Ammonia energy storage and combustion

Why is ammonia an attractive energy storage system?

Ammonia offers an attractive energy storage system due to its well-established infrastructure. Ammonia showed great promise as a viable hydrogen fuel carrier. Energy can be stored in the chemical bonds of ammonia through the endothermic ammonia synthesis reaction. Ammonia can be used as a fuel in fuel cells and internal combustion engines.

How can ammonia be used as an energy source?

The most effective way to use ammonia as an energy source is through its combustion. This process overcomes challenges such as low flammable characteristics and fuel NOx emission, thanks to the knowledge of the dynamics and chemistry of combustion.

What are the advantages and disadvantages of ammonia?

The advantages of using ammonia as a fuel include its availability, amenability to storage and transport, and its utility for various energy and industrial applications. It is also a hydrogen carrier. The combustion of ammonia is the most effective way to use it as an energy source, making it a key technology.

What are some challenges in ammonia combustion?

The combustion of ammonia, which is the most effective way to use ammonia as an energy source, is a key technology. Challenges such as low flammable characteristics and fuel NOx emission can be overcome by the knowledge of the dynamics and chemistry of combustion.

What challenges does using ammonia as a fuel face?

Ammonia is emerging as a viable alternative to fossil fuels in combustion systems, aiding in the reduction of carbon emissions. However, its use faces challenges, including NOx emissions and low flame speed. Innovative approaches and technologies have significantly advanced the development and implementation of ammonia as a zero-carbon fuel.

What promotes ammonia combustion?

While hydrogen promotes the ammonia combustion because of its higher burning velocity and low ignition energy, the side-effect of high NOx emissions may arise due to its high flame temperature and rich radical pool of O/H.
