1 CCS Activities in Canada February 23, 2009 IZEC Workshop 2009 Toranomon Pastral Hotel, Tokyo Malcolm Wilson

2 Background Outline CCS activities capture CCS activities storage Recent results International Test Centre New project development the Saskatchewan Montana Project

3 Sources and Reservoirs

4 Options for CO 2 Capture

5 Trans Canada Pipelines Polygeneration facility near Regina 300 MW power production GE Gasifier Cost - $4+ billion Heat to Potash producer, H 2 to fertilizer plant Petroleum coke fuel source Up to 15,000 t/d CO 2 Plant on hold FEED study was to be conducted in 2009

6 TransAlta Evaluating the use of the Chilled Ammonia process in Alberta Is applying for some of the Alberta $2 billion in support for commercial scale projects Alberta funds to attain 5 million tonnes CO 2 per year storage

7 SaskPower Worked on oxy-fuel This demonstrated the need to go to pilot stage first Cost and parasitic load were too high to move ahead Currently working on Boundary Dam 3 Repowering of old 139 MW unit CO2 post combustion to be added, two 1500 tonne units On-stream 2014 approximately CO 2 to be sold for EOR

8 CONVENTIONAL COAL POWER PLANT CARBON AS CO2 (GAS) (CO2 released to atmoshpere is considered a climate altering greenhouse gas) ELECTRICITY CARBON AS COAL SHALLOW COAL BEARING FORMATIONS IMPERMEABLE FORMATIONS SaskPower's CLEAN COAL POWER PLANT DEEP OIL/GAS BEARING GEOLOGICAL FORMATIONS ELECTRICITY CARBON AS COAL SHALLOW COAL BEARING FORMATIONS IMPERMEABLE FORMATIONS CARBON AS CO2 (LIQUID) DEEP OIL/GAS BEARING GEOLOGICAL FORMATIONS

10 Alberta s s Integrated CO 2 Network (ICO 2 N) ICO2N consists of 18 leading companies from a variety of industries power, oil & gas, fertilizer, chemicals, metal refining ICO2N represents: More than 100 Mtpa of industrial emissions (14% of Canada s total emissions) Over 60% of Alberta s power generation ~ 95% of oil sands petroleum production Mandate is to work with provincial and federal governments to develop the CCS solution ICO2N has conducted several engineering, economic and other analyses:

12 Shell Canada s s Quest Project Shell is considering a Project to Capture and Sequester more than one million tonnes of CO 2 per year from its Scotford Upgrader, located near Edmonton. Oil sands mining region PEACE RIVER EDMONTON CALGARY CO2 Capture Scotford Upgrader Pipeline Sequestration near Scotford

13 Alberta Saline Aquifer Project (ASAP) Canadian pipeline co. Enbridge Inc. leading a group of 19 energy industry participants in the Alberta Saline Aquifer Project (ASAP). ASAP is a broad-based, industry-supported initiative that participants will roll out in phases: Phase 1 = identification of suitable locations for the long term sequestration (storage) of carbon dioxide in deep saline aquifers. It is expected to be completed by the end of Phase 2 = a pilot project during which sequestration sites will be designed to receive injected carbon dioxide. Later phases will involve expanding the project to a large-scale, long-term commercial sequestration operation.

14 WASP Consortium led by the University of Calgary Goal is to develop the concept of very large scale (gigatonne) storage Working on site evaluation

15

16 IEA GHG Weyburn Project This globally important project continues operation The project is now into a second phase The phase 1 report was issued in September 2004 and featured prominently in the IPCC Special Report on Carbon Capture and Storage Current phase focuses on improved risk evaluation, well integrity. Goal is again a $20 million (cash) project

19 Aquistore Capture of 500 tonnes per day from the reformer at a refinery/upgrader complex in Regina Storage in deep saline aquifer in the region (limited transportation) PTRC led project

20 International Test Centre Consortium operates for one more year 1 tonne per day unit Operates on natural gas boiler (11% CO 2 ) 4 tonne per day unit Operates on lignite fired unit (13% CO 2 ) Both units recently upgraded to high efficiency configuration Larger pilot recently operating in 35 C weather

24 Saskatchewan Montana Project Goal is to create a technology neutral full chain CCS facility 1000 tonne per day (approx) capture unit Pipeline into Montana (possibly Poplar Dome) Approximately 1 million tonne storage test Possibly combined with EOR (proximal to a number of sites with EOR potential)

25 Saskatchewan-Montana

26 Capture Unit Modular construction to cut construction costs Attached to 300 MW Lignite fired unit Will be designed to test any amine system Initial tests will mimic a load following coal plant (this will be transmitted right through the system) Full testing capacity with two pilot plants as well Independently operated
