Boundary Dam CCS Project
The Boundary Dam Integrated Carbon Capture and Storage Project is SaskPower’s flagship CCS initiative. Through the development of the world’s first and largest commercial-scale CCS project of its kind, SaskPower is making a viable technical, environmental and economic case for the continued use of coal.
The $1.35 billion Boundary Dam Project will see the integration of a rebuilt coal-fired generation unit with carbon capture technology, resulting in low-emission power generation. in 2014, this will become the World's First Post-Combustion Coal-Fired CCS project.
This project will transform the aging Unit #3 at Boundary Dam Power Station near Estevan, Saskatchewan into a reliable, long-term producer of 110 megawatts (MW) of base-load electricity and reduce greenhouse gas emissions by one million tonnes of carbon dioxide (CO2) each year. That’s equivalent to taking more than 250,000 cars off Saskatchewan roads annually.
The captured CO2 will be transported by pipeline to nearby oil fields in southern Saskatchewan where it will be used for enhanced oil recovery. CO2 not used for enhanced oil recovery will be stored in the Aquistore project.
In addition to CO2, there will be opportunities for the sale of other byproducts from the Project. Sulphur dioxide (SO2) will be captured, converted to sulphuric acid and sold for industrial use. Fly ash, a byproduct of coal combustion, will also be sold for use in ready-mix concrete, pre-cast structures and concrete products.
- Demonstrate the economic, technical and environmental feasibility for coal-fired power generation with CCS.
- Reduce greenhouse gas emissions by approximately one million tonnes per year.
- Support the development of industry-wide CCS regulations and policies.
Why carbon capture and storage on coal?
Natural gas prices rise and fall unpredictably, while coal is abundant and affordable in Saskatchewan. Government regulations and the need to reduce greenhouse gas emissions around the world means we need to find a way to keep producing affordable power, but in a way that reduces our impact on the environment.
As SaskPower works on renovating and growing our aging power infrastructure, coal remains the most affordable power source for customers and CCS will make that coal sustainable for our environment.
With the Boundary Dam project and research done at our second venture into CCS, the Shand Carbon Capture Test Facility, Saskatchewan will add to worldwide research also being conducted elsewhere in Canada, the United States, Europe, Australia, China and Japan. The Boundary Dam CCS Project will make Canada a global leader in carbon capture and storage.
