Energy production is one thing, but storage another and also energy density of that storage. Especially when talking about transportation.
Airplanes need to be light; powering them with liquid fuels is great because they are very energy dense and also the airplane gets lighter as it goes. Not the case with batteries.
Similar issue for ships like cargo ships - space is valueable there, you can not waste 50x the amount of space for batteries compared to fuel.
In the transportation sector liquid fuels will be there for a long time. Perhaps we manage to make them non-fossil though.
