CONCEPT OF BIOHYDROGEN PRODUCTION BY AGRICULTURAL ENTERPRISES

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 di-gestion (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 re-gard to the amount of biomass which is necessary for utilization in livestock agriculture, for fields fertilization as well as with the conside-ration 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).
