“…A number of authors have considered the problems of the CIS countries (including Russia) in the field of decarbonization, considering renewable energy as a key tool for reducing greenhouse gas emissions [41]. In addition, the development of renewable energy is considered as a factor in the conservation of forests [42], which is relevant for remote regions of Eastern Siberia and Transbaikalia, where timber is used as fuel by farmers and households, an alternative to which is the use of solar and wind energy [43]. At the same time, not enough attention is paid to the differences in energy supply of the territories of Russia, combining clusters of thermal, hydro-, and nuclear power, with which renewable energy will compete in the national market, and the psychological perception of which by the population is also ambiguous.…”

This article presents a study of the specific features and development factors of renewable energy in macro-regions that combine extractive and industrial clusters with rural, sparsely populated areas. While in some countries—leaders in energy transition (the EU, China)—the growth of investments in solar, wind, and hydropower production is taking place systematically within the framework of an increasing number of national and international strategies and programs, in the Russian Federation there is a lack of renewable generation capacity. Particular difficulties are experienced in regions that, on the one hand, have a developed fuel and raw material complex and, therefore, fuel generation (which makes a significant contribution to global greenhouse gas emissions), and, on the other hand, many rural, sparsely populated areas that are in need of new distributed generation. The aim of the study is to analyze the factors of transition to renewable energy in mineral-resource regions, such as the Siberian Federal District (Siberia), as well as to identify measures to enhance their effectivity. The article shows the place of Siberia in the national energy system and considers the factors related to its energy transition in detail, e.g., the saturation with main powerlines, the control of air pollution caused by fuel energy facilities, its provision with fuel resources, investments in renewable energy, and ways of improving the health and well-being of the local population. Attention is drawn to the challenges and obstacles related to the development of renewable energy in the Siberian Federal District, associated, on the one hand, with Russia’s lagging behind other countries in the dynamics of energy transition, and on the other hand, with external and internal technological and investment restrictions.

“…The cost reduction attributed to CSP-biomass hybridization stems from the shared use of infrastructure and common equipment [10]. In addition to the aforementioned production cost reduction, hybridization contributes to improving the dispatchability of electricity generation compared to conventional CSP plants, which are more or less subject to the randomness of solar resources [11,12]. Furthermore, other additional advantages derived from CSP-biomass hybridization include improved thermal cycle efficiency and reduced environmental impact due to the smaller solar field size and lower water consumption [13].…”

The current context of the climate emergency highlights the need for the decarbonization of the energy sector by replacing current fossil fuels with renewable energy sources. In this regard, concentrating solar power (CSP) technology represents a commercially proven alternative. However, these types of plants are associated with high production costs and difficulties in controlling production during temporary variations in solar resource availability. In order to minimize these drawbacks, this study proposes the hybridization of CSP technology with direct biomass combustion, with the particularity of an innovative process scheme that does not correspond to traditional series or parallel configurations. This paper focuses on the techno-economic evaluation of this novel configuration in a small-scale power plant. To achieve this, both solar resource and biomass production, which are dependent on the selected location, were analyzed. Additionally, the plant was characterized from both technical and economic perspectives. The obtained results allowed for the characterization of the Levelized Cost of Energy (LCOE) based on various parameters such as the size of the solar field and biomass boilers, as well as limitations on biomass consumption.

“…asification of biomass allows the production of heat and power using different kinds of cycles and engines (internal and external combustion engines, fuel cells and even gas turbines), predominantly at small-capacity power plants. 1,2 The drawbacks of biomass gasification technologies are low availability and low efficiency of biomass conversion. One of the common problems is tar pollution of the producer gas.…”

The article concerns some problems associated with the use of low‐grade fuels for the production of syngas in fixed‐bed gasifiers. Syngas is typically used to feed internal combustion engines in small power systems. Gas quality can be understood as its various characteristics, such as calorific value, the content of individual components (for example, hydrogen), low tar and soot content, and so forth. Achieving these quality criteria often requires specific conditions for the gasification process, in addition, some of them may be limited by additional requirements that are associated with thermal stability or fuel conversion requirements. When evaluating the technical and economic characteristics of gasification‐based power plants, the optimal efficiency does not always correspond to the higher efficiency of the gasification process and the quality of producer gas. In this regard, the aim is to develop optimization methods for different criteria and to create regime maps that cover physically achievable options. Novel mathematical models of tar conversion are proposed, allowing investigation of the dependencies of tar yield on gasification conditions, including the addition of catalysts or staged air supply. Computational tools based on thermodynamic and kinetic models make it possible to solve some of these problems, first of all, to consider and compare the efficiency of various methods for reducing tar content in producer gas (staged gasification, fuel mixing, thermal, and catalytic methods of tar elimination). The choice of relatively simple mathematical models allows us to conduct numerical calculations in a wide range of conditions and to optimize the parameters of biofuel conversion plants. This approach allows a more flexible choice of gasifier operating conditions, including its work as a part of a power unit. Optimal parameters are calculated for specific conditions: secondary air ratio (1–20%) and fraction of catalytic material (5–10%). The results may be used in the analysis and choice of biofuel gasification conditions at small power plants.
