Sure, I'm happy to.
Mr. Estabrook gave a great overview of the key end-use sectors for hydrogen. I can't add a lot. We certainly have been starting with heavy industry—again, refining chemical production, where it's already been used for decades. Then we'd look at new sectors and industrial sectors as well. You mentioned sustainable aviation fuels. Glass and cement are a couple of other ones. We don't necessarily have.... We have a cement plant that's decarbonizing, but not through hydrogen. It's through carbon capture and storage. In other jurisdictions, that may be the case, like with glass manufacturing as well.
A couple that didn't get mentioned.... You may have mentioned rail. Certainly rail has been a big success story here with the CPKC locomotive program. It started in Edmonton and Calgary, expanded across British Columbia and I think it's now expanding into the United States. That's an ideal heavy-duty transportation application for hydrogen that we can build off of for sure.
There were a couple that weren't mentioned. We know that the defence sector is looking at its own energy requirements, and it thinks hydrogen can play a very significant role. There are some unique applications around drone technologies and other military applications. I think some of the Canadian hydrogen expertise could well be applied in defence. Data centres still seem to be a little on the expensive side for using hydrogen, but I think there may be some niche applications for hydrogen with data centres, particularly for the backup power requirements that a data centre may have. I think those are some additional ones to round it out.
Your question was on the markets internationally. We're certainly focused mainly on the Asian markets—really, Japan and South Korea. They certainly want a secure, stable provider. The main comment I would make is security of supply.
