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.
