- •
Six crops have been compared for production of biogas.
- •
Crop cultivation related costs, energy inputs and yields are presented.
- •
Methane yield per ha twice as high for sugar beet as for ley and hemp.
- •
Energy input 1/3 lower when digestate replaces mineral fertilizer in cultivation.
- •
Crop production costs range from 9 (fresh triticale) to 22 (hemp silage) €/GJ CH4.
