In the Republic of Sakha (Yakutia), as of January 1, 2021, there are 297 hard-toreach settlements with a population of 542.5 thousand people. All the necessary life support elements are delivered only in the cold months, when the winter road opens. But even in this season, transportation is carried out in insufficient volume, especially the lack of motor fuel should be noted. Part of this problem can be solved by introducing biogas technology. The production and use of biogas can become a significant contribution to the widespread organization of small summer farms. It will increase the volume of milk yields, as well as provide an opportunity to create new jobs in rural areas (logistics, engineering services, construction of buildings and structures). The theoretical studies carried out made it possible to outline ways to solve the stated industry problem by developing new technological solutions that allow the development of decentralized lands. The currently existing foreign and Russian biogas technologies exclude the possibility of their application in the natural and climatic conditions of production in the agricultural sector of Yakutia, since they are designed for large livestock farms, have a significant price and operate in mesophilic mode, that is, they require connection to the central electric grid. The main criterion for using biogas as a fuel is the possibility of creating a non-volatile autonomous production. Biogas is used as an alternative fuel in indoor heating systems, as motor fuel in internal combustion engines. It is converted into electricity and used in cooking. Yakut scientists, due to the cold climate of the region, investigated and tested the anaerobic process in the psychrophilic mode of the installations. At the same time, dynamic and mathematical models of the anaerobic process in the psychrophilic mode of operation of biogas plants were developed for the first time.
