You should actually read the linked article.

It's relatively sparse on technical details, but it does mention:

- Renewable hydrogen

- Compressed Air Energy Storage

- Large scale flow batteries

- Solid oxide fuel cells

Seems like hydrogen is not actually used as a storage mechanism. They convert to hydrogen on demand to power turbines.

They will be using sealed salt caverns to storage large quantities of gas cheaply.
