Press Release
Hydrogen Buses Market to Reach USD 64.35 Billion by 2035, Growing at a 38.6% CAGR as Transit Fleets Scale Up
Date : Nov 04, 2026
Pune, India, November 4, 2026 — The global Hydrogen Buses Market was valued at USD 2.46 billion in 2025 and is projected to reach USD 64.35 billion by 2035, expanding at a CAGR of 38.6% from 2026 to 2035, according to the latest Hydrogen Buses Market report by Ameco Research. The market is estimated at USD 3.41 billion in 2026. Transit agencies are moving from small pilot fleets to large orders, fuel cell costs are falling, and green hydrogen supply is expanding, which together make hydrogen one of the fastest-growing segments of zero-emission public transport.
Hydrogen buses fill a gap that battery electric buses struggle with: long daily mileage, 18–20 hour shifts, hilly or cold routes, and depots without the grid capacity for large-scale charging. With 300–500 km of range per fill and refueling in 10–15 minutes, they can replace diesel buses one-for-one. The 180-page study covers market size, bus types, fuel and fuel cell technologies, applications, regional demand, and the companies leading the shift.
Hydrogen Buses Market Size and Forecast
Hydrogen buses are zero-emission passenger buses powered by hydrogen, usually through a fuel cell that generates electricity for an electric drivetrain, and less commonly through a hydrogen internal combustion engine. They serve city transit, intercity and coach routes, airport shuttles, tourism, and school transport, and are sold as new vehicles or created by retrofitting diesel buses.
Ameco Research expects the market to pass USD 12.5 billion by 2030 and grow more than twenty-fold over the decade:
| Year | Market Size (USD Billion) |
|---|---|
| 2025 (Base Year) | 2.46 |
| 2026 | 3.41 |
| 2028 | 6.55 |
| 2030 | 12.58 |
| 2032 | 24.17 |

Why Are Transit Agencies Choosing Hydrogen Buses?
Zero-Emission Transit Mandates
Clean vehicle rules in the EU, China, South Korea, Japan, India, and U.S. states such as California require transit agencies to phase out diesel buses. Hydrogen gives operators a zero-emission option for routes where battery buses cannot easily cover the daily distance.
Range, Refueling Speed, and Depot Constraints
Charging hundreds of battery buses overnight can require expensive grid upgrades, while a single hydrogen station can serve a large fleet. Fast refueling also keeps buses in service longer, which matters for high-frequency city and intercity routes.
Public Funding and Falling Fuel Cell Costs
Programs such as the U.S. Regional Clean Hydrogen Hubs, EU Clean Hydrogen Partnership projects, German bus funding schemes, and Chinese purchase subsidies lower the cost of buses and stations. At the same time, higher production volumes, longer stack life, and components shared with trucks keep pushing fuel cell system prices down.
Hydrogen Buses Market Trends in 2026
- From pilots to fleets: Bologna began running Solaris hydrogen buses in 2026 as part of a planned 127-bus fleet, Ruhrbahn in Germany is adding 52 hydrogen buses with public funding, and Porto is deploying 18-meter articulated fuel cell buses on a bus rapid transit corridor.
- Fuel cell supply scales up: Ballard Power Systems secured an order from New Flyer for 500 heavy-duty fuel cell modules totaling about 50 MW, one of the largest bus fuel cell orders to date.
- India enters the market: Cochin International Airport introduced India's first hydrogen-fueled passenger buses, powered by green hydrogen produced on site, and Tata Motors announced hydrogen bus production in Lucknow.
- Green hydrogen gets cheaper: The cost gap between green and grey hydrogen has narrowed from 3–4 times in 2020 to roughly 1.5–2 times in some regions.
- Cheaper entry routes: Retrofitting existing buses can cut costs by around 40–50% versus new vehicles, and hydrogen combustion engine buses need roughly 20–30% lower upfront investment than fuel cell buses.
- Fuel price decides the business case: Hydrogen price at the pump is now the main factor in total cost of ownership, so new projects increasingly secure long-term supply contracts and shared refueling hubs before ordering buses.
Challenges to Wider Adoption
Hydrogen buses remain close to twice as expensive as diesel buses because of fuel cell stacks, carbon-fiber tanks, and low production volumes. Refueling stations are costly to build and maintain, and many cities still have few or none. Delivered hydrogen often costs more per kilometer than diesel or grid electricity, and some early European adopters have scaled back fleets when fuel costs rose. Rapidly improving battery electric buses, along with limited spare parts and technician training, add further pressure.
Hydrogen Buses Market Segmentation
By Bus Type
| Bus Type | Share (2025) | Key Highlights |
|---|---|---|
| Single-Decker | 36.4% | Standard 12 m and articulated city buses; the largest volume segment |

By Fuel Type and Fuel Cell Technology
Green hydrogen from renewable-powered electrolysis supplied 57.3% of revenue in 2025, because most funding schemes require low-carbon fuel and many agencies install on-site electrolyzers. Grey hydrogen held 28.1% and blue hydrogen 14.6%. Proton exchange membrane fuel cells (PEMFC) lead fuel cell technology with 47.9%, thanks to fast start-up and high power density, followed by alkaline (29.2%) and solid oxide fuel cells (19.6%).
