a Schematic diagram of three strategies including extraction of Mg(OH)2 from seawater, H2 production via seawater electrolysis and extraction of Mg(OH)2 coupled with H2 production from seawater. b Internal construction of the 100 cm2 flow-type electrolyzer. c Stability tests of the natural seawater electrolyzer under 100 mA cm−2 at 25 °C, with the inset showing the Mg(OH)2 obtained during this process. d OH− availability of chemical precipitation and seawater electrolysis to synthesis Mg(OH)2. e Brief division of natural seawater electrolysis total costs and benefits. f Life Cycle Assessment (LCA) of the seawater electrolysis-based magnesium extraction and hydrogen production process. Source data for Fig. 5 are provided as a Source Data file.
