The article proves that today Ukraine finds itself in a situation where it depends solely on imported supplies of light oil products to meet its motor fuel needs, which is unacceptable from the point of view of the country’s energy and national security, and the solution to this problem lies in the plane of organization of motor fuel production from the country’s own natural resources. The purpose of the study is to substantiate the technical and economic foundations for creating a synthetic motor fuel subsector in Ukraine. To achieve this aim, the authors define the classification of alternative motor fuels; provide a comparative description of the energy content and scope of use of different types of motor fuels, and also provides comparative characteristics of synthetic along with the best grades of natural oil; assess the compliance of synthetic gasoline and diesel fuel with the Euro-4 standard; considers the technical-operational advantages of synthetic analogues of oil fuel over other alternatives. Based on the carried out analysis, the article proves that, given the limited resource capabilities of Ukraine’s motor fuel production from oil and natural gas, the production of synthetic liquid motor fuel (SLMF) from coal raw materials should be recommended for development in the country; the raw material base for the production of synthetic liquid fuel is researched. The article also analyzes the peculiarities of methods and specific technologies for producing synthetic liquid motor fuel from coal and determines that the technology of synthesizing synthetic liquid motor fuel using the Fischer-Tropsch method with preliminary production of synthesis gas by steam-oxygen gasification of coal is advisable for development in Ukraine. Taking this into account, the resource and product balance of the full cycle of synthetic liquid fuel production is formed, a general production scheme of the industry subsector of SLF in Ukraine is developed, technical-economic characteristics of the national and regional industrial complexes for the production of SLF are presented, and the structure of the subsector for the production of SLF in the country is proposed.

The purpose of the article is to study the European experience of the functioning of heat energy markets, identify the components of their deregulation, and develop proposals for the formation of regional heat markets in Ukraine. The article stipulates that currently there is no trans-European legislation on the formation of heat energy markets, there are only certain provisions that relate to its production, consumption and accounting. From a theoretical point of view, there are three types of competition in the heat energy markets: between heat supply sources; between producers of centralized heat; between companies for assets. The analyzed experience in the development of heat energy markets in three European countries testifies to the fundamental differences in its structure. Denmark’s heat energy markets are government-regulated, where there is a partial distinction between the functions of production, transportation, and distribution of heat; pricing is carried out on a regulatory basis of non-profit; there are no transparent conditions for access to the network, and the consumer has limited opportunities to disconnect from the system. In Sweden, competition is open at the wholesale level between heat producers; the functions of production and supply are demarcated, and the distribution and supply functions are combined; the retail heat market is self-regulating, which implies the need to coordinate heat prices between suppliers and consumers who, in case of disagreement, have the opportunity to refuse centralized heat supply. Lithuanian heat energy markets are open to wholesale competition and operate in the forward segment, while at the retail level they are regulated, where the transmission from production and supply has been unbundled; regulatory access to heating networks for independent producers has been introduced, and consumers have the right to refuse centralized heat supply. The highlighted features allowed to provide proposals for the formation of heat energy markets in Ukraine, including: the development of competition between heat producers; delimitation of the functions of production, transmission and distribution; formation of its forward, spot and balancing segments; introduction of auctions with the declared pricing method under the pressure of regulatory price restrictions, which are established on the basis of business standards according to the benchmarking system.

The purpose of the article is to analyze individual measures for the thermal modernization of buildings and determine the sequence of the implementation of such measures, allowing to obtain results in the shortest possible time with the maximum possible result. The actual state of the housing stock of Ukrainian settlements in the pre-war period did not meet the EU requirements for energy efficiency. After massive damage to residential buildings as result of russian aggression, their restoration becomes an urgent task. The article proposes to restore the settlements of Ukraine that suffered from the armed russian aggression by performing repair work with simultaneous thermal modernization of residential buildings. The content of the concepts of «traditional and deep thermal modernization of residential buildings» is examined and it is proposed to focus on traditional modernization, which involves a set of works on replacing windows and doors with energy-efficient ones, insulation of enclosing building structures (facades, basement, roof and basement floors), thermal modernization of engineering heating systems and hot heat supply (thermal insulation of intra-house pipelines, installation of individual heat points, balancing of heating systems, installation of apartment thermostats), as well as installation of individual ventilation devices with the possibility of heat recovery. On a conditional example, two options for performing works on mass thermal modernization in conditions of scarcity of investment resources are considered: the first is the implementation of works on thermal modernization of individual houses «turnkey»; the second is the implementation in all houses of only those measures that have the shortest payback periods and the implementation of which provides the best energy savings. A computing with use of a conditional example showed that the second option allows saving energy resources by 35% more than in the first option. According to the results of the study, the following sequence of thermal modernization works is proposed: priority measures (replacement of windows and doors), modernization of engineering heating systems, installation of individual ventilation systems, insulation of enclosing structures.

The purpose of the article is to substantiate the feasibility of an integrated approach to the implementation of measures for the restoration and modernization of housing stock and heat supply objects. On the conditional example of heat supply of a heated quarter (which means a small number of residential buildings to be heated, a local boiler room and local distribution heat networks), various modernization options are considered: separate thermal modernization of buildings, modernization of heating networks, modernization of the boiler room, and options for simultaneous modernization of all elements of the chain: production-supply-consumption of heat energy (complex modernization of the heated district). It is proved that precisely a comprehensive modernization, which involves a simultaneous production, coordinated in terms of time and volumes, supply and consumption of heat, is an effective instrument for improving efficiency in the sphere of heat supply and heat consumption. The complexity of modernization in this example involves thermal modernization of buildings in the heated district (with a decrease in heat consumption by 40%) with the simultaneous modernization of heat transmission networks (with a decrease in heat loss when supplied from 20% to 5%) and modernization of the boiler room (with an increase in the efficiency quotient of boiler equipment from 88% to 93%). The implementation of such a project is economically feasible for all participants: consumers reduce the cost of paying for heat supply services by 49%, and the supplier and producer of heat with a slight (up to 6%) increase in heating tariffs provide break-even activities and receive a larger investment resource in the form of a larger amount of depreciation. At the national level, the proposed mass complex modernization of heated districts can almost halve the consumption of natural gas by municipal heat and power engineering and to the same extent reduce emissions of harmful substances into the atmosphere. In addition, it becomes possible to significantly reduce the amount of subsidies from the budget for the payment of housing and communal services by the population.
