It's not poo-pooing Hydrogen because of envirowackos, it's poo-pooing hydrogen as a means of getting us off of fossil fuels.
Hydrogen is a means of storing energy, not making it. The #1 source of Hydrogen for fuel cell automobiles is from petroleum.
Neither solar, wind, or geothermal electricity is anywhere near efficient enough to provide enough energy for our transportation needs, so unless I see 20 new Nuclear Powerplants per week being started in the US, I will continue to poo-poo Hydrogen fuel cell automobiles as a boondogle.
We should be building more nuclear plants, not only does it create jobs, but will help the US get off OPEC oil, a win-win situation for America.
