Hydrogen plays a key role in achieving carbon neutrality, particularly in the transport and industrial sectors, where reducing dependence on fossil fuels is a major challenge. This review examines recent systems for producing green hydrogen from biomass, analysing various energy architectures such as electricity–hydrogen cogeneration, multigeneration, polygeneration and hybrid configurations. The systems studied are based on the conversion of biomass via gasification, combustion or other thermal processes, coupled with electricity generation cycles (SRC, ORC, etc.) to power electrolysers. This review describes the operating principles of these systems and the interactions between their components, and compares the architectures according to their hydrogen production performance in order to identify the most promising approaches for sustainable production from biomass.
