Just produce methanol from seawater cheaper than petrol using molten salt advanced modular nuclear reactors, burn than methanol in petrol engines (modifing an ICE to handle methanol cost about 100 USD).

Or in highly polluted cities crack that methanol into hydrogen and CO2 onboard the vehicle and run the hydrogen through a PEM fuel cell. Carbon Monoxide produced from the hydrocarbon would poison the platinum catalyst in the fuel cell stack, but last year scientists in China figured out that adding iron oxide nanoparticles to the catalyst prevented this damage:
