China Petroleum & Chemical Corporation, Sinopec, has achieved a significant milestone by completing China's first factory-based seawater hydrogen production project at its Qingdao Refinery. Through direct seawater electrolysis powered by renewable energy, the refinery now produces 20 cubic meters of green hydrogen every hour. This approach not only offers a new method for coastal regions to leverage renewable energy for green hydrogen but also presents a means to effectively utilize high-salinity industrial wastewater. The project's factory-based operation model, utilizing green electricity from the refinery's floating photovoltaic power station, ensures efficiency and stability in the hydrogen production process. Seawater hydrogen production has vast potential as it transforms unstable renewable energy into a more manageable form, while also conserving freshwater resources. Despite challenges like salt content and impurities in seawater, Sinopec, in collaboration with the Dalian Institute of Petroleum and Petrochemicals, has successfully overcome these obstacles with specialized equipment innovations. The company is focused on driving the industrial application of seawater hydrogen production, aiming to lead in hydrogen energy by deploying advanced technologies and establishing numerous hydrogen refueling stations by 2024. Sinopec's commitment underscores its dedication to sustainable growth in the hydrogen energy sector.
