Hydrogen fuel cells are not widely used in cars due to a variety of factors, including the high cost of production and storage, safety concerns, and a lack of refuelling infrastructure. Hydrogen is highly flammable and requires specialized, expensive equipment for fuelling, which poses challenges for widespread adoption. Additionally, the process of converting electricity into hydrogen and back into electricity for powering the car results in significant energy loss, making it inefficient compared to electric vehicles. Despite some advantages of hydrogen fuel cells, such as long driving ranges, the dominance of electric vehicles and the falling prices of lithium-ion batteries have further contributed to the limited presence of hydrogen-powered cars on the road.

Hydrogen cars are expensive to produce, with high acquisition and operating costs
Hydrogen cars are not widely used, despite their promise as a clean transportation solution. One of the main reasons for this is the high cost of acquisition and operation.
The two mainstream hydrogen cars on sale in the US, the Toyota Mirai and Hyundai Nexo, start at around $50,000 and $60,000, respectively. These high prices are influenced by the demand for platinum, a precious metal that acts as a catalyst in electricity generation. While the amount of platinum needed for automotive fuel cells has decreased, it still contributes to the overall cost. Additionally, low production volumes play a role in the high acquisition costs, as industrialization in hydrogen car production is not yet fully developed.
The operating costs of hydrogen cars are also significant. The cost of hydrogen fuel is a major factor, with a kilogram of hydrogen costing around 14 euros. While a fuel cell car can travel about 100 kilometers on one kilogram of hydrogen, the high fuel price makes the overall cost per kilometer comparable to that of combustion vehicles. The inefficiency of hydrogen production further contributes to the high operating costs. Electrolysis, the process of extracting hydrogen from water, is highly inefficient and would create a substantial demand on the electricity grid if scaled up.
The challenges of storing hydrogen also contribute to the high operating costs. Hydrogen is very flammable and must be stored safely in gaseous form in thick-walled tanks to prevent uncontrolled reactions with oxygen. The specialized equipment required for fueling hydrogen cars is expensive, and the cost of building and maintaining hydrogen refueling stations is high, further impacting the operating costs for consumers.
Overall, the high acquisition and operating costs of hydrogen cars, influenced by factors such as the demand for expensive materials, low production volumes, fuel prices, and storage challenges, have made them less accessible and widely adopted compared to other vehicle types.

Hydrogen is highly flammable and difficult to store
Hydrogen is a highly flammable gas, and storing it safely is a challenge, especially in the event of a severe impact. Hydrogen tends to make metal brittle, and it has no natural source, so it must be manufactured. The usual way to produce it is by stripping it from hydrocarbons, which generates the same carbon emissions as fossil fuels. The alternative method of manufacturing it, electrolysis, is highly inefficient and would put huge demands on the electricity grid if scaled up.
Hydrogen vehicles use fuel cells, which require a lot of expensive materials. Hydrogen is stored in gaseous form in thick-walled tanks, which are designed to be safe. Numerous crash tests have validated the safety of this design, and hydrogen technology is tried and tested in a range of areas. However, the public may still be wary of driving with a pressurised tank of gas that could potentially leak and explode.
The cost of building and maintaining hydrogen refuelling stations is high, and there is ambiguity around when or if hydrogen cars will become mainstream, deterring potential investors and slowing the expansion of infrastructure. The scarcity of refuelling stations makes it difficult for consumers to refuel their vehicles, limiting the practicality and convenience of owning a hydrogen fuel car.
Hydrogen production is also inefficient, with much of the energy lost during electrolysis. The efficiency of the entire energy chain, from the production of electricity to the operation of the vehicle, is currently only half that of a battery-electric vehicle (BEV). However, hydrogen can be produced when there is an oversupply of electricity from renewable sources, and it is often a by-product in industrial processes, so it can be put to further use as a fuel.

