China Petroleum & Chemical Corporation's (Sinopec) has completed a groundbreaking project at its Qingdao Refinery, establishing China's first factory-based seawater hydrogen production facility. This project, which combines direct seawater electrolysis with renewable energy, has the capacity to produce 20 cubic meters of green hydrogen per hour. By utilizing green electricity from a photovoltaic power station, Sinopec efficiently splits seawater into hydrogen and oxygen, with the hydrogen seamlessly integrated into the refinery's operations. This approach not only provides a sustainable solution for green hydrogen production in coastal areas but also showcases the resourceful use of high-salinity industrial wastewater. Seawater hydrogen production offers immense potential by converting unstable renewable energy into a more manageable form, while also conserving freshwater resources. Sinopec, in collaboration with the Dalian Institute of Petroleum and Petrochemicals, overcame challenges like salt content and impurities in seawater through innovative equipment and process designs. The company's focus on hydrogen technologies is evident through milestones like deploying a megawatt-scale PEM electrolyzer and commissioning China's first 100-kilowatt Solid Oxide Electrolysis Cell (SOEC) project. Looking ahead, Sinopec is poised to drive growth in the hydrogen energy sector with plans for numerous hydrogen refueling stations and fuel supply centers by 2024. By spearheading research and application of hydrogen technologies, Sinopec aims to position itself as a leading hydrogen energy company in China, emphasizing sustainability and innovation in the energy sector.
