The good news is that I think the best applications in other parts of the world are the same applications as in Canada. I think any jurisdiction, globally, that has ambitious emission reduction goals is going to need other sources of clean energy besides electricity.
One of the sectors that is a best use case for low-carbon hydrogen and its derivatives is heavy transportation, as Mr. Lakeman mentioned. Hydrogen fuel cells provide long-haul trucks with the amount of torque, the range and the short refuelling times that are required for those long distances, as well as other types of heavy long-haul transportation. You'll think of trains and marine vessels—especially large ones. Once you get beyond the range of what you can realistically achieve with a lithium-ion battery, hydrogen fuel cells become very important. That's one sector.
A little bit further down the road is the aviation sector. While it may be possible to decarbonize some small, short-haul flights with battery electric technologies, for long-haul flights—think across the ocean—we're likely going to need some combination of sustainable aviation fuel that is made from hydrogen and/or fuel cells. There's actually an organization in Canada called H2CanFly that has support from several large players in the aviation sector. It's doing work in that area right now to figure out how to decarbonize aviation.
Another important sector is industrial applications, especially heavy industry that needs high temperatures. Whenever you need combustion to make things like steel, bricks or aluminum, it's very difficult to do it with electricity. You really need to combust something. That's why natural gas or even coal is important in that sector. In the long term, you can burn green hydrogen or blue hydrogen for those types of industrial facilities.
