China Petroleum & Chemical Corporation's (Sinopec) has successfully completed China's first factory-based seawater hydrogen production project at its Qingdao Refinery. This innovative project integrates direct seawater electrolysis with renewable energy-powered green hydrogen production, achieving an hourly output of 20 cubic meters of green hydrogen. By converting seawater into hydrogen, the project not only offers a solution for utilizing renewable energy in coastal regions but also presents a new approach for resourceful utilization of high-salinity industrial wastewater. The process involves splitting seawater into hydrogen and oxygen through electrolysis, with the hydrogen seamlessly integrated into the refinery's pipeline network for use in refining processes or hydrogen-powered vehicles. Challenges such as seawater's salt content and impurities were addressed through specialized equipment innovations. Sinopec aims to lead in hydrogen energy by advancing hydrogen technologies and has already achieved significant milestones, including deploying a megawatt-scale PEM electrolyzer and commissioning China's first 100-kilowatt Solid Oxide Electrolysis Cell (SOEC) project. The company plans to establish more hydrogen refueling stations and fuel supply centers, emphasizing its commitment to driving growth in the hydrogen energy sector.
