Surely with hydrogen it's a fuel cell (and relatively v. small battery for regenerative braking and such), not a battery like a BEV? And as the hydrogen, using a tech like MOF, would be cheaper to store, and easier to store longer term ... the extra energy expense seems a priori to remove a lot of e- waste and reliance on mining in developing nations. I'm not sure how the life-cycle overall energy usage compares, would be interested in reading a study of someone wants to link one. I'm hoping that hydrogen storage will become easy enough that we'll use that for large scale excesses like those from nation-size grids during excess production. So we can do seasonal shifting at scale.
