Prospects for the use of hydrogen energy in Russian regions taking into account the sectoral specialization of their economies

This article studies the conditions for developing hydrogen energy, taking into account foreign and domestic experience. It focuses on the sectoral usage of hydrogen in Russian regions given the restructuring of the energy sector to reduce resource capacity and increase energy efficiency, including through the use of renewable sources and the development of hydrogen energy. The study determines the conditions for developing hydrogen energy in Russian regions, taking into account location, sectoral specialization, and export opportunities. The research uses methods of the systematization, analysis, and comparison of analytical data from Russian and international studies on the development of hydrogen energy. The hypothesis is that the heterogeneity of the conditions for the development of hydrogen energy in Russian regions determines their different potential: the localization of the extractive industry, a strong industrial base, and energy efficiency are starting advantages for the introduction of hydrogen technologies. The article focuses on the identification of the general and specific conditions contributing to the development of hydrogen energy in Russian regions and an assessment of successful world practices for the national economy and individual regions. The results supplement the theoretical aspects and systematize the data of cases of hydrogen energy development and highlight the spatial development of hydrogen energy infrastructure. This allows regions to diversify sources of GRP growth, integrate innovative solutions, and improve the efficiency of industry and the economy as a whole.
