The future of mobility could be green ammonia

Sustainable mobility isn’t just about electric vehicles and hydrogen fuel cells. Green ammonia can also be a solution.

Ammonia is an extremely hazardous chemical that is mostly utilized as fertilizer, although manufacturers are becoming interested in it because of its flammable properties.

Although it has a lower energy density than gasoline (about half), it does not emit carbon, hydrocarbons, or CO₂ when it is burned.

The combustion engines that Toyota and GAC are producing are ready to burn ammonia. Although it isn’t the first engine designed to run on ammonia, it is the first that can be fitted into a passenger car. The 2.0-liter, four-cylinder engine developed by the Chinese manufacturers produces 161 hp and emits 90% less carbon than unleaded gasoline.

Green Ammonia

What is green ammonia

The advantages of using ammonia lie in the relative ease with which it can be produced, while also making it possible to maintain fuel distribution infrastructures. The traditional method of producing ammonia is considered energy-intensive, but recent developments have led to the small-scale production of green ammonia, which uses renewable energy sources for carbon-free production.

Ammonia presents additional difficulties in its utilization, including toxicity, storage, and applications outside of fuels. About 70% of the world’s annual ammonia production is used in agriculture as a fertilizer. In addition, it is utilized in the production of polymers, textiles, explosives, and herbicides as well as a refrigerant gas. Additionally, green ammonia may present more choices in the move toward net-zero carbon dioxide emissions, particularly as a viable hydrogen energy source.

The race to net zero

A new report called The Breakthrough Effect: How to trigger a cascade of tipping points to accelerate the net zero transition states that three “super-leverage points” could catalyse decarbonisation in sectors covering 70% of global greenhouse gas emissions. These points include mandates for the sale of electric vehicles, public procurement of plant-based proteins and mandates for green ammonia to be used in the manufacture of agricultural fertilisers.

These could lead to cheaper batteries to help solar and wind power scale-up in the electricity sector and cheaper hydrogen for the decarbonisation of shipping and steel production.

Mandates that require the use of green ammonia to make fertilisers could boost the hydrogen economy, according the report. Also, replacing fossil fuels in fertiliser production, would reduce the costs of green ammonia and green hydrogen, enabling their use as fuels in shipping and steel production as well as for energy storage.

UH2 projects

Our work with green ammonia

UH2 works with green ammonia as an alternative to fossil fuels, providing the same functionality on a large scale. A comprehensive and sustained shift to renewable energy depends on these green power options. UH2 has been working on alternative and innovative energy carriers and storage solutions for a number of years.
