ENERGY DIPLOMACY IN THE QUADRANGLE OF ECONOMIC AND LEGAL RELATIONS

The research materials represent a theoretical reflection on the strategies of the leading actors of world politics for the development of the hydrogen economy and the transformation of global fuel and energy complex in the context of the tasks voiced at the Summit of Climate Leaders on April 22-23, 2021 (“reducing emissions during this critical decade”, “mobilizing public and private sector finances to ensure zero transition to a new clean energy economy”, “promoting transformational technologies of pure zero by 2050”). The article examines a numer of state strategies: 1) dialectical balance between the operational concepts of the methodical "matryoshka (triple) doll" (biosphere - human life - technosphere) in the European Green Deal, Alternative Energy and Hydrogen Economy projects; 2) achieving synergy of components in the quadrangle of economic and legal relations "Lex Mercatoria - Democratia Carboneum - Lex Petroleа - European Green Deal" when applying new technologies; 3) filling the national and international legal gap to ensure innovation in the field of energy at all stages (extraction, production, supply, transportation, transfer, storage of energy resources, design, construction, operation of energy facilities); 4) resource self-sufficiency and technological capabilities of using hydrogen, choosing the best option for the hydrogen value chain; 5) development of fuel and energy complexes of the European Union, the Republic of Korea, and Japan in terms of prospects for hydrogen energy and building a hydrogen economy based on a combination of national industrial traditions with innovative technologies. The article also deals with a set of institutional factors and legal norms for regulating the relationship between the subjects of national and global fuel and energy complexes in the context of the dynamics of demand for hydrogen and other types of fuel and energy resources in local and world markets. It gives the analysis of the effectiveness of government strategies to reduce dependence on imports of traditional types of energy sources and the development of "green" energy. The authors attempted to identify the priority tasks of energy diplomacy.
