Seems like they're storing it in the gas network, does that not scale?
There's enough energy in the gas network today to power the world for a few days, seems like a great way to store excess renewable power.

Salt domes (commonly used to store large amounts of natural gas) might also be useful for hydrogen storage but would need to have their plumbing replaced.
