Hydrogen cars are sometimes presented as an alternative to battery electric vehicles. How do they actually compare?
The Basics
Battery Electric (BEV)
Hydrogen Fuel Cell (FCEV)
Quick Comparison
| Factor | Battery Electric | Hydrogen |
|---|---|---|
| Range | 200-400 miles | 300-400 miles |
| Refuelling time | 20-40 mins (rapid) | 5 mins |
| Running cost | Low | High |
| Infrastructure | Widespread | Very limited |
| Vehicle cost | Moderate | Very high |
| Efficiency | ~85-90% | ~30-40% |
| Home refuelling | Yes | No |
The Efficiency Problem
Energy Conversion
Battery EV:
Overall efficiency: ~85%
Hydrogen:
Overall efficiency: ~30%
The maths: 3x more energy required to drive the same distance on hydrogen.
Infrastructure Reality
Charging Points (BEV)
| Type | UK Count |
|---|---|
| Public chargers | 70,000+ |
| Rapid chargers (50kW+) | 15,000+ |
| Home charging capable | Millions of homes |
Hydrogen Stations (FCEV)
| UK Status | Count |
|---|---|
| Operating stations | ~15 |
| Planned stations | ~20 |
| Coverage | Very limited |
Reality: You can charge a BEV almost anywhere. Hydrogen stations are extremely rare.
Costs Compared
Vehicle Prices
| Vehicle Type | Example | Price |
|---|---|---|
| Battery EV | Hyundai Ioniq 5 | £45,000 |
| Hydrogen FCEV | Hyundai Nexo | £70,000 |
| Hydrogen FCEV | Toyota Mirai | £65,000 |
Running Costs
| Cost Type | BEV | Hydrogen |
|---|---|---|
| Home charging | 7-24p/kWh | N/A |
| Public charging | 40-70p/kWh | N/A |
| Hydrogen (per kg) | N/A | £10-15 |
| Cost per mile | 4-10p | 15-20p |
Hydrogen is 2-4x more expensive per mile than battery electric.
Maintenance
| Factor | BEV | Hydrogen |
|---|---|---|
| Servicing | Minimal | Moderate |
| Complexity | Low | Higher (fuel cell system) |
| Parts availability | Good | Limited |
Practical Considerations
For Daily Driving
| Factor | BEV | Hydrogen |
|---|---|---|
| Home charging | Yes | No |
| Refuelling convenience | Easy | Very difficult |
| Range for commute | Excellent | Excellent |
| Running costs | Low | High |
Winner: BEV — Home charging transforms daily use.
For Long Journeys
| Factor | BEV | Hydrogen |
|---|---|---|
| Refuelling time | 20-40 mins | 5 mins |
| Station availability | Good | Extremely limited |
| Route flexibility | Good | Must plan around stations |
| Cost | Moderate | High |
Winner: BEV — Despite faster refuelling, hydrogen stations barely exist.
Where Hydrogen Makes Sense
Not Passenger Cars (Currently)
For personal transport, hydrogen doesn't make sense:
Heavy Transport (Potentially)
Hydrogen may suit:
Why: These vehicles need range/weight ratios that batteries struggle with, and can refuel at depots (limited stations acceptable).
Why Do People Talk About Hydrogen?
Legitimate Interest
Lobbying
Some hydrogen enthusiasm comes from:
Misunderstanding
Media coverage sometimes implies parity that doesn't exist in practice.
Future Outlook
Battery EVs
| Trend | Direction |
|---|---|
| Range | Increasing |
| Charging speed | Faster |
| Prices | Falling |
| Infrastructure | Expanding rapidly |
| Mainstream adoption | Happening now |
Hydrogen Cars
| Trend | Direction |
|---|---|
| Range | Good but static |
| Refuelling | Fast but irrelevant without stations |
| Prices | Still high |
| Infrastructure | Barely growing |
| Mainstream adoption | Not foreseeable |
Expert Consensus
What Industry Leaders Say
Volkswagen: "Hydrogen for cars makes no sense."
Tesla: (Obviously promotes BEVs)
Toyota: Still pursuing hydrogen but scaling back
Hyundai: Making both but EVs dominating sales
What Analysts Predict
| Segment | 2030 Prediction |
|---|---|
| Passenger cars | 95%+ BEV, minimal hydrogen |
| Light trucks/vans | 90%+ BEV |
| Heavy trucks | Split — BEV growing, hydrogen niche |
| Buses | Mostly BEV, some hydrogen |
Summary
| Factor | Battery EV | Hydrogen |
|---|---|---|
| Buy today? | Yes | No (for most) |
| Practical? | Yes | No (UK) |
| Cost-effective? | Yes | No |
| Future-proof? | Yes | Uncertain |
| Recommendation | Buy | Wait and see |
The Bottom Line
For passenger cars, battery electric wins on every practical measure:
Hydrogen for cars is a solution looking for a problem. The problem (transport emissions) has already been solved more efficiently by batteries.
When hydrogen might matter:
If you're considering which technology to adopt, the answer is clear: buy a battery EV. Hydrogen passenger cars are a niche experiment that may never become mainstream.
