Electric vehicle doyen Elon Musk once dismissed fuel cells as “fool cells.” While many of us are still coming to grips with electric cars, some experts think hydrogen is the next big fuel. These cars are often described as hydrogen fuel cell vehicles, meaning they use a fuel cell as opposed to a battery. In fact, EVs may just be the transition from fossil fuel to fuel cell electric vehicles (FCEVs) powered with hydrogen.

As Gregory Guillaume, Kia’s Vice President of Design, said: “My personal opinion, battery-powered electric vehicles can only be a transition (to) hydrogen.” Let’s look at the pros and cons of each.


Pros: FCEVs convert hydrogen – or other fuel – to electricity. This is the difference between EVs and hydrogen cars. Fueling a hydrogen car is just like buying regular gasoline and takes only 3 to 5 minutes. For a time-starved population, it makes more sense practically.

Cons: You charge EVs directly with electricity. It takes an hour, at least, to supercharge an EV and from 14.5 to 48 hours using a standard household outlet. This is too long for most people. Although the infrastructure is growing, not everyone lives in a location where public charging stations are available.

There are 41 public hydrogen refueling stations in California with the goal of 200 stations by 2025. In 2018, 25 FCEV buses were operating in California, versus only seven in other states. There is one public hydrogen refueling station each in Connecticut, Hawaii, Massachusetts, Michigan, and South Carolina. Another 27 are in development in those states, along with New York and Rhode Island.

In Europe, there are around 152 Hydrogen Refueling Stations in operation as of early 2019, with many more being built or planned. The fastest increase of Hydrogen Refueling Stations (HRS) being built is in Germany. In Australia, there are no hydrogen stations available. Toyota and Hyundai are the main contenders, but Mercedes-Benz and China’s Grove are also pursuing hydrogen fuel cell vehicles.

Long Range or Range Anxiety

Pros: With the exception of a few models (Tesla Motors in particular,) hydrogen cars typically have double the range of most battery-powered EVs. Even if individual owners don’t buy hydrogen, companies with fleets of trucks, buses, and delivery vans will be able to save time and money.

Cons: Most people buying EVs still grapple with range anxiety. The more affordable models travel roughly 140 to 190 miles on one charge. While this is enough for city driving and most work commutes, it can make some nervous, especially those in rural or suburban areas. In these instances, a hydrogen fuel cell vehicle might be more reassuring.

Make It & Transport It

Pros: EVs in the U.S. run on electricity made with fossil fuels. Owners charge EVs directly with electricity and, because they use an existing grid, there is no need to transport electricity.

Cons: In the U.S., for example, hydrogen is also created from fossil fuels. This is not the only way to do it. It is possible to create renewable hydrogen in several ways: from solar or wind electrolysis of water, from water vapor in the air, from crop waste, or biogas from landfills or wastewater treatment plants.

The next challenge is transporting hydrogen to service stations. It could be transported in a diesel truck to a service station, where the owner fills up and hydrogen is converted back to electricity again. But this makes little sense.

CSIRO in Australia developed a metal membrane that extracts hydrogen from liquid ammonia. This is a lot easier and cheaper to carry around as well as avoiding coal power. Each service station would then carry a liquid ammonia tank, membrane, and hydrogen refueling pump. But this is just one idea.

Go Out & Buy One – If You Can

Pros: Buying an EV is beyond the means of many Americans but still (currently) cheaper than an FCEV. An Audi E-Tron costs $75,000; the Hyundai Kona Electric and Tesla Model 3 both cost between $35,000 and $40,000; and the Nissan Leaf about $32,000. The latter vehicles are examples of the market trying to make EVs more affordable and accessible. There still isn’t a vigorous market in secondhand EVs.

Most Australians can’t afford an EV either. The average EV costs over A$60,000 but you can buy them for less. A Nissan Leaf starts from A$49,000, and the Hyundai Ioniq Electric starts at A$46,000 before on-road costs.

Cons: If you live in the U.S., there are only four FCEVs for sale or lease. However, each have a range of 312 to 380 miles. They are all 2019 models and have a starting price of around $59,000: Honda Clarity, Hyundai Nexo, Hyundai Nexo Blue, and Toyota Mirai. Hyundai is a big investor in hydrogen. If Hyundai is right, hydrogen fuel cell vehicles will be less money than EVs by 2030.

Running Costs

Pros: In Australia, it currently costs about $5.40 to travel 100 kms (62 miles) using electricity, compared to $16.65 to travel that distance using petrol. To look at it another way, this is only 30 cents compared to $1.23 per liter of fuel. So it is much less expansive than filling your car with petrol or diesel.

Cons: The obvious question is how much does it cost the owner of a hydrogen car to fill up? California Fuel Cell Partnership (whose motto is Farther, Quicker, Cleaner) says hydrogen costs $13.99 per kg (or $1.23 per liter of gas).

Fans of hydrogen say the price will fall. National Renewable Energy Laboratory (NREL) estimates, by 2020-2025, prices may fall to $8.00 from $10.00 per kg. At $3.50 per gallon of gas, a regular vehicle would cost $0.13 per mile but a hydrogen car using $8.00 per kg of fuel would cost $0.12 per mile. This is starting to look more promising.

The Hydrogen Economy

Wan Gang is the so-called father of EVs and vice chairman of China’s national advisory body for policy making. He says, “we should look into establishing a hydrogen society”.

Hydrogen cars depend on investment in the so-called hydrogen economy. The US Department of Energy has put $40 million towards H2@Scale, a hydrogen research program. At the moment, the US produces over 10 million metric tons of hydrogen, but this goes into refining oil and producing fertilizer.

For an idea of where the industry is going, look to where the investors are. Great Wall Motor is investing over $149 million in research and development of FCEVs. Toyota sells hydrogen cars already and has developed fuel cells for trucks, buses, and even a lunar rover. Meanwhile, the BMW i Hydrogen Next concept, shown in Frankfurt this year, is a result of its partnership with Toyota. This is a hydrogen fuel cell version of the X5 SUV and will be produced in small numbers in 2022.
