Overall, hydrogen fuel cell vehicles provide a different set of potential pros and cons to other types of vehicles.

One of the major pros might be the potential ability to provide cleaner fuel (in terms of the level of air pollutants and carbon emissions they produce), providing that the hydrogen production process can become cleaner and more sustainable. The process would also need to be scaled too.

One of the drawbacks of hydrogen fuel cell vehicles, is that they are currently not used in the numbers on the road that conventional vehicles, hybrid vehicles, and full electric battery vehicles are.


Some of the major challenges and barriers to greater production and use of hydrogen fuel cell vehicles are (according to a range of reports from,,, and

– The high cost of fuel cells (and also the cost of hydrogen fuel materials used in hydrogen fuel cell cars, and new hydrogen infrastructure)

– The limited availability of hydrogen fuelling stations (this has a two fold effect in that people won’t buy vehicles that don’t have fuelling stations available and companies won’t build fuelling stations without customers for them)

– And extracting hydrogen gas from methane has an environmental impact as it generates CO2 and carbon monoxide.


These challenges and barriers also mean there isn’t large scale manufacturing/production of hydrogen gas at the moment.

There’s also question of the fuel energy efficiency of hydrogen fuel cell vehicles compared to full electric vehicles.

These issues could start being addressed with higher volumes of new customers for hydrogen fuel cell vehicles, along with government subsidies and support (which could stimulate demand and development).

Like the development of electric cars, hydrogen fuel cell vehicles will get more advanced over time (as technology gets better and other developments are made). 

But, it’s unclear how many years developments and improvements in hydrogen fuel cell technology will take to help scale up use.


*Other Notes

These are generalized pros and cons of hydrogen fuel cell vehicles only.

Each brand and model of hydrogen fuel cell vehicle is obviously going to offer it’s own pros and cons, and each driver is going to have different requirements that impacts pros and cons.

There will continue to be different variables as technology changes and society changes.

Different countries and cities also have different energy mixes, and policies and regulations in places which may change the pros and cons of hydrogen fuel cell vehicles in different places.

How the vehicle is operated may be another variable to consider.

So, pros and cons can be vehicle, driver and location specific.


Firstly, What Is A Hydrogen Fuel Cell Vehicle?

We explain what a hydrogen fuels cell vehicle is, & provide some comparisons to other types of vehicles like electric and hybrid vehicles in this guide.


Potential Pros Of Hydrogen Fuel Cell Cars

Hydrogen Fuel Can Be Eco Friendly In Some Ways During The Car’s Operation

Several reports indicate that the only by-products created from hydrogen cars are heat and water vapor (steam)

In comparison, conventional cars may produce carbon emissions and air pollutants through the car’s tailpipe, which is a result of the combustion of petroleum based products

This might make hydrogen fuel cell vehicles a more sustainable form of transport in some ways


HVs Might Be More Fuel Efficient Than Conventional Cars

A document by indicates that hydrogen fuel cell vehicles might lead to a ‘…  50% reduction in fuel consumption, compared to a conventional vehicle with a gasoline internal combustion engine’

This is when taking into account the amount of energy from gasoline and hydrogen gas each type of vehicle is able to convert into propelling the vehicles. clarifies though that the type of hydrogen vehicle matters (fuel cell vs combustion engine):

‘Using a fuel cell to power an electrified powertrain including a battery and an electric motor is two to three times more efficient than using a combustion engine, although some of this benefit is related to the electrified powertrain (i.e. Including regenerative braking). This means that much greater fuel economy is available using hydrogen in a fuel cell, compared to that of a hydrogen combustion engine’


May Require Less Maintenance

A hydrogen fuel cell vehicle may have less internal moving parts compared to combustion engines, which may lead to lower maintenance related costs.

Additionally, if a hydrogen fuel cell vehicle is lighter in weight than a full electric vehicle (which may have a heavy electric battery), there may be less wear and tear on the vehicle.


