what you are missing is:
1. Keeping the hydrogen at high pressure requires a lot of energy.
2. Hydrogen produces H2O in gas form, which in itself it is still a greenhouse gas.
3. True, hydrogen can be produced by "green" technologies, but what is the energy lost throughout the procedure? It is quite a loss (about 20%).
Moreover, it is theoretically viable to produce all electric energy via renewables, albeit impracticle and 100 years away. Thus, I can't see how saying that """EVENTUALLY""" hydrogen might be renewable is good for the environment.
Hydrogen is good for a very niche part of our production system (and spoiler it is not car industry or house heating where better alternatives already exist[1][2]).
