Each cubic meter (m 3) of biogas contains the equivalent of 6 kWh of calorific energy. However, when we convert biogas to electricity, in a biogas powered electric generator, we get about 2 kWh of useable electricity, the rest turns into heat which can also be used for heating applications. 2 kWh is enough energy to power a 100 W light bulb for 20 hours or a 2000W hair dryer for 1 hour.
The biogas produced by the Penn State digester is approximately 60 percent methane and 40 percent carbon dioxide. This means that the gas has 60 percent of the energy in natural gas or about 600 Btu per cubic foot (22 MJ/m 3).iogas. The biogas produced by the Penn State digester is approximately 60 percent methane and 40 percent carbon dioxide. This means that the gas has 60 percent of the energy in natural gas or about 600 Btu per cubic foot (22 MJ/m 3). The methane content of the biogas will fluctuate according to digester conditions.
