Well-to-wheel efficiency of alternative fuelsRange per year per m² of land

Biofuel: 7km

Hydrogen: 160km

Electric: 380km

A solar panel

delivers 105 kWh/m².

A solar panel

delivers 105 kWh/m².

After distribution, charging and storage

in the battery, 77kWh is available to the motor.

An EV drives 5km/kWh, so

77kWh gives 380km range.

After electrolysis, compression and

distribution 63kWh goes into the tank.

The fuel cell generates 31.5kWh of

electricity. The vehicle drives 5km/kWh,

so 31.5kWh gives 160km range.

Most efficient energy crops (palm oil, sugar cane) deliver 0.5L/m²

including sowing, fertilizing, harvesting, refinement and distribution. A vehicle drives 15km/L, so

0.5L gives 7km range.
