Ammonia-powered vessels could be deployed on the iron ore trade routes between West Australia and East Asia from 2028, a new consortium study suggests. More than 20 vessels could be deployed on these routes by 2030, and over 360 by 2050. While ammonia fuel supply from Australia is unlikely to be a concern, validating the safety case for ammonia fuel, policy support to close the cost gap & industry-wide collaboration must all be established in time for deployment.

Since the Clydebank Declaration was signed last December, the prospect of ammonia-fueled, green maritime corridors has been steadily rising. The Global Maritime Forum has just released a valuable discussion paper on potential definitions and approaches for green corridors. Recent announcements in Europe, Singapore, Australia and the Nordic countries demonstrate growing momentum. For maritime stakeholders to capture early learnings and best manage the complex task of alternative maritime fuel scale-up, the opportune time is right now.
