Hydrogen fuel cell cars can go 300-400 miles per tank
Hydrogen fuel cell cars are an emerging technology that offers a clean and convenient alternative to conventional cars. They can go about 300-400 miles per tank. For example, the Toyota Mirai can travel up to 402 miles on a single tank of hydrogen, setting a Guinness World Record for the longest distance driven by a fuel-cell vehicle without refueling. The Hyundai Nexo, an SUV that runs on hydrogen, can go up to 380 miles on a full tank, while the Honda Clarity Fuel Cell, a sedan, can go up to 360 miles.
The range of a hydrogen car depends on several factors, such as the size and type of the hydrogen tank, the efficiency and power of the fuel cell or combustion engine, and the driving conditions and speed. For instance, driving at higher speeds can significantly reduce the range of a hydrogen fuel cell car. Additionally, the fuel cell typically requires a few cycles to reach optimum performance, which can impact the range achieved in the initial miles.
Hydrogen fuel cell cars have their own power plant on board, which converts hydrogen in the fuel tank into electricity through an electrochemical process. This electricity then powers the electric motor and/or charges the battery. This process is known as reverse electrolysis, where hydrogen reacts with oxygen to generate electrical energy.
One of the main advantages of hydrogen fuel cell cars is their short refueling time. It only takes about three to four minutes to refill the hydrogen tank of a BMW iX5 Hydrogen, making them ideal for long trips or remote areas. However, the high cost of hydrogen fuel and the lack of supporting infrastructure are challenges that hinder the widespread adoption of these vehicles.

Hydrogen is the most abundant element in the universe
Hydrogen fuel cell cars can go up to 1,003 kilometres (623 miles) on a single tank of fuel, as demonstrated by the Toyota Mirai in 2021. The Mirai has a certified range of approximately 650 kilometres (400 miles) under normal driving conditions. However, by adopting an "eco-driving" style, drivers were able to achieve the record-breaking distance of 1,003 kilometres. The Mirai was also able to be refuelled within five minutes.
Hydrogen is indeed the most abundant chemical element in the universe. It was formed in significant quantities during the Big Bang, along with helium. All of the hydrogen in the universe originated in the first few moments after the Big Bang, and it plays a vital role in the fusion reactions that power stars like our sun. These reactions produce heavier elements and release vast amounts of energy. For example, in the sun, hydrogen atoms are fused to form helium atoms, with a slight loss of mass during the fusion process. This process can be calculated using Einstein's famous equation, E=mc2. The energy released from fusing one kilogram of matter is enough to supply over 2.5 million New Zealand homes with their annual energy needs.
Hydrogen is the third most abundant element on Earth's surface, after oxygen and silicon. However, Earth's atmosphere contains very little hydrogen gas due to its low density, which allows it to escape the planet's gravity more easily than denser gases. Most of the hydrogen on Earth is found in compounds such as water (H2O) and hydrocarbons. Hydrogen has a variety of uses, including in the food industry, where it is used to convert oils into semi-solids for products like margarine. It is also used in rocket fuel, welding, hydrochloric acid production, and the creation of pure metals.
One of the most promising applications of hydrogen is in fuel cell technology for vehicles. Hydrogen fuel cell cars are powered by compressed hydrogen gas, which feeds into an onboard fuel cell stack. This stack transforms the chemical energy of the fuel into electrical energy, which then powers the car's electric motors. These cars produce zero tailpipe emissions, with the only waste being pure water. Hydrogen fuel cell cars can offer a long-distance range comparable to gasoline-powered cars and can be refuelled quickly.

