Biogas technology cannot solve every problem of a farm, a village or a big animal production unit. Biogas plants significantly curb the greenhouse effect: the plants lower methane emissions by capturing this harmful gas and using it as fuel. It is the case that direct alcohols cannot be used as aviation fuel because they freeze easily and have low energy densities. A Danish plan to restrict the use of purpose-grown crops for producing biogas has moved a step closer with publication of rules requiring AD plants to report the share of. these factors, speed and operating conditions have been examined and advantages and disadvantages of biogas production have also been demonstrated. The methane portion of the biogas, typically from 50-80% by volume, is very rich in energy and can be used within existing infrastructure. The liquified gas fuel is not as energy rich per volume as diesel or petrol so you would need more storage space for the fuel tank or sacrifice capacity. It can also be directly used for various domestic and industrial purposes. In this work, emphasize on the importance of biogas and the biogas production factors, is intended to contribute public awareness about biogas. Advantages and Disadvantages of Biogas | Worldwide interest in renewable energy sources is gathering momentum.
