Port of Singapore trials world’s first use of ammonia as marine fuel in a DF ammonia-powered vessel


The Maritime and Port Authority of Singapore (MPA) reports that the world’s first use of ammonia, in combination with diesel in the combustion process, as a marine fuel onboard the Singapore-flagged ammonia-powered vessel, the Fortescue Green Pioneer, was successfully carried out in the Port of Singapore earlier this month.

The vessel was loaded with liquid ammonia from the existing ammonia facility at Vopak Banyan Terminal on Jurong Island for the fuel trial which took place earlier this month.

In completing the fuel trial, the Fortescue Green Pioneer has also received flag approval from the Singapore Registry of Ships (SRS) and the ‘Gas Fuelled Ammonia’ notation by classification society DNV to use ammonia, in combination with diesel, as a marine fuel.

Mr Teo Eng Dih, Chief Executive, MPA, said: “The safe conduct of this fuel trial supports the holistic assessment of the use of ammonia as a marine fuel, and the development of standards and safety procedures. This will inform the crew training, emergency and bunkering procedures which MPA, agencies and the tripartite community are developing in support of making available safe and cost-efficient solutions as MaritimeSG and the international shipping community undergo the energy transition.”

Dr Andrew Forrest AO, Chairman of Fortescue, said: “Australia and Singapore are nations for whom the seas are our lifeblood and Fortescue has seen firsthand the willingness of Singapore to lead the world in taking brave, innovative action to build green ammonia shipping.

“My message to the Singaporean Government is only green is green. Anything else is made from fossil fuels. The Fortescue Green Pioneer is proof that safe, technical solutions for ammonia power engines exist.

“But as I did at COP 28 in Dubai, I am once again calling on the world’s ports to get on with setting fair, safe and stringent fuel standards for green ammonia and not shy away from their responsibilities simply because of a lack of character. We must push to see global emitters paying fair carbon prices for heavy fuels used in traditional shipping. These prices must provide clear investment signals to drive green investment.”

Cristina Saenz de Santa Maria, Regional Manager South East Asia, Pacific & India, Maritime, DNV, said: “We are proud to be partnering with Fortescue and MPA on this groundbreaking project, which sets a new benchmark for the use of ammonia as a marine fuel and reinforces Singapore’s leadership in alternative fuel bunkering.

“Working closely with both teams over the last two years, we have undertaken a rigorous technology qualification process to ensure the safety and performance of the ammonia fuel systems and engine retrofit. The successful culmination of this project reflects Fortescue and MPA’s commitment to drive innovation and cooperation in the industry, a vision that we share at DNV as we help our customers achieve their decarbonisation objectives.”
