一电两用、一水双收 我国科研人员突破海水制氢提镁联产技术

Core Viewpoint - The collaboration between Hainan University and the Ningbo Institute of Materials Technology and Engineering has led to a breakthrough in the direct electrolysis of natural seawater for hydrogen production, significantly reducing production costs and enabling the co-production of hydrogen and magnesium hydroxide [1][3]. Group 1: Technology and Innovation - A new type of electrode, resembling a "non-stick pan," has been developed to prevent magnesium hydroxide from depositing on the electrode surface during the electrolysis of seawater, thus enhancing the stability and longevity of the electrode [1][3]. - The new technology operates at room temperature and allows for the co-production of high-purity hydrogen and magnesium hydroxide, with production costs lower than traditional high-energy-consuming methods [3]. Group 2: Economic Impact - Experimental data indicates that for every kilogram of hydrogen produced, approximately 15 kilograms of high-purity magnesium hydroxide can be extracted, which can offset the hydrogen production costs [3]. - This breakthrough technology is expected to facilitate the low-cost mass production of "green hydrogen," contributing to the renewable energy sector [3].
