Abstract Developing cost‐effective hydrogen evolution reactions (HER) catalysts to replace Pt/C in alkaline seawater media remains a critical challenge. Therefore, the osmium‐osmium phosphide (Os‐OsP 2 ) catalyst is reported with heterogeneous junction through ultrafast (20 s) microwave quasi‐solid approach for seawater‐splitting under industrial‐grade current density. Experimental and theoretical analysis reveal that Os‐OsP₂ interface optimizes electronic structure: osmium (Os) sites accelerate water dissociation by lowering d‐band center, while OsP₂ promotes desorption via interfacial spillover, collectively reducing HER energy barrier. In addition, requires only 1.74 V reach 1 A cm −2 owns high price activity anion exchange membrane electrolyzer, surpassing commercial 23% efficiency identical conditions. Furthermore, it exhibits robust across wide pH range exceptional durability over 100 h seawater. Economic evaluation highlights its superior cost (85.6 dollar⁻¹), 90‐fold higher than Pt/C, production costs ($0.86 GGE⁻¹) undercutting U.S. DOE target. This study provides feasible guidance development of high‐performance, scalable from
