Electric vs Hydrogen
The automotive industry is at the forefront of a massive technological revolution, spurred by the global need to combat climate change and reduce our carbon footprint. Traditional combustion engines are being phased out, making way for clean energy alternatives. Two technologies are currently leading the charge: Electric Vehicles (EVs) and Hydrogen Fuel Cell Vehicles (FCEVs). But which one will dominate the future of automotive fuel? In this blog, we explore the strengths, weaknesses, infrastructure challenges, costs, and environmental impacts of EVs and hydrogen vehicles to determine if one holds a clear advantage.
The Need for Change
The UK, like many other countries, has announced its intent to ban the sale of new petrol and diesel cars by 2030 as part of its net-zero emissions strategy. This shift has accelerated investments in clean automotive technologies. However, as EVs gain momentum, hydrogen fuel cell vehicles are emerging as a potential alternative, especially for heavy-duty transport.
While both technologies offer significant reductions in emissions, they come with their own set of challenges and advantages. Let’s take a closer look.
How Do EVs and Hydrogen Fuel Cell Vehicles Work?
Electric Vehicles (EVs)
Electric Vehicles are powered by lithium-ion batteries. These batteries store energy, which powers an electric motor, driving the vehicle. EVs can be charged at home or public charging stations.
How it works:
-
The battery stores electricity.
-
Electricity powers the motor.
-
The motor moves the wheels, providing propulsion.
Key Advantage: EVs have zero tailpipe emissions and are highly efficient.
Hydrogen Fuel Cell Vehicles (FCEVs)
FCEVs use hydrogen gas to generate electricity through a chemical process in a fuel cell. The only byproduct of this process is water vapour.
How it works:
-
Hydrogen is stored in high-pressure tanks.
-
In the fuel cell, hydrogen reacts with oxygen.
-
The chemical reaction generates electricity, which powers the motor.
Key Advantage: FCEVs can be refuelled quickly and offer long driving ranges, similar to petrol or diesel vehicles.
Pros and Cons of EVs and Hydrogen Vehicles
| Feature | Electric Vehicles (EVs) | Hydrogen Vehicles (FCEVs) |
|---|---|---|
| Emissions | Zero emissions at the tailpipe. | Zero emissions; water vapour only. |
| Efficiency | 85-90% efficient in energy use. | 40-60% efficient in energy use. |
| Infrastructure | Growing network of charging stations. | Limited hydrogen refuelling stations. |
| Refuelling/Charging Time | 20-60 minutes (fast chargers). | 3-5 minutes. |
| Range | 150-300 miles (higher with larger batteries). | 300-400 miles. |
| Cost | Batteries are expensive but dropping. | Hydrogen production is costly. |
| Maintenance | Fewer moving parts, minimal maintenance. | Complex fuel cells increase costs. |
Infrastructure Challenges
One of the major differences between EVs and hydrogen fuel cell vehicles lies in their infrastructure requirements. Let’s break it down:
Electric Vehicles
-
EVs can be charged at home, workplaces, or public stations.
-
The UK has made significant investments in charging networks, with over 40,000 public chargers as of 2024.
-
Fast-charging technology continues to improve, with rapid chargers offering 80% charge in under 30 minutes.
Hydrogen Fuel Cell Vehicles
-
Hydrogen refuelling stations are far less common. As of 2024, the UK has fewer than 20 operational stations.
-
Hydrogen infrastructure is costly to build and maintain.
-
Refuelling is quick (3-5 minutes), but without widespread stations, FCEVs remain impractical for most consumers.
Infrastructure Verdict: EVs currently have a clear advantage, thanks to their rapidly expanding charging network.
Cost Comparison: EVs vs Hydrogen Vehicles
The cost of ownership plays a key role in determining the future of clean vehicles. Here’s a quick breakdown:
| Cost Factor | Electric Vehicles | Hydrogen Vehicles |
| Upfront Cost | £30,000 - £50,000 (falling). | £60,000+ (currently higher). |
| Refuelling/Charging | £10-£20 per full charge. | £50-£70 per refuel. |
| Maintenance | Lower due to fewer components. | Higher due to fuel cell tech. |
While hydrogen vehicles are currently more expensive, economies of scale and advancements in green hydrogen production could lower costs in the future. However, EVs are already benefiting from decreasing battery costs, making them more accessible.
Environmental Impact
Both EVs and hydrogen vehicles are cleaner alternatives to fossil fuels, but they come with environmental trade-offs:
Electric Vehicles
-
EVs have zero tailpipe emissions.
-
Battery production, however, relies on lithium, cobalt, and other minerals, which require intensive mining.
-
Efforts are underway to improve battery recycling to reduce environmental impact.
Hydrogen Vehicles
-
Hydrogen can be produced through various methods:
-
Grey hydrogen: Made from natural gas, emits carbon dioxide.
-
Green hydrogen: Produced using renewable energy, zero emissions.
-
-
Currently, over 95% of hydrogen is grey hydrogen. Transitioning to green hydrogen is critical to reducing emissions.
Environmental Verdict: EVs have a smaller footprint today, but advancements in green hydrogen could make FCEVs equally sustainable.
Future Outlook: Can Both Technologies Coexist?
Rather than a competition, it’s likely that EVs and hydrogen vehicles will coexist, serving different segments of the market:
-
EVs: Ideal for short to medium commutes, urban driving, and passenger cars.
-
FCEVs: Better suited for heavy-duty transport, long-haul trucking, and industries requiring quick refuelling.
Market Projections
According to industry forecasts, electric vehicles are expected to dominate the passenger car market, while hydrogen will gain traction in commercial transport. The graph below illustrates this trend:

Conclusion: The Road Ahead
The future of automotive fuel will be shaped by technological advancements, infrastructure development, and consumer demand. For now, electric vehicles are leading the charge, thanks to their efficiency, growing infrastructure, and falling costs. However, hydrogen fuel cell vehicles remain a promising alternative, particularly for heavy-duty and long-distance applications.
The real solution may not be a single technology but a combination of both, working together to create a cleaner, greener future for the automotive industry.
Final Thought:
As a consumer, the choice between EVs and hydrogen vehicles comes down to your specific needs and the availability of infrastructure. Both technologies represent a monumental step toward sustainable transport – and that’s something we can all get behind.
