Sadly, the Orkneys could provide even more renewables if Scotland would build a larger export cable. Instead, the islands are forced to build hydrogen plants and turn off wind generators. Last I checked, they were at 108% renewable.

It does mean some interesting work is being done using hydrogen as storage, and for the ferries (not sure how far along the hydrogen ferries are).
