China has made a significant impact in the realm of green shipping with the successful launch of the 'Anhui,' the world's first vessel powered solely by ammonia fuel. Developed in Hefei, Anhui Province, this 50-tonne ship marks a crucial step towards carbon-free marine transport. Equipped with a 200kW ammonia-fueled generator and two 100kW propulsion motors, the vessel achieved speeds of 10 knots in its maiden voyage, showcasing stable propulsion and reduced emissions. The research team in Hefei overcame challenges related to ammonia combustion through innovations in plasma ignition and catalytic cracking, enabling efficient hydrogen-ammonia mixed combustion. This breakthrough allows for near-zero CO₃ emissions and controlled nitrogen oxide output, validating ammonia's potential for industrial applications. The success of the 'Anhui' vessel signifies a major advancement in carbon-neutral maritime transport, providing a scalable and efficient green alternative for the shipping industry. Experts see the potential for this technology to revolutionize global marine transport, aligning with China's clean energy goals and international emissions regulations.
