So it would work for our heavy trucks?

More viable than for passenger cars IMO due to the volume availability, but still I think hydrogen has too many problems to be overcome. It's more efficient to extract energy from hydrogen with a fuel cell to produce electricity and drive an EV than it is to combust it in an engine, so it's kind of an unnecessary wasteful conversion step assuming EV charging speeds continue increasing as they have been. There would still be the problem of building out infrastructure to handle hydrogen and distribute it all along our roadways. It's also dangerous.

I really like the idea of using hydrogen, but I think it is only viable as grid storage for excess wind/solar/wave/whatever output. As of now wind turbine output for example is often curtailed because there's no cheap way to store it. And although handling hydrogen is expensive, at scale it might be able to compete vs lithium batteries or other storage methods. It's not all that efficient to electrolyze water only to run the hydrogen back through a fuel cell, but if the energy would be wasted otherwise then it's a net gain.
