Anew Climate and Avenir LNG have completed their first joint liquefied biomethane (bio-LNG) bunkering operation in Europe at the LNG terminal in the Port of Klaipėda, Lithuania.

During the operation, Anew supplied certified waste-based bio-LNG to an Avenir vessel at the KN Energies-operated terminal. The cargo was then transported to Sweden for use by vessels operated by ferry company Destination Gotland.

The companies said the operation marks Anew’s first bio-LNG bunkering project in Europe and follows earlier bio-LNG bunkering activity in North America, supporting the expansion of international bio-LNG supply chains.

Avenir used the 7,500-cbm Avenir Ascension for the operation. The vessel is part of Avenir’s fleet of five LNG bunker and supply vessels, with two more ships under construction. Operating across Northwest Europe, Avenir Ascension carries out more than 200 operations each year, supplying LNG and bio-LNG to marine and industrial customers, mainly in the Baltic region.

According to the companies, the bio-LNG delivered in Klaipėda comes from Anew’s biomethane portfolio and is intended to support near-term emissions reductions. They said the fuel is optimised for negative lifecycle carbon intensity, complies with FuelEU Maritime and RED III requirements, and can be used with existing LNG infrastructure without requiring changes to vessels or bunkering systems.

The partnership combines Anew’s capabilities in biomethane aggregation, certification and regulatory compliance with Avenir’s fleet, bunkering capacity and customer network.

With regulations such as FuelEU Maritime, RED III, the EU ETS and evolving International Maritime Organization (IMO) rules increasing pressure on shipowners to cut lifecycle emissions, the companies said certified bio-LNG offers a practical drop-in route to decarbonisation while allowing normal operations to continue.

John Cosmo Dwelle, Managing Director, Anew Climate Europe, remarked: “Greening shipping is not a future ambition – it is happening today. By combining our expanding renewable gas network with Avenir’s maritime infrastructure, we are delivering robust, fully certified bio-LNG supply chains that are practical, flexibly accessible, and aligned with regulatory requirements. We are proud to launch our first initiative with Avenir as we expand our bio-LNG offering globally.”

Jonathan Quinn, Managing Director, Avenir, said: “Bio-LNG plays a crucial role in reducing emissions from shipping today. This transaction with Anew strengthens our ability to deliver reliable, traceable bio-LNG solutions, directly supporting our customers as they reduce emissions and progress on their decarbonisation pathways.”

Henry Hammarström, senior energy and climate strategist and head of sales at Gotland Carbon Solutions, commented: ”We are happy to see bio-LNG delivered to our vessels through Anew Climate and Avenir. For 2026, we are increasing Destination Gotland’s use of bio-LNG in order to support FuelEU Maritime compliance of vessels that need support to comply with the greenhouse gas criteria of the regulations through pooling”.

In October 2025, Anew Climate completed its first bio-LNG loading at the Port of Long Beach in collaboration with Seaspan Energy, launching certified bio-LNG bunkering services for ships operating along the west coast of North America.
