China Petroleum & Chemical Corporation (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. The operation model leverages green electricity generated from a floating photovoltaic power station to split seawater into hydrogen and oxygen, with the hydrogen seamlessly integrated into the refinery's pipeline network. Seawater hydrogen production offers a solution for utilizing renewable energy in coastal regions and the resourceful utilization of industrial wastewater. Challenges such as salt content and impurities in seawater have been overcome through specialized equipment innovations, showcasing Sinopec's commitment to advancing hydrogen technology. With milestones like deploying megawatt-scale electrolyzers and commissioning solid oxide electrolysis projects, Sinopec aims to lead in the hydrogen energy sector through research and application advancements.
