“…Ukraine is expected to become a leader in hydrogen technologies at the EU level. According to the assumption by the energy association «Ukrainian Hydrogen Council», in 2050 Ukraine will have a reputation as a hydrogen hub in Europe, will rapidly expand the hydrogen market, in particular its export component [1]. In addition, according to the Timmermans Recovery Plan, the reconstruction of the energy sector in Ukraine will take place with an emphasis on its renewable energy sources.…”

The object of research is the process of using a hydrogen fuel cell to generate and accumulate electricity. The study highlights the feasibility of using a hydrogen fuel cell to provide electrical load. The potential of using hydrogen as an alternative energy source was evaluated. SWOT analysis was used as a research method, based on the results of which recommendations were developed. The proposed measures could be taken to increase the use of hydrogen energy as an alternative to traditional energy sources. The use of hydrogen technologies in an administrative building connected to an existing electrical network was analyzed. The economic and environmental aspects of the use of hydrogen fuel cells to meet the demand for electrical load were investigated. Six schemes of energy supply of the building and comparing them to select the optimal solution have been developed. In the study, the assessment tool was the Hybrid Optimization of Multiple Energy Resources (HOMER) software. The considered schemes were evaluated in accordance with a single generalized indicator. As a result, it was determined that the use of a hydrogen fuel cell could increase the efficiency of the traditional system by 85 %. For renewable energy systems, there was an increase in efficiency of 7 % (for the wind generator) and 10 % (for the photocell). The practical use of the results will contribute to the efficiency of the process of electricity production by equalizing the stability of energy supply in hybrid systems. The economic and environmental assessment conducted demonstrates the prospects of using a hydrogen fuel cell. This assessment is designed to strengthen consumer confidence in the use of hydrogen fuel cells and hydrogen in general

“…Вчені сходяться у думці, що для запобігання небезпечній зміні клімату недостатньо дій лише на рівні держави та бізнесу -необхідна участь людей та змін їх щоденних звичок. Для ефективного вирішення проблеми кліматичної кризи в розвинених країнах особистий вуглецевий слід необхідно скоротити на 80-90% до 2050 [1]. Кінцева мета країн ЄС є досягнення «кліматичної нейтральності», що передбачає скорочення викидів CO 2 в ЄС на 95% у порівнянні з рівнем 1990 р. Попит на природний газ в ЄС знизиться з ~ 5000 ТВт•год у 2020 р. до ~ 4000 ТВт•год у 2050 р. За даними МЕА, якщо додавати 20% водню у європейську газову мережу, то можна досягти скорочення викидів CO 2 на 60 млн.…”

The article shows that climate change is not only warming, but also extraordinary natural phenomena (droughts, floods, storms, tornadoes etc), which lead to significant economic damage. Climate warming is caused by increasing concentrations of greenhouse gases in the earth's atmosphere. The main task is to reduce carbon dioxide emissions. An analysis has been carried out of international documents such as the Kyoto Protocol, the Paris Climate Agreement, aimed at reducing greenhouse gas emissions into the atmosphere. It is shown that a significant amount of CO2 enters the atmosphere during the production of pig iron and steel, the data on the amount of carbon dioxide emissions from steel smelting in Ukraine and at «Azovsteel» iron and steel works have been provided. The article contains a critical analysis of the existing steel production technology, which is highly efficient but requires significant capital investment, fuel and energy resources, the source of which is the product of heat treatment of hard coal – coke, its carbon in the form of CO2 entering the atmosphere. Numerous proposed methods of steel production without the use of this coke are considered. One of the directions was the production of sponge iron without melting, another direction of coke-free metallurgy was high-temperature processes of obtaining liquid metal, that are carried out in one stage. The theoretically required amount of reducing agent at of iron with carbon monoxide and hydrogen has been determined. Methods of producing renewable gas by conversion of natural gas and gasification of coal are considered. The plans of the Metinvest Group management to develop a long-term technological strategy for metallurgical production taking into account environmental requirements are presented

This article explores the potential of green hydrogen for the development of the global hydrogen economy. The aim of the article is to investigate the essence of "green hydrogen" and the possibilities of its production and use in industrial sectors, which will enable the formation of a future global hydrogen economy independent of traditional fossil energy resources. The article discusses methods of green hydrogen production, its use in the transportation, industry, and energy sectors, as well as the benefits and challenges associated with the implementation of a hydrogen economy. Green hydrogen is produced by splitting water using renewable energy sources, making it an environmentally friendly fuel source. Research shows that green hydrogen can become an important component of the transition to low-carbon technologies, contributing to reducing carbon emissions, creating a sustainable and efficient energy system, and positively impacting the formation of climate neutrality. Emphasis is placed on the importance of developing and implementing hydrogen technologies in transportation, as this sector is considered one of the most harmful to the environment due to carbon emissions. Today, leading transport companies are developing prototypes and testing hydrogen vehicles in freight transport, railways, air and sea transport, as well as in automobile manufacturing. Infrastructure for the hydrogen economy is actively developing -plants for the production of clean hydrogen are being built, reservoirs for its storage and pipelines for transportation are being constructed. To support the development of the hydrogen economy at the national and international levels, a number of regulatory documents have been adopted, regulating the principles of low-carbon development and hydrogen transformation in all areas of public life. Thus, the research offers a new perspective on the hydrogen economy and opens up new opportunities for the development of sustainable energy based on green hydrogen.
