A catchy headline, but H2 is not sold or distributed as a "gas." While Hydrogen is in fact the most abundant element in the universe it abhors being on its own and pairs with itself, hence "H2." H2 is cryogenically cooled to -253ºC/-423ºF and stored at about 150 psi, or about the same as propane. Hydrogen does not exist as a free gas naturally, it combines with other elements like Oxygen.
I don't want to be the rperez of FCEVs, but H2 production & transport, and fuel cell efficiency should continue to be developed to a practical state. IMHO, I think H2 fuel cells are a better strategy long term.
