China Petroleum & Chemical Corp. has completed China's first factory-based seawater hydrogen production research project in Qingdao, Shandong province. The project combines direct seawater hydrogen production with green electricity from a floating photovoltaic power station to produce 20 cubic meters of green hydrogen per hour. This innovative approach offers a new solution for utilizing renewable energy in coastal areas and a pathway for recycling high-salinity industrial wastewater. The entire production process, from electrolyzing seawater into hydrogen and oxygen to integrating the produced hydrogen into the refinery's pipeline network for refining operations or fueling hydrogen-powered vehicles, is conducted within the factory. Green hydrogen, generated using renewable sources like solar and wind power, is known for its minimal greenhouse gas emissions during production, aligning with sustainability goals.
