Compressed Biogas (CBG): The Fuel of the Future

 Compressed Biogas (CBG): The Fuel of the Future

With rising fuel prices, increasing carbon emissions, and growing pressure on natural resources, the global energy sector is rapidly shifting toward sustainable alternatives. One of the most promising solutions in this transition is Compressed Biogas (CBG). Produced from organic waste, CBG is a renewable, eco-friendly fuel that closely resembles CNG in composition and performance. In India, CBG is gaining strong policy support under the SATAT initiative, making it a future-ready fuel for transportation and industry.

Compressed Biogas (CBG

What is Compressed Biogas (CBG)?

Compressed Biogas (CBG) is a purified and compressed form of biogas generated through the anaerobic digestion of organic materials such as crop residue, animal dung, food waste, press mud, and municipal solid waste. After removing impurities like carbon dioxide, hydrogen sulfide, and moisture, the gas contains over 90% methane, making it comparable to conventional CNG.

CBG can be used as a clean fuel for vehicles, industrial heating, and power generation while also supporting waste management and circular economy goals.

How is CBG produced?

The production of compressed biogas involves a structured and scientific process:

  1. Collection of Organic Waste—Agricultural waste, animal waste, food waste, and organic municipal waste are gathered.

  2. Anaerobic Digestion—Microorganisms break down organic matter in oxygen-free digesters to produce raw biogas.

  3. Biogas Upgradation – Impurities are removed to enhance methane concentration.

  4. Compression & Storage – Purified biogas is compressed into cylinders or cascades for storage and transportation.

  5. By-product Utilization – The leftover digestate is used as organic manure, improving soil fertility.

Why is CBG Called the Fuel of the Future?

Compressed biogas stands out as a future fuel due to its sustainability, economic viability, and environmental benefits.

1. Environment-Friendly Energy

CBG significantly reduces greenhouse gas emissions and prevents methane release into the atmosphere from decomposing organic waste.

2. Reduces Fossil Fuel Dependency

By replacing petrol, diesel, and natural gas, CBG lowers India’s reliance on fuel imports.

3. Boosts Rural Economy

CBG plants create local employment opportunities and provide additional income for farmers through waste supply and organic fertilizer sales.

4. Cost-Effective Fuel

CBG is cheaper than conventional fuels and offers long-term price stability.

5. Strong Government Support

Schemes like SATAT (Sustainable Alternative Towards Affordable Transportation) promote CBG production and ensure offtake by oil marketing companies.

Uses of Compressed Biogas

CBG has multiple commercial and industrial applications:

  • Fuel for automobiles (buses, cars, tractors)

  • Industrial heating and boilers

  • Power generation

  • Replacement for CNG and LPG

  • Cooking fuel in commercial kitchens

CBG Business Opportunities in India

Setting up a CBG plant is a high-potential business opportunity due to rising demand and government backing. Entrepreneurs can benefit from:

  • Long-term purchase agreements with OMCs

  • Carbon credit opportunities

  • Sale of organic manure

  • Subsidies and priority lending options

To establish a bankable CBG project, a Detailed Project Report (DPR) is essential. A professionally prepared project report improves loan approval chances and subsidy eligibility.

Role of Project Reports in CBG Plant Financing

Banks and financial institutions require a detailed project report covering technical feasibility, raw material availability, financial projections, and risk analysis. A strong DPR ensures:

  • Faster bank loan approval

  • Eligibility for government subsidies

  • Investor confidence

  • Long-term financial sustainability

Future Scope of CBG in India

India has the potential to produce over 60 million metric tons of CBG annually, making it a key contributor to energy security. With increasing adoption of green fuels, stricter emission norms, and rising waste generation, CBG will play a critical role in India’s clean energy ecosystem.

Conclusion

Compressed Biogas (CBG) is not just an alternative fuel—it is a sustainable energy revolution. By converting waste into wealth, reducing carbon emissions, and supporting economic growth, CBG perfectly aligns with India’s renewable energy goals. With the right planning, policy support, and financial structuring, CBG is truly the fuel of the future.
