Hydrogen is also a byproduct of some source of energy, it doesn’t just materialize.
The difference is batteries are vastly more efficient at storage and doing useful work with that stored energy. There’s use cases where that’s fine like rocketry, but efficiency or energy density is usually a dealbreaker.
