Hydrogen cars are more expensive to buy and refuel than electric cars
Hydrogen cars are more expensive to buy than electric cars. This is partly due to the cost of hydrogen fuel cells, which are often made from expensive platinum. Hydrogen fuel is also costly, with prices varying from $75 to $125 per tank, or around $20 to $36 per kilogram, depending on the fuel tank size. In comparison, it costs around $6 to $10 to recharge an electric vehicle, depending on the battery storing capacity and charging station.
The high cost of hydrogen fuel is due to the scarcity of the resource, as very little hydrogen has been processed for use in FCEVs. Hydrogen is most often used in oil refining and industrial processes, and the process of refining hydrogen creates more greenhouse gases than generating electricity for EVs. Hydrogen is also difficult to transport, as it must be stored under pressure, and it easily leaks. This means that an enormous amount of hydrogen would need to be created and moved via pipelines or trucks to refueling stations.
The lack of refueling stations is another factor that makes hydrogen cars more expensive to refuel than electric cars. As of 2023, there were over 1000 refueling stations globally, with half of these in Germany. In the US, there are only 52 publicly available hydrogen stations, all but one of which are in California. In the UK, there are only nine hydrogen stations, compared to 8,300 petrol stations and 31,000 public charging locations for electric vehicles. This lack of infrastructure means that buyers are less likely to purchase hydrogen cars, which in turn makes companies less likely to build new refueling stations.
While hydrogen cars are more expensive to buy and refuel than electric cars, they do have some advantages. Hydrogen cars can be refueled in around 5 to 10 minutes, which is much quicker than the 4 to 8 hours it takes to charge an electric vehicle. Hydrogen cars also have a longer driving range, with a Toyota Mirai able to travel 357-400 miles, compared to 200-250 miles for most electric cars.

Hydrogen cars are more environmentally friendly but less energy efficient
Hydrogen fuel cells can be 100% renewable and environmentally friendly, making hydrogen cars a good option. They release pure water vapour and filter out ultrafine dust from the atmosphere, leading to eco-friendliness. However, the consumption of lithium and cobalt-like materials results in environmental damage.
Electric vehicles (EVs) are also environmentally friendly as they reduce emissions and have a lower carbon footprint. They reduce fuel usage by running on electricity only and they don’t produce any tailpipe emissions, which helps lower pollution. However, the manufacturing and disposal of EV batteries can lead to pollution and resource depletion.
While hydrogen cars are more environmentally friendly, they are less energy efficient than EVs. Electric cars can convert 80% of the electricity in the battery into energy, making them very efficient. Hydrogen cars can convert a maximum of about 40% currently.
Another factor to consider is the cost. Hydrogen cars are more expensive than electric cars. The two mainstream hydrogen cars on sale in the U.S. today, the Toyota Mirai and Hyundai Nexo, start at around $50,000 and $60,000, respectively. A growing number of EVs cost less, thanks to the falling price of lithium-ion batteries.
In addition, there is a lack of infrastructure for hydrogen cars. There are over 1000+ refueling stations globally for hydrogen cars as of 2023, compared to thousands of powering/charging stations for EVs. This has created a "chicken-and-egg problem" where buyers don’t want hydrogen cars because they can’t fill them, and there are no filling stations because there are no cars.

Hydrogen cars are quicker to refuel, but there are fewer refuelling stations
Hydrogen fuel cell cars are quicker to refuel than electric vehicles (EVs). They can be refuelled in three to ten minutes, which is roughly the same length of time it takes to refuel a petrol or diesel car. In comparison, charging an EV can take anywhere from less than 30 minutes to overnight, depending on the power of the charger and the car in question.
However, hydrogen refuelling stations are not as readily available as EV charging stations. As of 2023, there are over 1,000 hydrogen refuelling stations globally, compared to thousands of charging stations for EVs. In the UK, there are only nine hydrogen stations, compared to 8,300 petrol stations and 31,000 public charging locations for EVs (not including home plugs). This lack of infrastructure is a significant drawback for hydrogen cars and has been cited as a reason why hydrogen vehicles have not been successful. Buyers are reluctant to purchase hydrogen cars due to the limited availability of refuelling options, and companies are hesitant to build more stations because there is a low demand for them.
The higher cost of fuelling hydrogen cars is another factor that contributes to the lack of demand for hydrogen refuelling stations. Filling a hydrogen gas tank typically costs between $75 to $125, depending on the tank size, whereas recharging an EV battery costs around $6 to $10. Additionally, hydrogen cars are generally more expensive to purchase than EVs, with mainstream hydrogen cars starting at around $50,000 to $60,000, while a growing number of EVs are becoming more affordable due to the decreasing price of lithium-ion batteries.
While hydrogen cars offer the advantage of quick refuelling, the limited availability and higher costs associated with refuelling stations make them less convenient and accessible than EVs.

