Sure but you should be comparing the goal end state, a world in which out energy consumption and generation is green, that's the whole point of our move to bev's and hydrogen. So you should be comparing energy generation by green means to power a BEV or using green energy to produce hydrogen to power a hydrogen car. In that world the whole energy production and consumption chain is about 3x as efficient for BEV, which in my mind means there is no way hydrogen is going to be competitive and we shouldn't waste valuable resources on persuing it.
