Chinese auto manufacturer GAC has made a remarkable stride in the automotive sector by unveiling the first ammonia-powered engine for cars. The 2.0-liter engine can generate 120 kW of electricity while cutting carbon emissions by 90% in comparison to traditional gas-driven vehicles. GAC introduced this innovation at its annual technology event in Beijing, where it showcased other breakthroughs like an eVTOL aircraft and an intelligent driving system. The company's move towards using ammonia as a clean energy source aligns with its commitment to reducing greenhouse gas emissions. While ammonia has been predominantly used in shipping and trucking due to handling complexities, its potential in passenger vehicles is highlighted by GAC's groundbreaking engine. Despite challenges in safe storage and handling, the industry's focus on electric vehicles and hydrogen has not hindered the exploration of ammonia as a fuel alternative. The industry's interest in ammonia extends beyond GAC, with companies like Mitsubishi Shipbuilding Co. and startups like Amogy Inc. exploring its potential in various applications. Challenges in using ammonia for passenger cars persist, but advancements in technology and infrastructure could pave the way for its adoption. The future of sustainable transportation seems promising with innovations like the Emblème concept car by Renault, offering a hybrid EV-hydrogen fuel cell solution. While the road ahead may be challenging, collaborative efforts can drive the development of ammonia technology and infrastructure, contributing to a greener automotive future.
