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?
In: Engineering
Hydrogen is not a power source unless it is produced from fossil fuel, otherwise it is just an energy storage. You can’t “synthesize” it without having another energy source at hand.
Nuclear is problematic because for many of the same reasons cargo vessels don’t have armed guards to deal with pirates as standard, it reduces the number of possible ports of call because countries don’t want foreign armed forces/nuclear reactors in their territory.
