In recent months, TT-Line, EnviTec Biogas, Viking Line, Gasum, Wasaline, Destination Gotland, Stena Line and Avenir LNG have agreed bioLNG fuel supply deals for ferries operating in north Europe.
Baltic ferry operator TT-Line has agreed a bioLNG fuel supply contract after a trial bunkering of 40 tonnes of renewable gas on ropax ferry Peter Pan in Travemünde, Germany. The deal followed a test delivery EnviTec Biogas carried out for TT-Line earlier in 2025.
EnviTec Energy managing director Markus Pille said, “We are delighted to be able to supply TT-Line’s ropax ferries, a combination of passenger and vehicle ships, with our renewable fuel bioLNG.”
EnviTec said its bioLNG, produced from organic biomass waste including slurry, dried poultry manure, food waste or agricultural residues, can cut emissions by up to 100% compared with marine diesel.
TT-Line chief financial officer Torben Nikolay said Peter Pan and sister ship Nils Holgersson, described by the company as the largest LNG-powered ropax ferries in the world, were intended to do more than fulfil regulatory requirements.
“These ferries represent far more to us than merely meeting legal requirements; we are preparing ourselves and our fleet as well as possible for a sustainable future,” Mr Nikolay said.
He added, “We have already carried out extensive bioLNG bunkerings by bunker barge this year and are now pleased to have found, in EnviTec Biogas, a German partner for particularly flexible bunkering by truck.”
Other north European ferry owners have also entered into bioLNG arrangements.
Sweden-headquartered Viking Line has started to run ropax vessels Viking Glory and Viking Grace on bioLNG supplied through Gasum’s FuelEU Maritime pooling service, and plans to increase purchases of liquefied biomethane.
Viking Line chief executive Jan Hanses said, “For us at Viking Line, taking every possible step towards more sustainable maritime transport is a top priority.”
Finnish operator Wasaline has signed a biogas contract with Gasum together with a FuelEU Maritime pooling agreement with Stena Line that will see hybrid ferry Aurora Botnia operate solely on bioLNG on the Vaasa–Umeå route in the Baltic Sea.
Wasaline managing director Peter Ståhlberg said, “With this unique collaboration with Stena Line and Gasum, Wasaline can achieve carbon neutrality now as a forerunner for the industry.”
In Sweden, Destination Gotland has received an inaugural delivery of ISCC-certified bioLNG supplied by Avenir LNG under a multi-year bunkering agreement for dual-fuel ropax ferries.
Avenir said the bioLNG was produced in Europe and loaded at the Zeebrugge terminal before delivery by bunker vessel Avenir Aspiration to the Port of Visby, where Destination Gotland’s ferries operate.
