Green hydrogen is the "holy grail" of zero-emission fuel, produced by splitting water into hydrogen and oxygen using electricity from renewable sources, resulting in a fuel with a near-zero carbon footprint. Demand for low-emissions hydrogen grew by 20% in 2025 to close to 1 Mt, but this is less than 1% of total hydrogen demand . Green hydrogen is the fastest-growing segment with a CAGR of 15.33% , supported by government initiatives and investments in renewable energy projects . China is the global leader in green hydrogen projects, with operational and post-FID capacity reaching 1.2 Mt in 2025, accounting for almost half of the world total, followed by India (0.5 Mt) . India's National Green Hydrogen Mission targets an annual production of 5 million metric tons by 2030 . The levelized cost of green hydrogen is a major barrier, with renewable energy accounting for about 65% of its cost .
The urgent need to reduce carbon emissions and achieve net-zero targets is the primary driver . Decarbonization targets and climate commitments are a significant driver . Government initiatives, such as India's National Green Hydrogen Mission and the European Hydrogen Bank auctions, are accelerating adoption . Advances in electrolysis technology, such as high-efficiency solid oxide and anion exchange systems, are reducing energy consumption . Partnerships and joint ventures, like the MoU between Siemens, Guofu Hydrogen, and RCT GH Hydrogen, are advancing green hydrogen value chains .
The development of green hydrogen production capacity is a key trend, with projects in emerging economies like China and India leading the way . The use of green hydrogen in steelmaking, shipping, and heavy-duty transport is a key trend . The integration of green hydrogen with renewable energy storage to provide grid stability is a key trend . The emergence of a global green hydrogen trade, with export-oriented projects in developing economies, is a key trend .
High production costs remain the primary challenge, as green hydrogen production through electrolysis is energy-intensive and expensive . The lack of offtakers and insufficient demand-side incentives are real hurdles for investment, leading to project delays and cancellations . Infrastructure for storage, transport, and refueling is limited . Only 17% of exported blue hydrogen projects and 9% of export-oriented green hydrogen projects have taken FID .
The future of green hydrogen will be defined by significant cost reduction through technological innovation, economies of scale, and supportive policies. The Indian government aims for $2-$2.5/kg renewable hydrogen, and global efforts target $1/kg . Standards and certifications are critical for subsidy schemes and to support hydrogen commercialisation . Stronger supportive policies, including mandates and higher carbon prices, are needed to scale beyond present forecasts .
Analysts emphasize that green hydrogen is the ultimate goal for a zero-carbon economy, but its widespread adoption depends on overcoming the significant cost gap with fossil-based hydrogen. The next decade will be crucial for scaling up production and building the necessary infrastructure.
