The problem is that any non-fossil fuel derived hydrogen made from solar/wind loses more than 60% during conversion. Compare that to lithium with around 10% loss that includes outputting the energy (hydrogen would lose even more). Hydrogen is a terrible battery with very little chance to catch up to current battery tech.
