The global green hydrogen market is witnessing significant growth, with a valuation of $7.98bn in 2024 and a projected compound annual growth rate of 38.5% from 2025 to 2030. Advancements in electrolysis technology, particularly proton exchange membrane and alkaline electrolysers, are driving down costs and enhancing the competitiveness of green hydrogen against conventional energy sources like natural gas. Countries such as Germany, Japan, and Australia are at the forefront of green hydrogen adoption, establishing localized manufacturing of electrolysers and implementing hydrogen roadmaps to bolster production, distribution, and utilization ecosystems. Industries like steel, cement, and transportation are turning to green hydrogen to decarbonize their operations, with plans to transition to hydrogen fuel cells in heavy-duty vehicles and even aircraft. Carbon pricing schemes and markets, notably in the European Union, are playing a crucial role in incentivizing green hydrogen projects and influencing corporate sustainability strategies. Leading energy and industrial players globally, including Plug Power, Siemens Energy, Iberdrola, Air Products and Chemicals, and Enel Green Power, are investing in green hydrogen initiatives to align with environmental goals and capitalize on the growing market demand. The article also highlights the proactive approaches of countries like Germany, Japan, and Australia in advancing green hydrogen technologies and infrastructure. Moreover, India has formulated its National Hydrogen Mission and Green Hydrogen Policy to position itself as a key player in green hydrogen production, aiming to produce 5 million metric tonnes annually by 2030. Collaborations with countries like Japan, Germany, and the UAE are envisioned to facilitate knowledge exchange and accelerate the development of the green hydrogen ecosystem.
