Rational development and utilization of hydrogen energy can promote the transformation and upgrading of Chinese energy structure

as well as the sustainable development of society. To achieve the carbon peak and neutrality targets

biomass hydrogen production technology is considered as a green hydrogen production technology with great development potential. The technology can be divided into thermochemical hydrogen production technology and biological hydrogen production technology. The principles

influencing factors

advantages and disadvantages and research status of hydrogen production technologies involving steam gasification

supercritical water gasification

biomass pyrolysis reforming

light fermentation and dark fermentation are reviewed in this paper. Moreover

the technical barriers and future development obstacles of various hydrogen production technologies are comprehensively analyzed. The research has certain guiding significance for the development of biomass hydrogen production technology.
