Jason Stefanatos (pictured), global decarbonisation director at DNV, shares insights into the evolving regulatory and technical landscape surrounding ammonia’s potential as a marine fuel.

Ammonia’s primary appeal lies in its ability to provide carbon-free combustion, giving it a strong environmental advantage over traditional fossil fuels. “Ammonia is emerging as a possible fuel option, in part, due to its carbon-free combustion,” Stefanatos explains. Compared to hydrogen, it offers practical advantages in storage and transport—two major hurdles for large-scale maritime use.
