Yes. In order to deploy trucks or other commercial vehicles like buses with either hydrogen fuel cells or dual fuel engines, you need the refuelling infrastructure. You need those stations.
What's interesting about hydrogen is that the best applications are in heavy transportation, not in passenger vehicles or light-duty vehicles. The easiest way to start is with heavy trucks and buses that return to base at night. You think of a transit bus. It's operating on an urban route. They fuel up in the morning. They're out on the route all day. They come back at night to the same place. You only need one fuelling station for that. It's the same as heavy trucks that have a route and then come back to a depot at night.
Refuelling those types of heavy transportation vehicles is a lot more feasible than trying to build a network of fuelling stations from coast to coast, as we're experiencing with battery electric vehicles as well. It's not hard to do, but it's really complicated.
