What You'll Learn
Ammonia is flammable at 15-28% volume concentration
Ammonia is a highly toxic and corrosive substance that can be dangerous to humans and the environment. It is also flammable under certain conditions, with a flammability range of 15-28% volume concentration. This means that if ammonia is added to someone's fuel tank, it could potentially ignite and cause an explosion. The effects of ammonia on an engine can be detrimental, even in the short term.
Ammonia has a high reactivity, and it is flammable when mixed with air or vapour. This can lead to corrosion in the engine, especially if metals such as alloys, brass, zinc, or copper are present. Even if the engine is adjusted or upgraded to run on ammonia, there is no guarantee that it will operate smoothly.
The difficulty in igniting ammonia means that it is often used in conjunction with a "pilot fuel", such as diesel, which can complicate engine operations. Additionally, ammonia does not have a flashpoint, and its explosion hazards should not be underestimated. The vapour concentration of ammonia solutions is determined by the saturated vapour pressure at a given temperature, and as the temperature increases, the concentration of flammable vapours in the air also increases.
Ammonia has been proposed as a potential alternative fuel for power generation, particularly in the shipping industry, due to its low GHG emissions when burned. However, the cost of producing ammonia, especially green ammonia, is currently much higher than that of fossil fuels.
In conclusion, while ammonia may have potential as a future fuel, its flammability, toxicity, and corrosiveness make it a risky option for current engine technology. Further studies and engineering solutions are needed to mitigate these risks and ensure safe usage.

It is highly reactive, toxic, and corrosive
Ammonia is a highly reactive, toxic, and corrosive substance. Its high reactivity means that it can be difficult to ignite in a typical engine, which may cause stalling and shutdowns. However, it is still flammable and can burn like a typical fuel. If mixed with vapor or air, it can lead to corrosion in your engine, especially if it comes into contact with metals such as alloy, brass, zinc, or copper.
Ammonia is also highly toxic if inhaled. Exposure to small amounts of anhydrous ammonia can lead to permanent loss of lung function. It can also cause pulmonary edema, turning fatty tissues, including cell membranes, into soap and causing dehydration in proteins. Even in small amounts, ammonia is a potent environmental toxicant, killing 50% of certain aquatic organisms at just 0.5 milligrams per litre.
As a result of its high reactivity and toxicity, ammonia is not an ideal alternative fuel. While it may be a promising candidate for future power generation, adjustments to engines are necessary to use it as a fuel, and it may still cause corrosion and difficulty in running the engine.
In summary, ammonia is a highly reactive, toxic, and corrosive substance that can cause severe damage to both human health and engines. While it may hold potential as a future fuel, its drawbacks mean that it is not a viable solution at present.

It can cause engine shutdowns and stalling
Adding ammonia to someone's fuel tank can have detrimental effects on the engine, potentially leading to stalling and even complete shutdowns. While ammonia can burn like a typical fuel, it is challenging to ignite and combust in a standard engine. This difficulty in combustion can cause the engine to exhibit symptoms of distress and malfunction, ultimately resulting in stalling.
Ammonia is highly reactive and toxic, and when mixed with vapour or air, it can lead to corrosion in the engine, particularly if it comes into contact with certain metals. Metals such as alloy, brass, zinc, or copper are susceptible to corrosion caused by ammonia. This corrosion can gradually damage the engine and the tank, impacting its performance and longevity.
The high reactivity of ammonia also poses a significant safety concern. When exposed to high temperatures, ammonia can explode, leading to dangerous and unpredictable outcomes. This flammability characteristic of ammonia further underscores the potential for engine shutdowns and stalling.
Furthermore, ammonia's toxic nature poses health risks to anyone inhaling its vapours. The toxic effects of ammonia vapour can have short-term and long-term consequences on individuals exposed to it. Therefore, it is crucial to avoid using ammonia as a continuous fuel source in vehicles to prevent potential health hazards.
In summary, adding ammonia to a fuel tank can lead to engine stalling and shutdowns due to its challenging combustion properties, high reactivity, corrosive nature, flammability, and toxic vapours. While ammonia may burn like fuel, its unique characteristics can disrupt the engine's performance and even damage its components. Adjustments to the engine may be necessary to accommodate ammonia as a fuel, but even then, smooth operation cannot be guaranteed.

It is difficult to ignite, so a pilot fuel is often used
Ammonia has been identified as a promising potential alternative fuel for future power generation. It is considered a candidate vector for power generation and has gained significant interest in recent times. Ammonia is difficult to ignite and requires a minimum ignition energy of 680 mJ, whereas other flammable gases like methane, ethane, propane, and hydrogen gas require significantly less energy to ignite. Ammonia also has a low flame propagation of about 8 cm/s.
Due to the challenges in igniting ammonia, a "pilot fuel" with a lower minimum energy for ignition, such as diesel fuel, is often used in conjunction with ammonia. This means that two fuels need to be managed, and the use of a pilot fuel does not entirely eliminate the potential for GHG emissions.
While ammonia can burn and be used as fuel, it is challenging to process in a typical engine. Engines may need to be adjusted or upgraded to utilize ammonia as fuel, and even then, smooth engine operation is not guaranteed. Additionally, ammonia is highly reactive and toxic, and it can cause corrosion in engines and gas tanks that contain metals like zinc, copper, brass, alloy, or brass alloys.
The use of ammonia as a fuel has several challenges, including low flammability, high NOx emissions, and low radiation intensity. However, recent advancements in ammonia combustion technology and its underlying chemistry have led to successful applications in gas turbines and industrial furnaces.

It is unlikely to be a viable alternative to fossil fuels due to its high cost
Adding ammonia to someone's fuel tank may cause the engine to stall or shut down. While ammonia can burn like fuel, it is challenging to combust in a typical engine. It is also highly toxic and corrosive, and can cause metals such as zinc, copper, brass, and alloys to corrode.
Ammonia has been considered as an alternative to fossil fuels, and it has gained significant interest recently. It is seen as a promising potential alternative fuel for future power generation, particularly in the maritime transport industry. However, it is unlikely to be a viable alternative to fossil fuels due to its high cost. While ammonia can be made from hydrogen derived from water using renewable or low-emission electricity, the cost is currently prohibitive. Even black ammonia, which is produced using fossil fuels, costs more per joule than fossil fuels. Green ammonia, which is produced using renewable energy, costs even more.
The high cost of green ammonia is due to the high price of green hydrogen as a feedstock. While the private sector is working to drive down costs, it is estimated that the industry will require US$150 billion in subsidies by 2030 and far more overall investment. However, if the hydrogen economy is fully developed, it is estimated to be a US$12 trillion market.
In addition to the high cost, there are other challenges associated with using ammonia as a fuel. Ammonia is highly toxic and corrosive, and it is difficult to ignite, so a "pilot fuel" such as diesel is often used alongside it. Ammonia combustion can also produce greenhouse gas emissions, and if nitrogen is lost as N2O during combustion, it could produce more emissions than coal.
While ammonia may not be a perfect alternative to fossil fuels, it is still an important part of the transition to a more sustainable economy. It is used as a feedstock for fuel cells and has applications in agriculture and various industrial processes. With further research and innovation, ammonia may become a more viable alternative to fossil fuels in the future.
