Hydrogen is just a means of energy storage. The CO2 is produced wherever you actually generate that energy. No doubt fossil fuel energy is used to make the hydrogen, so there is still a carbon footprint. On the up side, this means that, if our energy economy ever did switch to renewables, everything hydrogen-powered would effectively lose its carbon footprint with no extra effort.
