Green Gold: Compressed Biogas 

Beyond Waste: Harnessing Compressed Biogas for a Sustainable Tomorrow 


Compressed biogas is environmentally friendly, reduces greenhouse gas emissions, and generates revenue from waste materials. It is cheaper than traditional fossil fuels and is an attractive option for commercial and industrial use. Let’s dive deep into the biogas industry to know more. 

Have you heard about the most recent innovation in renewable energy? Biogas compression is a technique that has the potential to revolutionize the way we create energy from biological waste. Biogas is a mixture of methane and carbon dioxide created through anaerobic digestion, and it has enormous promise as a renewable resource. However, in order to make data more accessible, we need effective compression techniques that are simple to store, carry, and use.

In this blog post, we’ll take a closer look at biogas compression, including its concepts, applications, and critical role in creating a more sustainable future. 

The breakdown of organic waste products, including food scraps, sewage, and agricultural waste, produces biogas, a renewable energy source. Biogas is a flexible and sustainable energy source since it may be utilized to produce fuel, heat, and power. However, biogas needs to be compressed in order to be fully utilized as an energy source. Compression raises the energy density of biogas, which facilitates and lowers the cost of storage and transportation.

After that, the compressed biogas can be used to a variety of uses, such as power generation and automobile fuel. In the field of renewable energy, biogas compression is essential because it allows us to use this precious resource effectively and efficiently, which lessens our dependency on fossil fuels.

Is Compressed Biogas the Ultimate Sustainable Solution?

Biogas compression has various advantages for the environment. By stopping the atmospheric release of methane, a powerful greenhouse gas, it first lowers greenhouse gas emissions. When compared to petroleum fuel, compressed natural gas derived from biogas can cut greenhouse gas emissions by up to 91%.

We can stop the release of biogas into the atmosphere, which would exacerbate global warming, by trapping and compressing it. Furthermore, compared to conventional fossil fuels, compressed biogas burns cleanly and creates fewer pollutants, improving air quality and lowering respiratory ailments. 

Furthermore, compressed biogas can be used to transport passengers instead of fossil fuels. This is especially crucial for the transportation industry, which contributes significantly to the world’s greenhouse gas emissions. For transportation by land, air, and sea, internal combustion engines (ICEs) remain a significant source of pollution; in 2022, ICEs produced around eight billion metric tons of carbon dioxide equivalent (GtCO2e).

Transportation was the second-largest emitter of greenhouse gases (GHGs) in the world in 2022, accounting for almost 14% of total emissions. Compressed biogas can greatly lower carbon dioxide emissions and enhance air quality when used as a fuel for vehicles. 

Unleashing the Compressed Biogas Industry Landscape 

The biogas compression industry is predicted to value USD 156.5 billion with a compound annual growth rate of 15.21% during the forecast timeframe i.e., 2024-2036. The growing production of biogas for various applications such as heating, cooking, and electricity production is one of the major factors propelling the growth of the biogas compression industry.

Furthermore, a surge in demand for advanced biogas systems will increase as more and more investments are made in reliable, high-quality technology for biogas plants. Moreover, biogas as a fuel for transport applications is becoming more and more popular. Biogas-powered vehicles can lower CO2 emissions by 75% to 200% compared to fossil fuels. 

Power generation segment dominated with the largest revenue of 56.18 billion through 2036. Biogas compressors used in power generation play an important role. Ensure the appropriate use of biogas as a sustainable energy source. Biogas compressors are designed to optimize combustion in gas engines and turbines by pressurizing them to the necessary levels. Biogas CHP systems often use positive displacement or centrifugal compressors based on flow rate and pressure requirements.

On the basis of region, Europe is anticipated to grow majorly with an industry size of 85.54 billion during the projected period. The industry expansion can be attributed to the growing production of biogas in the region. Europe produced approximately 20 billion cubic meters of biogas in 2020. Germany, France, Italy, and other countries in the region have played a leading role. Germany is Europe’s largest market, accounting for two-thirds of installed biogas facilities.

In Europe, energy crops are the dominant feedstock for the biogas business. However, policies have lately evolved to employ crop leftovers, sequential crops, animal waste, and methane captured from landfills.

Is Compressed Biogas the Lucrative Renewable Energy Solution We Need? 

What if it is possible to make a tidy profit by turning organic waste into valuable energy? Biogas projects are not only environmentally friendly but also wallet-friendly. So, let’s take a dive and explore how these projects are economically viable. 

Biogas projects make money with the help of multiple streams. Foremost, the sale for compressed biogas has increased due to its popularity in various fields such as electricity generation, heating, or even as a fuel. Additionally, certain projects may qualify for renewable energy incentives, grants, or carbon credits, further improving the potential financial value.

Projects that compress biogas hold promise for becoming energy independent, particularly for small towns and farming enterprises. One powerful greenhouse gas that can be used as a renewable energy source is methane, which is found in biogas, which is created when organic waste is digested anaerobically. These initiatives, which use biogas as a fuel source, contribute to the reduction of greenhouse gas emissions while providing a sustainable means of supplying farmers and rural communities with energy.

On the farm, the digestate produced by the biogas plant can be further processed and applied as an organic insecticide and fertilizer. The use of organic fertilizer, which enhances fertility and soil health, increases agricultural output, which is the main advantage of erecting a biogas plant. The biogas digestate’s humic acid helps to increase the soil’s quality and conditions it.Both professional and untrained workers could find great career opportunities in the biogas industry. The creation of more jobs can lead to more sustainable means of subsistence and less reliance on agriculture.

Recent Global Biogas Compression Projects 

  • In keeping with its dedication to sustainable energy solutions, BPCL (Bharat Petroleum Corporation Limited) has said that it plans to build two compressed biogas (CBG) plants in Raipur and Bhilai. These plants are expected to have a major impact on lowering carbon emissions and improving the environment. 
  • A mission-driven deep-tech business focused on biogas liquefaction technologies, SUBLIME Energy, has raised €11.5 million in funding to expedite the direct use of its ground-breaking technology on farms.
  • Pig excrement was the main source of manure pollution in China in 2017, accounting for 2 × 1012 kg. The production of crops has a major impact on the production of manure-generated biogas, according to a correlation study between the livestock industry and biogas production.

Government Policies and Regulations Shaping the Compressed Biogas Sector 

  • India is committed to reaching its net zero goal by 2070, and the present administration and leadership have implemented several measures to cut emissions. A significant contributor to the decrease in emissions is compressed biogas (CBG), that is supported under the SATAT Scheme (Sustainable Alternative Towards Affordable Transportation).
