Dynamic modelling of ammonia crackers and hydrogen pem fuel cells for shipping applications
Dynamic modelling of ammonia crackers and hydrogen pem fuel cells for shipping applications
The pathway towards sustainable maritime propulsion is unclear. One concept is using ammonia as a fuel. This study investigated using an ammonia cracker (a device to convert ammonia to hydrogen) and a Proton Exchange Membrane fuel cell. This requires a hydrogen buffer tank and purification, each process has been dynamically modelled. Simulations show the power demand for different vessel types (cargo and survey) for several routes. This enabled analysis of ammonia demand and system requirements during: in port; manoeuvring; cruising; surveying. The same simulations ran for other potential setups to facilitate a fair comparison of the technical challenges, storage requirements, and support system requirements (e.g. batteries). Results showed that the total system plus fuel for this concept for a case study cargo voyage would weigh 150 tonnes and require 586 m3 of volume. For comparison, a liquid hydrogen system for the same voyage weighed 35 tonnes and required 222 m3 .

Abstract
The pathway towards sustainable maritime propulsion is unclear. One concept is using ammonia as a fuel. This study investigated using an ammonia cracker (a device to convert ammonia to hydrogen) and a Proton Exchange Membrane fuel cell. This requires a hydrogen buffer tank and purification, each process has been dynamically modelled. Simulations show the power demand for different vessel types (cargo and survey) for several routes. This enabled analysis of ammonia demand and system requirements during: in port; manoeuvring; cruising; surveying. The same simulations ran for other potential setups to facilitate a fair comparison of the technical challenges, storage requirements, and support system requirements (e.g. batteries). Results showed that the total system plus fuel for this concept for a case study cargo voyage would weigh 150 tonnes and require 586 m3 of volume. For comparison, a liquid hydrogen system for the same voyage weighed 35 tonnes and required 222 m3 .
