To be fair, you need to compare a complete workflow including the renewable production of the jet fuel.
If the overhead of heavy batteries does not annihilate the benefit of the carbon-neutral production rendered possible by using electricity (and associated carbon-neutral sources like photovoltaic etc... heck, even nuclear fission), then batteries are still the path to go.
If there are carbon-neutral ways to produce the jet-fuel, and to have a completely carbon-neutral(or even negative) cycle production+consumption, then why not. If it could be done without turning the Earth into a giant bio-fuel crop, that would be nice.
