In our own modelling work we've shown that it would be applied in the oil sands. We have technical challenges around the purity of CO2 streams; we don't think those challenges are insurmountable. And a tremendous amount of research and development is happening right now so that eventually CCS can be applied to the oil sands.
The Pembina Institute would support—and we have already, with Turning the Corner and its update in 2008—the CCS performance standard. Rather than a performance standard, our institute would support an outright regulation, seeing CCS as a mandated approach to new-build oil sands developments, or in fact new-build coal-fired electricity as well.
The bottom line is that we're not quite there yet to make it economic, but with a full-court press I think we can figure it out, and we should figure it out.
