The world's first pure ammonia-powered demonstration vessel, named "Anhui," has successfully completed its maiden voyage in Hefei, Anhui Province, China. This milestone represents a key advancement in green shipping technology. The vessel is equipped with a 200-kilowatt high-speed gas internal combustion generator, two 100-kilowatt propulsion electric motors, and a dual-propeller system, capable of carrying a full load of 50 tons and achieving a rated speed of 10 knots. The "Anhui" was jointly developed by the Institute of Energy and highlights progress toward the industrial application of ammonia fuel in maritime transport. Additionally, China has launched its largest green hydrogen-ammonia integrated project in Chifeng, Inner Mongolia, with a first-phase annual production capacity of 320,000 tons of green synthetic ammonia. This project is powered by 1.43 million kilowatts of wind and solar energy and supported by a 680-megawatt-hour energy storage system, marking a transition from demonstration to commercial-scale operations in the green hydrogen-ammonia sector. Furthermore, China delivered the world’s first sail-assisted oil tanker to a UK company, which is expected to reduce carbon dioxide emissions by 5,000 tons annually. In the northeast region, the first domestic bonded green methanol fuel ship-to-ship bunkering operation was completed in Liaoning, transferring 500 tons of green methanol fuel to China’s first methanol dual-fuel container ship, reducing CO2 emissions by more than 800 tons compared with traditional fossil fuels. These developments underscore China’s expanding leadership in sustainable maritime technologies and green fuel applications.
