Collectively, these directions establish a coherent roadmap linking mechanistic understanding with advancement and system-scale feasibility. Positioning ERNH alongside N₂ and NO electroreduction highlights its distinct advantage: it couples nitrate remediation with the sustainable production of nitrogen-based chemicals under comparatively accessible energetic and mechanistic conditions. By uniting interfacial microenvironment control, cascade catalysis, and integrated reactor engineering, ERNH can progress beyond proof-of-concept demonstrations toward deployment in nitrate remediation and value-added nitrogen chemical manufacturing. Realizing this vision would not only provide a safer and sustainable route to nylon and pharmaceutical precursors, but would also position electro-synthetic NH₂OH as a strategic pillar in circular nitrogen management and global carbon-neutral chemical production.
