The accelerating energy transition, driven by climate change mitigation goals and the need for low-carbon development, requires a fundamental transformation of energy systems toward higher efficiency and sustainability. In this context, hydrogen has emerged as a key vector for integrating renewable energy sources, balancing energy systems, and decarbonizing hard-to-abate sectors. This article aims to investigate the role of hydrogen in advancing energy efficiency and supporting the development of sustainable energy systems. It focuses on identifying current trends, technological preconditions, and prospects for hydrogen deployment in Ukraine and Europe within the broader energy transition framework. The study applies to a comparative and system-based analysis of hydrogen production pathways, including grey, blue, and green hydrogen, with particular emphasis on the environmental and efficiency implications of green hydrogen. The research also employs energy system analysis to determine the role of hydrogen within the evolving energy balance structure and its interaction with renewable energy sources. The findings demonstrate that hydrogen can significantly improve energy efficiency by enabling sector coupling, enhancing energy storage capabilities, and facilitating the integration of intermittent renewable energy sources. Green hydrogen, produced from renewable electricity, is identified as a critical component of sustainable energy systems due to its low environmental impact. The study highlights key application areas, including energy, transport, and industry, and examines technological, economic, and safety challenges related to hydrogen production, storage, and distribution. The value of the research lies in providing a structured understanding of hydrogen’s role as a driver of sustainable energy transformation and offering insights into its strategic implementation in the context of energy transition policies.
