MAGPIE project demonstrates that safe ammonia bunkering in ports is possible in International Shipping News , Shipping: Emission Possible 23/05/2026 A new demonstration project in the Port of Rotterdam shows that ship-to-ship ammonia bunkering can be carried out safely within an active port environment. The demonstration is part of the EU-funded MAGPIE project, and the report is now available, providing concrete learnings that industry can use to guide future ammonia bunkering and accelerate global port permitting. The shipping sector must transition away from fossil fuels to meet climate targets. Ammonia is considered a promising alternative fuel, but its specific hazards pose significant safety, operational, and regulatory challenges. Without competent operators, fit-for-purpose equipment and robust safety and regulatory frameworks, ammonia bunkering cannot take place safely in ports. Within the MAGPIE project, a full-scale simulation of a ship-to-ship ammonia bunkering operation was conducted in the Port of Rotterdam on 12 April 2025. The demonstration showed that ammonia bunkering within port limits is operationally feasible when carefully planned and executed within a robust safety and regulatory framework. The learnings from the demonstration have now been consolidated by the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping and project partners in a comprehensive ammonia bunkering demonstration report. This publication provides the industry with practical lessons and a validated port safety framework and tools that other ports can use as a blueprint for ammonia bunkering. A key outcome of the project is the validation of the Port of Rotterdam’s port safety framework for ammonia as a fuel, as well as the International Association of Ports and Harbours’ (IAPH) Port Readiness Tool. The results demonstrate that these frameworks are fit-for-purpose instruments for ports considering the introduction of new alternative fuels. The project delivers practical lear
