... for hydrogen
you are limited to the distribution system that has yet to be
implemented except on a small scale. Electricity is easier to
transport and the electric farm you list below is one whale of a good
start. Unfortunately our power grid is only capable of *almost*
meeting peak demands. Cars user far more energy so that would mean
either trucking vast amounts of Hydrogen, increasing the size of our
electric grid several fold over what we have now, or a combination of
both with the latter being the most likely ...

Why transport the hydrogen? Just produce it electrolytically at every gas
station.
