Uses of Biogas

Biogas is also called as gobar gas. This gas primarily consists of carbon dioxide and methane. It is a renewable energy source. Biogas is produced due to the decomposition of organic matter. This process occurs through 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. Let’s see some of the uses of biogas

Uses of biogas

Biogas is environment friendly and has various applications. They are cooking, drying, cooling, heating etc. It is used in producing electricity, methanol and production of steam. Below are the some other biogas uses in different fields:

  • Biogas for home
  • Biogas for electricity
  • Advantages of biogas

Biogas for home – cooking:

The biogas is transferred to the cooking place like kitchen from the digester through a tube. Except electricity, biogas when compared to other fuels produces less pollution while cooking. Need not wait for the heat after ignition. It produces instantly. Byproduct of biogas is used as fertilizer. It helps in producing indoor light.

Biogas for electricity:

External combustion engine – When biogas is combusted externally stirling motor is heated. It is heated with the help of heat exchanger. On the expansion of gas in the stirling motor electricity is generated.Since their efficiency is low and are expensive, their use is limited.

Internal combustion engine – Gas motors, gas turbines and diesel engines are some of the examples.

Advantages of biogas:

It helps in agriculture as the byproduct of biogas helps in the production of organic fertilizers. Using of biogas helps in reducing pollution and makes eco friendly environment. It reduces global warming. It is a cheap and affordable technology. Also, it can be used as transportation fuel as well.These were some of theuses.
