Hydrogen Trucks in India: Top 10 Most Frequently Asked Questions Answered

India is speeding towards cleaner transportation, and hydrogen trucks are becoming fast-trackable and viable substitutes for traditional diesel trucks. Hydrogen is being utilized as the fuel here, and this can reduce carbon emissions and deliver better energy security. With every new technology, questions and uncertainties arise. Below, we address the top 10 questions about hydrogen trucks in the Indian context and give you simple and concise answers to help you understand this new technology.

Here are the answers to some of the most common questions about hydrogen trucks:

1. What is a Hydrogen Truck?

A hydrogen truck is a type of vehicle that employs hydrogen as its main fuel to power its engine. There are two wide categories:

• Hydrogen Fuel Cell Trucks: Hydrogen gas fuel powers the truck using electricity through a fuel cell that energises electric motors to propel the vehicle. The technology produces no other output except water vapour, which makes the solution clean.
• Hydrogen Internal Combustion Engine (ICE) Trucks: In these vehicle, hydrogen is burned within an internal combustion engine as in the case of normal diesel engines that burn it. They do not burn any carbon dioxide but may emit nitrogen oxides (NOx), an emission.

2. How Do Hydrogen Fuel Cell Trucks Work?

Hydrogen fuel cell trucks move by using electrical energy and converting it to chemical energy. That’s a brief description of what occurs.

• Hydrogen Storage: Compressed hydrogen is stored in cylinders within the truck.
• Fuel Cell Operation: Delivered to a fuel cell where it is mixed with oxygen in the atmosphere and produces electricity by chemical reaction. This is used to power the truck’s electric motor.
• Emission: The only reaction emission is water vapour, and thus zero toxic emissions.

The technology facilitates efficient energy conversion and minimises greenhouse gas emissions.

3. What is the range of Hydrogen Trucks in India?

Hydrogen truck range depends on hydrogen tank capacity, weight of the vehicle, and road slope. Tata Motors has initiated hydrogen fuel cell-based heavy-duty truck trials for a range of 300 to 500 km on refuel in India.

4. How Long to Refuel a Hydrogen Truck?

Refuelling time is the key benefit of hydrogen trucks over battery-electric vehicles. Refuelling a hydrogen truck will consume between 10 and 20 minutes, varying with station capacity and truck tank size. Quick turnaround approximates conventional diesel refuelling time, and thus hydrogen trucks become a viable prospect for long-distance trucking.

5. Are Hydrogen Trucks Safe?

Safety is of very high concern when handling any fuel. Hydrogen vehicles possess the highest degree of safety measures to handle hydrogen’s character:

• Hydrogen Characteristics: Hydrogen gas is odourless, colourless, and non-toxic. Hydrogen is extremely flammable, but it dissolves instantaneously in the air.
• Vehicle Design: Hydrogen pickup trucks are designed with strong safety components, such as leak detection sensors, shut-off valves, and high-strength storage tanks, for secure use.

Secondly, the fast dissipation of hydrogen guarantees that in the event of a leakage, it won’t be nearly as risky a fire threat as liquid fuels on the ground.

6. How does the cost of hydrogen fuel compare with diesel in India?

The cost of hydrogen fuel varies based on production technologies and geography. Hydrogen fuel is currently more expensive than diesel per unit of energy, as of early 2025. Nevertheless, with ongoing innovation in production technology and economies of scale, the cost of hydrogen will decrease in the future. Government policies and incentives for the utilisation of clean energy can also render hydrogen an economical fuel for transportation.

7. What infrastructure exists for Hydrogen Refueling in India? 

The availability of hydrogen refuelling stations is crucial to the widespread use of hydrogen trucks. India is developing additional hydrogen infrastructure in 2025:

• Pilot Projects: India’s Government has initiated five pilot projects to run hydrogen-fueled buses and trucks under the National Green Hydrogen Mission. The five projects involve 37 hydrogen-fueled buses running on 10 routes in the nation, such as Greater Noida–Delhi–Agra and Ahmedabad–Vadodara–Surat.

• Collaborations: Private and public sector enterprises, including Tata Motors and Indian Oil Corporation Limited (IOCL), are joining hands to create hydrogen refuelling stations to facilitate the deployment of hydrogen fuel vehicles.

In spite of these developments, the existing infrastructure is not as extensive as that of traditional fuels, and this is a limitation to the use of long-distance hydrogen trucks.

8. Can Existing Diesel Trucks Be Converted to Hydrogen?

Retrofitting hydrogen operation capability on diesel trucks is technically feasible but not simple. Diesel truck conversion kits to run on hydrogen are under development but there are issues:

• Technical Complexity: Hydrogen conversion involves extreme changes in the fuel system, engine, and safety features.
• Cost: Conversion is costly, typically almost as close as buying a new hydrogen truck.

Even with these odds, fleet owners would be ready to buy dedicated hydrogen trucks instead of recycling old diesel trucks.

9. What are the differences between hydrogen trucks and electric trucks in India?

Hydrogen and electric trucks are both emission-saving trucks but very different:

• Refuelling/Recharging Time: Hydrogen trucks are refuelled in 10 to 20 minutes, whereas electric trucks are charged for several hours even if they are rapid-charged.
• Range: Hydrogen trucks have a larger range (400-600 km) compared to electric trucks, whose range is up to 250-350 km on a single charge. It is simple in the case of commodity carriage over distances in India, where unintermittent transit is required.
• Infrastructure: While charging stations on the electric truck routes are more prevalent in India’s EV drive, hydrogen refuelling stations are still in a nascent stage.
• Efficiency: Battery-electric tractor-trailers are more efficient because electricity is directly used to propel, and hydrogen. Additionally, it has to be first converted into electricity, so they are ever so marginally less energy efficient. Hydrogen is lighter, though, so that reduces trucks’ need always to need to be recharged.
• Weight Factors: Hydrogen tanks are lighter than heavy battery packs, so hydrogen powered semi trucks have more to carry than electric ones.

While electric trucks are best positioned for short-range goods transportation, hydrogen trucks are best positioned for long-range transportation and high-power output uses like mining and construction.

10. What are the Steps being taken by the Indian Government to Promote Hydrogen Trucks?

The Indian government is encouraging hydrogen as a green alternative fuel through a number of policies and initiatives:

• National Green Hydrogen Mission (NGHM)

Launched in 2023, the mission would turn India into the world’s largest producer of green hydrogen and minimise the country’s dependence on fossil fuels.

The mission has an incentive policy of ₹19,744 crores to encourage hydrogen production, electrolyzer unit production, and refuelling stations of hydrogen fuel.

Heavy trucks transport is one of the big plans with various players undertaking pilot operations of hydrogen fuel cell trucks.

• Pilot Operations for Hydrogen-Fueled Trucks

The Ministry of New and Renewable Energy (MNRE) has already established various pilot projects to make hydrogen-powered trucks and buses run on Indian roads.

Tata Motors, Ashok Leyland, and Reliance Industries have partnered with Indian Oil Corporation (IOC) and NTPC to develop hydrogen fuel trucks.

The government is establishing hydrogen fuel corridors along high-speed corridors like Delhi-Mumbai and Bengaluru-Chennai to enable commercial fleet operations.

• Incentives to Fleet Operators

Faster Adoption and Manufacturing of Hybrid and Electric Vehicles (FAME) India Scheme would also be applicable to hydrogen vehicles.

Tax exemption and subsidies are also being considered for logistics companies that fit hydrogen kits on trucks and hydrogen generator for diesel vehicles.

• Public-Private Partnerships for Hydrogen Infrastructure

Large Indian oil and gas companies such as Indian Oil, Bharat Petroleum (BPCL), and Hindustan Petroleum (HPCL) are investing in hydrogen supply and production.

Indian Railways is also experimenting with hydrogen fuel cells for trains due to the government’s hydrogen fuel-based mode of transportation drive.

• Hydrogen Deals with Global Leaders

India has entered into hydrogen cooperation with Japan, Germany, and Australia in order to share technology and drive production capability.

Various foreign firms are investing in the Indian economy in order to build hydrogen fuel cell manufacturing facilities as well as manufacturing plants for hydrogen kit for vehicles.

These all are efforts that clearly show India’s serious intentions for becoming a world hub for hydrogen fuel trucks so that India is ahead of the world for green transport.

Last Words: Is India Ready for Hydrogen Trucks

While hydrogen fuel lorries are magnificent prospects for Indian logistics, large-scale use will be subject to the advancement of technology and cost. The government of India’s proactive efforts through incentivisation, infrastructure with the industry indicate that it’s at the centre of Indian future green transportation.

For commercial fleet truck owners, hydrogen fuel vehicles are the transportation of the future for longer range, quicker refuelling, and lower carbon emissions. But higher purchase price and fewer refuelling stations are challenges to be faced.

With continued technology developments and government incentives, hydrogen truck engines, and hydrogen fuel kits for vehicles will be a viable choice for India’s commercial vehicle market in the future.
