While hydrogen is a leading candidate, existing literature often treats technological, environmental, and policy dimensions in isolation, creating a fragmented understanding of its true sustainability. This review employs a systematic analysis of over 250 peer-reviewed sources and international policy frameworks (2015–2025) to synthesize production pathways ranging from thermochemical (SMR, gasification) to electrochemical and biological methods. Evaluation is conducted through a multi-dimensional lens focusing on Carbon Intensity (CI), Circular Economy (CE) metrics, and alignment with UN Sustainable Development Goals (SDGs 7, 9, and 13). Our findings demonstrate that while green hydrogen offers near-zero operational emissions, its lifecycle sustainability is contingent upon \"Green Chemistry\" innovations in membrane materials and catalysts to reduce rare-earth mineral dependency. Comparative analysis reveals that \"Blue\" hydrogen acts only as a bridge, as its long-term viability is limited by methane leakage and carbon capture efficiencies (&lt;90%). Furthermore, we identify a critical \"policy-technology\" gap: current global frameworks lack standardized lifecycle assessment (LCA) protocols, which hinders international trade and sustainable finance. This review contributes a novel integrated framework that bridges the gap between laboratory-scale innovations and macro-level policy. We conclude that achieving a net-zero future requires not just \"clean\" production, but a circular hydrogen economy that prioritizes material recovery and harmonized global certification standards.</div></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"9 ","pages":"Article 100191"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146037476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
