Uses of Biogas

Biogas primarily consists of carbon dioxide and methane. It is a renewable energy source. Biogas is produced due to the decomposition of organic matter through a process known as anaerobic digestion. When plant or animal waste is broken down by bacteria in the absence of oxygen they release gases such as carbon dioxide and methane. Some uses of biogas are detailed in this article.

Uses of biogas

Biogas is environment friendly and has various applications in cooking, drying, cooling, heating, etc. It is used in the production of electricity, methanol, and steam.

Applications of Biogas in Homes

Biogas can be transferred to the kitchen with the help of a digester through a tube. Biogas, when compared to other fuels, produces less pollution while cooking (with an exception of electric current). Furthermore, the byproducts of biogas can be used as fertilizer. Biogas also helps in producing indoor light.

Biogas for Electricity

External combustion engine – When biogas is combusted externally, Stirling motors can be heated with the help of heat exchanger. On the expansion of the gas in the Stirling motor, electricity is generated. Since its efficiency is low and it is relatively expensive, the use of biogas for this purpose is limited.

Advantages of Biogas

It helps in agriculture as the by-product of biogas helps in the production of organic fertilizers. Using biogas helps in pollution control and contributes to an eco-friendly household. It can be used as an alternate fuel to control global warming. It is a cheap and affordable technology. Also, it can be used as a transportation fuel.
