Hmm let's think about that one.
Hydrogen will burn at a ~4% concentration in air and needs very little catalyzing agents to produce a 'big bang'
Natural gas needs significantly higher concentrations and more energetic catalysts to release it's potential energy.
The sun is powered by Hydrogen and not Methane.
The Hindenburg was an airship filled with Hydrogen and you all know the outcome of that.
Rocketships are powered by Hydrogen, not Natural Gas.
etc etc etc
Reason why NY/NJ bans Hydrogen in tunnels (whether they thought about it or not):
Hydrogen is lighter than air and could collect at the tops of the tunnels and ignite and cause major damage. Out in the open H2 will harmlessly vent to the atmo and have less of a chance of igniting.
