Hydrogen fuel cell cars have been touted as the future of the automotive industry, but they have not yet become mainstream. There are a few reasons for this. Firstly, the cost of hydrogen fuel is high, with the total cost of ownership for hydrogen cars being around 40% more than for gasoline vehicles and about 10% more than electric vehicles (EVs). Additionally, there is a lack of infrastructure for hydrogen cars, with very few refuelling stations available to consumers. The cost of building and maintaining these stations is also high, and there is uncertainty around whether hydrogen cars will become mainstream, deterring potential investors. Another barrier is the high cost of hydrogen production and storage, as it currently requires a significant amount of energy to produce hydrogen gas, often using fossil fuels. While hydrogen fuel cell technology continues to evolve and receive funding, it has not yet become widely available for everyday use.

What You'll Learn
Hydrogen fuel cells are inefficient compared to battery electric vehicles
Hydrogen fuel cell vehicles (HFCVs) are widely considered safe and environmentally friendly. However, they are inefficient compared to battery electric vehicles (EVs) due to various factors, including production, infrastructure, and cost.
Firstly, hydrogen production for HFCVs often relies on fossil fuels, resulting in CO2 emissions. In contrast, EVs can be powered by renewable sources, reducing their carbon footprint. The process of obtaining hydrogen gas through electrolysis is energy-intensive, and the current lack of commercially viable methods for producing hydrogen on a large scale using renewable energy sources, such as solar or wind power, further contributes to the inefficiency of HFCVs.
Secondly, the infrastructure for HFCVs is limited. The scarcity of refuelling stations makes it challenging for HFCV owners to refuel their vehicles, impacting the convenience and practicality of owning such a car. The high cost of building and maintaining hydrogen refuelling stations, coupled with the uncertainty surrounding the mainstream adoption of hydrogen cars, discourages potential investors and slows down the expansion of the necessary infrastructure.
Additionally, the cost of HFCVs is a significant factor in their inefficiency. The high cost of producing and storing hydrogen, along with the expensive materials required for containment due to its volatile nature, makes HFCVs less accessible to consumers. In contrast, advancements in battery technology for EVs have led to greater affordability, and the increasing availability of charging infrastructure has made EVs more attractive to consumers.
Furthermore, the lack of supportive policies and regulations in many countries, except those with strong government support like Japan and Germany, hampers the growth of the hydrogen fuel car market. Government incentives, such as those provided in Japan and Germany, are crucial in stimulating demand and encouraging the transition to hydrogen fuel cars.
While HFCVs offer quick refuelling times compared to EVs, the challenges related to production, infrastructure, cost, and government support contribute to their inefficiency compared to EVs. As a result, the future of passenger vehicles seems to be leaning towards battery-electric options.

Hydrogen fuel cells are expensive to produce and store
Hydrogen fuel cell cars have been described as the "vehicle of the future", but their high cost has limited their uptake. The Hyundai Nexo and Toyota Mirai are the only fuel cell vehicles currently on sale, and they come with a high price tag of at least £50,000. The slow sales of these cars can be attributed in part to the limited refuelling infrastructure, as consumers are deterred by the scarcity of refuelling stations. This, in turn, makes it difficult for companies to justify building and maintaining more refuelling stations, creating a cycle that hinders the expansion of the hydrogen fuel cell car market.
The production of hydrogen fuel cells is an energy-intensive process, which contributes to their high cost. Hydrogen gas is obtained through electrolysis, which requires a significant amount of energy. Additionally, the storage and transportation of hydrogen pose further challenges due to its low volumetric energy density and highly volatile and reactive nature. This means that complex engineering and materials are required to keep it contained, adding to the overall expense.
The lack of supportive policies and regulations in many countries also hampers the growth of the hydrogen fuel car market. While some countries, such as Japan and Germany, have provided financial incentives for purchasing hydrogen fuel cars and invested in the development of refuelling infrastructure, others have not shown the same level of commitment. The UK, for example, has been criticised for its lack of focus on hydrogen filling stations and infrastructure, creating uncertainty for car manufacturers and potential customers alike.
In conclusion, the high cost of producing and storing hydrogen fuel cells, coupled with the limited refuelling infrastructure and lack of supportive policies, are significant barriers to the widespread adoption of hydrogen fuel cell cars. While hydrogen fuel cell technology has been touted as a promising alternative to electric vehicles, addressing the challenges of cost and infrastructure will be crucial for its success in the automotive industry.

