Most modern hydrogen fuel cell vehicles (FCEVs) can travel between 350 to 400 miles on a full tank of hydrogen. This range is competitive with, and often exceeds, that of many battery electric vehicles (BEVs) and is a key advantage of the technology. For instance, the 2024 Toyota Mirai is officially rated by the EPA for a 402-mile driving range, while the Hyundai Nexo achieves 380 miles.
The range is primarily determined by the amount of hydrogen fuel stored on board, measured in kilograms (kg). Current models typically hold 5-6 kg of hydrogen in high-pressure tanks. The efficiency of the fuel cell system, which converts hydrogen into electricity to power the motor, is also critical. This efficiency is measured in miles per kilogram (mi/kg) or miles per gallon equivalent (MPGe).
| Vehicle Model | EPA Estimated Range (miles) | Hydrogen Tank Capacity (kg) | EPA Combined MPGe |
|---|
| Toyota Mirai (2024) | 402 | 5.6 | 76 |
| Hyundai Nexo (2024) | 380 | 6.3 | 65 |
| Honda Clarity Fuel Cell (discontinued) | 360 | 5.0 | 68 |
It's important to note that real-world range can be affected by driving habits, speed, terrain, and use of climate control, similar to a gasoline or electric car. The main challenge isn't the range itself, but the availability of hydrogen refueling stations, which are currently concentrated in specific regions like California.
The refueling process, however, is a significant benefit, taking only about 3-5 minutes to fill the tank—comparable to filling a gasoline car and much faster than charging a BEV. For drivers with access to infrastructure, hydrogen cars offer a compelling combination of long range and quick refueling.
