I think the method of choice to do this would be, hydrogen would be pulled from ocean water in a refinery. Then pumped into cars that have a fuel cell and by product of fuel cell is water. The running on water directly I don't think a car could hold enough water to convert and have decent travel mileage. Secondly the machine to pull hydrogen is very big and uses alot of power. I dont think they could fit it in a car and there wouldn't be enough surplus energy from the process to keep it breaking down the water molecules.
