The production of hydrogen itself in a usable form for a car is the problem.
Most of the hydrogen now comes from splitting the hydrocarbon of natural gas. So strip out the hydrogen and you have the carbon part left. Yea, good old CO2, what happens, to that is the one big issue. So yea, burning hydrogen is pollution free, but making it produces lots of bad pookie CO2.
Or we can use electricity to make hydrogen from water. Then you only have oxygen as the main byproduct, and no bug deal. But what source of electricity is used to make the hydrogen? The only logical choice is nuclear so just left over nuclear waste. Until we figure out fusion, and that has been 20 years out for the last 50 years. Hydroelectric is clean, if you ignore the giant dams and energy needed to make the dam, and the environmental damage of damming a river.
In the end, it takes more energy to produce the hydrogen than we get back from it. Why bother with the hydrogen production, and skip that step and use the energy for the transportation in the first place.
