How are you going to make the hydrogen?

A kg of hydrogen is energy wise on a par with a gallon of gasoline.
(48 kWh/kg to make hydrogen vs about 40 kWh/gallon for gasoline).

The US currently uses about a million 42 gallon bbls of oil an hour.
To make this amount of hydrogen would take around 1600 million kW, or
1.6 TW.  That's about twice the current installed electrical capacity
of the US and around 5 times the average production of electric power.

And that's before you solve the problems of carrying around hydrogen.
