I thought it was going to be easier for me to answer the question than for Mr. Kirby because he's in the hydrogen industry, but he made the point that I would make. In some instances you're going to use RNG and in some instances you're going to use hydrogen.
I'd also note, further to some of the earlier questions I had, in some instances you're going to push carbon capture technologies.
The fact is that we have three energy delivery systems. We have a liquid energy delivery system, a gaseous energy delivery system and an electron energy delivery system. There are three big ones. We want to find technologies on each that will deliver on the targets you've set. Put in place the conditions that allow markets to compete and different technologies to come to the fore. Let's all be surprised by what we find out.
If you pick a winner, I don't think it's going to be a winner at the end of the day.
