In the United States, the Hyundai Nexo is currently the only hydrogen car available for purchase. The Nexo has a starting price of $58,300, and it is eligible for a federal tax credit of $7,500. Other hydrogen cars that are available in other countries include the Toyota Mirai, the Honda Clarity Fuel Cell, and the Mercedes-Benz GLC F-Cell.
The cost of hydrogen fuel itself can also vary significantly depending on the location. In California, where there is a relatively well-developed hydrogen infrastructure, hydrogen fuel can cost as little as $3 per kilogram. In other parts of the country, hydrogen fuel can cost as much as $10 per kilogram.
Overall, the cost of owning and operating a hydrogen car can be higher than the cost of owning and operating a gasoline-powered vehicle. However, as the technology continues to develop and the hydrogen infrastructure improves, the cost of hydrogen cars is expected to come down in the future.