Hydrogen fuel cell cars are zero-emission vehicles
Hydrogen fuel cell cars are related to electric cars but have some key differences. Unlike electric cars, hydrogen vehicles produce their own electricity, meaning their power does not come from a built-in battery. Instead, hydrogen cars have their own power plant on board, which converts the hydrogen in the fuel tank into electricity. This power plant is the fuel cell.
One of the main challenges facing hydrogen fuel cell cars is the lack of infrastructure for supplying hydrogen to retail outlets. For example, in June 2019, an explosion cut off the supply to nine out of 11 hydrogen stations in the San Francisco Bay Area, requiring diesel trucks to transport tanks of compressed hydrogen hundreds of miles. Additionally, creating a brand-new fueling network from scratch has proven to be expensive and unreliable, and the fuel is currently much pricier for drivers than gasoline or electricity.
Despite these challenges, hydrogen fuel cell cars have several advantages. They have shorter refuelling times than electric cars, taking only around five minutes to refuel at a hydrogen fuelling station. Additionally, hydrogen can be produced at times when there is an oversupply of electricity from renewable energy sources, such as wind or solar power. Hydrogen can also be produced anywhere there is access to electricity and water, even directly at filling stations. As the infrastructure expands, transportation distances could be significantly shortened, and hydrogen has the potential to make ecologically sustainable mobility possible.

Hydrogen fuel cell cars are more expensive to run than petrol or diesel cars
Hydrogen fuel cell cars are a zero-emission alternative to traditional gasoline and diesel vehicles. They are powered by fuel cells that convert hydrogen gas into electricity, which then powers the motor. While hydrogen fuel cell cars offer several advantages, such as long driving ranges and quick refuelling times, they are generally more expensive to run than petrol or diesel cars.
One of the main reasons for the higher running costs of hydrogen fuel cell cars is the cost of hydrogen fuel itself. Hydrogen fuel is considerably more expensive than gasoline or diesel fuel. This is partly due to the energy-intensive process of producing pure hydrogen, which involves "cracking" compounds like natural gas into pure hydrogen, with CO2 as a byproduct. Additionally, the infrastructure for supplying hydrogen to retail outlets is still relatively thin, which has made creating a fueling network from scratch more challenging and expensive.
The high cost of hydrogen fuel is reflected in the overall ownership costs of hydrogen fuel cell cars. Research has found that the lifetime cost of ownership for a fuel cell car is about 40% higher than a comparable gasoline vehicle and around 10% more than an electric vehicle (EV). This makes hydrogen fuel cell cars a more expensive option for consumers, even though they offer longer driving ranges and faster refuelling compared to EVs.
Another factor contributing to the higher running costs of hydrogen fuel cell cars is the maintenance and servicing requirements associated with the hydrogen fuel system. The system includes specialized components such as hydrogen tanks, fuel cell stacks, and plumbing, which require proper handling and maintenance to ensure safety and prevent the risk of hydrogen escaping or exploding. This specialized maintenance can add to the overall running costs of the vehicle.
Furthermore, the limited availability of hydrogen refueling stations can impact the convenience and cost-effectiveness of running a hydrogen fuel cell car. In some cases, drivers have had to set alarms for odd hours to reach a fueling station and obtain limited hydrogen fuel supplies. The scarcity of refueling stations can lead to longer travel distances and potential disruptions in the availability of hydrogen fuel, affecting the overall running costs for owners of hydrogen fuel cell cars.

Hydrogen fuel cell cars are refuelled in a similar way to petrol or diesel cars
The refuelling process for hydrogen fuel cell cars is similar to that of traditional petrol or diesel cars. At a hydrogen fuelling station, a nozzle from a fuel dispenser attaches to the receptacle on the vehicle to fill the tank. Hydrogen fuel cell cars can typically be refuelled in around five minutes, and they can travel about twice as far as conventional cars on an equivalent amount of fuel. This makes them a competitive option for long-distance driving with zero emissions.
The Toyota Mirai, for example, broke the world record for the distance driven on a single fill of hydrogen, covering over 1,000 kilometres. It was able to achieve this feat with a range of approximately 650 kilometres (400 miles) under normal driving conditions, thanks to its increased fuel cell efficiency and higher hydrogen storage capacity. After completing the record-breaking journey, the Mirai was refuelled within five minutes.
However, it is important to note that the availability of hydrogen fuel and fuelling stations is currently a challenge for hydrogen fuel cell car owners. While hydrogen fuel cell cars offer the convenience of short refuelling times, similar to petrol or diesel cars, the infrastructure for hydrogen fuelling stations is still being developed and expanded worldwide.
