China Petroleum and Chemical Corp, also known as Sinopec, has completed the nation's first factory-based seawater hydrogen production research project in Qingdao, Shandong province. This project marks a significant advancement in clean energy technology and sustainable resource utilization. By combining direct seawater electrolysis with green electricity, the project can produce 20 cubic meters of green hydrogen per hour, providing a new solution for utilizing renewable energy in coastal areas. The green hydrogen produced is integrated into the refinery's pipeline network for refining operations or fueling hydrogen-powered vehicles. Experts believe that China is on the path to becoming a global leader in green hydrogen production and utilization, driven by decreasing costs, supportive policies, and technological innovation. Green hydrogen, produced using renewable sources like solar and wind power, is expected to dominate China's hydrogen supply in the future. Although seawater electrolysis poses technical challenges due to seawater's composition, Sinopec has developed specialized equipment and technologies to address these issues. As technology advances and costs decrease, seawater hydrogen production is expected to see widespread industrial application in the future, with China actively researching and overcoming technical hurdles in this field.
