It’s hard to replace jet fuel because the alternatives aren’t energetic enough, are too dangerous, or aren’t yet being made at scale.

To learn more, start your googling with these keywords:
Jet fuel – a liquid petroleum fuel with high specific energy and energy density, used in airplane jet engines, made of kerosene with a few additives
Specific Energy – how much energy something contains per unit mass
Energy Density – how much energy something contains per unit volume
Synthetic jet fuel – a jet fuel replacement, typically aiming to have lower life cycle environmental impacts than jet fuel (AKA: sustainable aviation fuel (SAF), alternative jet fuel, renewable aviation fuel, renewable jet fuel, biojet fuel, sustainable alternative fuel)
Kerosene – a petroleum product that is the main component of jet fuel (and old fashioned lanterns)
