China's First Factory-Based Seawater Hydrogen Production Project Completed at Sinopec Qingdao Refinery
Seawater hydrogen production holds significant potential. By directly converting seawater into hydrogen, unstable and hard-to-store renewable energy can be transformed into green hydrogen, which is relatively easier to store and utilize. Moreover, this process conserves precious freshwater resources, offering a new pathway for the development of the hydrogen energy industry.
Despite its advantages, seawater hydrogen production comes with challenges. Seawater contains approximately 3% salt, and impurities, such as chloride ions, can corrode electrolytic electrodes, while cation deposits may clog equipment channels, reducing efficiency and causing damage. Sinopec Qingdao Refinery, in collaboration with the Dalian Institute of Petroleum and Petrochemicals, has successfully overcome these challenges through a series of specialized equipment innovations and unique process designs, including chlorine-resistant electrode technology, high-performance electrode plate design, and a seawater circulation system, enabling a seamless integration of research and practical applications.
Seawater hydrogen production is expected to achieve large-scale industrial applications in the future. Sinopec is accelerating its efforts to become
China's leading hydrogen energy company by advancing the research and application of hydrogen technologies across the entire industry chain.
Sinopec has already achieved several milestones, including the successful deployment of a megawatt-scale PEM electrolyzer and the commissioning of China's first 100-kilowatt Solid Oxide Electrolysis Cell (SOEC) project. By 2024, the company has established 136 hydrogen refueling stations, and built 11 hydrogen fuel supply centers, underscoring its commitment to driving high-quality growth in the hydrogen energy sector.
