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.

In three green maritime corridor announcements this week:

• Chile’s Ministry of Energy and the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping will develop a network of transport corridors in and out of the country.
• The Global Maritime Forum will lead an Australian consortium seeking to establish ammonia-powered iron ore transport routes between Australia and southeast Asia.
• and the US State Department has outlined its official approach to green corridors, describing them as a “key means of spurring the early adoption of zero-emission fuels” like ammonia.
