Heavy trucks will eventually run on hydrogen. Hydrogen refuels like gas or diesel in a short amount of time. And the energy density of hydrogen per unit weight is many times that of lithium batteries.
Very unlikely. Hydrogen is hard to store, it is very low density and you just cannot get much in a tank. There have been efforts to find some material which will store it at higher densities but if they have succeeded in producing a practical material I haven't heard about it. \
Hydrogen is also very difficult to ship because it will go right thru normal steel and as mentioned it is low density. There so far is no cheap way to produce Hydrogen either.
This is just greenie pie in the sky information
Old fossil fuel hardheads can choose to live in the past with their head in the sand but hydrogen is already here. Generated by cheap renewable energy, low cost since there is much curtailed solar energy.
LA is going to have a large hydrogen storage and generation facility in Utah, storing hydrogen in salt domes:
