The biggest problem with hydrogen cars is the near-total lack of refueling infrastructure. As of 2024, there were only 54 open retail hydrogen stations in the entire United States, with the vast majority clustered in California. For comparison, there are roughly 150,000 gas stations and over 60,000 public EV charging locations across the country. Without places to fill up, hydrogen cars remain impractical for almost every American driver.
But infrastructure isn’t the only challenge. It connects to a web of other problems, from the economics of hydrogen fuel to the environmental reality of how it’s produced, that together explain why hydrogen passenger cars have struggled to gain traction.
A Refueling Network That Barely Exists
You can only drive a hydrogen car where hydrogen stations exist, and right now that means California or essentially nowhere. Those 54 retail stations are not evenly spread across even that one state. More than 20 additional stations are in various stages of planning or construction, but progress has been slow. Honda’s 2026 CR-V e:FCEV, one of the only hydrogen passenger vehicles currently available in the U.S., can only be leased in California, and eligibility depends on your proximity to an approved fueling station.
The situation is getting worse, not better. In 2024, Shell permanently closed all seven of its hydrogen light-duty passenger fueling stations in California, citing “hydrogen supply complications and other external market factors.” Stations shut down in Berkeley, Sacramento, San Francisco, and San Jose. When a major energy company walks away from the market entirely, it signals deep structural problems beyond a simple chicken-and-egg dynamic between cars and stations.
This creates a vicious cycle. Automakers won’t mass-produce hydrogen cars without a fueling network. Companies won’t build stations without enough cars on the road to make them profitable. And consumers won’t buy a car they can’t reliably refuel. Electric vehicles broke through this loop because charging infrastructure could piggyback on the existing electrical grid. Hydrogen has no equivalent shortcut.
Hydrogen Fuel Is Expensive
Even where stations exist, hydrogen is costly. Retail hydrogen prices have hovered around $30 to $36 per kilogram in California, and a typical fuel cell vehicle uses about one kilogram per 60 to 70 miles. That works out to roughly $0.43 to $0.60 per mile in fuel costs alone. Gasoline in a conventional car costs around $0.10 to $0.15 per mile, and electricity for an EV costs roughly $0.04 to $0.06 per mile when charged at home.
The high price reflects the entire supply chain: producing hydrogen, compressing or liquefying it for transport, trucking it to stations, and storing it at extremely high pressure. Each step adds cost that doesn’t exist for electricity, which flows through wires already running to nearly every building in the country.
Most Hydrogen Isn’t Clean
Hydrogen cars produce zero tailpipe emissions. Water vapor is the only thing that comes out of the exhaust. But the environmental story starts at the production facility, not the tailpipe, and it’s far less encouraging.
Over 95% of the world’s hydrogen is “grey” hydrogen, produced from fossil fuels through steam reforming of natural gas or coal gasification. This process generates 10 to 19 tons of CO2 for every ton of hydrogen produced. When you account for these upstream emissions, a hydrogen car running on grey hydrogen can have a carbon footprint comparable to or worse than a modern gasoline hybrid.
“Green” hydrogen, made by splitting water using renewable electricity, produces no CO2 during production. It represents the environmental promise of the technology. But it accounts for less than 0.1% of global hydrogen production today. Green hydrogen costs significantly more than grey, and scaling it up requires enormous amounts of renewable electricity. Many energy analysts point out that using that same renewable electricity to directly charge battery EVs would be roughly three times more efficient, since converting electricity to hydrogen and back to electricity in a fuel cell loses energy at every step.
The Efficiency Gap
This efficiency difference is a fundamental physics problem, not a temporary engineering limitation. When you charge a battery EV, about 80 to 90% of the electrical energy from the grid ends up moving the car. With hydrogen, the chain looks different: electricity powers an electrolyzer to make hydrogen (losing about 30% of energy), the hydrogen is compressed or liquefied for transport (losing another 10 to 15%), and the fuel cell converts it back to electricity in the car (losing another 40 to 50%). End to end, only about 25 to 35% of the original electrical energy reaches the wheels.
This means a hydrogen fuel system needs roughly two to three times more renewable electricity to move a car the same distance as a battery EV. In a world where clean electricity is still scarce and expensive to build, that inefficiency matters enormously.
Storage and Engineering Complexity
Hydrogen is the lightest element in the universe, which makes storing enough of it to give a car reasonable range a serious engineering challenge. Fuel cell vehicles carry hydrogen compressed to either 5,000 psi or 10,000 psi in reinforced tanks. For context, a typical car tire holds about 32 psi. These tanks are built with carbon fiber composites and must meet federal crash safety standards. They’re equipped with sensors that shut down the system if a leak is detected and pressure relief devices that vent the tank safely during a fire.
The tanks are safe by engineering standards, but they’re expensive to manufacture and add significant cost to the vehicle. They also take up considerable space, which limits design flexibility for automakers. And the high-pressure infrastructure required at every point in the supply chain, from production to transport to the refueling station, adds cost and complexity that battery EVs simply don’t face.
Where Hydrogen Might Still Make Sense
None of this means hydrogen is useless as a fuel. Its advantages over batteries become real in applications where weight matters more and refueling time is critical: long-haul trucking, shipping, aviation, and heavy industrial equipment. A battery large enough to power a semi truck across the country would weigh so much it would eat into cargo capacity. Hydrogen can store more energy per kilogram than any battery, and refueling takes minutes rather than hours.
For passenger cars, though, battery EVs have pulled decisively ahead. Charging networks are expanding rapidly, battery costs continue to fall, and ranges above 300 miles are now common. The window for hydrogen to compete in the personal vehicle market has narrowed considerably, and the infrastructure collapse in California, the one place where hydrogen cars were viable, suggests it may be closing further.
