I drove 1800 miles in a Hydrogen Car

From the practical standpoint of time, hydrogen cars take 5 minutes to fill up, battery electric take far longer. Therefore, there is a far greater need for space to have charging points for longer time requirements than hydrogen fuel stations which can service far more people per hour than the equivalent space of electric charging points. 

I think in the longer term of expanding the size of the electric car market, Hydrogen will be scalable far more practically than battery electric, particularly with the impact of large scale battery electric on electrical systems across the world, which are scaled for residential and commercial/industrial usage, battery electric cars on a large scale impact on that output level.
