        abstract = {As of 2026, green hydrogen (H2) has transitioned from a theoretical decarbonization tool to a primary industrial energy vector. This paper provides a technical synthesis of the hydrogen value chain, emphasizing the 2025–2026 breakthroughs in high-efficiency electrolysis, such as Solid Oxide Electrolyzer Cells (SOEC) achieving over 80% efficiency. We examine the critical challenges of integrating these variable loads into modern smart grids and the role of "Industry 4.0" technologies—specifically Digital Twins and AI-driven predictive maintenance—in ensuring infrastructure reliability. The review concludes that while production costs have decreased by 25% since 2024, the scalability of green hydrogen remains contingent on standardized smart monitoring and robust policy frameworks.},
