The world's first pure ammonia-powered vessel, named 'Anhui', completed its maiden voyage in Hefei, China, showcasing a significant advancement in green shipping. Developed by the Institute of Energy of the Hefei Comprehensive National Science Center and Shenzhen Haixu New Energy Co., Ltd., the vessel is powered by ammonia, a carbon-free fuel with high energy density. The use of ammonia in shipping is seen as a promising way to decarbonize the industry, as it only produces water and nitrogen when combusted. Despite facing challenges like ignition difficulties and unstable combustion, the successful voyage of the 'Anhui' demonstrated stable combustion of pure ammonia fuel with nearly zero carbon dioxide emissions and effective control of nitrogen oxides. The vessel is equipped with advanced technologies like a 200kW high-speed gas internal combustion generator, two 100kW propulsion motors, and a twin-screw propulsion system, enabling it to operate efficiently. Experts believe that the success of the ammonia-powered vessel signifies a major milestone in creating a clean, low-carbon energy system for water transport. They highlight the potential for ammonia-hydrogen fuels to be widely utilized in various sectors, including marine and land transport, industrial boilers, and fuel cells. The development and deployment of pure ammonia engines at the megawatt level are expected to have a significant impact on achieving China's dual carbon goals.
