The global green hydrogen supply chain market is witnessing remarkable growth, propelled by the global drive for clean energy and the need for decarbonization. Industries worldwide are increasingly embracing green hydrogen to reduce carbon emissions and meet sustainability goals. This expansion is supported by advancements in hydrogen production technologies, increased infrastructure investments, and favorable government policies promoting renewable energy. Green hydrogen, produced through electrolyzing water with renewable sources like solar and wind power, is becoming a key player in various sectors such as transportation, energy storage, and industries seeking cleaner alternatives to fossil fuels. Despite challenges like high production costs and infrastructure requirements, ongoing innovation and collaboration are paving the way for a promising future market. Key highlights include the projected market size exceeding USD 154 billion by 2033, a substantial increase in green hydrogen production share, and the expected cost reduction to USD 1.5 per kg by 2030. Europe stands out as a leader in green hydrogen adoption, with significant commitments to electrolyzer capacity expansion. Both government policies and private sector investments are driving market growth, with opportunities emerging in industrial decarbonization and export potential. While challenges like production costs and infrastructure limitations persist, initiatives are underway to tackle these obstacles and leverage the full potential of green hydrogen in the global energy landscape.
