Introduction

India imports nearly 85% of its crude oil, making its energy security vulnerable to geopolitical disruptions, particularly in West Asia. In this context, Compressed Biogas (CBG) offers a renewable, indigenous and cleaner alternative to reduce import dependence while promoting rural development and climate sustainability.

What is Biogas?

1. Renewable Fuel from Organic Waste

Biogas is produced through the anaerobic decomposition of organic waste such as crop residue, animal dung and food waste. It primarily consists of methane (CH₄), carbon dioxide (CO₂) and traces of other gases.

2. Purified as Compressed Biogas (CBG)

After purification, biogas is converted into Compressed Biogas (CBG), which is chemically identical to CNG. It is a renewable, carbon-neutral fuel that can replace fossil fuels in multiple sectors.

3. Wide Range of Applications

CBG is used as a transport fuel, cooking fuel, and for electricity generation and industrial heating. It can also be supplied through Piped Natural Gas (PNG) networks, reducing dependence on imported fuels.

Why is Biogas Important for India?

1. Strengthening Energy Security

• Reduces import dependence: Biogas substitutes imported crude oil and LNG with a domestically produced renewable fuel, improving India’s energy self-reliance.
• Enhances energy resilience: It diversifies the energy mix and reduces vulnerability to geopolitical disruptions, such as tensions in West Asia affecting fuel supplies.

2. Promotes a Circular Economy

• Converts waste into wealth: Agricultural residue, animal dung, food waste and municipal waste are transformed into clean energy instead of becoming pollutants.
• Generates valuable by-products: The slurry left after biogas production serves as nutrient-rich organic manure, reducing dependence on chemical fertilizers.

3. Supports Climate Change Mitigation

• Low-carbon energy source: Biogas is a carbon-neutral fuel that lowers greenhouse gas emissions by replacing fossil fuels.
• Helps achieve climate commitments: It contributes to India’s Paris Agreement targets, Panchamrit goals and Net Zero emissions target by 2070.

4. Tackles Stubble Burning

• Provides economic value to crop residue: Farmers can supply agricultural waste to biogas plants instead of burning it, creating an additional source of income.
• Improves environmental quality: Reduced stubble burning lowers air pollution, improves soil health and protects public health.

5. Promotes Rural Development

• Creates rural livelihood opportunities: Biogas plants generate employment in biomass collection, transportation, plant operation and maintenance.
• Strengthens the rural economy: They encourage local entrepreneurship, improve waste management and provide farmers with an additional and sustainable income source.

Government Initiatives to Promote Biogas

1. SATAT Scheme (2018) (Sustainable Alternative Towards Affordable Transportation)

• Promotes CBG production: The scheme aims to establish 5,000 Compressed Biogas (CBG) plants to reduce dependence on imported fossil fuels and promote clean transportation.
• Limited progress: Against the target of 5,000 plants by 2023, only 132 plants were operational by June 2026, highlighting a significant implementation gap.

2. GOBARdhan Scheme (Galvanising Organic Bio-Agro Resources Dhan)

• Converts waste into wealth: The scheme encourages the scientific management of organic waste by converting agricultural residue, cattle dung and municipal waste into biogas and organic manure.
• Financial and infrastructure support: The government provides up to ₹50 lakh per district for community biogas plants, ₹564 crore for biomass collection machinery and ₹994 crore for pipeline connectivity.

3. Mandatory CBG Blending Obligation

• Promotes market demand: The National Biofuels Coordination Committee has mandated the blending of CBG with natural gas to ensure a stable market for producers.
• Phased implementation: The blending target starts at 1% in FY26 and gradually increases to 5% by FY29 for both Compressed Natural Gas (CNG) and Piped Natural Gas (PNG), supporting India’s clean energy transition.

Challenges in Biogas Development

1. Slow Implementation

Despite ambitious targets under the SATAT scheme, only 132 CBG plants have become operational against the target of 5,000 plants, reflecting significant implementation and execution bottlenecks.

2. High Capital Cost

The establishment of biogas plants requires substantial upfront investment in technology and infrastructure, while long gestation periods reduce their commercial attractiveness.

3. Limited Access to Finance

Biogas projects often face difficulties in obtaining institutional credit due to perceived risks, lack of collateral and uncertain returns on investment.

4. Inadequate Infrastructure

Weak biomass collection networks, transportation facilities, storage systems and gas pipeline connectivity hinder the efficient functioning and scaling up of CBG plants.

5. Low Private Sector Participation

Low profitability, policy uncertainties and high operational costs discourage private investors from entering the biogas sector at scale.

6. Adverse Impact on Agriculture and Food Security

Rising incentives for maize-based biofuels have encouraged farmers to shift from pulses, oilseeds and millets towards maize cultivation, potentially threatening crop diversity, food security and increasing dependence on imports of edible oils and pulses

SDGs Covered

• SDG 7 – Affordable and Clean Energy
• SDG 11 – Sustainable Cities
• SDG 12 – Responsible Consumption
• SDG 13 – Climate Action
• SDG 15 – Life on Land

Way Forward

1. Strengthen financial support: Provide capital subsidies, Viability Gap Funding (VGF), soft loans and interest subvention to improve the financial viability of CBG projects and attract investment.
2. Offer tax incentives: Introduce accelerated depreciation, tax holidays and GST rationalisation to reduce project costs and encourage greater private sector participation.
3. Develop robust infrastructure: Strengthen biomass aggregation, storage facilities, transportation networks and gas pipeline connectivity to ensure an efficient and reliable CBG supply chain.
4. Promote waste-based feedstock: Prioritise crop residue, animal dung and municipal organic waste as feedstock while discouraging excessive dependence on food crops like maize to safeguard food security.
5. Ensure a stable pricing mechanism: Provide assured offtake and remunerative prices for CBG producers to create market certainty and improve investor confidence.
6. Promote Public-Private Partnerships (PPPs): Encourage collaboration between the government and private sector to improve technology adoption, operational efficiency and large-scale deployment of biogas plants.
7. Integrate biogas with the rural economy: Involve Farmer Producer Organisations (FPOs), cooperatives and Panchayats in biomass collection and supply chains to generate rural employment and ensure a sustainable feedstock ecosystem.

Conclusion

Compressed Biogas (CBG) can strengthen India’s energy security while promoting sustainable agriculture, waste management and rural development. With effective implementation, adequate incentives and a focus on waste-based feedstock, CBG can become a key pillar of India’s clean energy goal (2030) and Atmanirbhar Bharat.
