content: Not much. Cruise line is planning to run a number of ships on liquefied biogas.IMHO the pollution at point of use is going to be pretty low if everything is working properly, but I wouldn't want to live downwind of the bioreactor that's basically rotting fish, or anywhere near where they dispose of the spent sludge or even be on-board if there's even a small gas leak from the fuel system, as the stench is likely to make you reacquainted with everything you've eaten in the last week.

content: The biogas reactor use mainly three sources: corn (whole plant), manure and residues from water treatment plants. They sometimes also add other plant material. Even old fish is usually to valuable and feed to chicken or fish.What is left over is usually not smelly, even if they start in the smelly side. So it's more the surprise when one sees them spreading a dark liquid to the fields and one hardly smells anything.They start to build cruse ships propelled with liquefied natural gas, which is chemical the same as the methane from bio-reactors.

content: I think I would vomit thinking about what is in the engine/fuel room of that ship. No thanks.vacation for people that work in a chicken processing plant? who would wanna be around that ?

content: If you've ever been to Norway you would notice they like the smell of dead decaying fish. They hang it up outside their houses.

content: In Norway can’t you get dead rotting fish in a can to eat? Surströmming. Like guns, cans of surströmming can not be taken on a plane.Not sure if you have ever been driving behind a car that uses biofuel from a restaurant like McDonalds. But the exhaust smells like french fries. Not quite as bad as surströmming, but not pleasant either.

content: Quote from: coppercone2 on November 24, 2018, 11:45:16 amThe fuel made out of organic waste, being dead fish or whatever else, won't necessarily smell much of anything if this is all processed properly, but that could be costly. "Biofuel" plants processing organic waste have odour control systems that are costly and themselves consume some energy...My questioning with all that is more about the net outcome (same problem than with most renewable energy sources to this day). I'm really not sure it would be favorable, so again it may seem either funny or a "nice try", but probably not very scalable either.

content: Fish emulsion is much liked by organic farmers because it powerfully stimulates compost-grown gardens to produce faster.

content: Have any calculations been made on how many tons of fish per km the ship will get?For a car to be powered by biofuel a is the calculation something l1 km per 4,000 sq meter of buoiofule crop?
