I thought they were talking about electric ocean liners?

Not in this article, in general.

Batteries don't lend themselves to boats unless they have generators.

Maybe hybrid ships recharging their batteries works but I doubt it.

Electric ships have to have generation somewhere. You'd have to do a lot of work to ruggedize solar panels to handle the travails of the sea. Wind power might help some.

Nuclear power works for US aircraft carriers but it's expensive as hell compared to Bunker fuel and a big ole engine

We're working on fully electrifying our ferries here in Seattle. Plan seems to be limited by current tech, so boats will have some typing up done while loading new cars and passengers on, meaning very high current chargers (kA), which is technically novel so far as I can tell.

Ah ferries - yeah I remember seeing that too, now you mention it.

I was thinking ocean faring vessels. Big cargo ships are the big polluters and idk how they'll pivot

It looks like it only manages to do 300 miles in a river.

Good... But not the bulk of all shipping.

Getting river boats to go green is a good step though.
