Yeah hydrogen!!!
You do know that the fire was the very flammable outer shell going up, right? Hydrogen burns clear.
There is no comparison with the Hindenburg!
Scared of hydrogen, but you are not scared of GASOLINE?
Ever seen videos of propane explosions? The shock wave looks like a nuclear detonation. (or nucular for you W fans).
Here is the recent hydrogen station explosion in Norway aftermath.

BIG DEAL! A gasoline or propane explosion would have been exponentially worse.
Actually it wasn’t an explosion.
“On 10 June 2019, a hydrogen filling station in Norway caught fire. While several media talked about an explosion, the electrolyzer manufacturer involved, Nel, stated that leaked hydrogen gas caught fire in the open air, causing a shock wave.”

“Hydrogen fuel cell vehicles and electric cars are safe. Dont believe scared people. They are not going to burst into a cloud of fire every time you hit a curb. And they will protect you quite well in case you do get in an accident.”
“The train is made of fuel cells that create electricity through chemical reactions that are made by hydrogen molecules that are found in water. This means that it does not emit any carbon dioxide, only water droplets and steam. You also do not need to worry about its speed because this new train can run at 140 km per hour.”

Hydrogen as a viable fuel is a reality.
