There is no universal cost winner between a hydrogen fuel-cell car and a battery-electric vehicle (EV). The result depends on the vehicles and purchase terms you compare, local hydrogen and electricity prices, how you refuel or charge, annual mileage, how long you keep the car, maintenance, and whether fueling or charging is practical where you live.
A useful starting point is energy cost per 100 miles, but that is only one part of ownership cost. California examples put home-charged EV energy at about $7 per 100 miles and hydrogen at about $55 under specific price and efficiency assumptions. Those figures illustrate how far local costs can differ; they are not a nationwide forecast.
What counts as the cost of owning a hydrogen car or EV?
Compare the costs over the same ownership period and mileage, not just the price at the pump or charger. A practical comparison separates the vehicle purchase, energy, maintenance, and access costs, then applies the same assumptions to both vehicles.
- Purchase: Use comparable vehicle classes and model years. State whether you are comparing MSRP or transaction prices, and account for financing and incentives if known.
- Energy: For hydrogen, use the price per kilogram and the vehicle’s miles per kilogram. For an EV, use the electricity price and miles per kilowatt-hour, distinguishing home charging from public Level 2 and DC fast charging.
- Maintenance: Use model-specific estimates if available. A modeled allowance is not the same as an owner’s actual repair bill.
- Access: Include whether you can charge at home or have usable public chargers, and whether a hydrogen station is convenient and operating reliably near your routes.
- Ownership horizon: Set annual mileage and years held consistently. A lower cost per mile does not automatically mean a lower total outlay if the purchase costs differ.
The National Renewable Energy Laboratory’s 2024 levelized cost of driving (LCOD) methodology combines vehicle and charger capital costs, fuel, and maintenance. It assumes $0.06 per mile for light-duty BEV and FCEV maintenance and repair, escalating that amount over time. NREL describes LCOD as a simplified per-mile estimate rather than a comprehensive real-world total-cost-of-ownership calculation. Its model also assumes a 7% discount rate and vehicle lives of 17 years for compact and midsize cars, 20 years for SUVs, and 25 years for pickups; these are modeling inputs, not a prediction of how long an individual will own a car.

- The Hydrogen fuel trolley uses zinc particles and food grade citric acid to synthesize hydrogen, and then uses the produced hydrogen and air to generate electricity to drive the trolley.
- During the experiment, please use 80℃ hot water for Combination reaction (if the water temperature is low, the amount of hydrogen and air pressure from the Combination reaction are insufficient, the fuel cell cannot be used for power generation), and then take off the plug of the vent pipe at the lower part of the fuel cell, release the gas in the rubber hose immediately, and then plug it back immediately, so that only pure hydrogen and air are in the fuel cell, so that the fuel cell can generate hydrogen air power.
The U.S. Department of Energy’s January 2025 comparison likewise has a defined scope: it models powertrain-related purchase costs for representative vehicle classes, excluding incentives, discounts, tax credits, and non-powertrain product differences. The modeled costs are not a buyer’s transaction price. DOE’s analyzed light-duty battery-cost assumptions were $128–133 per kilowatt-hour; modeled BEV high-voltage battery costs in 2024 dollars were $9,185 for a compact car, $9,929 for a midsize car, $11,032 for a midsize SUV, and $15,368 for a pickup. These component figures help explain the model, but they do not establish a full sticker-price comparison between a hydrogen car and a comparable EV. DOE’s 2025 clean-vehicle purchase-cost report
How much does it cost to fuel a hydrogen car per mile?
Calculate hydrogen energy cost as the pump price per kilogram divided by the car’s miles per kilogram. California Drive Clean’s illustrative comparison uses $36 per kilogram and 65 miles per kilogram, which works out to about $0.55 per mile, or about $55 per 100 miles. These are California scenario assumptions, not a universal hydrogen price or efficiency figure. California Drive Clean’s vehicle comparison and assumptions
For your own estimate, replace both inputs with the price at a station you can use and the efficiency of the specific vehicle. If either differs, the cost per mile changes. A published efficiency rating can help compare vehicles, but it does not tell you what hydrogen costs at your local station.

