Wasaline to use only bio-LNG on Baltic Sea shipping route

Finnish shipping company Wasaline has signed agreements with Nordic energy player Gasum and Swedish ferry operator Stena Line to use only liquified biogas (bio-LNG) on its Baltic Sea route, aiming for a carbon-neutral shipping operation.

Wasaline signed a biogas contract with Gasum and a FuelEU Maritime pooling agreement with Stena Line, enabling the use of biofuels only in the daily operation of Aurora Botnia, a hybrid ferry that transports passengers and freight across the Baltic Sea between the port of Vaasa in Finland and the port of Umeå in Sweden.

Aurora Botnia can run on batteries, LNG, and bio-LNG, with an extension of the battery capacity of 10.4 MWh announced earlier this year. After the conversion with additional battery capacity in partnership with AYK Energy, Foreship, and Wärtsilä in January 2026, the vessel will have the biggest battery capacity on a RoPax, with a total of 12.6 MWh.

Wasaline’s agreements with Gasum and Stena Line are also expected to make the Vaasa – Umeå route the first international green shipping corridor in operation, following support from the DNV-led
