Thank you for your question.
I believe, as I mentioned earlier, that heavy-duty mobility is really where hydrogen provides one of the most attractive value propositions. I think the high energy density of hydrogen enables a lot of energy to be packed on those vehicles.
If a vehicle operates for long hours, such as a transit bus that is on the road from 5 a.m. to sometimes 11 p.m. or a truck that covers a very long distance, or a train, those vehicles need a lot of energy. Hydrogen provides the energy storage that is required and delivers the range that vehicle operators need.
As well, as was highlighted earlier, the quick refuelling enables those vehicles to be.... Those vehicles are more expensive than a regular vehicle, so you want to utilize those vehicles as much as possible. You want to operate them in multiple shifts. Hydrogen allows you to do that. This is really where we are focusing today. It's in that heavy-duty mobility segment. Those vehicles produce more emissions proportionately than a car that might be used only one hour per day. I think if you want to have the biggest impact on vehicle operation to enable the transition to zero emissions, as well as address GHG emissions, this is where the sweet spot is. It's what is recognized. If you look at every hydrogen strategy published by more than 30 countries in the past 18 months, you see that they all highlight that for transportation—and there are other sectors—heavy-duty mobility is one of the sweet spots.
