I do not have any refr. only that it takes a lot of electricity to make hydrogen from freshwater by electrolysis, which has been widely stated as one of several reasons why hydrogen is NOT the future marine fuel. It stand to reason that the same apply if you use seawater as “feed stock” (??)
You have obviously studied this more than me, so I bow to superior knowledge.
I have no real practical knowledge of that technology. I only know a few details from reading reports and papers that are relevant to my current business.

For any fuel to succeed as a Marine fuel there has to be bunkering points around the world:
Waterfront Shipping, a wholly-owned subsidiary of Methanex Corporation, has demonstrated the ease of barge-to-ship bunkering as part of the launch this week of the world’s first barge-to-ship methanol bunkering operation at the Port of Rotterdam....

Unless you go Nuclear, in which case bunkering happen infrequently.
Hydrogen has wider application in shipping:
Hydrogen powered ferries will be coming soon
Green Ships, based in Oslo, wants to build two big hydrogen-powered ropax ferries, to connect Nice, Corsica and Sardinia. Ferry Shipping News understands there is a letter of intent with Fosen Shipyard. (source: Norwegian Maritimt Magasin)The first ship could be ready end of 2022, the second in summer 2023.

International shipping faces full inclusion in EU carbon market from 2026:
Under the draft EU plan, shipping would be added to the ETS gradually from 2023, when ship owners must surrender enough CO2 permits to cover 20% of their emissions.
This would rise to 45% in 2024 and 70% in 2025 and from 2026, ship owners would need to surrender enough permits to cover 100% of their ETS-covered emissions.
If a shipping company failed to comply with the ETS for two years running, an EU country could issue an “expulsion order” to the EU to ban ships owned by the company from the bloc’s ports, the draft document said.

Lots of different fuels are in the running as the Marine Fuel of the Future:
