Hydrogen is a hell of a lot safer than gasoline, as anyone who has experienced a fire fueled by one or the other could tell you.* Unless continuously replenished, a hydrogen fire lasts only seconds, assuming the gas does not disperse before it is ignited. Not true for a pool of gasoline.
The Hindenberg is a red herring in the safety issue. Most people now believe the materials comprising the airship were a much greater flammability risk than the lifting gas, and an earlier airship, the Graf Zeppelin (a three-foot model of which hangs from my ceiling), clocked over a million miles of accident-free passenger miles, including trans-Atlantic flights and a trip around the world before eventually being scrapped for WWII materials.
*The one bad part about a hydrogen flame is that it tends to be invisible.
