Elon is ok with his position for not using hydorgen in his ars, he may be regretting it with the semi.
BUT as an energy storage it is far better than megapacks if you need to transport it somewhere else, keep it until needed or rapidly refill it.
So far Tesla has been successful in getting their charging stations installed, he has to have a really good real estate team or is just installing class 2 charges and nothing faster.
Both Tesla and NIkola have "mobile charging" units for their BEV to be used in depots but can only charge one or two rigs at once. they then need the other 20 hrs to recharge from the weak grid supply.
REII (and others) have the solution for this being ale to drive many fast DC chargers independent of the grid supply. if you want mor chargers install more REII units.
Hydrogen is the energy they use to drive those chargers.
Oh and they could also refill hydrogen trucks and cars for another revenue stream for the operator.
REIIs portability I think we will see is only a fraction of their business plan - it's great to get attention but they can deliver a containerized not trailer solution.
