Ammonia as a fuel for shipping - Frequently asked Questions

What are the typical safety risks and additional safety requirements for Ammonia?

Ammonia is flammable, can be explosive, but it has a low reactivity. It is highly toxic and can present material compatibility issues. We have addressed these within our rules and regulations for the consumption of ammonia as fuel.

What are the safety implications of ammonia’s toxicity?

Burning toxic fuel on ships risks exposing humans and marine life to the toxin. The
exposure depends on both concentration (parts per million) and duration.
Regulations such as dosage limits from governments and agencies aim to manage this risk. For ship crews, both the level and length of exposure matter to assess any consequences and understanding these factors is crucial for safety in the marine industry.

Are there any ammonia-fueled marine engines?

Currently, there are no certified ammonia-fueled engines for ships. While manufacturers like MAN, WIN GD, and Wartsila are simulating, testing single cylinders, and building facilities for full-scale engine validation, crucial data on environmental impact (N2O and ammonia slippage) and operational safety (toxicity during maintenance and inspection) remain missing. We actively collaborate with these manufacturers to unlock the potential of ammonia while ensuring thorough environmental and safety evaluations before approving any engines for marine use.
