The disadvantage of generating electricity from renewable sources is the need for its simultaneous consumption afterwards or distribution to other consumers over long distances, which is accompanied by significant energy losses in networks with increasing transportation distances. In addition, there is a discrepancy between the seasonal maximum volumes of electricity generation and consumption. Thus, imbalances arise between the demand and supply of electricity on the market. This problem can be solved by converti...

This paper analyses the current development status of hydrogen production technologies and projects global demand growth through 2050. Production costs and CO2 emissions per kilogram of hydrogen are identified as key factors influencing the adoption of hydrogen technologies. While fossil-based methods currently offer cost advantages, electrolysis and biological processes demonstrate superior performance regarding CO2 emissions. Provided that sufficient investments are made, the cost of renewable energy production ...

The study is based on an assessment of the level of land disturbance by full-scale military operations and the emergence of land use deficits in certain territories. It has been determined that military operations cause disturbance of the earth's surface in the form of mechanical, physical and chemical changes in the soil, the negative consequences of which can be felt for decades. Territories that have been subjected to military operations become dangerous for the population for a long time and unattractive for i...

In light of the pressing need to achieve climate neutrality in the energy sector, the European Union seeks to identify strategies that will enhance and diversify its green energy supplies. As a renewable energy source, green hydrogen promises to offer a viable alternative to fossil fuels where green electricity may be insufficient or inaccessible. This is why the production and supply of this innovative energy carrier is becoming a significant focus in EU politics and research. This article examines and compares p...
