China Petroleum & Chemical Corporation's Sinopec has achieved a significant milestone by completing China's first factory-based seawater hydrogen production research project at its Qingdao Refinery. This innovative project combines direct seawater electrolysis with renewable energy to produce 20 cubic meters of green hydrogen per hour. The green hydrogen is seamlessly integrated into Qingdao Refinery's operations for refining processes and hydrogen-powered vehicles, highlighting the efficiency and stability of the factory-based operation. Seawater hydrogen production holds immense promise as it transforms unstable renewable energy into a more manageable form, green hydrogen, while also preserving freshwater resources. Despite challenges like salt content and impurities in seawater, Sinopec, in collaboration with the Dalian Institute of Petroleum and Petrochemicals, has successfully addressed these issues through specialized equipment and process designs. The company's advancements in seawater hydrogen production underline its commitment to driving growth in the hydrogen energy industry. Sinopec's efforts extend beyond this project, with achievements like deploying megawatt-scale PEM electrolyzers and commissioning China's first 100-kilowatt Solid Oxide Electrolysis Cell (SOEC) project. By focusing on establishing hydrogen refueling stations and fuel supply centers, Sinopec aims to lead China's hydrogen energy sector. The company's dedication to research, innovation, and sustainability solidifies its position as a key player in shaping the future of green hydrogen production and utilization.
