Let’s give a thumbs up and encouragement to the achievements made in China’s chemical technology and equipment sector. Your participation in the discussion is the greatest motivation for us! ********************** [Ten Years of Great Development in Chemical Equipment] This is a continuously updated compilation post; all are welcome to join the discussion: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** China’s first integrated offshore hydrogen-ammonia-methanol project has been completed. Source: China Chemical Industry News, March 28, 2025. According to Sinochem New Network, on March 27, China’s first integrated offshore hydrogen-ammonia-methanol project was completed in Yantai, Shandong Province. It has now entered the commissioning phase, laying the foundation for the project’s operation and for conducting comprehensive tests on the entire process of offshore hydrogen production. 　　This project was jointly developed by **Energy Group Hydrogen Technology Co., Ltd., Yantai CIMC Raffles Offshore Engineering Co., Ltd., and Guoneng Hydrogen Innovation Technology (Beijing) Co., Ltd.** It is the first domestic demonstration project covering the entire chain of hydrogen production, storage, transportation, and utilization in marine environments. The project is located 5 kilometers off the coast to the east of Yantai City, Shandong Province. It features China’s first semi-submersible offshore hydrogen production platform, which is over 50 meters tall and weighs more than 20,000 tons. This platform enables the production of hydrogen using offshore renewable energy sources, and it is also capable of converting green hydrogen into ammonia and methanol, which are easier to store. It has the potential to serve as an offshore fuel refueling station for ocean-going vessels in the future. 　　The reporter learned that this one-stop offshore green hydrogen, methanol, and ammonia production system will be mounted on a semi-submersible offshore platform. By utilizing the existing offshore floating photovoltaic systems and energy storage facilities, it will conduct research on key technologies such as off-grid photovoltaic electrolysis for hydrogen production, high-pressure hydrogen storage, the synthesis of green methanol and green ammonia, and control of off-grid systems. This approach aims to create an integrated process flow that links offshore green hydrogen production with downstream hydrogen-based chemical manufacturing, thereby making significant strides toward the development of comprehensive offshore green energy sources and the establishment of offshore energy hubs. 　　**Liu Congmin, general manager of HydroGen Innovation Company under the energy group Guohua Investment, said, “Since there are significant differences between hydrogen production at sea and on land, the relevant regulations and standards are still lacking.” The greatest significance of this platform lies in its ability to conduct empirical testing of the entire process of hydrogen production at sea, providing technical support for establishing industry standards for the development of marine hydrogen energy. ” 　　At the International Symposium on Marine Hydrogen Development Technologies and Applications, held concurrently with the 2025 International Hydrogen Energy Conference on March 27, Liu Wei, Secretary-General of the China Hydrogen Energy Alliance, Director of the Hydrogen Energy Division of **Energy Group, and General Manager of Guohua Investment (Hydrogen Energy Company), said that the three main application areas for marine hydrogen are: coastal \"semi-marine/semi-land\" systems that utilize sea wind and land-based resources to assist in industrial decarbonization; offshore \"fully marine\" integrated energy hubs that utilize hydrogen, ammonia, and alcohol; and \"zero-carbon island\" solutions that rely on integrated marine hydrogen energy supply. **The energy group is advancing a three-phase strategy for marine hydrogen energy. The first phase focuses on the project of producing hydrogen/ammonia/alcohols using floating photovoltaic platforms at sea in Yantai, Shandong; by conducting experiments with electricity, hydrogen, and alcohols at sea, the entire technical chain is established, thereby creating a comprehensive system for the production, storage, transportation, and utilization of marine hydrogen energy, as well as a demonstration project for the production of hydrogen from marine renewable energy sources and its integrated utilization ； In the second phase, up to 2027, a semi-submersed megawatt-class hydrogen production and hundred-ton alcohol synthesis project utilizing offshore wind and solar power will be built in Yancheng, Jiangsu ； In Phase 3, by 2030, a project is planned to develop floating thousand-ton-class offshore wind turbines in the deep waters of the South China Sea for producing green hydrogen-based fuels.
