As I recall compressing and storing hydrogen is a very expensive process. One problem is that hydrogen likes to destroy most metals. Any piping, compressor, or container must be made of expensive metals or lined with glass or something.
While this is true, the really expensive part is the high-pressure tank. It has to be fairly extreme to actually hold the hydrogen, let alone the issue of sealing it against the gas which is basically a solved problem.
In any scenario where the whole plant is surrounded by seawater and the hydrogen is going to be used right there and doesn't need to be transported anywhere else, you could use the sea itself as your pressure vessel. Provided the glass or other hydrogen-safe lining is strong enough to support its own weight then the increasing pressure inside could be matched by the pressure outside by lowering the tank deeper into the sea. (About 10m/bar)

I heard that called "bebugging" in the 70s. Still seems like a good idea.

Amazing transformation. When I worked on it 15 years ago, it was a DOS/VSE clone.
It's simple: Beowulf was English.
