There's been a lot of talk about what energy sources are used in the tar sands. We've talked about the fact that there is coke, which comes out as a byproduct of the system. That byproduct is relatively stable and can be stored. It doesn't go off into the atmosphere very quickly. I'm sure some does diffuse, but very little. It's relatively stable, but it's also an important energy source.
What we're saying is that there are gasification technologies that would allow you to start with that coke and water and produce hydrogen, carbon monoxide, and some carbon dioxide. The hydrogen and carbon monoxide you can use again as fuels. The hydrogen is particularly useful. You get some heat out of that process, but what you need is the ability to filter the carbon dioxide out of this hot gas stream coming out of the gasification process, and then collect it, transmit it, compress it, and put it underground in a safe, well-regulated, monitored way.
To be able to do that sort of thing, we need regulatory frameworks. We need to set up experimental programs in which we test diffusion of the underground reservoirs in the western Canadian basin. We have hardly started that. As David said, at one point we had a lead because we were actually starting to do some of it, but others have taken over, and we've sat passively.
I don't know whether that answers your question.
