On Wednesday, China Petroleum and Chemical Corp completed the nation’s first factory-based seawater hydrogen production research project in Qingdao, Shandong province. The project, combining seawater electrolysis with green electricity, can produce 20 cubic meters of green hydrogen per hour. This achievement is a significant step in China’s efforts towards clean energy technology and sustainable resource utilization. By integrating the produced green hydrogen into the refinery’s operations and fueling hydrogen-powered vehicles, the project showcases a new approach to utilizing renewable energy in coastal regions. Green hydrogen, generated using renewable energy sources, is expected to dominate China’s hydrogen supply by 2060, accounting for 90 percent. The project's success demonstrates the potential of direct seawater electrolysis, leveraging abundant coastal renewable energy. While challenges like corrosion from seawater impurities exist, Sinopec has developed key equipment and processes to address these issues. China, a global leader in hydrogen production, aims to triple its hydrogen production to 100 million tons by midcentury. Industry experts anticipate an industry transformation fueled by declining costs and policy support. The project's completion highlights the country's commitment to advancing green hydrogen technology. By leveraging its coastal resources and overcoming technical challenges, China is paving the way for large-scale industrial application of seawater hydrogen production in the future.
