Cost would be an obvious factor. An inefficient electricity derivative fuel is always going to be more expensive than charging a battery directly from all that cheap/plentiful renewable electricity eliminating the "middle fuel". Especially when vehicle usage curves have a beautiful inverse to electricity demand curves and vehicles are generally parked for hours when electricity rates are at their very cheapest.
