Why don’t we have Nuclear or Hydrogen powered cargo ships?

276 viewsEngineeringOther

As nuclear is already used on aircraft carriers, and with a major cargo ship not having a large crew including guests so it can be properly scrutinized and managed by engineers, why hasn’t this technology ever carried over for commercial operators?

Similarly for hydrogen, why (or are?) ship builders not trying to build hydrogen powered engines? Seeing the massive size of engines (and fuel) they have, could they make super-sized fuel cells and on-board synthesizing to no longer be reliant on gas?

The insurance rates of a nuclear powered cargo ships must be insane. The potential liability of an accident with such a ship is not something a shipping company can survive. There are few insurers that can survive it. I suspect there’s prosperous countries that wouldn’t survive it.
