Purpose of the study is to assess the current and prospective energy potential of agribiomass (agricultural residues and energy crops) in Ukraine, to determine its main components and the most effective areas of their use. Methods. The assessment of the current potential of agribiomass is performed using official statistics on crop production in Ukraine. Based on these data, the total amount of crop residues formed and their share available for energy needs is determined. When assessing the potential of energy crops, it is assumed that they are grown on 2 million hectares of unused agricultural land, the total area of which is up to 4 million hectares in Ukraine. The study of the prospective potential of biomass is performed for 2050, based on key growth factors, such as increasing yield of crops, especially cereals; doubling the area under energy crops and increasing their yields, etc. Results of the assessment show that according to 2018 data, the total bioenergy potential in Ukraine is more than 23 Mtoe (the economic potential). Its largest components are agricultural residues (44%) and energy crops (32%). Expert estimates suggest that by 2050, the biomass potential could increase to more than 47.5 Mtoe/yr, in other words almost to double. Forecasting the structure and directions of use of biomass potential by 2050 shows that about 20 Mtoe of biomass/biofuels of the following types will be consumed for energy: wood biomass, primary and secondary agricultural residues, energy crops, biogas/biomethane from different types of raw materials, liquid biofuels (biodiesel, bioethanol). Conclusions. Areas of use of biomass/biofuels include the production of heat and electricity from solid biofuels, obtaining of biogas and biomethane, as well as the production of motor biofuels (biomethane, biodiesel, bioethanol). In the near future, it is considered necessary to develop a long-term strategy for the development of bioenergy in Ukraine, taking into account results of the study. In turn, the basic figures of the bioenergy development strategy can be used for the elaboration of the updated Energy Strategy of Ukraine until 2050.
