In pronciple you should be able to do that by extracting carbon dioxide from the atmosphere and combining it with hydrogen from electrolyzed water. It would just need a crazy ammount of energy to get the carbon dioxide (likely by fractional destilation of air) and hydrogen from water, not to mention making the hydrocarbon chains for gasoline. Using compressed methane could be better (I have seen buses here in Czexh Republic using compressed natural gas, which is basically just methane, very often) or even skipping the carbon and using hydrogen, if you can store it safely and efficiently. But indeed, if you can store the power directly instead of usinfpg it inefficiently to make fuel, thats the best.
