Electricity Generation from Biogas - energypedia.info

The average calorific value of biogas is about 21-23.5 MJ/m³ meaning that 1 m³ of biogas corresponds to 0.5-0.6 l diesel fuel or an energy content of about 6 kWh. However due to conversion losses 1m³ of biogas can be converted only to around 1.7 kWhel. Bigger biogas plants are generally more cost-efficient than smaller ones.
