Right but this is an article about jet fuel.
And batteries right now weigh around 50 times more for the same energy density as jet fuel. Even taking into account the efficiency differences between electrical powered props & a jet engine. Its still not even close.
On a car this is not an issue, it doesn't need to take off and it can always stop to recharge.
Right now battery tech isn't close to being able to replace aviation fuel. Which leaves either bio fuels, or an alternative like Hydrogen.
