Adding to that, they are now looking at local hydrogen production from wind excess.

While not nearly efficient as using the electricity directly, it's more efficient than throwing it away.

Also the offshore farms sit in a pool of the raw material ( water ).

They produce hydrogen from sea water? I had assumed fresh water sources, but I suppose salt water on an absolute scale is not that more loaded with particulates than anything else.

for record, best electrolysis for hydrogen is a 50% efficiency end-to-end conversion.

Yep efficiency isn't great - but as I said, better then the efficiency of throwing excess away ( zero ).

There is also value in the ability to store the energy - not as efficient as something like using water to store potential energy ( ~75% ), but there is value there.

I'm not somebody who thinks it will be hydrogen everywhere - frankly electricity is easier to distribute and we already have a good infrastructure - but that's not to say it doesn't have a role.
