West Asia Tensions Renew Strategic Focus on Compressed Biogas for India's Long-Term Energy Security Transition

Recent Developments:

• Continued geopolitical tensions in West Asia have highlighted India's energy vulnerability due to its heavy dependence on imported hydrocarbons.
• Renewed concerns over disruptions in the Strait of Hormuz, through which nearly 90% of India's LPG imports transit, have strengthened policy focus on Compressed Biogas (CBG) as a domestic, renewable alternative fuel.
• Despite sustained policy support through initiatives such as SATAT, GOBARdhan, and the CBG Blending Obligation, the pace of implementation remains considerably below targets, prompting calls for stronger financial incentives, infrastructure expansion, and waste-based feedstock utilisation.

India's Energy Vulnerability:

Dependence on Imported Hydrocarbons:

• India imports nearly 85% of its crude oil requirement, making the economy highly vulnerable to global supply disruptions and price volatility.
• A substantial share of India's hydrocarbon imports originates from West Asia, exposing the country to geopolitical conflicts in the region.
• Although India has diversified crude oil suppliers over the years, around 90% of LPG imports continue to pass through the Strait of Hormuz, making uninterrupted maritime trade essential for national energy security.

Implications for Energy Security:

• Disruptions in international supply chains can adversely affect fuel availability, inflation, fiscal stability, transportation, industrial production, and household energy consumption.
• Strengthening domestic renewable fuels has therefore become an important component of India's long-term Energy Security Strategy.

Biogas and Compressed Biogas (CBG):

What is Biogas?

• Biogas is a renewable gaseous fuel produced through the Anaerobic Digestion of organic materials such as cattle dung, agricultural residues, municipal organic waste, food waste, and sewage.
• It primarily consists of Methane (CH₄), Carbon Dioxide (CO₂), and trace gases.

What is Compressed Biogas (CBG)?

• After purification and compression, biogas is converted into Compressed Biogas (CBG).
• CBG is chemically equivalent to Compressed Natural Gas (CNG) and can directly replace fossil-based natural gas in transport, industries, and domestic applications.
• Since it is produced from renewable biomass, CBG is considered a Carbon-Neutral Fuel.

Advantages of Biogas:

Energy Security:

• Domestic production of CBG reduces dependence on imported crude oil and natural gas.
• It diversifies India's energy basket and improves resilience against international supply disruptions.

Environmental Benefits:

• Biogas converts agricultural residues and organic waste into clean energy, reducing methane emissions from uncontrolled decomposition.
• It supports India's commitments under the Paris Agreement and contributes towards achieving Net Zero emission goals.

Waste Management:

• Biogas promotes scientific utilisation of cattle dung, crop residues, municipal organic waste, food waste, and sewage.
• It reduces open dumping, stubble burning, and associated environmental pollution.

Rural Economy:

• Biogas plants generate additional income for farmers through biomass supply.
• Production of Bio-slurry provides nutrient-rich organic manure that improves soil health while reducing dependence on chemical fertilisers.

Multiple End Uses:

• CBG can be utilised for:
• Electricity generation.
• Industrial heating.
• Household cooking.
• Transportation fuel.
• Injection into the City Gas Distribution (CGD) network.

Government Initiatives:

SATAT Initiative:

• The Sustainable Alternative Towards Affordable Transportation (SATAT) initiative was launched in 2018 to establish 5,000 commercial CBG plants across the country.
• As of 3 June 2026, only 132 plants had become operational, highlighting a significant implementation gap.

GOBARdhan Scheme:

• The Galvanising Organic Bio-Agro Resources Dhan (GOBARdhan) Scheme promotes conversion of organic waste into wealth through biogas and bio-fertiliser production.
• Financial support includes:
• Grants up to ₹50 lakh per district for community biogas plants.
• ₹564 crore for biomass collection machinery.
• ₹994 crore for pipeline infrastructure connecting CBG plants with the gas grid.

Mandatory CBG Blending:

• In 2023, the National Biofuels Coordination Committee (NBCC) approved mandatory blending of CBG in the CGD sector.
• The blending obligation begins at 1% during FY26 and will gradually increase to 5% by FY29.

