Title

Hydrogen and ammonia combustion and emission control


Abstract

This talk is aiming to discuss and summarise the production and supply of hydrogen and ammonia then explore their combustion characteristics and required combustion technologies to support direct net zero emissions. As hydrogen can help internal combustion engines and industrial gas turbines to implement fast ignition and high temperature combustion, the difficulty for hydrogen storage and high NOx emissions generated by high combustion temperature needs necessary research outcome. Ammonia can be stored with liquid stage (for high energy density) easier than hydrogen, but it is difficult to get ignition and its low combustion temperature limits the combustion efficiency. Combining hydrogen and ammonia for dual fuel combustion can get a better solution if the fuel supply system can be developed well and the combustion control can be managed for ideal combustion phase. Characteristics of hydrogen and ammonia mixing preparation, combustion process and emissions will be important for the design and development of next generation net zero engines.