May Have A Good Driving Experience In Some Ways

Similar to a full electric vehicle, hydrogen powered vehicles may be quieter and smoother for drivers than some conventional cars


May Have A Longer Driving Range Than Electric Vehicles

When looking at how far a full electric vehicle can travel on one full charge compared to how far a hydrogen fuel cell vehicle can travel on one hydrogen gas fill up, some reports indicate that a hydrogen fuel cell vehicle may be able to travel anywhere from 2 to 4 times further 

But, obviously it depends on the models being compared.


Refuelling Hydrogen Cars Is Relatively Quick

The amount of time it takes to pump hydrogen into a tank is essentially as quick as a conventional gasoline vehicle.

This is in comparison to charging a full electric vehicle’s battery, which can take hours 

EV’s with quick charge technology might take 20 to 40 minutes according to some reports.


There’s More Filling Stations Being Built Over Time

Government initiatives and auto manufacturers are investing in some cities to build more refuelling stations.

This can be city or town specific though.


Hydrogen Is Abundant

Hydrogen is the most abundant element on planet earth

So, scarcity may not be as much of an issue in some ways compared to other sources of energy

But, it does depend on how the hydrogen gas is produced i.e. from what energy source


Hydrogen Gas Can Be Renewable

Producing hydrogen gas from fossil fuel like methane/natural gas might be non renewable

But, a more renewable way might be via the electrolysis of water

According to some reports, a few of the more renewable electrolysis methods might include:

– Biological water splitting (using sunlight and microorganisms)

– Pyrolysis or gasification of biomass resources

– And, solar thermal water splitting 


Can Help Build Economic Independence Of A Country

When using petroleum based fuels, countries that have to import a certain % of their oil become dependent on the countries they are importing from.

Hydrogen based fuel can help reduce this dependence on foreign oil if sourced and produced locally/domestically.

Again though, it depends what energy source the hydrogen comes from as to whether this might be the case.


Fuel Cell Materials Might Have Alternatives

For example, some reports indicate tungsten carbide might be an alternative to platinum in hydrogen fuel cells 


There’s Still Room For More Improvements

Some of those improvements might include things such as:

– Technology can still get cheaper

– And, various features such as the range of the vehicle can be improved to increase the performance of the vehicles, but also to make hydrogen fuel cell vehicles more appealing to consumers


Potential Cons Of Hydrogen Fuel Cell Cars

HVs might be less efficient than full electric cars

The resource in the sources list indicates that full electric cars may be more efficient than hydrogen fuel cell cars

To paraphrase, a hydrogen fuel cell car might maintain 38 of the original 100 watts of energy, once hydrogen gas production, hydrogen to electricity conversion, and the electricity use in the motor is taken into account.

Other reports say the entire process of electrolysis, transportation, pumping and fuel cell conversion leaves only about 20 to 25 percent of the original zero-carbon electricity to drive the motor.

Comparatively, a full electric car maintain 80 of the original 100 watts.

Essentially, a hydrogen fuel cell might need double the energy.

Fuel Cells Are Currently Expensive outlines that the high cost of fuel cells is one of the major challenges for fuel cell vehicles

High costs mean hydrogen fuel cell vehicles cannot be as economically competitive as other types of vehicles


From [It’s probably even better to introduce hydrogen as a fuel source to ships, trains and large trucks before passenger vehicles like small to medium cars]


[Battery electric will probably always be cheaper to run than hydrogen vehicles because of their higher energy efficiency – potential savings of about $2000 a year] (


Hydrogen Is The Most Expensive Fuel Right Now

According to some reports, at the first retail stations, hydrogen fuel went for about $6 a gallon in the US, and this makes hydrogen the most expensive automotive fuel on the market. outlines that the cost of hydrogen production is similarly expensive in Australia. 

Having said this, some reports indicate that the cost is expected to come down in the future as investment in the fuel continues.


Hydrogen Fuel Is Not Renewable Or Eco Friendly Right Now

The most common method of hydrogen gas production right now is steam methane reforming from natural gas (some reports say about 95% of hydrogen gas production is done this way)

Fossil fuels like natural gas are classified as a scarce resource

Additionally, the production of pressurized hydrogen gas results in the emission of carbon dioxide and carbon monoxide

Some methods of producing hydrogen gas from pyrolysis could help make hydrogen gas production more renewable and eco friendly though.

