Would this be a viable option for cruise or cargo ships as well?
The only real green option for oceangoing cargo ships at our current technology would be nuclear plants. Since small nuclear plants generally require highly enriched uranium suitable to making bombs, I don't foresee it being an option, however.
Nuclear cargos exist. Or at least existed. URSS then Russia had one for reach a port in the north. It was an ice-breaker.
Or back to wind.
Idk how expensive these reactors are tho. The US Navy operates dozens in their fleet between CVNs and SSBNs, but that dwarfs the rest of the world.
Thorium Molten Salt reactor can't be used for weapons because it's no fissable so it can't have a chain reaction that creates explosions

Yeah, I wouldn't consider the thorium fuel cycle as part of our current tech. India's going to be the first to start thorium breeding at scale which they haven't gotten close to doing to date. That said, Thorium fuel absolutely can produce nuclear weapons in a breeder reactor design, it's just more difficult because you have to reprocess the fuel for U233 which is what Thorium is bred into.
There are lower enrichment targets you could theoretically use for a small uranium reactor depending on your moderator. It's just easier to use highly enriched uranium, or maybe some sort of MOX fuel.
Not a very good one.
Hydrogen density is too low, there is more hydrogen in things like ammonia or methanol. All of these are potential solutions to fossil bunk fuel or LNG, but all have issues and there is no clear winner yet.
Okay rowing it is.
