The purpose of the article is to assess the agricultural biomass hydrogen production potential and determine the areas of technical support for the realization of this potential. The article presents a promising model of production and biofuels use of agricultural origin. According to this model, it is appropriate to produce diesel biofuel, bioethanol (in the amount necessary to ensure the mobile equipment operation), biogas, biohydrogen, generator gas, solid biofuels (rolls, fuel pellets, straw briquettes). It is established that hydrogen production in agriculture is possible using both the method of biomass thermochemical conversion and the biomass fermentation method. When using the thermochemical method, the proportion of plant biomass is used for the production of fuel pellets. Generator gas is produced of granules. Generator gas is used to produce biohydrogen. Additionally, the biomass of plant origin proportion, as well as livestock by-products can be processed into biogas by dark fermentation. For the biohydrogen by thermochemical method production, the use of advanced gas generators is proposed, the design of which prevents the formation of solid deposits on the working surfaces in the gas formation chamber. For the biohydrogen by fermentation production, the use of rotating bioreactors is proposed. It is established that the theoretical potential of hydrogen production of plant origin agricultural biomass by thermochemical transformation is about 4.8 billion m3 of hydrogen per year. The theoretical potential of hydrogen production by fermentation is about 1.4 billion m3 per year. For the hydrogen theoretical potential practical implementation, further theoretical and experimental studies of both methods of obtaining hydrogen in the conditions of agricultural production are necessary.