Budget Announcement:

• The Union Budget 2024-25 announced phased mandatory blending of CBG in CNG used for transportation and Piped Natural Gas (PNG) supplied for domestic cooking.

Ground Reality and Implementation Status:

Slow Progress:

• Despite ambitious policy targets, actual commissioning of commercial CBG plants remains limited.
• According to Government data released during August 2025, only 36 medium-sized biogas plants had been established under the MNRE Biogas Programme during the preceding three years.

Implementation Gap:

• The gap between policy announcements and project execution indicates persistent structural constraints requiring targeted policy intervention.

Major Challenges:

Infrastructure Deficit:

• Inadequate biomass collection systems, transportation facilities, pipeline connectivity, and storage infrastructure increase project costs.

Financial Constraints:

• High initial capital requirements discourage private investment.
• Small developers face difficulties in accessing institutional finance and affordable credit.

Technology Costs:

• Advanced purification, compression, and quality control technologies require substantial investment and specialised technical expertise.

Limited Private Sector Participation:

• Uncertain commercial returns and regulatory delays reduce investor confidence in the sector.

Lessons from International Experience:

Germany's Experience:

• Germany significantly expanded biogas production through the Renewable Energy Sources Act, 2000, which guaranteed long-term producer income.
• However, generous incentives encouraged extensive cultivation of maize exclusively for biogas production.
• Excessive dependence on maize reduced crop diversity and created concerns regarding food security.
• The Government subsequently imposed limits on maize utilisation as feedstock for biogas plants.

Denmark's Model:

• Denmark aims to replace conventional natural gas with biomethane by 2030.
• The country discourages cultivation of dedicated energy crops for biogas production.
• Livestock manure, agricultural residues, and organic waste constitute the principal feedstock, thereby avoiding competition with food production.

Emerging Challenges for India:

Changing Cropping Pattern:

• The Economic Survey 2025-26 observed rapid expansion in maize cultivation.
• Maize productivity increased from approximately 2.56 tonnes/hectare in FY16 to 3.78 tonnes/hectare in FY25.

Food Security Concerns:

• Attractive administered pricing for maize-based ethanol has encouraged farmers to shift away from pulses, oilseeds, millets, soybean, and cotton.
• Such crop substitution could increase India's dependence on imports of edible oils and pulses while reducing agricultural diversification.

Feedstock Competition:

• Excessive dependence on food crops for biofuel production may create long-term conflicts between Energy Security and Food Security.

Way Forward:

Prioritise Waste-Based Feedstock:

• Agricultural residues, cattle dung, municipal organic waste, and sewage should remain the primary feedstock for biogas production.
• Food crops should be avoided wherever possible to safeguard national food security.

Strengthen Financial Incentives:

• Government support may include:
• Accelerated depreciation.
• Tax holidays.
• Interest subvention.
• Viability Gap Funding.
• Long-term purchase guarantees.

Expand Infrastructure:

• Accelerate development of biomass aggregation systems, storage facilities, pipeline connectivity, and City Gas Distribution infrastructure.

Improve Access to Finance:

• Simplify institutional lending procedures for small developers and provide dedicated financing mechanisms for renewable gas projects.

Replicate Ethanol Blending Success:

• India increased ethanol blending in petrol from 1.5% in 2014 to 20% by December 2025, achieving the target five years ahead of schedule.
• Similar policy consistency, assured procurement, and infrastructure support could accelerate CBG adoption.

Strengthen Circular Economy:

• Promote integrated waste management systems combining renewable energy production, organic fertiliser generation, methane mitigation, and sustainable agriculture.

Conclusion:

• Compressed Biogas offers India a strategic opportunity to simultaneously strengthen Energy Security, reduce fossil fuel imports, improve waste management, enhance rural incomes, and support climate commitments.
• Achieving these objectives will require sustained policy support, faster infrastructure development, stronger private investment, and prioritisation of waste-based feedstock over food crops to balance both Energy Security and Food Security.
