I haven't heard the British-English idiom "to cry stinking fish" used in American English much, but it may be very appropriate to this report.
Norway’s Hurtigruten, best known for the ships that ferry tourists along the country’s fjords and coastline and up into the Arctic, is investing 7 billion crowns ($826 million) over three years to adapt its 17-strong fleet.
Six of its older vessels will be retrofitted to run on a combination of liquefied natural gas (LNG), electric batteries and liquefied bio gas (LBG).
“We are talking about an energy source (LBG) from organic waste, which would otherwise have gone up in the air. This is waste material from dead fish, from agriculture and forestry,” Hurtigruten CEO Daniel Skjeldam told Reuters in an interview.
“Our main aim is to improve and cut emissions,” he said.

I'm sorry, but the thought of a ship powered by dead fish is just too bizarre to contemplate. I certainly don't want to smell its funnel smoke! And as for refueling, what's it going to do - have trawlers and factory ships come alongside, to offload all the offal they've removed before freezing the edible parts of their catch?
I'm not sure Hurtigruten has thought through all that this entrails . . .
