Hydrogen is great but it's very difficult to deal with. Unfortunately hydrogen it seems is not a panacea. See here for the lowdown.
Storage: Having to compress it to 700bar and store it is a massive challenge and expensive af. The smallest atom in the universe likes to seep through stuff.
Emissions: currently 90+% of hydrogen generated from flossil fuels so dirty hydrogen won't solve the geenhouse gas problem
Clean hydrogen: generated from wind and solar is great but wind and solar is unstable power
Fuel cells: Due to the water byproduct they like to freeze in winter time. They also require platinum and iridium one is rare and the other is even more rare. These are much more rare than lithium. Also they require mining
So in short hydrogen requires mining both for much rarer metals and for natural gas/coal etc, is difficult to store and therefore costs are not going to be optimal and is mostly..currently...dirty hydrogen. There are massive challenges ahead in order to get hydrogen up to scale while keeping the costs down.
