The question says it all.

I assume it is possible except that it's a bit of a problem to build a tank which can store such huge amounts of gas under high pressure.

I don't see why not. Stationary turbines often run on gaseous fuels (mostly natural gas). Liquid fuel is nice because it can fit in irregular spaces without being under pressure.

Perhaps the temp differences at altitude have some quite negative effects? Have no idea though.

Yes the USSR tried it.



Half the plane was taken up by LNG tank, so it obviously was not a commercially practical idea.

Probably the reason you don't see it is because the weight of the required tanks erases any benefit derived from the fuel itself...propane tanks aren't light
