Maybe I'm missing something. I thought the proposal was to use windpower to crack hydrogen from seawater then compress it and ship it to Europe. No natural gas or pipelines needed.
Not sure about the seawater bit as salt water is much more corrosive than fresh water, so the electrodes will corrode much more quickly. Not only does that mean that they need to ne replaced more frequently, but the process becomes less efficient when the electrodes are corroded. Work is being done to find materials that the electrodes can be made of that won’t corrode as easily but are still efficient but that is still years away.
And I read somewhere that ammonia was what was to be produced and shipped, because while hazardous it’s easier to transport safely, and can be broken down easily into hydrogen at the destination.

Yes, it is very likely that the hydrogen will be converted to ammonia for transportation. Not only is it easier to store (it isn’t corrosive like H2 and is a liquid at STP) but it has a higher energy density than either liquid compressed H2. The disadvantage is you need a facility to convert it back to H2 at the destination (and then compress it). Work is being done to make ammonia fuel cells, which would solve this problem.
