With regard to the colours of hydrogen and the approach for the hydrogen that's being produced in Canada right now, it is, if we use the colour code, grey hydrogen. We're also producing blue hydrogen. We also have some of the largest electrolyzers in the world and plan to build more in Varennes that will produce green hydrogen.
Our objective, as part of this transformation or transition pathway, is to move towards the lowest carbon intensity of hydrogen, and that's how we move forward. The price points right now—and Dr. Hoskin can speak to this more—for the cleanest hydrogen, the green hydrogen and the blue hydrogen, are more expensive, but we know that over time, as more is produced and as technology advances, it is going to come down, and that's what really gets us to its being a viable transition strategy.
In the hydrogen strategy for Canada, our focus is on carbon intensity and reducing carbon intensity, and when we talk about hydrogen that is being produced from oil and gas, it really is with carbon capture and storage, so it is to reduce that carbon intensity and build on the strength of our energy sector in that way.
I'm happy to turn it over to Aaron to provide more details, if that's helpful.