What does it cost to charge an EV for 100 miles?
California Drive Clean gives approximate EV energy costs under the rates and charging scenarios shown below. They are estimates, not guaranteed bills; actual cost depends on local electricity prices, vehicle efficiency, fees, and charging mix.
| Charging method | Assumed electricity rate | Illustrative cost per 100 miles |
|---|---|---|
| Home charging | $0.26/kWh, time-of-use rate | About $7 |
| Public Level 2 | $0.30/kWh | About $8 |
| DC fast charging | $0.40–$0.50/kWh | About $11 |
Under the same page’s hydrogen assumptions—$36/kg and 65 miles/kg—the hydrogen estimate is about $55 per 100 miles. This illustrates a large energy-cost gap in that California scenario, but it is not a controlled comparison of every EV and hydrogen model, nor does it include purchase, maintenance, or infrastructure access. California Drive Clean’s vehicle comparison and assumptions
To estimate your own EV cost, divide your electricity rate per kilowatt-hour by the car’s miles per kilowatt-hour, then multiply by 100. Use a rate that reflects how you actually charge; a home rate is not appropriate if most charging happens at public fast chargers.

Is a hydrogen car cheaper to run than an electric car?
Not necessarily, and the answer cannot be inferred from fuel type alone. In California Drive Clean’s stated scenario, the listed hydrogen cost per 100 miles is substantially higher than its home, Level 2, and fast-charging EV estimates. In another location, the energy prices, vehicle efficiencies, and charging mix may differ. Energy cost is only one part of total ownership cost.
Efficiency ratings also need context. Toyota lists EPA-estimated combined ratings of 74 MPGe for the 2025 Mirai XLE and 57 MPGe for the 2025 Honda CR-V e:FCEV. MPGe is an efficiency measure; it does not state the local price of hydrogen or electricity, and it is not itself a cost-per-mile comparison. Toyota’s Mirai model information

The Department of Energy’s onboard-storage target discussion defines well-to-power-plant efficiency to include hydrogen production, delivery, liquefaction, compression, dispensing, and onboard efficiency. That system-level measure is distinct from an owner’s pump-price calculation: it explains the broader energy pathway but does not replace local cost inputs.

Does the purchase price settle the comparison?
No. A vehicle’s announced MSRP is a useful starting point, but it does not show a matched cost difference against an EV after incentives, discounts, financing, equipment, and regional availability. Toyota announced an expected MSRP of $51,795 for the 2025 Mirai. Toyota also describes an eight-year/100,000-mile warranty on key fuel-cell components; that warranty term is model-specific and does not make the Mirai’s purchase price directly comparable to a similarly equipped BEV.

For a fair purchase comparison, choose the same general vehicle class and include the actual prices and incentives available to you. DOE’s modeled component-cost analysis cannot supply those buyer-specific numbers because it excludes several market and product factors.

Hydrogen access is regional, and statewide capacity does not guarantee a convenient station for a particular driver. A 2025 assessment by the California Energy Commission and California Air Resources Board estimated that California’s network could serve about 36,000 light-duty fuel-cell electric vehicles under then-current conditions. It estimated 14,415 such vehicles were on California roads at the end of the third quarter of 2024. A subsequent 2026 report said statewide capacity exceeded demand while access had declined in some areas with concentrated registrations. CEC and CARB hydrogen refueling station network assessment

Before choosing a hydrogen car, check a current local station map and station status for the places you routinely travel. For an EV, check charger locations and whether home charging is possible. These practical constraints can outweigh a theoretical statewide capacity figure or an energy-cost estimate.
How to compare your own five-year or longer cost
- Choose comparable vehicles. Match vehicle class and use case, then record model year, trim, purchase price, and applicable incentives or discounts.
- Set the same ownership period and mileage. For example, calculate total miles from your expected annual driving and years of ownership. Use the same figures for both vehicles.
- Estimate energy costs using local inputs. For hydrogen, divide the station’s price per kilogram by the car’s miles per kilogram. For an EV, divide the applicable electricity rate by miles per kilowatt-hour. Multiply each result by total miles.
- Reflect your real fueling or charging pattern. Separate home, public Level 2, and DC fast charging if you use more than one. For hydrogen, verify practical station access and status.
- Add purchase, financing, maintenance, and other costs consistently. Use comparable estimates and note what is excluded. Do not treat NREL’s $0.06-per-mile maintenance assumption as a universal observed cost.
- Compare the resulting totals and test alternatives. Recalculate with different electricity rates, hydrogen prices, mileage, or ownership periods to see which assumptions drive the result.
Natural Resources Canada’s Mirai vehicle page describes fuel-cell operation and provides model-year fuel-consumption data, but its comparison table lists annual fuel cost as unavailable. It therefore does not provide a directly comparable annual-cost answer for this decision. Natural Resources Canada’s vehicle and fuel-consumption information
