Project: Boundary Dam
Company/Alliance: SaskPower, Fluor, Hitachi, Babcock & Wilcox Canada, Neill and Gunter Ltd, Air Liquide and SNC Lavalin-Cansolv
Location: Boundary Dam Power Station, Estevan, Saskatchewan, Canada
Size: 110 MW ( 1Mt/yr)
Capture Technology: Post-combustion amine
CO2 Fate: EOR via 100 km pipeline
Current Status: Construction of retrofit unit
Start Date: 2014
The total cost of the project is estimated to be $1.355 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.
-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.
- Boundary Dam is still on tra
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.
SaskPower is also involved with Aquistore, a research project managed by the Petroleum Technology Research Centre (PTRC). The Aquistore project will take captured and compressed CO2 and transport it by pipeline to a site where it will be injected in a deep saline formation 2,200 metres (or 2.2 kilometers) below the surface. The capture site will be announced soon. The project aims to collect data which can be applied to the CO2 storage process at the Boundary Dam Project and other CCS projects.
