how much hydrogen do you need to store though? it doesn't make sense in cars to me, but water-based vehicles seem like they wouldn't need to store problematic amounts given that they have access to h2o

That would imply the ship has the requisite power generation on board to produce hydrogen from water, in which case it would be more efficient to use that power to propel the ship.

So, yes, the ship would have to take all the hydrogen it needs with it.

oh. I thought we were talking about sails to make electricity to run electrolysis to make hydrogen to run engines. storing enough hydrogen for an entire voyage seems prohibitive to me, but I've not done the math
