Project: Boundary Dam
Company/Alliance: SaskPower, Fluor, Hitachi, Babcock & Wilcox Canada, Neill and Gunter Ltd, Air Liquide and SNC Lavalin-Cansolv
Location: Unit #3, Boundary Dam Power Station, Estevan, Saskatchewan, Canada
Size: 139 MW gross. 110 MW net ( 1Mt/yr) Retrofit
Capture Technology: Post-combustion amine
CO2 Fate: EOR in Weyburn field (90% of CO2). Transportation is via 66 km pipeline built by Cenovus. Excess CO2 is to be used at the Aquistore project 2 km away
Start Date: Started in October 2014
The total cost of the project is estimated to be $1.24 billion. The Boundary Dam project received $240 million from the federal government in 2011, of which about $180 million has already been spent. The provincial government is also supporting the project. Saskpower announced in October 2013 that the project was $115 million over budget.
Revenue from the sale of CO2 is expected to offset the project costs. Sulphur dioxide (SO2) will also be captured and sold.
The retrofit is located at Boundary Dam's Unit 3. The project will capture 95% or 1Mt/yr. This project has been re-sized from an earlier plant to build a 300 MW clean coal facility near Estevan which had been shelved by the previous provincial government because of its escalating cost ($1.5 billion to $3.8 billion). This smaller scale project has occurred after the federal government gave the province $240 million.
There are no other energy sources nearby so power generation from coal is the only option. There are a few nearby lignite mines, which reduces the cost of transportation to the plant. There is a SOX capture unit which will produce 93% purity capture rate for sale as sulphuric acid. In addition 35% of the fly ash will be sold for construction.
-March 2010: SNC Lavalin and Cansolv Technologies Limited were selected to oversee the engineering, procurement and construction activities for the Boundary Dam project. Cansolv, a wholly-owned subsidiary of Shell Global Solutions, will supply the carbon capture process design for the project. Cansolv has developed an innovative system of capturing sulphur dioxide at coal-fired power plants, which has been adopted by three facilities in China. Cenovus will also set up injection wells and build a 40 mile-long pipeline connecting the Weyburn EOR project with Boundary Dam.
- December, 2010: SaskPower announced that it was proceeding with the $354 million rebuild of 150 MW Unit 3 at Boundary Dam, the province's largest coal-fired generating station.
- January 2011: Babcock and Wilcox were contracted to rebuild the boiler in Unit 3.
- July 2011: SaskPower signed a $30 million contract with Stantec for engineering consultancy during the design and construction of the system.
- December 2012: SaskPower announced that Cenovus Energy of Calgary will purchase the full volume of 1Mt/yr of CO2 captured at Boundary Dam for EOR projects operated by Cenovus operated near Weyburn.
- January 2013: Alberici will remove the old Unit 3 boiler and install a new Hitachi 160 MW turbine.
- May 2013: The UK Carbon Capture and Storage Research Centre (UKCCSRC) and SaskPower signed a MoU for a 3 year research initiative aimed at improving costs and performance of CCS.
- October 2014: Boundary Dam starts
A $5.2 million, pre-commercial-scale chemical absorption technology demonstration pilot plant has already been operating at Boundary Dam as part of the International Test Centre for CO2 Capture. Part-funding of $1.2 million came from the Canada/Saskatchewan Western Economic Partnership Agreement.
Cenovus Energy built the 66-km pipeline to transport the CO2 to nearby oil fields in the southern part of the province, where it will be used for enhanced oil recovery. The unused CO2 will be stored by the independent Aquistore research project, 3.4 km deep in a brine and sandstone water formation. Aquistore is a research project managed by the Petroleum Technology Research Centre (PTRC).
