Hydrogen fuel availability is limited
Hydrogen fuel cell cars, such as the Hyundai Nexo and Toyota Mirai, are an exciting prospect for drivers. However, one of the main disadvantages of these vehicles is the limited availability of hydrogen fuel.
As of 2024, there are only 54 hydrogen refuelling stations in the United States, with most concentrated in California. In contrast, California has over 10,000 gasoline stations. This disparity in availability makes it challenging for hydrogen car owners to reliably access fuel. The situation is further exacerbated by the fact that some stations are not always operational due to maintenance issues or other problems. For example, Shell recently closed seven public hydrogen fuel stations in California, reducing the already limited refuelling options for hydrogen car owners.
The limited availability of hydrogen fuel can lead to higher prices. With a small network of retail stations, prices for hydrogen fuel tend to be higher than for gasoline. For instance, in late 2022, the cost of hydrogen fuel in California ranged from $10 to $17 per kilogram, which is significantly more expensive than the cost of gasoline. While car manufacturers have offered incentives such as complimentary hydrogen fuel for limited periods, the high costs of refuelling remain a concern for drivers once these incentives expire.
To address the limited availability of hydrogen fuel, efforts are being made to expand the number of refuelling stations. The U.S. Department of Transportation Federal Highway Administration (FHWA) established the National Alternative Fuels Corridors grant program in 2022 to support the deployment of hydrogen fuelling infrastructure. Additionally, predictive models, such as the Prognostics Health Monitoring (PHM) model, are being developed to improve station availability and consumer confidence. This model can help station operators anticipate maintenance needs, minimise disruptions, and improve the overall fuelling experience for hydrogen car owners.
In conclusion, while hydrogen fuel cell cars offer several advantages, the limited availability of hydrogen fuel remains a significant challenge. Efforts to expand fuelling infrastructure and improve station availability are ongoing, but it is unclear when these improvements will be fully realised. In the meantime, hydrogen car owners may continue to face challenges in reliably accessing fuel and dealing with the potential high costs associated with refuelling.

Hydrogen fuel stations are expensive
In 2024, there were only 54 retail hydrogen stations in the United States, with most concentrated in California. The limited number of stations, coupled with the high demand for hydrogen fuel, results in higher prices for consumers. For example, at a hydrogen station in Concord, California, it costs $36 per kilogram of hydrogen, which is significantly more expensive than gasoline.
The cost of hydrogen fuel can also vary depending on the location of the station. In the Bay Area, for instance, the price of hydrogen has been reported to be as high as $27 per kilogram. This variability in pricing makes it challenging for drivers to predict their fuelling expenses accurately.
To address the high costs associated with hydrogen fuel stations, the Inflation Reduction Act of 2022 provides a tax credit of up to $3 per kilogram of hydrogen for projects with low-lifecycle greenhouse gas emissions. This initiative aims to stabilize and expand the market for hydrogen fuel producers.
As the demand for hydrogen fuel cell electric vehicles (FCEVs) increases, the business case for constructing additional stations with higher capacities becomes more attractive. This expansion of the hydrogen fuelling infrastructure is expected to lead to lower fuel costs per kilogram, making hydrogen fuel more accessible and affordable for consumers.

Hydrogen fuel cells are costly to replace
The high cost of platinum is a significant factor in the overall expense of hydrogen fuel cells. While other materials, such as non-precious metals, can be used to reduce costs, they often lack the necessary performance and durability offered by platinum. This means that platinum remains the preferred choice for hydrogen fuel cell manufacturers, despite its high price.
The high cost of replacement fuel cells can be a significant financial burden for drivers of hydrogen fuel cell cars. Not only are the fuel cells themselves expensive, but the maintenance and upkeep of these vehicles can also be costly. This includes the price of hydrogen fuel, which is typically higher than that of gasoline or electric vehicle charging.
The limited infrastructure for hydrogen refueling also contributes to the high cost of replacement fuel cells. With a small number of refueling stations, drivers may need to travel further to find a working station, increasing the overall cost of refueling. This lack of infrastructure can also lead to higher prices for hydrogen fuel, as the small network of retail stations can charge a premium for their product.
While there are some disadvantages to hydrogen fuel cell cars, such as the cost of replacement fuel cells, it is important to note that this technology has several benefits as well. Hydrogen fuel cell cars produce no tailpipe emissions, have short refueling times, and are less affected by weather conditions than electric vehicles. Additionally, hydrogen fuel cells are efficient and can generate electrical energy, heat, and water through the reaction of hydrogen and oxygen.

