2$ per Kg of Green Hydrogen

[Sparty]

Some Hydrogen powered cars can go up to 100 miles or more on a single kilogram.

The Toyota Mirai, for example, has a range of 650 kilometers (404 miles) on a full tank of hydrogen, which is about 5.6 kilograms. This means that the Mirai can go about 115 miles per kilogram of hydrogen.

The Hyundai Nexo has a similar range, at 609 kilometers (378 miles) on a full tank of hydrogen. This is about 109 miles per kilogram of hydrogen.

The actual range of a hydrogen-powered car will also depend on the driving conditions. For example, driving at high speeds or in cold weather will reduce the range.

Overall, hydrogen-powered cars have a range that is comparable to gasoline-powered cars. However, the infrastructure for hydrogen refueling is not as widespread as gasoline refueling, so hydrogen-powered cars are not yet as widely available.

Here are some additional factors that can affect the range of a hydrogen-powered car:

The weight of the car
The aerodynamics of the car
The efficiency of the fuel cell
The temperature of the fuel cell
The pressure of the hydrogen gas

As the technology continues to develop, the range of hydrogen-powered cars is expected to improve.
