“…There are works that consider the use of gravitational energy storage systems with the integration of renewable energy sources [16,17]. The authors of [18] analyzed the prospect of using of a gravitational energy storage system in existing shafts of hard coal mines in Poland. The authors found that the obtained economic effects of the solution were low, and therefore there was no economic justification for activities related to its implementation.…”

The daily non-uniform power demand is a serious problem in power industry. In addition, recent decades show a trend for the transition to renewable power sources, but their power output depends upon weather and daily conditions. These factors determine the urgency of energy accumulation technology research and development. The presence of a wide variety of energy storage mechanisms leads to the need for their classification and comparison as well as a consideration of possible options for their application in modern power units. This paper presents a comparative analysis of energy storage methods for energy systems and complexes. Recommendations are made on the choice of storage technologies for the modern energy industry. The change in the cost of supplied energy at power plants by integrating various energy storage systems is estimated and the technologies for their implementation are considered. It is revealed that in the large-scale power production industry, the most productive accumulation methods for energy systems and complexes are the following: pumped hydroelectric energy storage systems, thermal and thermochemical accumulations, and hydrogen systems. These methods have the best technical and economic characteristics. The resulting recommendations allow for the assessment of the economic and energy effect achieved by integration of storage systems at the stage of designing new power units.

“…With regard to medium-sized and large industrial enterprises, integration into the European energy system has provoked increased demands for non-alternative green generation from alternative energy sources. Moreover, there is even a lot of research conducted on greener energy solutions for companies based on conventional sources of energy, for example: (Kulpa et al 2021;Dyczko et al 2021;Stecuła and Brodny 2018;Stecuła 2018). The effective integration of energy facilities into the energy markets of Ukraine is presented to ensure the stabilization of network operating parameters as well as allowing the saving and utilization of industrial waste in Ukrainian enterprises and stabilizing tariffs for the entire range of energy-consumption stakeholders.…”

This article is devoted to an analytical review of the situation in the energy sector of Ukraine, taking into account constructive changes in the connection of the Ukrainian energy system to ENTSO-E and the destructive situation caused by industrial infrastructure failures and economic renewal. It focuses on Ukraine in the context of the principles of decentralization in the direction of significantly increasing the net cost of microgeneration, decarbonization and the transition to "green" energy. The national resource potential of energy-efficient and energy-saving technologies is systematized and the applied recommendations are provided to support state and local trends in energy sector development, namely energy storage projects, distributed generation and microgeneration based on Net Energy Metering to support small projects that solve energy problems. Included are institutional proposals for the establishment of the Agency for Decarbonization in Ukraine for the "green" transition, with broad powers of communication and the ability to make decisions on reducing carbon emissions in all areas. The possibility and expediency of using the concept of innovation is considered both from the global point of view of Ukrainian industry (with the potential prospect of using Ukraine's industrial and logistics infrastructure as a mega-industrial park for the EU) and in the local sense of national energy, including improvements to the EU's energy balance. It has been proven that the use of the nearshoring mechanism in Ukrainian industry in general, and in the energy sector in particular, can improve Europe's energy balance, which has deteriorated over the past five years. Thus, the negative trend of the EU energy balance in thousands of tons of oil equivalent and in percentage terms was demonstrated. To improve the situation, the forecast of energy prices for individual EU countries was calculated taking into account Ukraine's integration into the European energy system. The analysis and calculations revealed a potentially possible level of price reductions in some EU countries up to 20%. Recommendations are for improving energy-management efficiency at the regional level in particular, ensuring transparency in the development of renewable energy sources, using significant national potential of biofuels and increasing natural gas production, developing a business model of gas distribution center in Western Ukraine, which will be part of national gas distribution system and the European energy market.

This paper considers a thermal accumulator using phase transition materials as a way to increase the energy efficiency and maneuverability of nuclear power plants. A low-power nuclear power plant is the object of this study. Such nuclear power plants have a great potential for widespread implementation as sources of thermal and electrical energy for facilities of mineral and raw material as well as fuel and energy complexes located in distant regions. The main principles of development of low-power nuclear power plants are revealed. So, in the development of low-power nuclear power plants, experience in the creation and operation of shipboard nuclear power installations is widely used. The problems of NPP operation in daily maneuvering modes within an isolated power system are revealed. A method for improving the energy efficiency and maneuverability of nuclear power plants is proposed, in particular, through the use of thermal accumulators with a phase change material directly in the NPP circuit. A method of assessment of the dimensions of the heat accumulator and the amount of heat accumulating material is presented. A method of assessment of the efficiency of the accumulator application scheme is presented. The thermal scheme of a promising low-power nuclear power plant with an RITM-200 reactor is compiled. A scheme for switching on a heat accumulator with a phase change material to a scheme for regenerative heating of a turbine is proposed. The heat storage material selection is made, the main elements and characteristics of such an accumulator are determined, and the parameters of the heat transfer fluid’s movement through the accumulator are determined. A mathematical model of the heat exchange in an accumulator based on the finite difference method is compiled, and the simulation results are presented. The results of the experimental verification of the model are presented. As a result of the calculation of NPPs’ thermal schemes in the standard version and the version with a heat accumulator, the power increase in the turbine plant due to the application of accumulated heat in the accumulator discharge mode is determined.
