World’s First Ammonia-Powered Vessel Conducts Successful Trial In Singapore


  • Fortescue, in collaboration with the Maritime and Port Authority of Singapore (MPA) and other partners, has achieved a significant milestone by conducting the world’s first use of ammonia as a marine fuel in a dual-fuelled vessel, the Fortescue Green Pioneer, at the Port of Singapore.
  • This trial marks a crucial step towards the adoption of alternative fuels in the maritime industry and underscores Singapore’s commitment to innovation and sustainability in shipping.

Ammonia, widely used in agriculture and industry, has emerged as a promising marine fuel capable of supporting the energy transition. As a carrier for hydrogen, ammonia can be produced sustainably and transported to power ships, contributing to decarbonization efforts in the shipping sector. The successful trial on the Fortescue Green Pioneer demonstrates the feasibility of using ammonia as a marine fuel and paves the way for future adoption.

Conversion of the Fortescue Green Pioneer

The journey towards ammonia-powered shipping began in 2022 when Fortescue converted a four-stroke engine to run on ammonia and diesel at its testing facility in Perth, Australia. Subsequent conversion work on the Fortescue Green Pioneer, including the installation of gas fuel delivery systems and safety infrastructure, enabled the vessel to operate on ammonia-diesel blends. The vessel, showcased at international events, highlights the potential of ammonia as a clean and viable marine fuel.

Safety and Regulatory Considerations

Extensive safety measures and training sessions were conducted in preparation for the fuel trial, ensuring the safe handling and operation of ammonia onboard the Fortescue Green Pioneer. Collaboration between industry stakeholders, research institutes, and regulatory bodies facilitated the development of safety protocols and incident response plans. The successful completion of the trial underscores Singapore’s commitment to fostering a conducive regulatory environment for maritime innovation and sustainability.

The world’s first use of ammonia as a marine fuel in a dual-fuelled vessel represents a significant achievement for the maritime industry and reinforces Singapore’s position as a leader in alternative fuel bunkering. As the global shipping sector transitions towards cleaner fuels, initiatives like this trial demonstrate the potential of ammonia to contribute to a greener and more sustainable future for maritime transportation.
