good question, both have pros and cons, but i thing H² will win in the end. its much easyer to integrate into the grid.
wind and solar work good with H² or synth CH4, but not that good with E-cars. and the loading of a H² car is much faster than a E-car.
but in the end it all comes to the german inustrie, they are the one to choose how we drive in the future, why? because they have the highst r&d expenditures, the best chance of bringing in new tech (its much easyer in costly big cars) and germany is leading with the transition to clean energie. we allready have some small power-to-gas facilitys.we also have a lot of biogas that needs costly upgrading or mixing with clean H²/synt CH4 and enough surplus energie at times because clean energie is volatile.