This might especially be the case if renewable energy (like solar or wind) was used to provide the electricity for the pyrolysis process


Differing Reports On Wheel To Wheel Environmental Advantage Of Hydrogen Vehicles

Some reports say hydrogen sourced from natural gas is lower in emissions than electricity for full electric battery vehicles, and less than half of equivalent gasoline vehicle emissions.

But, other reports say emission reductions aren’t significant due to GHG emissions from the natural gas reformation process.

When you add in the amount of energy hydrogen fuel might require, and the energy conversion efficiency of hydrogen, compared to full electric vehicles, there might be more accuracy behind the hydrogen fuel production process being heavier in emissions.


The Current Number Of Hydrogen Fill Up Stations Are Limited

Compared to fuel stations for conventional cars, there’s far far fewer hydrogen fuel stations.

In some cities, there’s no hydrogen fuel stations.

There were less than 50 publicly available hydrogen refuelling stations in the United States in 2018. outlines that the limited availability of hydrogen fuelling stations limits the number (and production) of hydrogen-fueled vehicles because people won’t buy those vehicles if hydrogen refuelling stations are not easily accessible, and companies won’t build refuelling stations if they don’t have customers with hydrogen-fueled vehicles.

So, there’s a two fold flow on effect of limited numbers of fill up stations.


Hydrogen Fuel Stations & Infrastructure Are Not Cheap

Each station costs about $2 million to $3 million according to various estimates

So, there needs to be available capital if a new one is to be built, even as a basic requirement



[Hydrogen would need] … extensive hydrogen distribution infrastructure which would be required for refuelling automobiles.

Such an infrastructure could easily cost as much as $5,000 per vehicle or more


Cost Of Cars & Materials Is Expensive Comparatively

Platinum is one of the most commonly used catalysts for fuel cells, and some reports indicate that it costs almost $1,000 an ounce as a commodity.

When considering other materials and technologies used in hydrogen fuel cell vehicles, hydrogen vehicles might cost more compared to a gasoline or electric vehicle to either buy or lease.


First Buyers May Lose Out

If hydrogen vehicle technology changes a lot of the coming years and decades, initial buyers could see their re-sale prices decrease as the technology in their car becomes outdated or inferior


Potentially Dangerous In Some Ways

Storing pressurised hydrogen onboard a vehicle can pose several dangers such as invisible hydrogen flames in the event of a crash, and also the potential for explosions at hydrogen stations. also outlines that ‘Hydrogen fuel is hazardous because of the low ignition energy and high combustion energy of hydrogen, and because it tends to leak easily from tanks’


Hydrogen Storage Can Be Complex & Challenging

After production, hydrogen needs to be stored for transport, stored at fuel stations, and also stored in vehicle fuel tanks.

Storing hydrogen can be a challenge because it requires high pressures, low temperatures, or chemical processes to be stored compactly.

For consumer passenger cars, overcoming this challenge can be difficult because they often have limited size and weight capacity for fuel storage. outlines that ‘The problems of using hydrogen fuel in cars arise from the fact that hydrogen is difficult to store in either a high pressure tank or a cryogenic tank … Alternative storage media such as within complex metal hydrides are in development [to address this]’


Hydrogen Cars Aren’t Good In All Conditions & Climates

The performance of hydrogen-powered cars has limitations in different climate and weather conditions.

The water in the fuel cells can freeze when temperatures hit below freezing point.

And, the fuel cell components run the risk of overheating in hot conditions.

This is a limitation against conventional cars for example that have more flexibility in the weather/climate conditions they can be used in.


Limited Vehicle Choice

There are not as many hydrogen vehicle brands and models to choose from right now in comparison to conventional cars.


Supply, Infrastructure and Technology Perfection & Development Is Still Years Away

It’s going to take many years in order to perfect fuel cells’ conversion solutions, since developing newer fuel cell technologies are still in the transition period.

It will also take years to increase supply and infrastructure needs.


On supply, one potential issue at refuelling stations according to is:

Hydrogen fuelling stations generally receive deliveries of hydrogen by truck from hydrogen suppliers. An interruption at a hydrogen supply facility can shut down multiple hydrogen fuelling stations