Hydrogen fuel cells are not widely available
One significant obstacle is the high cost of hydrogen fuel cells. The current cost of purchasing a hydrogen fuel cell vehicle is relatively high, with prices starting at around £50,000 or more. This makes them less accessible to the average consumer and hinders their widespread adoption. Additionally, the cost of building and maintaining hydrogen refuelling stations is also substantial, further deterring potential investors and slowing down the expansion of the necessary infrastructure.
Another critical factor is the availability and production of hydrogen fuel. Currently, most hydrogen is produced using fossil fuels, which defeats the purpose of reducing carbon emissions. While hydrogen fuel cells only emit water vapour, the process of producing hydrogen can lead to pollution and contributes to the overall carbon footprint. The production of hydrogen using renewable energy sources, such as solar or wind power, is not yet commercially viable on a large scale, and the storage and transportation of hydrogen are costly and complex due to its volatile and reactive nature.
Furthermore, the infrastructure for supplying hydrogen to retail outlets and refuelling stations is lacking. The number of hydrogen refuelling stations is limited, and they are often located far from each other, making it inconvenient for consumers to refuel their vehicles. This scarcity of refuelling stations, coupled with the high cost of building and maintaining them, creates a chicken-and-egg problem, where consumers are hesitant to adopt hydrogen fuel cell vehicles due to the limited refuelling options, and investors are reluctant to invest in more stations due to the uncertain future of hydrogen cars.
Additionally, some experts argue that the focus on electric vehicles (EVs) by governments and automakers has contributed to the lack of widespread availability of hydrogen fuel cells. EVs have gained significant traction in recent years due to advancements in battery technology, greater affordability, and the increasing availability of charging infrastructure. Governments have also directed their support and funding towards EVs, with many countries implementing policies and incentives to promote their adoption. This has resulted in a shift in attention away from hydrogen fuel cells, with some car manufacturers discontinuing their hydrogen-powered models due to slow sales.
Lastly, there are technological challenges associated with hydrogen fuel cells. For instance, the process of converting electricity into hydrogen and then back into electricity to power a car, known as the Energy Vector Transition, leads to energy losses at each stage of the process, resulting in overall low efficiency. In contrast, electric vehicles can utilise existing infrastructure and deliver electricity directly to the vehicle, bypassing the need for energy conversion and improving overall efficiency.

Hydrogen fuel cells are not widely understood
Hydrogen fuel cells are a zero-emission power source that uses hydrogen to generate electricity, with water vapour as the only emission. This technology is distinct from electric vehicles (EVs), which rely on batteries that can be charged via existing infrastructure. Hydrogen fuel cells, on the other hand, require specialised refuelling stations, which are currently scarce and expensive to build and maintain. This lack of infrastructure makes owning a hydrogen-powered vehicle less practical and convenient.
The process of producing hydrogen fuel cells is also not widely understood. Hydrogen gas is primarily obtained through electrolysis, which requires a significant amount of energy. Currently, most hydrogen is produced using fossil fuels, which is counterproductive to the goal of reducing carbon emissions. While it is possible to produce hydrogen using renewable energy sources, such as solar or wind power, this method is not yet commercially viable on a large scale. The storage and transportation of hydrogen are also challenging due to its low volumetric energy density and volatile nature, further complicating safety measures.
The high cost of hydrogen fuel cells is another factor that may be off-putting to consumers. In the UK, for example, the Hyundai Nexo and Toyota Mirai, the only fuel cell vehicles currently on sale, cost at least £50,000. Additionally, the cost of refuelling these vehicles is high, with an average price of $16/kg for hydrogen fuel in California.
Despite these challenges, some companies remain committed to hydrogen fuel cell technology. Toyota, for example, has produced an internal combustion engine that runs on hydrogen and is currently undergoing trials. BMW and Toyota have also announced a collaboration, with plans to release a BMW hydrogen production car in 2028. While hydrogen fuel cells may not be the primary power source for passenger vehicles in the near future, they may still have a role to play in other applications, such as long-haul trucks, aviation, and heavy goods vehicles, where their refuelling time advantages and efficiency can be fully utilised.

Hydrogen fuel cells are not widely supported by governments
In addition, the production and storage of hydrogen fuel are costly and energy-intensive processes. Hydrogen is currently produced mostly from fossil fuels, which undermines the goal of reducing carbon emissions. While using renewable energy sources like solar or wind power is more environmentally friendly, it is not yet commercially viable on a large scale. The transportation of hydrogen is also challenging due to its volatile and reactive nature, requiring complex engineering and materials to ensure safety.
The lack of supportive policies and regulations in many countries has further hampered the growth of the hydrogen fuel cell car market. While some countries like Japan and Germany have successfully adopted hydrogen fuel cars due to strong government support and financial incentives, other countries like the UK have been criticised for a lack of commitment to hydrogen infrastructure.
The automotive industry's focus on electric vehicles (EVs) and advancements in battery technology have also drawn attention and investment away from hydrogen fuel cells. EVs have gained popularity due to their decreasing costs, improving battery technology, and the growing availability of charging infrastructure. As a result, governments and automakers have prioritised EVs over hydrogen fuel cells in their efforts to reduce carbon emissions and meet sustainability goals.
The inefficiency of hydrogen fuel cells compared to EVs is another factor. The process of converting electricity into hydrogen and then back into electricity to power a car results in significant energy loss, making it less efficient than the direct use of electricity in EVs. This inefficiency, combined with the high energy demand of hydrogen technology, has made EVs a more attractive option for governments and consumers alike.
