The Effects of Ammonia Fuel on the Environment
Switching to ammonia fuel can significantly lower carbon emissions in multiple industries. However, there are a few environmental factors to take into account:
Reduced Greenhouse Gases: Ammonia combustion emits only nitrogen and water, offering a lower-emission option for many sectors.
Nitrogen Oxides (NOx) Production: Combustion of ammonia can lead to NOx emissions, which are pollutants. Advanced technologies are needed to control these emissions effectively.
