Purpose. Modelling environmentally safe bioenergy trends based on national and international pa-tent databases and scientific databases. Methods. Bibliometric method of analysis using the Scopus database and patent databases, model-ing methods using a special visualization software package. Results. An analytical diagram based on the review of patent databases was developed, as well as a model for visualization of interrelationships between clusters of bioenergy development trends as a com-plex solution for environmental protection. Thus, 4 clusters were formed based on data from the Scopus database using VOSviewer software: 1) cluster (red) reveals the environmental problems of changing the direction of implementation of stationary energy sources with the development of bioenergy potential, and the creation of strategies for this development at the level of regions; 2) cluster (yellow) covers the pro-cess of restoration of ecological systems, in particular forests and reduction of CO2 emissions from bioen-ergy; 3) cluster (green) covers the production and use of different types of fuel and energy produced by the introduction and improvement of bioenergy technologies; 4) cluster (blue) covers the impact of bioen-ergy technologies on environmental restoration and purification and reduction of damage from anthropo-genic impact. Conclusions. The analysis of patent databases with cluster visualization based on a bibliometric ap-proach allowed to identify the most promising areas of research in the field of bioenergy solutions devel-opment. Further research will be focused on the development of a lab bench for biogenic gas production with the possibility of complex processing of secondary raw materials and obtaining environmentally safe digestates.
