Hydrogen is a versatile energy vector with significant potential for sustainable energy production. However, its production from waste/residues is often overlooked. Gasification of waste, such as municipal solid waste (MSW), tires, and plastics, offers an attractive alternative to produce renewable hydrogen. This review summarizes recent developments in waste gasification technologies and provides an overview of suitable gasification processes. A literature survey indicates that hydrogen productivity ranges from 15 to 300 g H₂/kg of feedstock, depending on the feedstock. Suitable gas treatment methods, including direct and indirect (chemical looping) concepts, are also covered. Hydrogen production via gasification has high productivity potential, but regulations and subsidies are necessary to bring the technology to market. The gasification process converts solid carbonaceous materials into combustible gases (H₂, CO, CH₄, CO₂) in the presence of a gasification agent (e.g., air, oxygen, steam) at temperatures of 550–1000 °C. The process involves several stages, including dehydration, pyrolysis, partial oxidation, and reduction. The main reactions in gasification include oxidation and methanation, which are exothermic and can be maintained at high temperatures. Steam addition allows tars to react via steam reforming, improving hydrogen and syngas purity. The use of catalysts and sorbents enhances tar removal and hydrogen production. Studies on MSW gasification show that hydrogen yields range from 37.7 to 41.36 g/kg MSW, depending on temperature, equivalence ratio (ER), and residence time. The use of catalysts, such as calcined dolomite and Ni-based catalysts, significantly increases hydrogen production. For example, calcined dolomite can achieve a hydrogen yield of 77.3 g/kg MSW at 950 °C, while Ni-based catalysts can achieve yields of up to 68 g/kg WP. The use of steam and catalysts also reduces tar content and improves syngas quality. Waste tires (WTs) contain non-decomposable and non-biodegradable components that pose environmental and health risks. However, gasification of WTs can produce hydrogen and syngas, with hydrogen yields ranging from 158 to 387 g/kg. The use of catalysts and steam can enhance hydrogen production and reduce tar content. Similarly, waste plastics (WPs) can be gasified to produce hydrogen and syngas, with hydrogen yields ranging from 15 to 300 g/kg. The use of catalysts and steam improves hydrogen production and reduces tar content. Overall, gasification of waste materials offers a promising alternative for renewable hydrogen production. However, further research and development are needed to optimize gasification processes, reduce costs, and improve hydrogen purity.
