Resumo(s)
Hydrogen is a versatile energy vector for a plethora of applications; nevertheless, its
production from waste/residues is often overlooked. Gasification and subsequent conversion of
the raw synthesis gas to hydrogen are an attractive alternative to produce renewable hydrogen. In
this paper, recent developments in R&D on waste gasification (municipal solid waste, tires, plastic
waste) are summarised, and an overview about suitable gasification processes is given. A literature
survey indicated that a broad span of hydrogen relates to productivity depending on the feedstock,
ranging from 15 to 300 g H2/kg of feedstock. Suitable gas treatment (upgrading and separation) is
also covered, presenting both direct and indirect (chemical looping) concepts. Hydrogen production
via gasification offers a high productivity potential. However, regulations, like frame conditions or
subsidies, are necessary to bring the technology into the market
