This article analyzes the prospects of integrating renewable energy sources into Russia’s power systems, which are facing the depletion of traditional generation resources. Using the Krasnokamensk CHP plant – critical for the Zabaykalsky Krai – as a case study, the paper explores a hybrid solution involving wind power installations to offset coal shortages. The study evaluates the techno-economic aspects of this approach, including the use of the Weibull distribution function to accurately assess the wind energy potential of the region. It is demonstrated that a synergy between wind power and CHP is the optimal strategy for extending the operational life of the plant, diversifying the fuel mix, and achieving sustainable development goals.

The article considers the possibility of energy supply of the port cities Sovetskaya Gavan in Khabarovsk Krai and Nakhodka in Primorsky Krai using wind power plants (WPP). The wind potential of the regions has been analyzed, promising sites for wind power plants (WPP) have been identified, and their expected output has been calculated. The technical and economic aspects of the projects have been studied. It is shown that the introduction of wind power plants and energy storage systems (ESS) can reduce the dependence of the regional economy on traditional energy sources, reduce greenhouse gas emissions and ensure sustainable energy supply. Recommendations on project implementation are given, taking into account climatic peculiarities and infrastructural limitations.

The article discusses the process of methanol production from hydrogen (H2) and carbon dioxide (СО₂) as a promising direction in the field of gas chemistry. Methanol, which is the most common inhibitor of the formation of gas hydrates, can be synthesized from CO₂. The paper describes in detail the main stages of the process, discusses modern technological solutions such as the use of «green» hydrogen, and shows the economic and environmental aspects of production.

Today, due to the reorientation of the foreign economic activity of the Russian Federation to the countries of the East and the Asia-Pacific region, the Far East is one of the fastest growing regions. The growth of the region’s economy is closely linked to an increase in energy consumption. In the conditions of moral and physical deterioration of the generating equipment of the Far East, the question of ways to increase the efficiency of coal-fired power plants in the region is acute.
