Of course it is not a high percentage yet, but there are companies like FMG / Future Fuels industries have developed conversions for dump trucks and rail.

Ferries in Norway running fuel cells. Bus companies in the US running fuel cells for some time already.

Battery is great, but not always practical on a larger scale. Elon fanboys all rave that battery is the only solution, which is why technology development stalls due to opinion based investment influences.

I am not saying battery will replace everything. The things where battery alternatives aren't viable would be replaced by bio fuels or e-fuels. Transporting and storing hydrogen is complicated you either need very high pressure tanks or cryogenic storage to get any useful energy density out of it. A few trial runs don't prove economic viability, they prove technical viability. The latter is relatively very easy to achieve.
