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.
Biogas can provide renewable energy in the form of electricity, heat, and transport fuel. The generation of renewable electricity from biogas is well established, but the enhancement of biogas to biomethane for use as a vehicle fuel or for injection into the gas grid is increasingly being promoted.O 2 and H 2 S removal by absorption in water 3.
