Also, H2 is VERY good at escaping things. The atoms are so small.....
So while this means it's hard to build a perfect containment system for
it, it also means that if you only have a very small leak....it's hard
to build up in a normal (not passive house level of sealing) building,
as it can escape the building just about as good as it can escape
tanks/pipes/fittings, etc...
Not saying it's safe...just that very small leaks probably are not
enough to "build up" anywhere. You would need the combination of a
decent sized leak with an well sealed "peak" and an ignition source.

Maybe the Mirai tank system is really tight. Otherwise, I'm really
curious: why haven't there been any reported H2 explosions ?
Could it be partly because they've sold only about 8,500 of them since 2015?
Low sales volume means fewer opportunities for faults to develop.
It would also be interesting to know how many of those sales were to fleets
where the vehicles tend to be parked outside in open lots, and not in
residential garages.
