You worry too much. If this Hummer's gas tank consisted of a large
volume of gas in a fragile, flammable envelope the size of a townhouse
complex, I might see your point.
Hydrogen, in a conventional compressed-gas cylinder, is about as
dangerous as natural gas, propane, or gasoline. Probably more dangerous
than diesel, except that diesel claims a fair number of casualties each
year by being spilled on the road and wiping out cyclists and
motorcyclists (it's slippery and doesn't evaporate quickly).
Stuff can go wrong with any of these fuel sources, but hydrogen has a
lot to recommend it from a safety viewpoint. When a tank is ruptured,
gasoline both puddles and vaporizes. Propane (and CNG?) is heavier than
air, so it pools around the rupture point. But hydrogen, once it
escapes, goes up and away as fast as it possibly can.
Locally, there are a fair number of CNG and propane powered cars rolling
around the roads, and they don't seem to blow up very often.
