Green hydrogen production from renewably powered water electrolysis is considered as an ideal approach to decarbonizing the energy and industry sectors. Given high-cost supply of ultra-high-purity water, well mismatched distribution sources renewable energies, combining seawater with coastal solar/offshore wind power attracting increasing interest for large-scale green production. However, various impurities in lead corrosive toxic halides, hydroxide precipitation, physical blocking, which will significantly degrade catalysts, electrodes, membranes, thus shortening stable service life electrolyzers. To accelerate development electrolysis, it crucial widen working potential gap between oxygen evolution chlorine reactions develop flexible highly efficient purification technologies. In this review, we comprehensively discuss present challenges, research efforts, design principles direct/indirect aspects materials engineering system innovation. Further opportunities developing advanced integrated electrolyzers are highlighted both low-grade sources.

Abstract The chloride ions in seawater result corrosion, low catalytic efficiency, and poor stability of the electrocatalysts direct electrolysis, which limits use large‐scale electrolysis technology. Herein, a corrosion‐resistant Ag/NiFeRu layered double hydroxide (LDH) electrocatalyst for at industrial current density, Ru Ag species catalyst can have corrosion‐resistance from anode surface enhance its robustness is designed. requires overpotentials 256 287 mV to obtain density 1 A cm −2 m KOH + seawater, respectively. More importantly, it works stably over 1000 h alkaline seawater. Further quasi‐industrial conditions measurement (6 60 °C) shows markedly overpotential 174 on LDH, obtaining 140 under harsh conditions. Theoretical calculations demonstrate that effectively regulate local electronic structure NiFe intrinsic activity LDH. transformation 2 O during OER stabilizes Fe site improves overall electrocatalyst.
