China achieved a significant milestone in green maritime technology with the successful maiden voyage of the world's first ammonia-powered ship, the 'Anhui,' in Hefei, Anhui Province. Ammonia, known for its high energy density and zero carbon emissions upon combustion, is being explored as an alternative fuel for the shipping industry's decarbonization efforts. Countries like Japan and Norway have also invested in ammonia-powered vessels, with a 2021 International Energy Agency report suggesting that ammonia could supply a substantial portion of the shipping sector's energy needs by 2050 in a net-zero emissions scenario. The 'Anhui,' developed by the Institute of Energy of the Hefei Comprehensive National Science Center in collaboration with Shenzhen Haixu New Energy Co., Ltd., features advanced technologies like a high-speed ammonia-fueled internal combustion generator and propulsion motors, highlighting the potential of ammonia as a marine fuel. Researchers overcame critical hurdles related to stable ammonia combustion and demonstrated near-zero carbon emissions during the voyage, confirming the viability of ammonia-hydrogen fuels for marine applications. The successful voyage was hailed as a significant step towards a cleaner and low-carbon energy system for maritime transport by industry experts and officials. China's commitment to dual carbon goals will likely drive further advancements in clean energy technologies for the shipping sector.
