China Petroleum & Chemical Corporation (Sinopec) has achieved a notable feat by completing the country's first factory-based seawater hydrogen production research project at its Qingdao Refinery. This project, integrating direct seawater electrolysis with renewable energy, has enabled the facility to produce twenty cubic meters of green hydrogen per hour. By utilizing high-salinity industrial wastewater and green electricity from a floating photovoltaic power station, Sinopec has demonstrated an innovative solution for green hydrogen production along coastal regions. The process not only converts seawater into green hydrogen but also ensures operational stability and efficiency through advanced equipment innovations. Despite challenges like salt content and electrode corrosion, Sinopec's collaboration with the Dalian Institute of Petroleum and Petrochemicals has led to technological advancements, making seawater hydrogen production a viable industrial application for the future. Through ongoing commitments and projects like megawatt-scale electrolyzers and hydrogen refueling stations, Sinopec is driving the growth of China's hydrogen energy industry, emphasizing sustainable solutions and technological progress.
