Good point. I was stuck thinking of ambient temperature onlyWhat you can do is to heat the gas to make it expand. Same mass takes up more volume creates more lift. Think it was Archimedes who first identified the buoyancy effect. Heating up helium is safe enough but hydrogen? I do that in my catalyst lab, but folks “don’t try this at home”.
