Hydrogen is terrible backup storage, as it evaporates through all known materials. Even as metal hydride or ammonia it's not great. (Density for the first, stability for the latter.) This is why everyone still uses hydrocarbons. Pity they don't make or burn them cleanly.

Hydrogen for backup storage for the grid would be stored underground. This is a demonstrated working technology.

Underground in what? Leaky container or an even more leaky cave?

There is a reason why there are low levels of hydrogen even in oil fields, while there are high levels of methane...

Underground in geological formations. For example, in cavities solution-mined out of salt.

This is a known and proven technology. Despite your pearl clutching, the hydrogen doesn't escape at a rate that would make it unworkable.