Hydrogen fuel cells are inefficient compared to electric car batteries
Hydrogen fuel cell vehicles (HFCVs) are related to electric cars but differ in some key ways. One of the main challenges facing hydrogen fuel cell cars is the availability and clean production of hydrogen, as well as the utilisation of hydrogen as a power source. Hydrogen fuel cells are happiest at a steady power output, which is why they are suitable for backup power use. However, the power demands of an average car vary significantly, from a steady 15 kilowatts to keep a vehicle cruising on a flat road to 10-20 times that amount for maximum acceleration.
The production of hydrogen requires significant amounts of energy, so the way it is produced is critical to its environmental impact. Currently, 95% of hydrogen is generated from fossil fuel sources, which is a highly energy-intensive process. The efficiency of the entire energy chain—from the production of electricity to the operation of the vehicle—is currently only half that of a battery-electric vehicle (BEV). This is because, to power an HFCV, energy must move from wire to gas to wire, resulting in energy loss.
For every kilowatt of electricity supply, you get 800 watts of energy for a BEV but only 380 watts for an HFCV—less than half as much. This is a significant inefficiency, especially when considering the desire for a greener future. While hydrogen fuel cells offer a clean and energy-dense power source for the transport sector, the technology is currently expensive with limited supporting infrastructure.
In contrast, lithium-ion battery technology remains the most commercially advanced and practical solution for powering passenger and other lightweight electric vehicles. BEVs are also more flexible in terms of power output, making them more suitable for the varying power demands of an average car. Additionally, the cost of building and maintaining hydrogen refuelling stations is high, further exacerbated by the uncertainty around whether hydrogen cars will become mainstream, deterring potential investors and slowing the expansion of infrastructure.

Hydrogen refuelling infrastructure is scarce and expensive to build and maintain
Hydrogen fuel cell vehicles (HFCVs) are few and far between, and one of the main challenges faced by the industry is the lack of refuelling infrastructure. Hydrogen refuelling stations are scarce, and building and maintaining them is expensive. This is partly due to the high cost of hydrogen production and storage. The process of manufacturing hydrogen often involves significant energy loss, and the electricity required to produce it places a huge demand on the power grid.
Hydrogen refuelling stations require specialised and expensive equipment, which is a hurdle that electric vehicles (EVs) don't face to the same extent. Most EVs can be charged at home or work using cheap household electricity, whereas hydrogen refuelling stations require high electricity input and commercial sale. This means that the cost of refuelling an HFCV is similar to that of a petroleum-driven vehicle.
The scarcity of refuelling stations makes it difficult and impractical for consumers to refuel their vehicles, limiting the convenience of owning an HFCV. This, in turn, makes it difficult for HFCVs to become mainstream, creating ambiguity and uncertainty for potential investors, and slowing down the expansion of hydrogen refuelling infrastructure.
In addition to the challenges of building and maintaining a hydrogen refuelling network, the high cost of hydrogen fuel is a significant factor in the limited adoption of HFCVs. Hydrogen fuel is currently around 40% more expensive than gasoline and about 10% more expensive than EV batteries.
While hydrogen fuel cars hold promise as a clean transportation solution, the lack of refuelling infrastructure and the high costs associated with it are significant barriers to their widespread adoption.

Hydrogen production is inefficient, with much energy lost during electrolysis
Hydrogen fuel cell vehicles (HFCVs) are not widely used because of the inefficiencies in hydrogen production and energy loss during electrolysis.
Hydrogen is a highly flammable gas, and its safe storage is challenging. Hydrogen does not have a natural source and must be manufactured. The usual way to produce it is by stripping it from hydrocarbons, which generates carbon emissions. Electrolysis, the alternative method, is inefficient and demands a lot of electricity. If the local power grid relies on fossil fuels, electrolysis still produces carbon emissions.
The inefficiency of hydrogen production is a significant drawback for hydrogen fuel cells. The energy must be converted from electricity to hydrogen and then back to electricity to power a car, resulting in energy losses at each stage. This multi-step process is known as the Energy Vector Transition. For instance, consider 100 watts of electricity produced by a wind turbine. To power an HFCV, this electricity must first be converted into hydrogen, a process estimated to be 75% efficient, meaning 25% of the electricity is lost. The hydrogen then needs to be compressed, chilled, and transported to a hydrogen station, with a further loss of around 10% of energy. Once inside the vehicle, converting hydrogen into electricity to power the motor results in another loss of about 5% energy. Overall, only 38% of the original electricity is utilised, with 62% lost during the various stages of the energy chain.
The high cost of hydrogen production and storage is another barrier to the widespread adoption of hydrogen fuel cell cars. Hydrogen is currently expensive, impacting the operating costs of HFCVs. The cost of building and maintaining hydrogen refuelling stations is also high, further deterring potential investors and slowing down the expansion of the necessary infrastructure.
While hydrogen fuel cell technology has been evolving since its early inception in 1842, it has not yet overcome the challenges of inefficient hydrogen production and energy losses during electrolysis. These factors, along with the high costs associated with hydrogen fuel, contribute to the limited presence of hydrogen-powered cars on our roads today.
