Eltronic FuelTech is proud to be among the key contributors to a groundbreaking concept design for a 3,500 TEU ammonia-fueled container vessel, recently unveiled by the Mærsk McKinney Møller Center for Zero Carbon Shipping (MMMCZCS)

Eltronic FuelTech is thrilled to announce its involvement in an extensive project aimed at accelerating maritime decarbonization: the development of a concept design for a 3,500 TEU ammonia-fueled container feeder vessel, led by the Mærsk McKinney Møller Center for Zero Carbon Shipping (MMMCZCS).

This innovative vessel concept was developed through close cross-industry collaboration with leading industry partners including Maersk, Everllence, Deltamarin, ABS, and LR. It has recently received Approval in Principle (AiP) from top classification societies, affirming ammonia’s technical feasibility and safety viability as a next-generation marine fuel – a significant milestone for the project.

Eltronic FuelTech has played a central role in the concept development by designing the complete onboard ammonia fuel system – from tank to engine – including bunkering, tank conditioning, venting, double-wall ventilation, and fuel supply and return systems, as well as fuel valve train (FVT) systems for both main and auxiliary engines. Leveraging extensive expertise in advanced fuel handling technology, Eltronic FuelTech has led the process design with a strong emphasis on operational integrity and the highest safety standards.

–  We are proud to contribute to a vessel concept that not only advances ammonia propulsion but also supports regulatory development and builds confidence across the maritime sector,
says Michael Asger Wulff, CCO of Eltronic FuelTech.

This project has significantly deepened Eltronic FuelTech’s understanding of the installations required for ammonia-powered vessels, enabling us to develop solutions that are more seamless and easier to integrate. It has also fostered valuable and practical discussions on safety, solutions, and requirements with leading ship designers, operators, and certification authorities – ensuring that our future innovations are rooted in real-world needs and aligned with industry standards.

Beyond its technical innovations, the concept design provides a scalable blueprint for early ammonia adoption in commercial shipping – a powerful example of how cross-industry collaboration can move global shipping toward a zero-carbon future.
