There is already fabulous way to store hydrogen that works well and is used every day. You synthesize organic molecules to make long chain hyrdocarbons and benzene rings and put it together into complexes of varying viscosities and volatility. It’s called petrochemicals otherwise known as fossil fuels. They are relatively safe, easy to store and transport and have very high energy density - higher actually than explosive compounds - which are burdened with carrying their own oxidizer.
And we already have industrial scale plants that can synthesize these kinds of chemicals from coal.
Snicker... you’re my hero.
