Exploring CI combustion of ammonia and hydrogen in an ICE with a single-zone thermodynamic model incorporating reaction kinetics

This graduation thesis studies the CI combustion of ammonia and hydrogen in an ICE. It contains a review of the literature and a modeling study of the ignition and cylinder performance of the AmmoniaDrive test engine. AmmoniaDrive is a NWO-funded research project that aims to decarbonize shipping by introducing an ammonia-fuelled SOFC-ICE power...

An Ammonia-Fuelled Solid Oxide Fuel Cell - Internal Combustion Engine Hybrid System for Ships

Ammonia (NH3) may reduce CO2 emissions from the marine industry as it is carbon-free and more energy-dense than hydrogen or batteries. Pure ammonia exhibits poor combustion characteristics, so several researchers have already operated small-scale internal combustion engines (ICEs) with ammonia-hydrogen blends. However, nitrogen oxides NOx and...

An investigation of hydrogen-ammonia combustion inside internal combustion engines

Ammonia can become an attractive alternative fuel source on-board of ships, since it does not produce SOx and carbon related emissions (including CO2, CO and soot). However, pure ammonia combustion is too slow to drive an internal combustion engine (ICE), a promoter fuel such as hydrogen is needed to speed up the combustion process. Since the...
