Hydrogen purity plays a crucial role in the expanding hydrogen economy, particularly applications such as fuel cells and industrial processes. This review investigates relationship between production methods resulting levels, emphasizing differences reforming, electrolysis, biomass-based techniques. Furthermore, it explores state-of-the-art purification technologies, including pressure swing adsorption (PSA), membrane separation, cryogenic distillation, highlighting their effectiveness limitations achieving ultra-pure hydrogen. Analytical gas chromatography, mass spectrometry, cavity ring-down spectroscopy are also discussed terms of accuracy application scope for quality assessment. By integrating findings from global domestic studies, this paper aims to provide comprehensive understanding challenges advancements purity, offering insights into optimizing sustainable energy future.
