Yes, but we still have to change all cars in the country, build new infrastructure in all gas station.
Besides, we dont know how to get pure hydrogen without using as much energy.
Hydrogen is for the future, bio-fuel have none of these problems.

biofuel increases food costs in huge numbers. consumers will notice (and already are).

What increasinf the price of food is a bigger demand from China, India and good part of emerging countries.
The decreasing value of dollar plays a role in this problem also.
It is reality already, by the time we start to use ethanol and bio-diesel at large scale these options will be ready.
We have nothing to lose by switching to bio fuel now.
