I think hydrogen storage is fine right now, you don't need to store it within the lattice of precious metals or R&D fuel cells. You dump it into a giant thermos and it doesn't all evaporate away for 2 weeks. you can also use direct methanol cells and slectrolyte cells to store hydrogen. Los Alamos has been doing about 30 years of R&D. The heat of combustion of hydrogen is terrible compared to giant hydrocarbon chains, but it's workable. People would rather worry about what happens when you leave your car unattended for 2 weeks in an airport parking lot than consider hydrogen though. And infrastructure changes are a bitch.
If someone made a hydrogen car that could go 0-60 in 3.5 seconds it would be pretty badass. But, currently, I think the fastest hydrogen expo car is a 232 HP 6L V12 that can do 0-60 in 6 seconds, and maintaining a liquid hydrogen powered V12 would be sooo easy