Hydrogen cars are less complex but have a longer range than electric cars
Hydrogen fuel cell cars are often touted as a potential replacement for electric cars, but how do they compare? Hydrogen cars are less complex than electric cars, but they offer a longer range and quicker refueling times.
A hydrogen car consists of a hydrogen tank that stores highly-pressurized hydrogen gas. The gas is released in a controlled manner to come into contact with the anode and cathode in the fuel cells. An electrochemical reaction between the anode and cathode breaks the hydrogen molecules into protons (water) and electrons (electricity), which powers the car. This electricity is then stored in a battery, which powers the motor that moves the wheels. This process is relatively straightforward, and the fuel can be pumped in a similar amount of time as gasoline.
In comparison, electric vehicles (EVs) are powered by electricity stored in rechargeable battery arrays. These batteries must be plugged into a mains outlet to charge, which can take longer than refueling a hydrogen car. The battery array then drives an electric motor, which creates a magnetic field that turns a rotor shaft, driving the car's wheels. While some electric cars use one motor, others have two or three, offering more power.
The driving range of an electric vehicle depends on the model and price, with more expensive EVs offering longer ranges. The range of EVs can vary from 150 to 375 miles, while hydrogen cars typically offer a range of 400 to 600 miles, depending on the tank size. This longer range, combined with quick refueling, makes hydrogen cars attractive, especially for long-distance travel.
However, it is important to note that hydrogen cars are generally more expensive than electric cars, and the infrastructure for refueling hydrogen vehicles is still limited. Additionally, while both types of cars produce zero emissions directly, the manufacturing and disposal of EV batteries can lead to pollution and resource depletion, an issue that hydrogen cars do not face to the same extent.
In conclusion, hydrogen cars offer less complex systems with longer ranges and quicker refueling, but they are more expensive and have limited refueling options. Electric cars, on the other hand, are more convenient, reliable, and widely available, making them a more popular choice for consumers at present.

Hydrogen cars are safer than electric cars, despite hydrogen being highly flammable
Hydrogen fuel cell vehicles are more efficient than petrol or diesel cars, but they are not as efficient as electric battery-powered vehicles. Electric vehicles (EVs) are powered by electricity, stored in a rechargeable battery array, which drives an electric motor that creates a magnetic field to turn a rotor shaft, which drives the car's wheels.
Hydrogen cars, or hydrogen fuel cell electric cars, are driven by an electric motor powered by an electrochemical reaction. This occurs when high-pressure hydrogen gas combines with oxygen and is fed to hydrogen fuel cells to produce electricity and water vapour. Hydrogen cars can be refuelled much faster than electric cars, and they have a longer driving range. However, hydrogen cars are more expensive and less efficient, with limited infrastructure for refuelling.
Despite hydrogen being highly flammable, hydrogen cars are considered safe. Hydrogen cars' fuel tanks are designed to withstand severe collisions, and some can even survive close-range gunfire. In the event of a fire, hydrogen-powered vehicles can flare the fuel, burning it out completely with minimal damage to the vehicle. This is in contrast to gasoline-fuelled vehicles, where a fire or explosion is more likely to cause extensive damage.
While no fuel is 100% safe, green hydrogen has been shown to be safer than conventional fuels in several aspects. Hydrogen is not toxic, unlike traditional fuels, and it produces only water when used in vehicles. Additionally, hydrogen generally has properties that make it safer to handle than conventional fuels.
