Hydrogen is an energy carrier, analogous in many ways to electricity, but with the potential for more advantageous applications in some situations, especially in industry and transportation. Hydrogen can be used in various devices, including hydrogen engines and fuel cells. Hydrogen does not occur naturally in large quantities or in high concentrations on our planet. Rather, it must be produced from other compounds, and finding the most advantageous ways to produce hydrogen remains a significant challenge. One important option is hydrogen production from biomass, and that is the focus here. Due to the importance of this area, a special issue of Biofuels was devoted to Hydrogen Production from Biomass in order to discuss recent advances in the area. The special issue contains 11 papers on various topics related to hydrogen production from biomass. The special issue presents information on methods for the production of hydrogen and hydrogen-related fuels from biomass, ways of assessing such processes and uses of hydrogen produced from biomass. As Guest Editor of this special issue of Biofuels on Hydrogen Production from Biomass, my aim was for it to help increase the potential benefits realizable from both hydrogen and biofuels for society and industry, and to provide input to researchers related to hydrogen energy and its linkages with biofuels, biomass and bioenergy. The current contributions of biomass to hydrogen production is small relative to that from other sources. But the demand for economic and clean hydrogen is expected to increase in the future. Then, the contributions of biomass to hydrogen production are expected to increase, and this is anticipated by many to be aligned with such developments as
