Recently, the shipboard ammonia fuel supply system (AFSS) independently developed by Shanghai Qiyao Environmental Technology Co., Ltd. (hereinafter referred to as “Qiyao Environmental”), a subsidiary of China State Shipbuilding Corporation Limited, successfully received the Approval in Principle (AiP) certificate issued by DNV. This system integrates high-pressure and low-pressure ammonia fuel supply systems and is equipped with key ammonia reliquefaction units and ammonia treatment units, establishing a complete system for ammonia fuel conditioning and safety control.
Ammonia fuel is widely regarded as one of the most promising alternative fuels for the shipping industry to achieve a green and low-carbon transition, and its core equipment—the shipboard ammonia fuel supply system—has attracted extensive attention from the shipping industry. Leveraging rich development experience in the field of clean fuels, Qiyao Environmental has made breakthroughs in key technologies such as ammonia fuel bunkering, transportation, ammonia capture and recovery, and safety protection. It has completed the development of a series of core equipment ranging from low-pressure gas supply systems to high-pressure liquid supply systems, providing customers with integrated solutions capable of adapting to all operating conditions. Currently, the low-pressure ammonia fuel supply system has completed testing with an ammonia-fueled engine independently developed by CSSC’s 711 Research Institute, achieving a cumulative stable operation of over 600 hours, fully verifying the reliability of the technology. The ammonia fuel supply system independently developed by Qiyao Environmental possesses strong scenario adaptation capabilities, able to meet the differentiated needs of various users and ship types.
In the future, Qiyao Environmental will continue to adhere to technological innovation to lead industrial development, promote the research, development, application, and iterative upgrading of green ship technologies, and provide global customers with comprehensive collaborative solutions for reducing ship greenhouse gases and pollutants from the “fuel end” to the “exhaust end,” jointly accelerating the green and low-carbon transition of the shipping industry.
