Ammonia is not only a hydrogen energy carrier but also a carbon-free fuel. It has great potential to reduce greenhouse gas emission from energy conversion systems when it is used as a fuel for direct combustion. However, some challenges related to combustion characteristics of ammonia exist for the utilization in combustion apparatus such as gas turbine, automobile engine, marine engine, industrial furnaces, etc. In this article, fundamental characteristics of ammonia combustion and the mechanism of those are explained based on combustion science, and then some methods to overcome the challenges are introduced.
