So when you make hydrogen, you're using natural gas. That's been a bit of a problem because the price has gone up. So then coking became more popular because of the pricing issues.
But is there any sense that we could look at the development of hydrogen from clean energy, rather than through using natural gas? Could you use perhaps electric, perhaps wind, perhaps some other forms of energy that would provide some kind of carbon dioxide relief to this very valuable resource we have in the tar sands?
