malteEr færger klimavenlige? Svarene er virkelig i øst og vest. Jeg har forsøgt at blive klogere. Min bedste forståelse af den klimavenlige færgetur kan koges ned til denne sætning: Den ideele færgetur tilbyder en smutvej, er beregnet til transport (ikke cruise), kører på vedvarende energi (eller i det mindste LNG), du er gående passager, og færgen kører relativt langsomt. Uddyber her: https://minus1.ghost.io/faergers-klimavenlighed #transport #ferry #klimarejser #climatetravel
Højt på min ønskeliste: En opdateret oversigt, gerne som kort, over færgeruterne i Europa hvor deres energikilde fremgår (diesel, el, LNG, hybrid etc). Findes det?

This is such an interesting topic! Thanks for bringing it up. I tried to look into it myself some years ago, and I also reached the same conclusions as you regarding speed and avoiding cruise lines.

If you wanna be a nerd about it, here are some of the formulas behind calculating fuel consumption. TL;DR: speed matters A LOT.
Here is a link about more nerdy bigship fuel consumption:

@malte Ferries 3/3:
What I think would be extremely useful would be to have public accessible data for each ships a) total fuel consumption pr year and, b) total miles sailed pr year. This would give a quite cualified mean figure to compare ferries. This data surely exists, but not for the public eye. I know the Danish state requires shipping companies to report these kind of data on a company level already.

@malte another very viable option I see is to make it easy and desirable for shipping companies to bring passengers (again).. Any cargoship can legally bring up to 12 passengers. Right now some of the main obstacles are insurance and visa bureaucracy. I think this could be solved. Not as romantic as green sailing vessels, I know, but until capitalism burns down, these ships will be going all over the place anyway, and you would just be hitching a ride..
@malte here is a density map of current shipping lanes globally and in the North Atlantic.
@kaalogkartofler Speaking of maps, do you know of a map of passenger ferries in Europe where their energy source is stated?
@malte unfortunately not :( And there is a lot of greenwash with hybrid vessels BTW. Like, it doesn't make your vessel much greener if you just install a big batterypack and then charge it by burning diesel fuel in your onboard generators:) If you connect to the powegrid in port it is a completely different story.
@kaalogkartofler LOL, do these exist? Battery propelled ferries that charge their batteries with an onboard diesel engine? That is some unnecessary electrical generation.
@malte yes that exists. It presumably make the ship more efficient, because the batteries can better handle the peaks in powedemand that occur. So it does save some fuel and some notable wear and tear on the generators. But that doesn't make it green.
(Also, I speak about shipping in general now, not sure about the ferries in particular).

@kaalogkartofler Let me know if you come across one of those maps. I would love to see it..
