Energy company Gasum and shipping operator Wallenius Sol have signed a cooperation agreement under which Wallenius Sol’s dual-fuel vessels, Baltic Enabler and Botnia Enabler, join Gasum’s FuelEU Maritime pool as compliance credit generator vessels. Starting in October 2025, these Enabler-class multi-fuel ConRo ships transitioned from liquefied natural gas (LNG) to liquefied biogas (bio-LNG) as part of the partnership.

Pooling through this service enables shipowners to achieve regulatory compliance and avoid financial penalties for carbon intensity shortfalls, offering a practical and cost-effective solution for maritime operators.

“Pooling is a brilliant and easy opportunity for all maritime actors to join forces in lowering emissions from the industry together,” said Jacob Granqvist, Vice President, Maritime, Gasum.

Under the arrangement, Wallenius Sol's vessels will generate a compliance surplus for other ships by running on bio-LNG. This will help pool participants meet EU carbon intensity requirements that came into effect this year.

The FuelEU Maritime regulation requires owners of vessels calling at EU ports to reduce the carbon intensity of fuel used by 2% in 2025. Companies that fail to meet this requirement face penalties.

Wallenius Sol operates scheduled services between ports in northern Finland and Sweden, Germany, the Benelux region, and the United Kingdom. The company's vessels handle trailers, containers, and project cargo for industries including paper and steel.

Jacob Granqvist, Vice President, Maritime at Gasum, said: "We are very excited that Wallenius Sol has decided to join our FuelEU Maritime pool, as this collaboration enables us to open even more regulation surplus to shipowners at this definitive stage. The window for securing compliance for 2025 is closing rapidly, and the available capacity may run out before the year end."

Rebecca Tagaeus, Chief Sustainability Officer at Wallenius Sol, said: "We aim to be the natural partner for sustainable sea logistics in the Gulf of Bothnia and across the European continent. Together with Gasum, we are scaling the use of renewable gases at sea."

Gasum takes responsibility for managing the pool. It provides bio-LNG to designated compliance generator vessels. DNV ensures the pool remains in balance at the end of the year.

Bio-LNG is claimed to have life-cycle emissions that are on average 90% lower than traditional fossil fuels such as marine gas oil. Gasum says it is working to increase the availability of renewable gas to help customers navigate the energy transition.

The partnership allows Wallenius Sol's customers to access lower-emission transport for their goods through the FuelEU Maritime cooperation with Gasum.

Tagaeus added that switching to bio-LNG for the company's Enabler-class vessels demonstrates that Wallenius Sol's sustainability roadmap is delivering results while supporting customer climate goals and accelerating the green transition across the Nordic region.
