> Nuclear would be good but would make the ships a huge piracy/terrorism target. You'd need military escorts for them. Dunno if this is actually true. There's plenty of stuff going around every day in unguarded ships that have significantly more accessible terror-potential than anything you can put together with a small nuclear reactor. If recent events in the Panama Canal or Baltimore isn't convincing enough of the disruption a single misplaced cargo ship can cause, it's hard to argue against Tianjin[1] and Beirut[2]. Like those disasters, mind bogglingly destructive as they were, were caused by incompetence and negligence. It's hard to imagine what someone with malicious intent could cook up with nearly 3000 tons of ammonium nitrate.
