What I was referring to, and I'm not too sure about the question, is that carbon capture is best done at a plant that is a large, single-source emitter, like a coal-fired plant. Now, there are plans to do carbon capture at upgraders. One of the pilot projects will be done, they hope, at the Shell Scotford Upgrader near Edmonton. It's called the Quest project. They're hoping to capture the CO2 from a plant that actually produces hydrogen. They need hydrogen to help upgrade the bitumen. So there is some limited potential for carbon capture when it comes to the upgraders.
When it comes to the actual extraction process on the ground in the Athabaska oil sands, it seems very doubtful at this point that they can use carbon capture, because, for example, in the mining of the oil sands, most emissions there come from things like the giant trucks they use to haul the tar sands. Also, when it comes to in situ development, it means burning a lot of natural gas, and the natural gas effluent stream is very expensive to capture the CO2. So it seems that the extraction process does not lend itself well to carbon capture.
