I've heard this argument tons of times.  And, what I come back to is
2 possibilities.
1. Use electrical power to electrolize water with H2SO4 as a catalyst
or,
2. I've been told that there is a large, naturally replenishible
supply of hydrogen pockets in the earth's crust.

I don't know which is better, but it might not be long before people
are drilling for H2 instead of oil.
