Hydrogen will be important, just not necessarily for personal vehicles. But it still could be, if battery cost bottoms out. A hydrogen/fuel cell car weighs much less than a battery car, or even an ICE car. Making H2 at home may end up more practical than charging your battery at home, particularly if your car is away from home when power is free. Facebook was an obvious yawn even in 2005.
