The global green hydrogen market is on a remarkable growth trajectory, surging from USD 8.72 billion in 2024 to an estimated USD 188.12 billion by 2034, with an impressive CAGR of 35.95% from 2025 to 2034.
Green hydrogen market is growing on a humongous level with increasing numbers of attempts being made worldwide to restrict carbon emissions and shift toward green energy resources. Governments from all over the world are coming up with policies, subsidies, and incentives to promote the manufacturing of green hydrogen using renewable resources such as solar and wind energy. Furthermore, innovation in electrolyzer technology is enhancing efficiency and lowering production costs, which makes green hydrogen a more acceptable substitute for fossil fuels. The increasing need for green energy in sectors such as transportation, power generation, and chemical production is also propelling market expansion.
Furthermore, huge investments made by the industry leaders along with government-private cooperation are driving energetic growth in green hydrogen infrastructure. Japan, Germany, and America are among the countries quickly backing hydrogen projects. Enhanced consumption will likely create innovation and keep things on the go. The number of announced projects for low-emission hydrogen production has grown rapidly in the past year, and could push annual production to 38 Mt in 2030.
Governments globally are making policies, subsidies, and incentives for green hydrogen production and consumption. Germany, Japan, and America have published hydrogen strategies with R&D, infrastructure, and commercialization investments. The European Union's Green Deal and the hydrogen roadmap are driving high-ticket initiatives. The policies are set to establish a low-carbon economy by substituting fossil fuels with hydrogen in industrial and transport sectors. Furthermore, tax incentives, carbon pricing schemes, and financing of hydrogen production facilities are fueling market expansion, rendering green hydrogen economically competitive and equivalent to traditional fuels. For instance, as of October 2021, the industry had announced a cumulative deployment of nearly 6 GW electrolysis by the end of 2022 (equivalent to about 0.7 Mt p.a.5 renewable hydrogen supply), while actual deployment as of January 2023 stands at only 700 MW.
The transport industry is seeing increased adoption of hydrogen fuel cells in heavy-duty vehicles, buses, trains, and maritime use. Fuel cell electric vehicles (FCEVs) provide longer ranges and faster refueling than battery electric vehicles (BEVs), and as such, are well-suited to long-distance transport. South Korea and China are establishing hydrogen refueling station networks, and automobile giants such as Toyota, Hyundai, and Daimler are investing in fuel cell technology. In addition, the aviation and shipping industries are also exploring hydrogen-based propulsion systems to green long-distance transport, increasing demand for green hydrogen even further. In 2022, installed capacity in China grew to more than 200 MW, representing 30% of global capacity, including the world’s largest electrolysis project (150 MW). By the end of 2023, China’s installed electrolyser capacity is expected to reach 1.2 GW – 50% of global capacity – with another new world record-size electrolysis project (260 MW)
Green hydrogen is still much pricier than blue and grey hydrogen because of expensive electrolyzers and the dependency on renewable power. Electrolysis, being the main mode of production, uses a great deal of electricity and is more expensive than steam methane reforming (SMR) that involves the use of natural gas. Even with decreasing renewable energy costs, economies of scale remain out of reach. The development of infrastructure, like hydrogen transport and storage, remains another added cost. In the absence of economies of scale and technological advancements bringing costs down, green hydrogen can never expect to compete with cheaper fossil-fuel-based alternatives.
Large-scale hydrogen production facilities are being developed across the globe, stemming from both government and energy company investments. NEOM Green Hydrogen Plant in Saudi Arabia and Australia's Asian Renewable Energy Hub developments will be constructed to produce substantial volumes of green hydrogen for domestic consumption and for export. Renewable energy costs are reducing to the point where such projects are financially viable. These mega-projects will facilitate the creation of integrated hydrogen systems, from production and storage through distribution and final use. Green hydrogen will gain widespread acceptance in various industries with the development of economies of scale and increased infrastructure. For instance, in October 2023, the industry has announced 1,418 clean hydrogen projects, representing investments of about USD 570 billion in hydrogen value chains (up from USD 435 billion). Giga-scale projects (over 1 GW of electrolysis for renewable hydrogen supply or more than 200,000 Mt p.a. of low-carbon hydrogen) account for over USD 330 billion.

The Asia-Pacific region is also experiencing an unprecedented surge in the market for green hydrogen led by China, Japan, India, and Australia. China is pouring vast amounts of capital into the production of electrolyzers and renewable infrastructure with the vision of becoming the world's biggest exporter of hydrogen. China accounts for almost 90% of committed production capacity in Asia-Pacific, with several largescale renewable hydrogen projects (>100 MW) already committed. Japan is focusing on hydrogen fuel cell technology for mobility, and India initiated its National Green Hydrogen Mission to expand domestic production and export markets. Australia, having enormous solar and wind resources, is building large-scale hydrogen hubs to feed world markets. High infrastructure cost risk threats, availability of water, and policy standardization concerns could deter mass penetration in the country.
North America is experiencing strong growth in the green hydrogen market due to supportive government policies, growing investments, and technology improvement. The U.S. Department of Energy's Hydrogen Energy Earthshot targets cutting green hydrogen costs to $1 per kilogram by 2030 to drive industry growth. Large-scale hydrogen production projects are being funded by major firms, mainly in Texas and California, where there is plenty of renewable energy supply. Canada is also positioning itself as a major player owing to its vast hydropower resources that allow for cheaply produced green hydrogen. Yet, infrastructure constraints and policy coordination among states are still main bottlenecks to market growth within the region.
Proton Exchange Membrane (PEM) electrolyzers employ a solid polymer electrolyte to transport protons between the anode and cathode, with hydrogen and oxygen separated by it. They are lower-temperature devices (usually 50–80°C), enabling quick start-up time and high efficiency, which makes them suitable for coupling with intermittent renewable energy technologies such as solar and wind. PEM electrolyzers are highly compact and of high hydrogen purity and can be easily used in industrial and transportation on-site hydrogen generation. They are, however, not used very extensively due to the reason of high costs attributed to the fact that platinum and iridium are expensive catalyst materials used by them.
Refining is one of the largest consumers of hydrogen, which is used mainly in hydrocracking and desulfurization reactions to purify impurities from crude oil. Historically, refineries have used grey hydrogen (derived from natural gas), releasing significant quantities of COâ‚‚. Part of the pursuit for decarbonizing the world, green hydrogen is now increasingly becoming the cleaner option. Large energy companies, like Shell and BP, are investing in green hydrogen to replace conventional hydrogen in refineries. Pressure from carbon footprint reductions through regulations and increasing carbon pricing mechanisms are forcing refineries to deploy green hydrogen, and thus it is one of the key market segments for future growth.
