Geopolitical transformations produce their impact on the cross-border regulation of hydrogen production and transportation. Russia's military aggression has blown up the global energy system and driven up energy prices. This exacerbated the issue of energy security, highlighting the excessive dependence of the EU on imports from the Russian Federation. These factors have accelerated Europe's transition to clean energy and increased hydrogen production. The object of the research is legal relations in the field of development, transportation and storage of hydrogen in the territory of European states. The results made it possible to propose mechanisms for reforming the legal regulation of the production and transportation of hydrogen across Europe. The vectors of the regulatory policy of European states are revealed, which should coordinate the increase in the potential of Ukraine in the regional leadership in decarbonization. It was stated that the legislative innovations of Ukraine are the basis for adaptation to EU practices. The practical approbation of the changes in production practice declared by the states of Europe in the context of the global energy transition to a carbon-neutral society is substantiated. It has been established that reducing the cost of hydrogen and finding its wide application will become a global priority in the short term. The basis of the hydrogen infrastructure has already been laid by including it in the renewed trans-European energy network. The issue of full-fledged approbation of production procedures in modern geopolitical conditions is debatable. Despite the hostilities, Ukraine continues the course of reforms by coordinating and arranging the purchase of hydrogen from renewable sources, which will allow full accession to the EU Energy Platform. The results of the study can be used in the legislative sphere for a comprehensive reform of the national legislation of Ukraine

The changes that have affected all spheres of society have also affected the existing stereotypes of gender behaviour, so the issue of the place and role of men and women in society focuses on research on the aspirations, interests and preferences of both sexes. Gender issues are studied in an interdisciplinary aspect, so recently there have been many studies in which the subject of discussion concerns different fields of science - psychology, philosophy, linguistics, journalism, sociology, political science and many others. To study the gender sphere of concept of contemporary periodicals for women and men, the following scientific methods are considered: descriptive method, analysis, content analysis, questionnaire, comparative method and induction. However, an attempt has been made to analyze different approaches to the study of concepts (in particular, gender). There are many different definitions of the concept, which indicates the complexity and ambiguity of the “concept” meaning, but there is a limit to the scientific description and understanding of the concept. The gender sphere of concept is a system of interactions of maximum concepts of man and woman, as well as their derivatives, which are called gender and social roles in society performed by man and woman. Concepts, sphere of concept include gender features, which allow a gender approach to study the gender sphere of concept of contemporary periodicals for women and men. The study of the gender sphere of concept within the framework of contemporary gender-labelled publications allows to identify and correlate metagender and gender concepts that appear in society.
