In the race toward cleaner transportation, electric vehicles have dominated headlines and driveways alike. But while battery electric vehicles (BEVs) get most of the attention, another form of zero-emission technology continues to evolve in the background, hydrogen fuel cell vehicles (FCVs).
Hydrogen-powered cars have been called the “forgotten future” of clean transportation: efficient, powerful, and refuelable in minutes. So why aren’t we seeing more of them on the road? Let’s break down how they work, the automakers leading the charge, the pros and cons, and where hydrogen technology might fit into our future — before wrapping up with why your windshield still plays a vital role no matter what powers your car.
How Hydrogen Cars Work
Hydrogen-powered cars use a fuel cell, not a traditional combustion engine or large battery pack, to produce electricity on demand.
Here’s how the process works:
- Hydrogen is stored in tanks inside the vehicle, typically as compressed gas at very high pressure (around 10,000 psi).
- The hydrogen gas flows into the fuel cell stack, where it reacts with oxygen from the air in a chemical process known as electrolysis.
- This reaction generates electricity, which powers an electric motor to drive the wheels.
- The only byproduct? Water vapor and heat.
That means hydrogen fuel cell cars produce zero tailpipe emissions, just like fully electric vehicles. But instead of plugging in for hours to recharge, they refuel in three to five minutes, similar to filling up a gas tank.
Who’s Leading in Hydrogen Technology
While many automakers have invested heavily in electric vehicle development, a handful continue to pioneer hydrogen-powered models.
1. Toyota
Toyota remains the most recognizable name in hydrogen vehicles thanks to its Mirai, first launched in 2014. The second-generation Mirai offers a refined design, up to 400 miles of range, and zero emissions — though it’s still primarily sold in regions like California and Japan, where hydrogen fueling stations exist.
Beyond cars, Toyota is expanding hydrogen tech into trucks, buses, and industrial uses, including partnerships with companies like Kenworth for hydrogen-powered Class 8 trucks.
2. Hyundai
Hyundai’s Nexo is another prominent hydrogen fuel cell SUV, offering a range of around 380 miles and futuristic tech features. The Korean automaker has also been experimenting with hydrogen commercial vehicles under its “HTWO” brand, including buses and delivery trucks.
3. Honda
Honda was one of the earliest hydrogen adopters with its Clarity Fuel Cell, though production paused in 2021. The company has since announced plans to relaunch hydrogen-powered models using the next-gen CR-V platform by 2025, including plug-in hybrid fuel cell configurations.
4. BMW and Mercedes-Benz
European automakers are dipping back into hydrogen, too. BMW has tested its iX5 Hydrogen, while Mercedes continues exploring commercial hydrogen fleet options for its trucks and buses.
5. Cummins and Nikola Motors
In the commercial vehicle sector, Cummins and Nikola Motors are working on hydrogen-powered heavy-duty trucks. Cummins, known for diesel engines, is now investing heavily in hydrogen internal combustion engines (not just fuel cells) — which could revolutionize long-haul transport by offering clean power without full electrification.
Benefits of Hydrogen-Powered Vehicles
Hydrogen vehicles offer some unique advantages over both electric and gas-powered cars:
- Fast Refueling – It takes only a few minutes to fill a hydrogen tank, compared to 30 minutes or more for a fast-charging EV.
- Long Range – Many hydrogen models exceed 350–400 miles per tank, rivaling or surpassing most EVs.
- Zero Emissions – Hydrogen fuel cells emit only water vapor, making them environmentally friendly at the tailpipe.
- Consistent Performance – Unlike batteries, fuel cells don’t degrade as much over time or under extreme temperatures.
- Lighter Weight – Hydrogen systems can weigh less than massive EV batteries, improving handling and efficiency.
- Industrial Flexibility – Hydrogen can power not just cars but also buses, trucks, ships, and construction equipment, offering versatility across sectors.
The Downsides: Why Hydrogen Isn’t Widespread Yet
Despite their promise, hydrogen-powered cars face major hurdles:
- Limited Refueling Infrastructure
The biggest obstacle is infrastructure. There are only around 50 hydrogen fueling stations in the entire United States — nearly all in California. Without widespread availability, adoption can’t scale. - High Production Costs
Producing “green hydrogen” — hydrogen created from renewable energy instead of fossil fuels — remains expensive and energy-intensive. - Complex Storage and Distribution
Hydrogen must be stored at very high pressure and kept stable, which requires specialized tanks, pipelines, and handling procedures. - Vehicle Cost
The technology behind fuel cells and hydrogen storage is costly, which makes hydrogen cars more expensive than traditional hybrids or EVs. - Public Awareness and Support
Many consumers simply don’t know much about hydrogen vehicles, leading to lower demand and slower development.
Hydrogen vs. Electric vs. Hybrid Vehicles
| Category | Hydrogen Fuel Cell | Battery Electric | Hybrid |
| Fuel Source | Hydrogen gas | Electricity from battery | Gas + Electricity |
| Emissions | Water vapor only | None | Reduced vs. gas-only |
| Refueling Time | 3–5 minutes | 30+ minutes (fast charger) | 5 minutes |
| Range | 350–400 miles | 250–400 miles (avg) | 400–600 miles |
| Infrastructure | Very limited | Expanding rapidly | Widespread |
| Maintenance | Moderate | Low | Moderate |
| Best Use Case | Fleets, long-distance, heavy-duty | City driving, home charging | General-purpose, transitional |
In short, hydrogen cars combine the range and convenience of gasoline with the clean operation of EVs, but until refueling infrastructure grows, electric and hybrid vehicles will remain more practical for most drivers.
Current and Upcoming Innovations
Hydrogen technology is far from stagnant — in fact, it’s accelerating:
- Toyota’s Hydrogen Combustion Engines – Toyota is testing hydrogen-fueled internal combustion engines that run on hydrogen instead of gasoline, potentially preserving the performance feel of traditional engines with zero carbon output.
- Cummins Hydrogen Engines – Cummins has unveiled both hydrogen ICEs (internal combustion engines) and fuel cell systems for trucks and buses, offering flexible options for commercial fleets.
- Hydrogen Electrolyzers – Advances in renewable-powered electrolyzers are lowering the cost of producing green hydrogen.
- Heavy-Duty Applications – Companies like Nikola, Hyundai, and Hyzon Motors are pushing hydrogen semi-trucks into production, ideal for long routes where charging large batteries isn’t practical.
- Aviation and Marine Hydrogen – Airbus and several marine tech companies are developing hydrogen solutions for planes and ships, extending the clean-energy horizon far beyond cars.
As costs drop and refueling stations expand, hydrogen may carve out a crucial niche in the global clean transport mix.
No Matter What Powers Your Vehicle, Your Windshield Matters
Whether your car runs on hydrogen, electricity, gasoline, or a hybrid system, one thing stays the same, your windshield is critical to your safety and driving experience. It supports your vehicle’s structure, protects you from debris, and enables key ADAS (Advanced Driver Assistance Systems) features like lane-keeping and automatic braking.
If your windshield is chipped, cracked, or damaged, getting it repaired or replaced quickly ensures that your car, no matter how it’s powered, stays safe and roadworthy.That’s where Glass.net can help.
