According to recent analysis, the global green hydrogen market is expected to grow from USD 0.9 Billion in 2025 to USD 67.1 Billion by 2035, registering a robust CAGR of 54.4% during the forecast period. The drivers of decarbonization goals, declining electrolyzer costs, and expanded renewable generation capacity for solar, wind, and hybrid hydrogen hubs are facilitating a notable growth trajectory.
The accelerating demand for cost-competitive clean fuels and industrial decarbonization is transforming the hydrogen landscape. To illustrate, in 2025 Linde plc scaled their large-scale hydrogen hubs; Air Liquide developed next-gen refueling networks; Siemens Energy release multi-GW electrolyze platforms. While, larger scale companies, such as Nel ASA, Plug Power, ITM Power are developing modular electrolyzer systems and cross-border hydrogen infrastructures. The green hydrogen market is on the brink of rapid acceleration at least until 2035, with bullish reports indicating demand driven by net-zero policies; industrial decarbonization; and heavy mobility.
The global demand for clean hydrogen sources, especially to drive industrial decarbonization and contribute to heavy mobility and large scale renewable integration, is accelerating demand for green hydrogen. Electrolyzer technologies including alkaline, PEM, solid oxide are being scaled, hydrogen hubs, liquefaction facilities and cross border pipelines are being actioned to catalyze the cost effective production and conveyance of hydrogen. In 2025 for example, Linde plc is already opening hydrogen hubs globally, Air Liquide launched smart refueling networks, and Siemens Energy launched a gigawatt scale electrolyzer platform, which are evidently a sign of demonstrative investment and evidence green hydrogen is deeply central to the energy transition.
A major analogue constraint is high production costs and lack of infrastructure. High CAPEX for electrolyzers, renewable energy input costs, and a lack of transport and storage network development creates issues for scaling and adoption across cost constrained customer segments. The consolidation of projects around tier 1 industrial players also creates barriers to entry for smaller players.
The future could potentially look more positive if governments continue to roll out subsidies, hydrogen strategies at the leverage of climate goals, and international collaboration for clean fuel trade. Significantly the U.S., EU, Japan, and Middle East have all enact a multi-billion dollar hydrogen investment roadmap and including incentives for electrolyzer manufacturing and refueling infrastructure.
Around the world tariff treatments for renewable technologies and electrolyzers, and even cross border hydrogen trading, will affect project economics and capital flows. The production costs are increased from a high tariff on an imported electrolyzer or renewable energy components, which can slow the pace of adoption in price sensitive areas.
On the other side of the spectrum, low or zero tariffs and relevant free-trade agreements encourage technology transfer and economies of scale and cross-border hydrogen supply chains so that green hydrogen becomes more competitive at an international level.
