Most of the hydrogen on market is made with methane.
EVs use whatever source is being given, and most of these sources are converting to renewables.
Not comparable imo.
It's also worth noting that EVs can be charged at home. Fast charging isn't necessary for most and it's silly to pretend like hydrogen doesn't need its own distribution network. It's a lot more complicated to set up a hydrogen refilling station than a fast charging one and you can't fully fill your hydrogen over night by plugging it into your wall outlet.
