Fuels & energy
Compare what fuels contain and how much chemical energy they store.

Lower heating value (LHV), from DOE AFDC. Useful output is a calculation using your assumed efficiencies, not a vehicle-performance prediction.
1 kWh = 3.6 MJ. Stored energy is not useful work; conversion losses matter. Composition, storage and lifecycle emissions also matter. Fuels are not interchangeable.
