If the hydrogen was produced the way described by you, Two Bears, the situation would be worse than it is now. The hydrogen technology only makes sense, economically and environmentally, if the hydrogen is produced by a cleaner and preferably cheap renewable source.

Why not use the renewable source directly? Well, wind doesn't blow all the time and sometimes the sun doesn't shine. Hydrogen is a good and transportable storage of energy which makes it attractive.

Whenever energy is stored there is danger (dams can burst etc.). I wouldn't like to sit in a car with a fluid hydrogen tank or a very big gas tank. Thankfully, there are safer methods to transport hydrogen.