Hydrogen cars can't be refuelled at home
Hydrogen fuel cell cars, such as the Hyundai Nexo and Toyota Mirai, are marketed as a greener alternative to traditional gasoline cars. However, one of the biggest disadvantages of hydrogen cars is that they cannot be refuelled at home, which is a significant drawback when compared to electric vehicles (EVs).
Unlike gasoline cars, which have a vast network of over 100,000 fuel stations across the nation, hydrogen cars are dependent on a limited number of high-pressure fuelling stations. In California, for instance, there are about 54 hydrogen refuelling stations, with most of them located in Los Angeles and San Francisco. While California has plans to expand its network, the current situation is that not all stations are operational at all times, and the recent closure of seven public hydrogen fuel stations by Shell has further reduced the refuelling options for hydrogen car owners.
The lack of convenient refuelling options means that hydrogen car drivers have to plan their journeys carefully and set off at odd hours to reach a fuelling station in time. This inconvenience, coupled with the small network of retail stations, often results in higher prices for hydrogen fuel. In late 2022, the California Hydrogen Business Council reported that the cost of hydrogen fuel in the state was between $10 and $17 per kilogram, which is significantly more expensive than gasoline.
To offset this disadvantage, some manufacturers, such as Honda, Hyundai, and Toyota, have offered incentives such as free hydrogen fuel for limited periods. However, once these incentives expire, drivers are faced with the high cost of refuelling. This uncertainty about the future of hydrogen fuelling infrastructure and the potential for high refuelling costs are significant drawbacks for consumers considering the switch to hydrogen fuel cell cars.
In summary, the inability to refuel hydrogen cars at home, coupled with the limited and unreliable hydrogen fuelling infrastructure, contributes to the challenges faced by hydrogen fuel cell technology in gaining widespread adoption.

Hydrogen fuel is not eco-friendly
Hydrogen fuel cell cars are often touted as the future of eco-friendly driving, but there are several reasons why this may not be the case. Firstly, hydrogen fuel is currently not produced in an eco-friendly manner. While hydrogen cars themselves produce zero tailpipe emissions, the production of hydrogen fuel can have an adverse impact on the environment, depending on how it is produced. If hydrogen is produced using renewable energy sources such as wind or solar power, then its carbon footprint is neutral. However, if it is produced using fossil fuels, it can have a negative impact on the climate, contributing to carbon emissions.
Secondly, hydrogen fuel cell cars face significant infrastructure challenges. As of 2024, there are limited hydrogen refueling stations available, with fewer than 60 stations in California, USA, for example. This lack of infrastructure can make it difficult and inconvenient for drivers to refuel their hydrogen cars, limiting their range and usability. The small number of retail stations also contributes to higher prices for hydrogen fuel, making it more expensive to operate a hydrogen car than a traditional gasoline or electric vehicle.
Thirdly, hydrogen fuel is more challenging and costly to store and transport than gasoline or diesel fuel. Hydrogen has a low energy content by volume, which means it requires high pressures, low temperatures, or chemical processes to be stored compactly. This makes the storage and transportation of hydrogen more energy- and labor-intensive, adding to the overall cost and environmental impact of using hydrogen fuel.
Lastly, hydrogen fuel cells themselves are expensive to replace. This adds to the overall cost of ownership of a hydrogen fuel cell car and may offset any environmental benefits when compared to traditional internal combustion engines or even electric vehicles. In conclusion, while hydrogen fuel cell cars offer certain advantages, such as zero tailpipe emissions and quick refueling times, the current realities of hydrogen fuel production, distribution, and infrastructure do not support the claim that they are truly eco-friendly.
