I take issue with these headlines that say "X is now the cheapest energy in history!" when they mean "at noon on a sunny day in summer, completely ignoring any extra equipment and capacity needed at scale to deal with the fact that it is intermittent"

Hydrogen is not an energy source but rather an energy carrier, like a battery. If you want to use hydrogen fuel cell vehicles that can exchange cells at street stations you need extra energy clean-energy capacity to make the hydrogen. There are still plenty of hurdles.
