LEAD: Ammonia-Fueled Vessels
With the commercialization of Ammonia-fueled engines in 2024 and 2025, the adoption of ammonia as maritime fuel is taking off. The number of vessels that will operate on ammonia provide clear signals to both ammonia producers and infrastructure providers that ammonia bunkering capacity will be required.
Ammonia bunkering has been demonstrated in various ports. Ammonia bunkering as a service is shaping up, with partnerships emerging between ammonia producers, ammonia traders, ammonia terminal operators and bunkering service companies.
Key insights
- As of March 2026, 140 ammonia-fueled vessels and 313 ammonia-ready vessels have been ordered and announced, or are already operational. Small-scale Supply vessels (Tugboats) are the first operational references for ammonia-fueled vessels, entering the water in 2023, 2024 and 2026.
- Out of the 53 ordered ammonia-fueled vessels, 23 vessels are ammonia carriers; 18 vessels are bulk carriers. The first of these vessels are expected to hit the waters in 2026 and 2027.
- The first ammonia-ready vessel entered the waters in early 2022. As of March 2026, 89 ammonia-ready vessels are operational.
