In the pursuit of environmentally friendly transportation, major players such as Toyota, in collaboration with China’s GAC Group, are exploring revolutionary alternatives to electric vehicles (EVs) – in particular, an engine powered by ammonia.

What is an ammonia engine?

The essence of an ammonia engine is its fuel: ammonia, a compound consisting of one nitrogen atom and three hydrogen atoms. At the same time, there are no carbon atoms, which ensures the absence of carbon dioxide emissions during combustion of the fuel. This feature allows us to consider ammonia engines as an environmentally friendly solution to combat environmental pollution.

Ways of utilizing ammonia energy.

Decomposition approach: Startups such as Amogy have demonstrated the splitting of ammonia into hydrogen and nitrogen. The former powers a fuel cell, generating electricity.

Combination approach: MAN Energy Solutions (MAN ES) blends ammonia with fuels such as diesel or gas to promote sustainable combustion.

Pure ammonia approach: In this case, ammonia acts as the primary fuel and advanced combustion technologies are used.

Why ammonia engines are promising.

Ammonia has a high energy density, which is essential for efficient energy storage and transportation. This makes it suitable for use in critical industries such as transportation and power generation.

In addition, ammonia’s main components, hydrogen and nitrogen, are abundant, emphasizing the engine’s potential environmental friendliness.

Toyota is taking the lead.

In collaboration with GAC, Toyota has unveiled a prototype engine powered by liquid ammonia. This 2.0-liter engine with 161 hp can reduce carbon dioxide emissions by 90%.

However, it has not been without its challenges along the way. Issues such as controlling combustion chamber pressure and handling nitrogen emissions required innovative solutions.

Challenges and future prospects.

Despite its prospects, ammonia is not without its difficulties:

Difficulty of ignition: Compared to fossil fuels, ammonia requires higher ignition energies.

Safety concerns: Its pungent odor and toxicity require careful handling.

For wider distribution, automakers need to refine the technology and bring it into compliance with regulatory requirements. Nevertheless, with major stakeholders like Toyota, a future for clean ammonia fuel seems likely.

China’s role and previous endeavors.

China, home to the world’s largest electric vehicle market, has expressed interest in banning internal combustion engines. The emergence of alternative fuels such as ammonia could reshape the market.

Toyota’s position in China and its commitment to meeting the diverse needs of consumers underscores its integrated approach. Research on ammonia engines suggests the possibility of global adoption in the future.

It should be noted that work on ammonia engines has been done before. The AmVeh engine developed by the Korea Energy Research Institute combines 70% ammonia with 30% gasoline to reduce carbon dioxide emissions by 70%.

Conclusion.

As sustainable transportation advances, collaborative efforts to harness the potential of ammonia mark a turning point. The convergence of technology, industry, and the environment points to a promising future despite the challenges that remain.
