Real answer: power density. Pound for pound, gas still contains more energy than our best batteries. The weight of energy storage is still a massive deal for anything that cannot be tethered to a grid or be in close practical proximity for frequent recharging, from rockets, planes and cars (sometimes) to chainsaws and lawnmowers (sometimes).
