If they burn fossil fuels to make the petrol then it's worse than useless. Every time you convert energy from one form to another you lose some of that energy as waste heat. To make 1 joule of petrol energy from air and water you need to use >1 joule of energy. So if it's fossil fuel energy you're using then it'sincreasing the amount of C0s in the atmosphere.
If they use nuclear, solar, wind or hydro then it's a closed, carbon neutral cycle.
