Hydrogen production from biomass is sustainable and green. The conventional process for producing hydrogen from raw biogas involves a steam reformer, two temperature-staged water–gas shift reactors, and a pressure swing adsorption (PSA) unit for hydrogen separation. This work performed a techno-economic assessment of this process. The system modeling was performed in Aspen Plus and Aspen Plus Adsorption for the PSA unit. This is one of the first studies on hydrogen produced from raw biogas without an upstream upgrading system, so it required a complete design of the PSA and vacuum pressure swing adsorption (VPSA) systems according to different gas compositions.
