JB, when talking to the media, you have to keep it simple, you can not start talking about energy content and efficiencies. Simply put, a fuel cell vehicle will go the same distance on 1 Kg of hydrogen, as an Internal Combustion Engine (ICE) vehicle on 2 gallons of gasoline. But its even simpler and just as accurate to say, 1 kg of hydrogen is equivalent to 2 gallons of gasoline.
