Hydrogen will do what nuclear power has already done -- displace oil as an energy source; saving it for petrochemical feedstock. Replacing gasoline will happen when the consumers are faced with high enough prices for gasoline that make other fuels viable options. Someone has to break ground to make hydrogen a viable alternative. If it is too expensive, don't buy it.

....displace oil as an energy source;...

Where are you gonna get the energy to make, store and distribute the hydrogen? Have you done and energy balance to compare hydrogen to fossil fuel? How does it compare?

Arghhhh. Hydrogen is NOT an energy source. It takes more energy to make the hydrogen from water than you get back when you burn it. It is a battery. To make hydrogen, you will have to burn fossil fuels or have a huge nuclear energy industry.
