAC-CO2 will not:
• Make policy recommendations• Do any proprietary work (I.e.
commercial RA operations)• Provide routine consultancy• Represent a company• Engage in any work that could
lead to a conflict of interest
IPAC-CO2 Deliverables• Fundamental & Applied Research • New Technology Development• New Techniques & Best Practices• Dissemination of Results & Findings • Training & Capacity Building for Industry and
Government• Communication with respect to CCS• Verification (credits, screening studies, MMV programs)• Terminology maintenance (IEA GHG Report)
IPAC-CO2 Funding• In place: Royal Dutch Shell
Government of SaskatchewanAlston & Bird (in-kind)University of Regina (in-kind)University of Alberta (in-kind)
• In discussion: Government of Canada
• Others: Clinton FoundationIndustryOther Governments
IPAC-CO2 Regional Centres• Geographically distributed
- Canada (Universities of Regina, Alberta, Calgary, Dalhousie)- United States (now developing US partners)- Europe (Imperial – confirmed)- Australia (CO2 CRC - confirmed)- Brazil (CEPAC – to be confirmed shortly)- South Africa (SANERI - confirmed)- China (North China Electric Power University - confirmed)- India (TERI - in progress)
