There is no cost effective method for getting pure hydrogen and like the early EV days, no stations which is why hydrogen cars are only marketed in a couple of states. It currently costs more for hydrogen than gasoline. Since demand is low, when one of the few plants that produce hydrogen goes down, it's disastrous as stations run out. People in CA had to just park their cars for a couple of months waiting for fuel to be available again. Just like with EVs, a massive infrastructure buildout would be needed for hydrogen.
Hyundai also has a hydrogen car program. I can see Asian countries going toward hydrogen as electric generation challenges force a choice.
