Enh, it won't matter, the hydrogen infrastructure just isn't there in the US, and won't be for a long time. We simply can't replace enough of our energy needs with hydrogen fast enough.Bio-fuels arethe way of the future for automotive apps. And I think the Aluminum/Air fuel-cell will see more development in the next decade for electric cars in addition to portable electronics and even home power sources.

 

I can't wait for someone to build a fuel-cell powered turbo diesel hybrid. Can you say 100+ mpg city, anyone? Diesel engines (when tuned right) can run on anything that burns, making them the perfect platform for alternitive fuels, and if you couple that with a hybrid drive system, it will be so efficient that people won't be able to afford not to drive them.
