I would argue that.
If you stated "fuel", then your argument carries more weight.
I think most peeps, when they hear "gas" assume (yes, I know what that
may also mean...) you mean gasoline/petrol.
When you say "fuel", yes, there can be a mix up.
Heck, coal is a fuel, don't think anyone is shoveling coal into an
aircraft.....LOL.......

Yes, LiFe is a lot different than LiPo or LiOn.
LiFe is a lot closer in safety to LA than other Lithium chemistries.


What's so funny about shoveling coal into an aircraft?

....and somewhat to my surprise, I found out that anthracite and
bituminous coals have about the same energy density (MegaJoules/litre) as
diesel, petrol or jet fuel. Less surprisingly high quality coals are
50-75% worse for specific energy (MegaJoules/Kilogram).

IOW a 'tank' of coal will have more or less the same energy content as
the same sized tank of jet fuel or diesel but will be quite a bit
heavier.
