mention the disadvantages of biogas
Answers
1. Little Technology Advancements: First of all, the current systems in place used to create biogas are not as efficient as they get. Little new technology has been introduced for streamlining the process and making it more cost effective. As a result, large scale industrial production of biogas is still not on the energy map. Although it could solve the energy issues being faced by countries all over the world, very few investors are willing to put in the startup capital. It is also not the best idea to construct one biogas plant per house, which means that a central system will have to be put into place.
2. Contain Impurities: Biogas contains a number of impurities even after refining processes have been put into place. When compressed for use as fuel, these can become corrosive to the metal parts of engines.
3. Not Attractive on Large Scale: The process of using biogas on a large scale is not economically viable and it is very difficult to enhance the efficiency of biogas systems.
4. Unstable: It is also somewhat unstable, making it prone to explosions if the methane comes in contact with oxygen and become flammable in nature.
