There's a possibility that if a hydrogen tank with 10,000psi exploded in a wild fire that it would starve the fire of oxygen. Hydrogen's fire ball rise very rapidly. Also there will probably be an emergency release valve on the tank to discharge it. The hydrogen could be safely ventilated into the atmosphere in such a situation before the fire reached it. All in all, a far better position than dealing with 10,000+ gallons of gasoline in the same scenario. Also build the facility in a clearing with break walls.
A hydrogen blast in a wildfire would not be a problem.
First of all it would probably be safely underground.
Second I know I wouldn't be hanging around during a wildfire.
Third I live in the northeast where wildfires are not an issue
Fourth if the tank did explode it would probably blow the fire out.
But in general I don't think explosions are an issue. I don't think that is how most tanks fail except potentially in a car accident. So if they fail from a leak it is safer than propane. Hydrogen goes up, propane settles to a low spot, potentially into someone's basement where a heater may ignite it.
