You cannot look at the energy density of the fuel by itself.
Electric motors are lighter than ICE engines per HP and torque unit.
Emrax 268 (electric engine designed for aircraft) - 6.12 HP/lb
GE 90-115B (jet engine used in 777) - 6.10 HP/lb
Junkers Jumo 205A (diesel engine used in Ju 86C-1) - 0.66 HP/lb
Electric also scale down better so for light weight UAV a higher energy density battery will open up a bunch of use cases.
