Advances in biomass-based thermochemical hydrogen production technology

Abstract

The excessive utilization of fossil fuels has caused the energy crisis and greenhouse effect, and the development of clean and sustainable sources can adjust the energy structure of China and promote green and sustainable development. Hydrogen, as a promising energy source and a clean fuel with no harm to the environment, has become the most promising energy carrier in future energy. Therefore, it is necessary to seek green and sustainable hydrogen production technologies with low energy consumption and low cost. Under the background of "double carbon" , hydrogen production from biomass is considered as a green and sustainable development technology, which is deemed to have long-term growth potential and is expected to gradually reduce environmental pollution and over-exploitation of resources. In view of the current research trends and emerging technologies, this paper focuses on the review of the principles, influencing factors and current research status of hydrogen production technologies from thermochemical conversion of biomass to pyrolysis, steam gasification, supercritical water gasification and chemical looping hydrogen production, and provides an outlook on the future development of current technologies.
