The Core Argument
India’s energy crisis of 2025-26, triggered by West Asia conflict disruptions and LPG supply shocks, has revealed a structural vulnerability that years of progressive energy policy have not addressed: India imports 88.6% of its crude oil and relies almost entirely on Middle East LPG, with domestic gas production covering barely half its requirements. The editorial argues that Compressed Biogas (CBG) — produced from agricultural waste, urban organic waste, and sewage — offers a viable, scalable domestic alternative that simultaneously addresses energy security, rural employment, environmental sustainability, and import substitution.
India’s Energy Vulnerability — The Numbers
Import Dependence (2025-26)
| Energy Source | Import Dependence | Primary Suppliers |
|---|---|---|
| Crude oil | 88.6% | Saudi Arabia, Iraq, UAE, Russia |
| LPG | ~60% imported | Middle East (Qatar, UAE) |
| Natural gas | Domestic production ~50% of demand | Domestic + LNG imports |
| Coal | ~25% imported (coking coal) | Australia, Indonesia, South Africa |
| Uranium (nuclear) | ~85% imported | Kazakhstan, Canada, Australia |
Hormuz Dependency: ~80-85% of India’s oil imports transit the Strait of Hormuz. Any closure or military escalation in West Asia directly threatens India’s energy supply.
LPG Dependency — The PM-UJJWALA Vulnerability
PM Ujjwala Yojana (PMUY, 2016): 10 crore+ BPL connections given free LPG cylinders. This was a transformational clean cooking fuel initiative — but it created a large urban-rural consumer base dependent on imported LPG.
| PMUY Data | Figure |
|---|---|
| LPG connections distributed | 10+ crore (100 million+) |
| Target beneficiaries | Women below poverty line |
| Launch | May 2016 |
| LPG retail price (subsidised) | ~₹500-800/cylinder |
| Market price | ~₹900-1100/cylinder |
The 2025-26 LPG price spike following West Asia disruptions has hit PMUY beneficiaries hardest — exposing the structural flaw of substituting firewood/biomass with imported fossil fuel.
What Is Compressed Biogas (CBG)?
CBG is biogas (methane + CO₂) produced by anaerobic digestion of organic feedstocks, then compressed and purified to approximately 95% methane purity — comparable to Compressed Natural Gas (CNG).
Feedstocks for CBG Production
| Feedstock | Source | Availability |
|---|---|---|
| Agricultural residue (paddy straw, sugarcane bagasse) | Farms | ~500-600 million tonnes/year |
| Cattle dung | Livestock sector | ~300 million cattle |
| Municipal Solid Waste (organic fraction) | Urban areas | ~100 million tonnes/year |
| Press mud (sugar mills) | Sugar industry | Abundant |
| Sewage sludge | Urban ULBs | Abundant |
India has the world’s largest livestock population and generates enormous agricultural residue — making it uniquely positioned for biogas production.
CBG vs LPG vs CNG
| Parameter | LPG | CNG | CBG |
|---|---|---|---|
| Primary use | Cooking, heating | Vehicle fuel | Both |
| Origin | Refinery/imported | Natural gas | Biomass fermentation |
| Carbon footprint | High | Moderate | Low/Carbon neutral |
| Domestic availability | Low | Moderate (gas fields) | High |
| Rural employment potential | Nil | Nil | High |
Government Policy — SATAT Scheme
SATAT (Sustainable Alternative Towards Affordable Transportation, 2018):
| Parameter | Detail |
|---|---|
| Launched | October 2018 |
| Ministry | Ministry of Petroleum and Natural Gas |
| Target | 5,000 CBG plants by 2023-24 (revised timelines) |
| CBG production target | 15 MMT (million metric tonnes) by 2023-24 |
| Offtake | Oil Marketing Companies (IOC, BPCL, HPCL) committed to purchase |
| Price assurance | OMCs provide assured offtake at floor price |
GOBARdhan (Galvanising Organic Bio-Agro Resources Dhan) — under Jal Jeevan Mission/SBM:
- Converts cattle dung and organic waste into biogas + biofertiliser
- Linked to village-level CBG plants under Gram Panchayats
Progress vs Target (SATAT)
| Year | CBG Plants Target | Plants Commissioned | Gap |
|---|---|---|---|
| 2023-24 | 5,000 | ~600-700 | Significant shortfall |
| 2025-26 | Revised targets | ~1,000 | Below target |
The gap reflects implementation challenges: feedstock aggregation, technology cost, gas distribution infrastructure, and offtake logistics.
The Argument for CBG as an LPG Substitute
Why CBG Can Work at Scale
- India generates 900+ million tonnes of agri-waste annually — most burned in fields, causing air pollution (stubble burning). CBG converts this into clean fuel.
- Rural income generation: A 2,000 kg/day CBG plant creates 5-8 direct jobs and ~50 indirect (feedstock supply chain)
- Biofertiliser co-product: CBG plants produce fermented organic slurry — high-quality biofertiliser that can substitute chemical fertilisers
- Carbon neutrality: CBG is considered near-carbon-neutral — the methane captured from decomposing organic matter would have been released anyway
- Infrastructure compatibility: CBG can use existing CNG/PNG distribution infrastructure — unlike hydrogen, it requires no new pipeline standards
The Comparison with Ethanol Success
The editorial draws parallels with ethanol blending, which reached 15-16% in petrol (E15-E16) by 2025 — ahead of schedule — driven by policy continuity, assured offtake by OMCs, and price discovery. CBG needs a similar policy framework: floor price guarantees, streamlined clearances, feedstock aggregation hubs, and viability gap funding for the first generation of plants.
Challenges and the Path Forward
| Challenge | Solution |
|---|---|
| Feedstock aggregation cost | Cluster-based plants at mandis/sugar mills |
| Technology capital cost | Viability Gap Funding (VGF); MNRE subsidy |
| Gas distribution (last mile) | Piggybacking on CNG station network |
| Regulatory complexity | Single-window clearances under DPIIT |
| Market price uncertainty | Assured OMC offtake at floor price |
