#2Yup - hydrogen is a really good coolant, it's just explosive in air. Also popular in Stirling engines for this reason and its very low viscosity.

Just wait until you hear about this explosive fuel called "gasoline" that is quite popular for powering cars too

Not really - hydrogen shoots straight up into the atmosphere, whereas petrol both pools in the area and also turns to gas and mixes with air quite easily (which is why it's used as a fuel in the first place)
In practice, hydrogen cars are quite safe. They're just not worth the cost in infrastructure and lack of efficiency compared to BEVs.

Right since we haven’t already used an equal or even more so flammable substance for the past century
As far as I’m aware gasoline ignites at much lower mixtures of oxygen than hydrogen. The Hindenburg can’t hurt you and if it was filled with gasoline vapors instead of hydrogen, well it would never get of the ground, but it would have been more dangerous.

Gasoline is an easily-contained liquid. Gasoline-vapor/air mixtures explode under relatively limited circumstances. Vs. hydrogen is a difficult-to-contain gas, the concentration range for hydrogen/air to be explosive is extremely wide, and triggering the explosion is extremely easy.

Nope. Hydrogen is not just flammable, the article tells you it is EXPLOSIVE at concentration of 4 percent to 74 percent in air. If the Hindenburg was a hydrogen-air mixture, it would have leveled a large portion of the area rather than just burning where it fell.
I've worked in areas where they were developing hydrogen fuel cell vehicles at major auto makers. The facilities are equipped with collectors, detectors, and alarms, and everyone knows to GTFO if the alarm goes off. Hydrogen leaks indoors are extremely dangerous.

Hydrocarbon-air mixtures are also "EXPLOSIVE". See, e.g thermobaric weapons.
Possibly what you're trying to say is that it's easier to get the air in? Or that it's stored under pressure?
