How much does it cost to fill up the Mirai?
Filling a Mirai is typically around $75 to $150 today in the United States, depending on local hydrogen prices and the car’s roughly 5-kilogram tank. The cost fluctuates with regional pricing and fueling patterns.
What determines the cost to fill a Mirai
Several factors determine the price you pay at the pump. Here’s what matters most:
- Hydrogen price per kilogram at the fueling station, which varies by region and operator (generally in the mid-teens to mid-twenties per kilogram in many U.S. markets).
- Tank capacity and how much hydrogen the tank can hold when filled; the Mirai typically carries about 5.0 kilograms of hydrogen, with some model years offering up to about 5.6 kilograms.
- How much of the tank you fill; most drivers fill to full capacity, but the exact amount delivered can vary by station and protocol.
- Station fees, credit-card surcharges, taxes, or local levies that can add a small extra amount per fill.
- Regional supply conditions and station availability, which can affect price and convenience and thus the final cost you pay.
In practice, the final cost equals price-per-kilogram times the kilograms filled, plus any station fees.
Current hydrogen prices and what it means for a full fill
Hydrogen prices at U.S. fueling stations vary widely by region and station. As of 2024–2025, typical market prices range roughly from $16 to $25 per kilogram, with California stations often toward the higher end. A full fill for a Mirai—holding about 5 kilograms of hydrogen, with some versions carrying around 5.6 kilograms—would therefore cost in the neighborhood of $80 to $125, and potentially more if prices are elevated at a given station.
To illustrate typical costs under current pricing, consider these scenarios:
- Hydrogen price: $16/kg; Tank: 5.0 kg → about $80 before fees.
- Hydrogen price: $20/kg; Tank: 5.0 kg → about $100 before fees.
- Hydrogen price: $25/kg; Tank: 5.0 kg → about $125 before fees.
Note: If the Mirai carries more hydrogen (5.6 kg) or if there are additional station charges, the total will scale accordingly. For example, 5.6 kg at $20/kg is about $112 before any extras.
Hydrogen availability and station network
Fueling infrastructure for hydrogen is growing but still limited compared with gasoline or diesel. Availability varies by region, which can influence both price and convenience. In markets with dense station networks, competition can help push prices down, while in areas with few stations, prices may be higher and travel planning more important.
Summary
The Mirai’s fill cost hinges on two main factors: how much hydrogen the tank can hold (roughly 5 kilograms for most models) and how much hydrogen costs at the station (roughly $16–$25 per kilogram in many U.S. markets as of early 2025). That places a full fill in a typical range of about $80 to $125, with potential variation up or down based on local pricing, tank capacity, and any station fees. As hydrogen infrastructure expands, pricing and availability are likely to change — check your nearest fueling station for the most accurate quote.
