    Except those fundamentally limits are far higher. The fact is that hydrogen stores energy at 120 MJ/kg. Even at 5% weight efficiency, that’s 6 MJ/kg. Or 1,666 Wh/kg. Far beyond any battery.

    Your link is seriously lying. 8x is the gap between lead-acid and li-ion batteries. The claims are simply impossible. The author must be unknowingly comparing lead-acid battery powered cars to li-ion battery powered cars. I cannot see any other way his claim is true.

    A lithium-air battery is literally a fuel cell. In fact, what did you think hydrogen fuel cells were this entire time?
