The Pickens Plan: Where Are We One Year Later?

Fuel cells are not zero CO2. Their operation is, but not generation of hydrogen (most of which comes from natural gas today). The fuel cells are expensive (6 figures is standard for something that could power a car), the storage and transportation of H2 is still problematic. We'd need multiple practical breakthroughs before we could start making a manufacturable car. We can't wait 10-20 years for that to happen.
Plus, on an EROEI perspective, it makes more sense to store electricity in a battery than to turn the electricity into hydrogen, transport the hydrogen, put it thru a fuel cell and get back some of the original electricity to power the car.
I was once a fuel cell believer, but became educated and realized there are better alternatives.
