Ammonia as a Fuel: The Chemistry and Potential Impact

TLDRAmmonia, once used solely as fertilizer, can be burned as a fuel in engines. Toyota has developed an internal combustion engine based on ammonia that reduces carbon emissions by 90%. Ammonia combustion has certain advantages and challenges compared to gasoline. Its flame speed is slower, but it produces no carbon emissions. Adding a chemical promoter can increase its flame speed to match gasoline. However, ammonia is corrosive and toxic, requiring careful handling and safety measures. Despite these challenges, ammonia combustion has the potential to significantly impact climate change.
