What You'll Learn
Hydrogen fuel cells are inefficient
Additionally, hydrogen fuel produced from fossil fuels creates "grey" hydrogen, which produces a lot of CO2, or "blue" hydrogen, which captures and stores CO2 but does not eliminate it. Only electrolyzing hydrogen from water using electricity from renewable sources makes the fuel entirely green. However, this process has already lost more than half of its energy before it gets to the car due to energy loss from the electrolysis and transportation of hydrogen.
Furthermore, hydrogen fuel cells may not be workable for heavier vehicles like vans or trucks, as they require very large batteries. While hydrogen may be more suitable for these larger vehicles than electric batteries, the carbon footprint of hydrogen vehicles is similar to that of electric vehicles when both are charged using renewable electricity.
The inefficiency of hydrogen fuel cells is a significant drawback, especially when compared to the efficiency of electric vehicles. Electric vehicles have a more efficient power-to-vehicle-drive energy chain, and the batteries in these vehicles typically only waste about 5% of the energy during charging. This, coupled with the rising sales and adoption of electric vehicles, makes it challenging for hydrogen cars to overtake.

Hydrogen is difficult to source
Secondly, there is a limited infrastructure for hydrogen fuelling stations, which makes it inconvenient and challenging to refuel hydrogen fuel cell cars. As of 2020, California, which has the most comprehensive hydrogen fuelling infrastructure in the United States, had a network of 75 stations expected to serve only 17,000 to 24,000 hydrogen vehicles in 2020. In contrast, there were already half a million plug-in electric cars on the roads in California. The limited number of hydrogen fuelling stations can lead to supply interruptions, as was the case in Northern California in 2020 when an explosion at a hydrogen supply facility cut off supply to 9 out of the area's 11 fuelling stations.
The lack of widespread hydrogen fuelling infrastructure also limits the feasibility of long-distance travel with hydrogen fuel cell cars. For example, as of 2020, it was not possible to travel from Los Angeles to Tucson and back with a hydrogen-powered car due to the lack of fuelling stations along the route. This restricted mobility can be a significant disadvantage for consumers considering hydrogen fuel cell cars.
Furthermore, the cost of hydrogen-powered cars is currently very high, with prices exceeding £60,000 for some models. This high cost can be a barrier for many consumers considering purchasing a hydrogen fuel cell car.
While there are ongoing efforts to expand the hydrogen fuelling infrastructure and increase the production of hydrogen fuel cell cars, the current challenges in sourcing hydrogen for these vehicles remain a significant obstacle to their widespread adoption.

Hydrogen fuel cells are expensive
Hydrogen fuel cell cars are expensive. This is due to a variety of factors, including the high cost of the technology, the limited infrastructure for refuelling, and the relatively small-scale production of hydrogen fuel cell vehicles.
Firstly, the technology itself is costly. Hydrogen fuel cells are complex systems that require a range of expensive materials and components, such as platinum catalysts and carbon fibre pressure tanks. These materials are not only expensive to source but also to manufacture and assemble, driving up the overall cost of the vehicle.
Secondly, the infrastructure for refuelling hydrogen fuel cell cars is still being developed and is currently limited. As of 2020, California, which has led the way in tackling vehicle emissions, had only 75 stations expected to serve 17,000 to 24,000 hydrogen vehicles. In comparison, there were already half a million plug-in electric cars on the roads in the state. The limited refuelling infrastructure increases the cost of running a hydrogen fuel cell vehicle, as it can lead to supply interruptions and higher prices for hydrogen fuel.
Additionally, the small-scale production of hydrogen fuel cell vehicles contributes to their high cost. As a relatively new technology, these vehicles are typically produced in limited quantities, with a focus on prototyping and concept development. This means that manufacturers cannot take advantage of economies of scale in the same way that electric vehicle producers can. As a result, the cost of producing each vehicle remains high, and these costs are passed on to the consumer.
It is worth noting that as the market for hydrogen fuel cell vehicles grows, costs are expected to decrease. However, this is dependent on achieving larger-scale manufacturing and infrastructure development, which will require significant investment and time.
In summary, hydrogen fuel cell cars are currently expensive due to the high cost of technology, limited refuelling infrastructure, and small-scale production. While costs may decrease as the market grows, it will require a significant shift in infrastructure and production to make hydrogen fuel cell vehicles a more affordable option for consumers.

Hydrogen fuel cell cars are unsafe
The production of hydrogen fuel is also a safety concern. Currently, most hydrogen is produced by reforming natural gas, which is a polluting process. Hydrogen can be produced using renewable energy, but this is not yet common practice.
The distribution of hydrogen fuel is another issue. There is currently a very limited network of hydrogen refueling stations, and these stations are expensive to build and operate. This means that hydrogen car owners may struggle to find a place to refuel their vehicles, and a single supply interruption can cause a lengthy shortage.
In addition to safety concerns, hydrogen fuel cell cars have other drawbacks. They are very expensive to buy, and the technology is new and unproven, so early adopters may be taking a risk. Hydrogen fuel cell cars are also facing strong competition from electric vehicles, which are becoming increasingly popular and have the advantage of being able to be charged at home or at work.
While hydrogen fuel cell cars have some promising eco-friendly credentials, the safety concerns, high costs, and competition from electric vehicles mean that they may struggle to become a mainstream choice for consumers.

Hydrogen fuel cell infrastructure is lacking
Since 2012, only about 8,000 hydrogen-powered cars have been sold in the US, and these are limited to California, due to the lack of hydrogen fuelling stations in other states. Even in California, the hydrogen fuelling network has been described as "pricey and unreliable". An explosion at a hydrogen supply facility in Santa Clara in 2019 caused a supply shortage that lasted several months, affecting fuelling stations across Northern California and leading to furious owners having to race to reach fuelling stations.
In contrast, there are already half a million plug-in cars on the roads in California, and electric vehicles are entering the mainstream. Globally, Japan and Germany are leaders in hydrogen fuelling infrastructure, with Germany aiming for 400 stations by 2025. However, the US is lagging, and the thin fuelling network in California has proven to be a significant drawback for fuel cell car owners.
The lack of infrastructure is a key barrier to wider adoption of fuel cell cars, and until this is addressed, it is unlikely that hydrogen fuel cell cars will become a common sight on our roads.

Frequently asked questions
Hydrogen fuel cell cars are not a good alternative to electric cars because they are expensive, and there is a thin fueling network for them.
Electric cars are more efficient than hydrogen fuel cell cars because they lose only 5% of their energy in the grid, whereas hydrogen fuel cells lose double the amount of energy.
Hydrogen fuel cell cars have a lower carbon footprint than electric vehicles, with 2.7g of carbon dioxide per kilometre compared to 20.9g. However, this comparison assumes that hydrogen is produced using renewable energy, which is not always the case.
Hydrogen fuel cell cars can be refueled quickly and easily, similar to traditional gas and diesel vehicles. Electric cars, on the other hand, often need to be charged overnight at home or during the day at work, and public charging stations are not always readily available.
Hydrogen fuel cell cars are currently very expensive to buy, with prices sitting north of £60,000. However, it is expected that fuel cell costs will decrease if the market grows and manufacturing becomes more efficient.
