Today, Rederiet Læsø has two older diesel ferries daily crossing a route from Frederikshavn to Vesterø Habor by 4-8 trips. This requires around 1,600 cubic meters of diesel oil annually, which emits around 5,000 tonnes of CO2. Replacing diesel to methanol as a carrier to hydrogen and diesel generators to the fuel cell technology will significantly reduce CO2 and particle emissions. And as a future goal, the ferries will run on green methanols. contributing to NetZero and setting Rederiet Læsø in favourable economic position to avoid taxations.

Rederiet Læsø plans to invest in a new ferry in 2024-2025, replacing the eldest one. While the simple answer would be to replace both ferries, ie Magrete also, considerations needs to be done in terms of its expected reminder lifetime and the environmental potential of rebuilding rather than wasting.

Supportive to the project, a consortium of partners closing the value chain collaborates to carry out pre-studies and outline scenarios to options for technologies, fuels and infrastructure and safety issues relevant to retrofitting the ferry to run on methanol.


  • Pre-studies and scenarios to outline options for technologies, fuels and infrastructure and safety issues in retrofitting the ferry to run on methanol.

  • Communications and PR.

Study trip to Stenaline Germanica

As part of the prestudy, delegates from the supply chain in consortium went to visit Stenaline in Gøteborg and to inspect Stenaline Germanica. In 2015, Stena Germanica became the world’s first RoPax vessel converted to run on both diesel and methanol. The delegates were given a guided tour onboard Stena Germanica and given great insights into the experiences of the process to Stenaline Germanica.

30 percent of the CO2 emissions that a ship emits during its lifetime comes from the construction of the ship. We have to look at the CO2 footprint throughout the life of the ship, and we are sure there is a greater CO2 saving potential in rebuilding than building new
