Have you ever seen a hydrogen fire? Of course you haven't because you can't see it burning you, you can only feel your skin turning to a krisp! The danged stuff is entirely too unstable, and volitile!!!
Plus, you can only go about 50 miles max on a fillup and I seriously doubt they're gonna put filling stations every 40-50 miles along Hwy 50 across NV, unless they can combine them with whore houses and casinos... Get offa this stupid Schwarzenrenegger pipe dream of a "Hydrogen Highway" and apply you mind to something feasible... Puuleeze!!!
After reading the Reason report, I wonder about the weight of these vehicles. It said a 6500 lb. Hummer would be about 1000 lbs heavier if equipped for hydrogen (roughly 15%). That's got to have a negative impact (i.e. cost more) in maintenance of highways, etc.
This thing has not been thought out. It is just another push to get taxpayer money to support their folly, with the help of junk-science.
Hydrogen cannot be seriously considered a fuel when it takes more energy to create it than it produces. Which it ALWAYS will.
