In modern petrochemistry, in the conditions of increasing energy shortage and significant increase in demand for all types of fuel raw materials, saving energy resources and raw materials is an extremely urgent problem. Biodiesel is an alternative fuel used in diesel engines, made from renewable raw materials such as vegetable oils. The article discusses the process of obtaining biodiesel from grape seed oil, a waste remaining after the production of various wines and fruit juices, at Ganja Sharab-2 OJSC, an agro-industrial enterprise operating in the Western region of Azerbaijan. Oil obtained by extraction from grape seed waste was used as raw material. Biodiesel was produced from grape seed oil by transesterification using KOH as a catalyst, the reaction temperature range is 20˚C, 40˚C, 60˚C and the ratio of oil to methanol is 1:3, 1:6, 1:12 mol. When the transesterification reaction was carried out optimally at a molar ratio of oil to methanol of 1:12 and a temperature of 60˚C, the biodiesel yield increased from 60% to 100%. The composition of the resulting biodiesel was analyzed by IR spectroscopy and confirmed by peaks indicating that it was formed as a result of transesterification of vegetable oils. Various physicochemical properties of biodiesel fuel were studied in comparison with the properties of petroleum-based diesel fuel. The resulting biofuel surpasses traditional diesel fuel in both its physicochemical properties and environmental and performance characteristics. To improve the operational and environmental properties of diesel fuel, it is proposed to use biodiesel as a biological additive.

In recent years, almost all countries in the world have been increasing the generation of thermal and electric energy using renewable energy technologies. This is due to the rising cost or depletion of traditional energy sources, the need for reliable and efficient energy supply to remote, hard-to-reach and isolated regions. Hydrogen fuel can become an alternative to traditional energy sources, so it is attracting increasing attention as a fuel. The production of hydrogen fuel using electricity generated by renewable energy sources has the lowest harmful emissions, so it is becoming the most widespread. This study considers the prospects for producing «green» hydrogen in the Arctic zone. The Murmansk region uses outdated boiler equipment for heat supply, running on low-quality fuel – fuel oil. Hydrogen can partially replace traditional fuel in the form of fuel oil, if we take into account the transportation of fuel oil to the boiler house, the cost of hydrogen will be competitive. Schemes for producing hydrogen are proposed: near the source of electricity and on the site of an industrial enterprise. The study shows a promising scheme for burning hydrogen in existing hot water boilers.

Hydrogen is an effective energy carrier for thermal power technologies and electrochemical sources of electric current. The proposed technology eliminates the need for storing and transporting hydrogen and ensures its production in the volume required for direct use at power plants. This paper considers the possibility of using alkali metals as the most effective method for producing hydrogen by reaction with water. The reaction product (alkali) is repeatedly reduced to pure metal by electrolysis using energy (during the nighttime dip in energy consumption at thermal power plants and nuclear power plants) or using renewable energy during its natural availability (hydroelectric power plants, solar power plants, wind power plants). Calculation studies have shown that the process of water reduction by alkali metals is exothermic, with the release of heat of high thermodynamic potential, which allows, along with the direct conversion of hydrogen into electrical energy using fuel cells, to carry out additional production of electrical energy based on the thermodynamic Rankine or Brayton cycles.

 The increasing population and socio-economic development of Uzbekistan have led to a rise in production volumes, as well as shifts in consumption patterns and lifestyle. These changes have significantly contributed to the growing overall waste volume, with an increase in waste generation per capita. At the same time, there are opportunities to improve waste management strategies, implement recycling methods, and reduce the total volume of generated waste. These opportunities highlight the need for more sustainable waste management practices that align with the country’s evolving socio-economic landscape and environmental goals.
This research focuses on the challenges posed by waste management in Uzbekistan and explores the potential solutions that can enhance the effectiveness of waste reduction and recycling processes in the country. 

The paper discusses the importance of purifying chemical liquids, particularly monomers, to improve the quality of final products. Impurities in raw materials complicate technological processes, increasing costs and degrading product properties. A new purification method is presented, which uses strong electric fields and discharges to remove impurities. The experiment was conducted on hexene-1, where adsorbents and electrical discharges were employed to enhance purity. Optimal process conditions were identified, such as electrode voltage, linear flow rate, and temperature. Maximum purification efficiency was achieved using silica-based gels due to their microporous structure, which facilitates the penetration of oxygen-containing molecules into the pores of silica gel. The results showed that the purification efficiency is higher when using a weak inhomogeneous electric field, as this is associated with higher field intensity and greater average current. Changes in the composition of hexene-1 before and after purification were detected using infrared spectroscopy. After purification with silica gel, the absorption band corresponding to carbonyl compounds disappeared. The study confirms the high efficiency of the barrier discharge method for purifying hexene-1 and emphasizes the importance of selecting the right adsorbent to optimize the purification process. This method can also be applied to purify other chemical liquids.

Energy systems based on traditional centralized architecture have reached the limit of their efficiency. They are not able to meet modern requirements of the global energy sector: changing qualitative characteristics of demand for electricity, variable nature of demand and supply of electricity, environmental requirements. A solution to the problem of low efficiency of centralized systems is the transition to the concept of distributed energy, in particular, to the emergence of the concept of the Internet of Energy. The Internet of Energy is a set of technologies and business models that ensure operational interaction between energy market participants in the context of decentralized intelligent control of the energy system. One of the features of the Internet of Energy concept is that, in addition to renewable energy sources, which play a key role in energy production, hydrogen can be used to store and transport energy. It can be used to store excess energy, and then distributed across networks for use during periods of greatest load on the system. The article provides an analysis of the Internet of Energy concept: structural elements of the Internet of Energy system, the main components of the architecture, the connections that exist between them and ensure the successful functioning of the system. Also considered are projects for the implementation of decentralized energy systems based on the architectural model of the Internet of Energy, created in Russia, the USA, and Singapore: problems of these projects and prospects for their development.
