NH3 Clean Energy will collaborate with Woodside to progress the Angel CCS project offshore of the Pilbara in northwestern Australia. Meanwhile, NH3 will work with Oceania Marine Energy and Pilbara Ports to establish an ammonia bunkering service at the Port of Dampier by 2030, targeting iron ore transport between Australia and Asia.
We explore recent, full-scale, four-stroke engine testing results from IHI and Wärtsilä. Testing indicates N2O emissions can be almost fully eliminated with catalytic treatment, and significantly lower NOX emissions for engines running in ammonia mode, compared to running on diesel. While ammonia slip remains a key consideration due to the design of a four-stroke engine, catalytic treatment of the exhaust can eliminate even high concentrations, and release mitigation systems have already been designed and deployed to ensure safe operations.
Based on their analysis, UMAS and the University College of London conclude that scalable e-fuels have the highest potential to meet shipping’s new decarbonization targets, but that the next decade is critical to ensure supply chains are ready to supply these fuels. Ammonia-LNG dual-fuel vessels represent the lowest-risk, cheapest decarbonization option to the mid 2030s.
Trafigura has signed a contract for four medium-sized gas carriers, featuring WinGD dual fuel ammonia engines. The vessels will be built at HD Hyundai Mipo Dockyard in Ulsan, South Korea, and the first ship will be delivered in 2028.
ClassNK, DNV, Lloyd’s Register and the American Bureau of Shipping have all released new resources to support the implementation of marine ammonia fuel. We explore vessel operation guidelines and best-practice recommendations, seafarer training programs, and models for ammonia leak dispersion onboard vessels.
We explore recent, full-scale, dual-fuel engine testing results from leading maritime vendors such as MAN Energy Solutions and WinGD. Testing indicates negligible emissions of the potent GHG N2O (which can be fully eliminated with catalytic treatment), and significantly lower NOX emissions for engines running in ammonia mode, compared to running on fuel oil or diesel. Overall, compliance with IMO Tier II and III emission limits is well within reach for the first generation of ammonia-fueled maritime engines.
