The last time I looked at hydrogen powered vehicles, they were planning on storing it at 10,000 PSI in steel tanks buried in the trunk. The tank better be well anchored... it could be quite a missile.
Hydrogen is is bunch of BS.
Plug in Electric is the only way to go.
No need for fueling stations, if you have a 110 outlet you are charging it up.
Not going that route. Tech moves on.
