UK-based LNG bunker supplier Avenir LNG bunkered a ferry operated by Destination Gotland with an undisclosed amount of bio-LNG using the mass balancing concept in the Swedish port of Visby.

The stem was delivered by Avenir LNG’s bunker vessel Avenir Aspiration. The operation marked the first bio-LNG delivery to a ferry operated by Destination Gotland.

“The bio-LNG that was delivered to Destination Gotland came from the Fluxys LNG terminal in Zeebrugge. It was produced on a mass-balancing basis, which is the standard way to do it for marine customers,” Avenir LNG’s commercial director of LNG bunkering Jan Schubert told ENGINE.

“Physical bio-LNG is too expensive and is not available in sufficient amounts,” Schubert argued.

Mass balancing is a method to track sustainable feedstocks in the supply chain, allowing for the blending of renewable and non-renewable materials while keeping an accurate tally of each. By quantifying the amount of sustainable feedstock used during production, distribution, blending, and bunkering, it ensures that the blended fuel’s claimed sustainability matches the actual amount of sustainable feedstock used.

In 2022, Avenir LNG inked a multi-year deal with Destination Gotland to supply LNG to the dual-fuel RoPax ferries MS Gotland and MS Visby.
