What are the opportunities and challenges for ammonia as a marine fuel?

The shipping sector is searching for practical, scalable pathways to decarbonisation, and ammonia continues to attract significant attention as a potential marine fuel. But what does the evidence actually show? What technical, operational, safety and commercial challenges remain? And how close are we to real-world deployment?

Join the NEXT GEN Ammonia Workshop, suported by MariNH₃, for an exclusive opportunity to hear directly from leading researchers, industry experts, regulators and maritime stakeholders who are shaping the future of ammonia-powered shipping.

Why attend?

Over the past four years, MariNH₃ has brought together expert researchers from five leading UK engineering universities and 25 industry partners to tackle one of the biggest questions facing the maritime sector:

Can ammonia be used safely, efficiently and commercially as a fuel for marine engines?

For the first time, major findings, lessons learned and engineering breakthroughs from this collaborative programme will be shared with a wider industry audience. Attendees will gain access to candid discussions on what is working, where challenges remain, and what this means for the future of maritime decarbonisation.

Unlike traditional conferences, NEXT GEN workshops are designed to encourage open, honest discussion and meaningful engagement between experts and participants. NEXT GEN House Rules: No lawyers, insurers or journalists. This creates an environment for frank discussion, practical insights and lively Q&A sessions where both the benefits and limitations of ammonia as a marine fuel can be explored openly.
