India is exploring hydrogen-powered vehicles as another option for reducing dependence on petrol and diesel. Unlike conventional engines, a hydrogen fuel-cell electric vehicle (FCEV) uses hydrogen to generate electricity, which powers an electric motor. The main emission from the vehicle is water, making it a potentially clean mobility solution when the hydrogen itself is produced using renewable energy.
How does a hydrogen car work?
Hydrogen stored in high-pressure tanks is supplied to a fuel cell. The fuel cell combines hydrogen with oxygen from the air to produce electricity. This electricity drives the electric motor, while water and heat are produced as by-products.
Unlike a battery-electric car, a hydrogen car does not need a large battery to store all its driving energy. Hydrogen can also potentially be refuelled much faster than a battery can be charged.
What is India doing?
India is still at an early/pilot stage for hydrogen mobility, rather than having a mass-market hydrogen passenger-car ecosystem.
The Government's National Green Hydrogen Mission aims to establish India as a global hub for green hydrogen production and use. The mission has an initial outlay of ₹19,744 crore, including support for pilot projects and hydrogen infrastructure.
In March 2025, the government announced five hydrogen transport pilot projects involving 37 buses and trucks and nine hydrogen refuelling stations. These include both fuel-cell and hydrogen internal-combustion vehicles operating on different routes.
Indian companies are also developing the technology. Tata Motors has supplied hydrogen fuel-cell buses to Indian Oil for evaluation, while Indian Oil has developed hydrogen production and refueling facilities as part of its hydrogen programme.
Why hydrogen is attractive for India
Hydrogen could be particularly useful for buses, trucks and long-distance transport, where long driving ranges and quick refuelling are important. India's Green Hydrogen Mission specifically identifies long-haul mobility as an area where hydrogen could contribute to decarbonization
Other potential advantages include:
Zero tailpipe carbon emissions from fuel-cell vehicles
Fast refueling compared with conventional battery charging
Potentially long driving range
Reduced dependence on imported petroleum
Opportunity to use India's growing renewable-energy capacity
What are the challenges?
The biggest challenge is infrastructure. Hydrogen refueling stations are currently very limited compared with petrol pumps and EV charging stations.
Hydrogen production is another important issue. A hydrogen vehicle is not automatically a zero-carbon vehicle simply because it uses hydrogen. Green hydrogen, produced using renewable electricity, offers the strongest environmental benefits.
Hydrogen storage, transportation, fuel-cell cost, station investment and overall hydrogen price also need to become more economical before mass adoption.
India has already established automotive safety standards, including AIS-157, covering safety and procedural requirements for compressed gaseous hydrogen fuel-cell vehicles.
Hydrogen vs EVs
For private cars, battery EVs currently have a major advantage because India's EV charging network is developing much faster and electric cars are already commercially available.
Hydrogen may therefore find its strongest early applications in commercial vehicles, buses, heavy trucks and long-distance transportation, rather than immediately replacing battery-electric passenger cars.
The road ahead
Hydrogen cars are not yet a mainstream option for Indian consumers in 2026. India is currently building experience through demonstrations, pilot vehicles, hydrogen production projects and refueling infrastructure.
The long-term opportunity is significant, but mass adoption will depend on the cost of green hydrogen, availability of refueling stations, vehicle prices and government and industry investment.
In short, hydrogen may not replace EVs in India—it could complement them. Battery EVs are likely to dominate many passenger-car applications, while hydrogen could become increasingly important for heavy-duty and long-distance mobility.
