Abstract

This paper explores the potential of biomass gasification as a key technology for producing green hydrogen in the era of renewable energy transition. Biomass gasification offers a sustainable pathway to convert organic materials into synthesis gas (syngas), which can then be processed to produce hydrogen through water-gas shift reactions. The utilization of biomass feedstocks for hydrogen production provides a renewable and carbon-neutral alternative to fossil fuels, offering significant environmental benefits by reducing greenhouse gas emissions and reliance on finite resources. This review examines the principles of biomass gasification, including process configurations, feedstock options, and technological advancements. Additionally, it discusses the challenges and opportunities associated with biomass gasification for hydrogen production, including feedstock availability, process efficiency, and integration with renewable energy systems. By leveraging biomass gasification technology, the green hydrogen sector can contribute to decarbonizing various sectors such as transportation, industry, and energy storage, facilitating the transition towards a sustainable and low-carbon future.
