Dihydrogen (H 2 ) constitutes a promising energy carrier for transporting part of the world's energy demand and concomitantly for reducing toxic emissions. Water electrolysis powered by renewable energy would provide H 2 with a small carbon footprint. To save global fresh water, seawater electrolysis has attracted much attention in recent years, since it represents 96.5% of the Earth's resources and is abundant worldwide. However, seawater's composition is complex, which poses problems for direct seawater splitting. To date, seawater splitting usually requires a two-step process, i.e., purification of seawater using reverse osmosis (RO) which represents 69% of the globally produced desalinated water (Jones et al. Sci. Total Environ. 2019, 657, 1343−1356 and then electrolysis of pure water. This involves two separate processes, resulting in a complex design and significant space requirement for their corresponding equipment. Recently, efforts have been made to use seawater directly for H 2 production, and electrolyzers using this water source are being developed. The objective of this review is to describe first the impact of direct seawater splitting on water electrolysis technologies and then to present the most recent innovative approaches to avoid pretreatment with particular emphasis on innovative configurations of well-established industrial electrolyzers and new original approaches. Finally, as a conclusion, we will propose perspectives toward the development of electrolyzers enabling the electrochemical production of H 2 from seawater for sustainable development.

Forward osmosis (FO) has emerged as a highly promising and energy‐efficient technology for seawater desalination. This study investigates the enhancement of polyethersulfone/polysulfone FO membranes by incorporating graphene oxide (GO) for seawater desalination. The effects of different GO concentrations on membrane properties and FO desalination performance were examined. Among the tested membranes, the one with 0.04 wt% GO exhibited optimal hydrophilicity, as indicated by a lower contact angle (53.93° ± 5.61°), higher porosity (69.86 ± 0.66), and a minimal structure parameter (312.33 μm). The GO.04 membrane demonstrated significantly improved water flux (Jw) of 106 L/m2 h and low reverse salt flux (Js) of 0.69 g/m2 h. Compared to the GO0 membrane without GO, the water flux was 103% higher without compromising salt selectivity (Js/Jw = 0.0065 g/L) when using distilled water as the feed solution (FS) and 1 M NaCl as the draw solution. However, over a threshold of 0.09%, GO concentration on membrane surfaces and pores can impede water flow, reducing porosity and increasing resistance to membrane transport. The GO.04 membranes also exhibited high water flux (113, 94.28, and 84.64 L/m2 h) when brackish water with different NaCl concentrations (5000, 10,000, and 15,000 mg/L) was used as the FS. Moreover, under real seawater conditions from the Suez Canal, the GO.04 FO membrane showed a significantly higher water flux of 94.3 L/m2 h. These findings provide valuable insights into the desalination of actual seawater from the Suez Canal, offering significant potential for the advancement of water treatment and resource management practices.
