China has taken a significant step forward in the global hydrogen industry with the launch of its first green hydrogen production project based on seawater electrolysis. Sinopec's refinery in Qingdao has introduced a pioneering technology that integrates direct seawater electrolysis powered by renewable energy to produce up to 20 cubic meters of green hydrogen per hour. This breakthrough not only addresses the water scarcity issue by utilizing marine resources but also showcases innovative solutions to tackle seawater impurities through corrosion-resistant electrodes and optimized circulation systems developed in collaboration with the Dalian Institute of Petroleum and Petrochemicals. The project forms part of China's strategy to diversify its energy sources, emphasizing the shift towards sustainable alternatives and reducing reliance on fossil fuels. Qingdao's initiative serves as a model for other regions interested in adopting similar green hydrogen technologies, promoting a circular economy at a local level and supporting hydrogen-powered vehicles and industrial processes. Sinopec's long-term goal is to establish large-scale industrial hydrogen production, evidenced by the commissioning of a megawatt-scale PEM electrolyzer. By boosting domestic value chains and enhancing energy sovereignty, China aims to position itself as a leader in the green hydrogen sector, reducing energy import costs and paving the way for technological exports on a global scale.
