Japan trusts ammonia engines, not hydrogen!

The automotive industry is rapidly changing, with environmental consciousness growing every day. While electric vehicles (EVs) are widely discussed, a new alternative developed by Toyota and China’s Guangzhou Automobile Group (GAC) is stirring up questions about the future of motor technology. Could ammonia engines replace hydrogen engines?

New fuel and engine technology from Japan: Ammonia instead of hydrogen

Toyota and GAC have developed an environmentally friendly engine that can replace fossil fuel engines. This engine runs on ammonia, emitting very little carbon dioxide when burned, making it almost harmless to the environment. The 2.0-liter electronically controlled four-cylinder engine produces 161 horsepower and is 90% less harmful than conventional gasoline engines.

Ammonia, composed of one nitrogen atom and three hydrogen atoms (NH3), is an excellent compound to replace carbon. It is already widely used in agriculture and manufacturing, meaning the production infrastructure is largely in place. However, using ammonia as a fuel for personal vehicles presents some challenges.

It worked on the first try! Students create the first hydrogen engine

University of Bath students developed the world's first internal combustion hydrogen engine produced by undergraduate students.

Ammonia synthesis is an energy-intensive process, and its environmental impact can only be reduced using clean energy sources like wind or solar power. Additionally, ammonia is a toxic chemical with combustion potential and is highly corrosive, making long-term transportation or storage unsafe.

The Japanese believe that if these challenges can be overcome, ammonia could be the fuel of the future. Toyota, with its past successes in hybrid and hydrogen fuel cell technologies, shows that it is still exploring new solutions beyond battery-powered electric vehicles.

Despite the significant market acceptance of electric vehicles, the concept of an ammonia engine suggests that internal combustion engines could still be relevant in a low-carbon environment. However, without addressing the issues of ammonia production, transportation, and the necessary infrastructure, ammonia is unlikely to become a common fuel for passenger cars in the short term.
