For 78% of America - there will be no need for more energy (better batteries) to accomplish the daily commute. That is the point. For those occasions that we need to go further than the battery will take us - we can simply use E85 or even just plain old gasoline (infrastructure done). Again - PHEV's are not for everyone or every application - but if 78% of us can use zero gasoline - why would we wait 10 - 15 years and invest BILLIONS of dollars in an infrastructure to support hydrogen. As battery technology improves (this is really only the first or second generation PEHV technology) fewer and fewer people will need to use fossil fuel.
As for your "energy" question – a single grain of sand contains way more energy than the a hydrogen fuel cell can get from a tank of hydrogen (E=MC^2). Does it make sense to try and develop that capability? Should we continue to buy oil from the Middle East until we do?
I’m not trying to be argumentative. I would just like someone to help me understand why we should wait and invest Billions in a hydrogen infrastructure? Why Hydrogen?
