Ammonia is a better fit for marine applications, as it doesn't require high pressure or cryo storage. It can also be produced using renewable energy, and is cheaper to transport.

One of the largest producers in the world (CF Industries in Louisiana) has committed to producing it using offshore wind, and renewables in general (and their terminals are located in geographic areas where there is already high penetration of renewables on the local grid).

Cryo/pressurized storage isn't technically necessary for ships either. Liquid hydrogen with insulated storage works well enough. The key is evaporation rates. As long as the ship consumes fuel faster than it evaporates, there is no need to maintain pressurization.

In practice, some buffering pressurization may be necessary, but the scale of pressurization needs will be a lot lower than is required to store hydrogen long term.
