Just spitballing here, please pretend I'm some rando on the Internet and not some kind of expert.

On its own, there's not much wrong with it. It takes a little longer to fill than a normal gas dispenser, but not bad. But you'll still need to put hydrogen fuel stations everywhere similar to gas stations now.

Hydrogen's biggest competitor is pure electric. I love my EV in part because I can charge at home. There's just something really nice about waking up to a full battery every day, and realizing you haven't been to a gas station in months (I have an ICE as well, but it's not my daily driver). Having to go to a fueling station every week or so again would feel like a big step backward, especially if we need to create a from-scratch infrastructure for it. We already have power lines pretty much everywhere, and can generate power relatively easily, so much of the hard part is done.

Going back to range: in theory this problem could be alleviated if the range were enough that one had to refuel less often, but going through all that trouble to be in a similar situation to what you've had, when a better alternative exists? Nah.
