China's first integrated offshore hydrogen-ammonia-methanol project has commenced its trial operation phase in Yantai, Shandong province. This collaborative project involves CHN Energy Hydrogen Energy Technology, CIMC Raffles, and Guoneng Hydrogen Innovation Technology (Beijing). With a primary focus on producing clean fuels for ships, the initiative showcases the nation's initial comprehensive demonstration of offshore hydrogen production, storage, transportation, and utilization along the entire industrial chain. The project's core component is a semi-submersible offshore hydrogen production platform exceeding 50 meters in height and over 20,000 tons in weight. The platform is equipped with photovoltaic power generation systems, electrochemical energy storage devices, and three hydrogen production units, including seawater and freshwater electrolysis systems. Moreover, it features a desalination module capable of generating five tons of freshwater daily for hydrogen production. The hydrogen produced is further transformed into methanol and ammonia to overcome storage and transportation challenges. By utilizing offshore renewable energy for off-grid hydrogen production, the project plays a crucial role in converting green hydrogen into ammonia and methanol, serving as clean marine fuels and essential industrial raw materials. The construction of the project commenced in September 2024, with the completion of construction achieved on March 27. Furthermore, the project successfully passed the China Classification Society's (CCS) design compliance review in January 2025. This milestone marks significant progress in establishing technical specifications and standards for China's offshore hydrogen production sector, addressing regulatory and operational framework gaps.
