Ammonia Value Chain the amount of oxygen in the intake air, and the fear is that this will have a very negative impact on the performance of ammonia combustion, but this is still to be investigated.

In addition to main engines and gensets operating on ammonia, designs are also emerging for auxiliary engines required to complete the transition to vessels run- ning on ammonia. Boilermakers are pre- paring dual fuel boilers for use with am- monia as fuel to be able to generate steam and heat from burning ammonia.

Working with ammonia onboard on a day-to-day basis requires a solu- tion to collect ammonia vapor in a safe manner. Different solutions for vapor handling are under development from

In this solution, ammonia vapor is stored in dedicated tanks as a water-ammonia solution. However, this approach would require dedicated infrastructure at the port to receive and store it.
