One of the things that gets me on the "hydrogen bandwagon" is the
claim that they need to get research money to develop cheaper fuel
cells. But if we DID have a good source of hydrogen, we don't need
fuel cell cars. Adapting an engine to run on hydrogen is not that
much harder than adapting it to run on NG or LP. It is very low
octane, but exhaust gas recirculation (steam) takes care of that
problem.

Ford and at least three other major manufacturers are showing
hydrogen-powered IC-engined cars at the car shows now. Ford, particularly,
sees it as the interim technology that will bridge the gap until fuel cells
are ready.

But IC engines are, at best, around 28% efficient. Fuel cells for cars are
around 90% efficient. For stationary applications it's even higher.
