Deep Purple. Wind. Hydrogen and seabed storage

Innovation Norway has granted financial support to the Deep Purple project, which is developing a green hydrogen production system powered by offshore wind, with the hydrogen being stored on the seabed.

with the hydrogen being stored on the seabed

This part caught my attention-- what's the benefit of this? The hydrogen presumably needs to make its way to the shore to be used, so how does storing it at the seabed for a period of time before going to where it will be used create an advantage?

Matt, given

  1. Wind turbines are incapable of generating any significant amount of hydrogen by electrolysis, and
  2. Norway is already powering oil platforms with electricity from wind turbines - 

let's consider the possibility dirty hydrogen, made from natural gas extracted on Norway's oil platforms, will make up the lion's share of any hydrogen "stored on the seabed" - with such a storage location used to hide its provenance.

Not that a nation with an economy powered by $1 trillion in North Sea oil production would attempt to greenwash fossil fuel, or anything.

Presumably it will reduce project onshore land take Matt.  Should make it easier to export globally as fewer interfaces- but many ports are looking at expanding their hydrogen storage offers and they may miss out.
