Green hydrogen (GH) has become an important solution for achieving global decarbonization goals and supporting a low-carbon future. To enable large-scale hydrogen production, storage, distribution, and use, this study examines the technological, financial, and policy challenges of building hydrogen infrastructure. Hydrogen can be a clean and flexible energy source for industry, transportation, and power generation, but its widespread use faces obstacles. These include high production costs, insufficient refilling infrastructure, energy losses, and complex storage requirements. This study provides a detailed look at current hydrogen production technologies, including electrolysers that use renewable energy. It also assesses innovations in storage systems, such as cryogenic, chemical, and underground solutions. Additionally, it explores the logistical and regulatory challenges of transporting hydrogen via pipelines, ships, and road trailers. The study pays special attention to the commercialisation issues of fuel cell technologies and the need for safety protocols and standardisation. Moreover, the paper stresses that addressing these challenges requires coordinated action among policymakers, industry leaders, and researchers. Strategic investments, technological innovation, and international cooperation are key to developing green hydrogen infrastructure and realising its potential as a foundational element of the global clean energy transition.
Keywords: Green hydrogen, hydrogen Infrastructure, electrolysis technology, hydrogen Storage, energy transition.
