Chinese car company GAC made a groundbreaking announcement by unveiling an ammonia-fueled engine for small passenger vehicles at their annual technology event in Beijing. The 2-liter model boasts an output of 120 kilowatts and emits significantly less carbon than traditional gas and diesel engines, positioning it as a sustainable green energy solution. Qi Hongzhong from GAC's research and development division highlighted the combustion capacity of ammonia and its potential value for society. Despite challenges like lower energy density, safety concerns, and infrastructure requirements, the use of ammonia in cars is seen as a promising development. While the automotive industry primarily focuses on electric vehicles, GAC's foray into hydrogen and now ammonia engines showcases a commitment to diverse green fuel technologies. Ammonia, traditionally utilized in shipping and trucking sectors, is now being explored in other industries with ongoing research efforts to enhance its properties. The path towards making ammonia a practical energy option for commercial passenger vehicles requires further research and development, but the potential for a viable fuel alternative is promising with continued input from various sectors.
