Advantages and Disadvantages of Biogas

Last Updated on: 22nd November 2023, 02:50 pm

What exactly is biogas?

The decomposition of organic material, such as leftover food and animal waste, produces the renewable fuel known as biogas. Investigate the production of biogas and how it can be used to power our vehicles, warm our houses, and provide us with electricity.

Methane and carbon dioxide are the two most common components of biogas. Small amounts of siloxanes, hydrogen sulfide, and water might be present, too. Biogas produced from anaerobic digestion can be burned alongside oxygen to provide direct heat for cooking. It can also generate power by boiling water to create steam and driving a turbine attached to an electric generator.

Compressing biogas is just as simple as natural gas, so it may be used to fuel vehicles. Even better, biogas can be refined into biomethane, a biofuel that meets or exceeds the quality standards for natural gas. A by-product of anaerobic digestion is digested, a nutrient-rich substance often used as fertilizer.

Biogas has many benefits

It’s a sustainable power supply

Biogas is made from renewable resources. Manure, food remains, and crop residue will always be available because of the perennial nature of trees and crops.


Technically, no combustion occurs during biogas production because oxygen is not required. In the absence of burning, no greenhouse gases are released into the air.

However, both the biological decomposition process and the use of biogas result in the release of carbon dioxide. The main distinction is that renewable energy sources release much less carbon dioxide than fossil fuels.

Utilizing biogas results in an equivalent volume of carbon dioxide to what is required for plant growth. This helps maintain a reasonable level of atmospheric carbon dioxide.


Its dependability stems from the fact it is generated through eco-friendly means. Solar and wind power, for example, can only generate electricity during specific times of day and meteorological conditions. The manufacturing of biogas proceeds rain or shine. Continuous (round-the-clock) biogas production is maintained.

Problems with Biogas

  • Low Rates of Technological Progress
  • Current biogas-producing technologies are inefficient

New technologies have not been developed to streamline the procedure while increasing output and decreasing costs.

Thus, mass production to meet the needs of a vast population remains impossible. Although existing biogas plants do have the potential to address some of the world’s energy demands, few private investors or governmental entities are eager to back the industry—consequently, many people with little energy need installed biomass systems in their houses.

  • The production of biogas is a process that is sensitive to temperature

The generation of biogas, much like the production of energy from other forms of renewable and sustainable resources, is temperature-sensitive and is affected by the elements of the environment.

The bacteria responsible for creating biogas from the decomposition of organic materials require a particular temperature to function at their most efficient level. The helpful bacteria require a temperature of 37 degrees Celsius to work properly. If temperatures fall below that threshold, the digesters require heat from an external source.

  • It wouldn’t be profitable enough

The economics of biogas are less favourable than those of other biofuels, especially on an industrial scale. Biogas plants are notoriously difficult to improve, which is why few private investors and governments have put money into the industry.
