Biogas from Clover-Grass: Sustainability for Environment and Economy

W. Schöberl & P. Zerle
This study assesses the environmental and economical sustainability of biogas production from clover­grass and examines the uncertainty of the results mathematically. Based on real data of a biogas plant in Germany costs and greenhouse gases are calculated and compared to a plant using maize. Then the CO2-abatement costs of changing the biogas substrate from maize to clover-grass are derived. Since most input parameters vary geographically and annually or can only be estimated the outcome can...
