Abstract
Abstract Biohydrogen production in agricultural enterprises is an urgent matter. It is appropriate to utilize two methods of biohydrogen production: a thermochemical method – from crop-based biomass and anaerobic digestion (fermentation) method – from animal-based biomass.. It is appropriate to use gasifiers for the thermochemical method and biore-actors for fermentation method. The theoretical potential of biohydrogen was established with due regard to the amount of biomass which is necessary for utilization in livestock agriculture, for fields fertilization as well as with the consideration of the coefficients of concordance with hydrogen equivalent and loss factor under biohydrogen production. The theoretical potential of biohydrogen from crop-based biomass in Ukraine amounts to 77 billion m3, during the period of three years (on average 25.6 billion m3 per year).
Highlights
Agricultural production mainly focuses on providing the population with foodstuffs (Golub et al, 2017)
Agricultural production can effectively arrange for production of biofuel from biomass, in particular biogas, diesel biofuel, bioethanol, baled straw, fuel pellets, briquettes and generator gas (Kukharets, 2016; Rzeznik and Mielcarek, 2018; Ovcharuk et al, 2020)
Such a production has become traditional, though the production of renewable energy from biomass causes some fear in researchers as to reduction of the level of core product production – foodstuffs, as well as to reduction ofthe amount of plant food in

Tkach soil caused by the use of some cultivated areas for growing bioenergy crops and by the use of straw as fuel (Verdade et al, 2015; Gomiero, 2018; Tryhuba et al, 2021a, Tryhuba et al, 2021b)
