The faster fill-up time of hydrogen was mostly a lie. It could fuel a single vehicle at that speed, but then the filling station would need a significant time to build up enough pressure for the next one.

Turns out having to fill vehicles at 350 to 700 bar (5,000 to 10,000 psi) is a massive pain - especially when you can't keep it cryogenically cooled as a liquid in your storage tanks.
