How much does it cost to refuel a Toyota Mirai?

Typically about $80 to $110 to refuel in the United States, depending on hydrogen price per kilogram and how full the tank is.

Hydrogen fuel cell vehicles like the Mirai store roughly 5 kilograms of hydrogen in high-pressure tanks. A full refill means topping up the tanks to the standard 70 MPa (about 10,000 psi), delivering the car’s full EPA range. Prices for hydrogen vary widely by station and region, and can change over time. The following explains how the cost is determined and how to estimate it.

What determines the cost to refuel a Mirai

Understanding where the price comes from helps you estimate a fill more accurately. The main factors are the price per kilogram, the number of kilograms needed to top up, and any local taxes or service fees.

• Hydrogen price per kilogram at the fueling station (retail price varies by region and station).


• Tank capacity and fill level used for a full refill (the Mirai typically uses about 5 kilograms per fill).


• Taxes, station fees, or environmental surcharges that can be added at the pump.


• Any incentives or pricing programs that reduce the per-kilogram cost (rare but possible in some programs).

In practice, most fills cost roughly price_per_kg × 5 kg, plus any applicable taxes and fees. This means a typical U.S. fill often falls in the $80–$110 range, with California stations tending to be toward the higher end due to pricing and demand.

Regional price ranges (U.S.)

Hydrogen pricing varies by region. Here is a general snapshot of typical posted ranges you might see at stations across the United States.

• California and some coastal markets: commonly about $18–$26 per kilogram.


• Other metropolitan areas: roughly $15–$22 per kilogram.


• Rural or lower-demand regions: around $14–$20 per kilogram.


• Prices can be higher or lower based on station deals, subsidies, or special programs.

To estimate your cost, multiply the price per kilogram by the Mirai’s approximate fill of 5 kilograms. Always verify the posted price at the station before refueling and account for taxes or fees.

How to estimate your fill cost (quick method)

Use this simple method to estimate refueling costs based on real-time prices at the station.

1. Check the posted price per kilogram at the hydrogen pump or on the station’s app.


2. Assume a fill of about 5 kilograms for the Mirai’s tanks (adjust if your vehicle is not fully depleted).


3. Multiply price per kilogram by 5 kg to get a base cost.


4. Add any local taxes, surcharges, or disposal fees if applicable.

Example: If the price is $18 per kilogram, a full 5-kilogram fill would be about $90 before tax and fees.

Summary

Refueling a Toyota Mirai costs roughly the hydrogen price per kilogram multiplied by about 5 kilograms. In the United States, typical full fills fall roughly in the $80–$110 band, with regional variations and taxes shaping the final price. Always check current station prices and consider any fees or incentives that may apply.

Is hydrogen fuel cheaper than gas?

No, hydrogen fuel is currently not cheaper than gasoline, and the cost per mile for hydrogen fuel cell vehicles is significantly higher than for gasoline vehicles. While hydrogen fuel cell vehicles can be more fuel-efficient, the high cost of the fuel itself makes the cost-per-mile higher. 
Current cost comparison

• Hydrogen is more expensive: Current prices for hydrogen fuel are significantly higher than gasoline on a cost-per-mile basis, sometimes three to four and a half times higher. 
• Reasons for higher cost: The higher cost is due to several factors, including the energy-intensive process of producing hydrogen, and the complex and expensive infrastructure needed for storage and distribution. 
• Potential for future changes: Some projections anticipate future cost reductions for hydrogen, particularly green hydrogen, if production and distribution costs fall and infrastructure improves. 

Factors influencing cost

• Fuel efficiency: Hydrogen fuel cell vehicles are more efficient than gasoline engines, meaning a smaller amount of fuel is needed for the same distance. 
• Production method: The method used to produce hydrogen impacts its cost. 
  • Green hydrogen: (produced from renewable energy) is currently expensive but is expected to become cheaper. 
  • Gray hydrogen: (produced from natural gas) is cheaper to produce but relies on fossil fuels. 
• Incentives: Some areas, like California, offer subsidies that can lower the retail price of hydrogen fuel. 

What this means for drivers

• Higher per-mile costs: For a consumer in 2025, the cost of fueling a hydrogen vehicle is higher than a gasoline vehicle. 
• Potential long-term savings: If the cost of hydrogen fuel decreases significantly in the future, the cost per mile could become more competitive, especially when combined with the higher efficiency of the vehicles. 

Why is Mirai so cheap?

The Toyota Mirai is cheap because its low resale value is driven by a severely limited hydrogen refueling infrastructure, making it impractical for most people, and high hydrogen fuel costs. Additional factors include faster-than-average depreciation due to rapidly evolving technology and a niche market, along with government incentives that lower the initial price but may affect long-term investment potential. 
Key factors contributing to low prices

• Limited hydrogen infrastructure: The U.S. has very few hydrogen fueling stations, with most located in California, and these stations frequently have operational issues, leading to shortages and an unreliable supply. 
• High fuel costs: Even where stations are available, the cost of hydrogen is high, making the total cost of ownership expensive and offsetting potential savings, notes this YouTube video. 
• Rapid depreciation: As a hydrogen fuel cell vehicle in a niche market, the Mirai has a very high depreciation rate. Early models have lost a significant percentage of their value, often exceeding 80% within five years. 
• Market saturation: Many used Mirais are lease returns, creating an oversupply in the used market that drives prices down further. 
• Government incentives: Incentives, such as free hydrogen fuel for several years, can lower the initial purchase price, but the value of these incentives can decrease over time as fuel prices increase, making the car less appealing for future owners, says Top Speed. 
• Concerns about maintenance and reliability: Potential owners are often deterred by concerns about long-term reliability and high repair costs associated with hydrogen fuel cell technology. 

How many miles can a Toyota Mirai go on a full tank?

A Toyota Mirai can go around 402 miles on a full tank, based on its EPA-estimated range. However, this can vary depending on driving conditions and habits. The Mirai has also set a Guinness World Record for driving 845 miles on a single tank in a controlled test. 
Estimated range

• EPA-estimated range: 402 miles for the 2021/2022/2023 XLE model.
• 2022 Limited model: 357 miles. 

Factors affecting range

• Driving conditions: Highway, city, weather, and road conditions all play a role. 
• Driving behavior: Aggressive driving will significantly reduce the range, while hypermiling techniques can increase it. 
• Vehicle condition: A/C use and other factors can affect fuel economy. 

World record

• In a 2021 test, a Mirai drove 845 miles on a single tank of hydrogen, setting a Guinness World Record.
• This was achieved by professional drivers using hypermiling techniques in Southern California. 

How much does it cost to fill up a Toyota Mirai?

The Toyota Mirai Costs $200 To Refill
True Zero is currently the lead hydrogen supplier in California, and currently charges $36 for a kilogram. The Mirai accommodates 5.6 kg of hydrogen in its 142.2-liter tank, meaning you'll have to spend $201.60 to refuel.
