Now look it up for hydrogen.
Luckily no fool would consider that as a fuel or anything.
100% agreed, the use of hydrogen as a fuel is the dumbest thing since radioactive health foods. It burns explosively very very quickly at a very wide range of air-fuel mixes.
When I was in the welder repair game, our parent company was BOC gasses.
I would occasionally go to their main depo to do various work related to welders and was told about (and saw) their on site acetylene production and hydrogen storage.
They had a semi-trailer with a bunch of long tanks (3 across, 2 high IIRC) and as long as a full length trailer.
Apparently if that thing went pop, the damage radius was about 2 kilometers in every direction... Total destruction was multiple hundreds of meters.
Good stuff that hydrogen...
