You can use the same electricity you'd use to charge an electric car to separate water,
With a huge power loss, even if you just look at the hydrogen production and not the transport, storage and maintenance of the specialised facilities necessary to distribute it.
Hydrogen is super inefficient compared to electric vehicles.
The lightbulb cartell existed, but it wasn't like we could have had lightbulbs that would have lasted longer with the same efficiency and light output.
