Ammonia is also emerging as a potential alternative, zero carbon fuel for shipping. By early 2024, the first ammonia-ready ships engines will be ready for installation on newbuilds. The first models will be dual-fuel, able to run on traditional marine gas oil as well.
The Clean Marine Fuels Working Group is also looking into work on developing safety tools for Ammonia as a marine fuel. It has signed a memorandum of understanding with the Society of Gas as a Marine Fuel.
In the meantime, the Port of Amsterdam, which is a member of the Clean Marine Fuels Working Group, has published an external safety study with DNV on bunkering of alternative marine fuel for seagoing vessels and on spatial considerations when looking at installing bunkering infrastructure at ports for fuels such as ammonia.
