Maersk, Svitzer to develop carbon-neutral methanol fuel cell tug

Svitzer, A.P. Moller - Maersk’s towage operator, has signed an agreement with Robert Allan Ltd, leading naval architect company, to design the first fuel cell tug for harbor operations running on green methanol.

The project builds on close cooperation between Svitzer and Maersk with the aim to explore the combination of methanol fuel cells, batteries, storage/handling systems, electric drives and propulsion units as a carbon-neutral alternative to the conventional fossil-fueled propulsion train.

Fuel cells will be applicable as main propulsion power for tugs earlier than for larger vessels and further, the time to build a tug is significantly less than for a container vessel. Svitzer will obtain valuable knowledge and operational experience handling fuel cells as an alternative to diesel or pure electric power. We consider this project a significant step in Svitzer’s ambition to lead the decarbonization of towage and an important contribution to the joint efforts to develop solutions with a positive impact on the environment.

—Ingrid Uppelschoten Snelderwaard, Global COO, Svitzer

Svitzer and Maersk are working closely together to determine technologies that support the overall Maersk decarbonization efforts. The objective is to extract and apply knowledge and operational experience of methanol feasibility from the near shore small-scale tug onto larger ocean-going container vessels.

Fuel cell technology could be a disruptor in the maritime technology space, promising high efficiencies and eliminating the need for substantial amounts of pilot ignition fuels while removing harmful emissions. Thus, we have been monitoring the technology for the last few years, and with the accelerating developments in the ‘Power-to-X’ arena, it has become evident that we should step up our engagement in fuel cells, especially in combination with Green Methanol.

—Ole Graa Jakobsen, Maersk Head of Fleet Technology

The 80 tons bollard pull newbuild tug with escort notation will come with a hybrid electrical propulsion system solution where fuel cells can be dimensioned to deliver a specific amount of sustained bollard pull using fuel cells alone, adding additional power from the batteries during the short but often frequent peaks that characterizes towage.

The fuel cells can be used to charge the batteries when the tug is mobilizing and when the tug is berthed, minimizing the need for expensive shore side charging facilities. The combination of fuels cells and batteries will deliver a self-sustained tug with longer endurance and with less operational constraints than a pure battery powered vessel.

The fuel cell tug will function as a pilot design for future Svitzer newbuilds and is planned to be put into operation within the Svitzer Europe region by Q1 2024.

If you did not notice that is a very aggressive schedule. Can they do it? Maybe.
Robert Allan Ltd, the naval architect has already designed and built both a diesel hybrid bollard tug, the TundRA 3600-H (Hybrid) tug VILJA (here are the specs: and the ESS specs: and a Methanol Fueled Crew Transfer Vessel (
Cannot find any reference to the Methanol Fuel Cell. Though best guess would be the Blue World Technologies HTPEM that is being constructed for testing at the Alfa Laval Test & Training Centre in Aalborg, Denmark ( The fuel cell setup will have a power of 200 kW, and the fully developed, modular design should scale up to 5 MW. Maersk Drilling is part of this project.
