The article discusses the escalating global municipal solid waste (MSW) quantities and the associated socio-environmental challenges, emphasizing the need for innovative solutions like Waste-to-Hydrogen (WTH) technology. It introduces the Two-Stage Gasification-Reforming (TSGR) process as an emerging technology for upcycling MSW to produce hydrogen, aiming to alleviate waste management burdens and support the growing hydrogen economy. The review focuses on optimizing process control and catalytic efficiency to enhance hydrogen production. It also explores the integration of chemical and calcium looping into TSGR processes to increase hydrogen output, reduce catalyst costs, and improve system performance. Additionally, the article highlights the current state of techno-economic analysis for WTH technology, outlining challenges and future research directions. Despite industrial-scale challenges such as efficiency enhancement and catalyst development, the review provides insights into advancing Waste-to-Hydrogen technology towards practical implementation, aiming to bridge the 'green hydrogen gap' and contribute to a more sustainable and resource-efficient waste management approach.
