In 2018, the Indian government unveiled an energy roadmap that was as audacious as it was green: a plan to deploy 5,000 large-scale compressed biogas (CBG) plants to convert the nation’s agricultural waste into 15 million metric tons of homegrown fuel. Seven years into the initiative, known as SATAT (Sustainable Alternative Towards Affordable Transportation), the arithmetic of India’s energy transition is failing to add up.
As of January 2026, only 133 plants are functional, producing a mere 926 tonnes per day. This supply crunch comes at a precarious time for the domestic automotive industry. Sales of CNG-powered passenger vehicles have surged, with market share jumping from 6% in 2020 to nearly 20% in 2025. While major manufacturers like Maruti Suzuki and Tata Motors have moved aggressively toward gas-based models, the infrastructure required to fuel them remains stuck in a cycle of hyper-local and systemic bottlenecks.
Compressed Biogas (CBG) is a renewable, eco-friendly fuel chemically identical to the natural gas (CNG) used to power cars and trucks. While standard natural gas is a fossil fuel extracted from the earth, CBG is considered green because it is produced from organic waste that would otherwise be discarded or burned.
The Institutional Hurdle
The primary friction point isn't a lack of technology, but a lack of administrative continuity. Industry analysts note that waste-to-fuel projects often live or die based on the personal enthusiasm of individual city commissioners. “The commissioner may start a project with enthusiasm but then get transferred within two years, leaving the next official without the same commitment to carry it on,” one expert observed during the recent India Energy Week 2026.
This instability is compounded by a fragmented regulatory landscape. Project developers must navigate upwards of eight government departments that rarely coordinate. Charlotte Morton, Chief Executive of the World Biogas Association, noted that policies across India today are very fragmented, preventing many developers from reaching financial close.
Logistical and Structural Strains
Unlike the ethanol sector, which benefits from centralized feedstock, CBG requires coordinating thousands of small-scale farmers across dispersed landholdings. For plants utilizing Municipal Solid Waste (MSW), the challenge is even more granular: inadequate pre-segregation leads to contaminated waste that damages expensive digestion equipment and suppresses gas yields.
Once produced, getting the gas to the pump is the next crisis. Currently, only 15% of functional CBG plants are connected to City Gas Distribution (CGD) networks. The remaining facilities rely on mobile cascades—pressurized cylinders moved by truck—which are expensive and logistically complex. A report by the International Energy Agency (IEA) highlighted that this method increases the fuel’s carbon footprint, potentially defeating the purpose of a green fuel.
The Economics of Waste
The financial viability of these plants is further strained by low utilization rates. While European biogas plants often operate above 80% capacity, Indian facilities frequently hover between 20% and 60% due to seasonal feedstock variability.
Furthermore, a CBG plant is as much a fertilizer factory as it is a fuel station. “CBG is a biological living ecosystem, not just a plant,” explained an executive from BPCL. For every 10 tons of gas produced, the process generates approximately 25 tons of solid manure and 80 tons of liquid waste. Without a robust local market for this Fermented Organic Manure (FOM), plants can become “physically and financially clogged.”
Policy as a Catalyst
Recognizing these gaps, New Delhi has introduced a suite of viability gap funding measures. The Development of Pipeline Infrastructure (DPI) scheme now covers 50% of the cost of connecting plants to the national grid. Similarly, the Biomass Aggregation Machinery (BAM) scheme offers 50% subsidies for procuring collection equipment.
To shore up demand, the government has instituted a mandatory blending mandate, starting at 1% for FY 2025-26 and rising to 5% by FY 2028-29. There is also a push to formalize the by-product market, with a subsidy of Rs 1,500 per metric tonne for quality-tested organic manure.
The Road Ahead
Despite the slow start, industry leaders maintain a posture of realistic optimism. The consensus is that the vision requires a more cohesive national biogas mission to bridge the gap between local waste and the national gas station.
As Charlotte Morton of the World Biogas Association summarized: “The political will and ambition are there. What is required is a coordinated effort to bring everything together.” For India’s automotive sector, the success of that coordination will determine whether its gas-powered future is fueled by domestic waste or remains tethered to imported energy.
