Producing and distributing hydrogen requires significant infrastructure that releases vastly more CO2 than moving lithium around for EV’s. I think you got blinded by thinking of hydrogen as green but it doesn’t magically show up.
Also, moving lithium around releases negligible CO2, an EV battery only needs 15 pounds of lithium and lasts 25 years. You can work out the exact number based on specific origin and destinations but it’s on the order of driving an ICE 1 to 10 miles. Which shouldn’t be surprising because boats are very efficient, lithium is light, and cars weigh a lot.
