I assume they'll eventually find use in aviation or maybe trucks and heavy machinery. But for passenger cars this seems to be a lost cause. The tanks are huge, so in practice range of hydrogen cars isn't any better than BEV's. The biggest pain of BEVs is lack of reliable public chargers everywhere. But there are far fewer hydrogen stations, and they aren't any easier to build and maintain! And you can't make high pressure hydrogen from a home outlet, so there isn't even a backup.
