    Efficiency still matters significantly with hydrogen solar panels, because solar panels aren’t free.

    Suppose solar to wheel is 60% efficient in a battery electric vehicle, but 30% efficient in a hydrogen vehicle. You need half as many solar panels to power the battery electric vehicle, and spend at most half as much to charge it. That matters.

      It really doesn’t when the hydrogen you’re burning isn’t creating pollution like the mining and destruction of the earth that lithium batteries create.
