Bioenergy Growth in India

Recent developments show India’s strategic push to scale up bioenergy sectors such as Ethanol, Compressed Biogas (CBG), and Biomass. This move aims to reduce dependence on fossil fuel imports and strengthen energy security amid global supply disruptions and price volatility. Government policies and financial incentives have played very important roles in accelerating production and adoption of these renewable energy sources.

Ethanol Blending Programme Success

India’s Ethanol Blending Programme (EBP), started in 2003, has surpassed the 20% blending target ahead of schedule. Supportive policies like the National Biofuel Policy 2018, GST reduction, and interest subvention schemes boosted growth. Ethanol supply rose from 38 crore litres in 2013-14 to over 1,050 crore litres by 2025-26. This shift has saved foreign exchange worth ₹1.63 lakh crore and supported farmers with ₹1.44 lakh crore income. Feedstock diversification from molasses to sugarcane juice, surplus rice, and maize has been crucial.

Emergence of Compressed Biogas (CBG)

CBG production is gaining momentum as a natural gas substitute. It utilises agricultural residues, cattle dung, and organic waste. The SATAT initiative launched in 2018 aims for 5,000 CBG plants with 15 million tonnes annual production. As of March 2026, 201 plants are operational and 319 under construction. Government schemes provide financial aid and infrastructure support to boost the sector’s viability.

Biomass and Co-firing in Thermal Power

Biomass densification into pellets and briquettes is promoted to replace coal. The SAMARTH Mission mandates 5% co-firing in thermal plants from FY 2025-26. This could create a biomass demand of 150 million tonnes yearly. Price benchmarking and assured demand signals have improved market stability. Further incentives are needed for sustainable growth.

Policy Interventions and Future Steps

Key policy interventions include pricing mechanisms, financial assistance, and infrastructure development. The government plans to expand ethanol blending, promote Flex Fuel Vehicles, and test new biofuels like Iso Butanol and DME. Increasing biomass and biogas use in rural areas to replace LPG is also a priority.

2. Key biofuels – Ethanol, Compressed Biogas (CBG), and Biodiesel contribute to diversified domestic energy sources.
3. Ethanol Blending Programme (EBP) achieved 20% blending target early, saving ₹1.63 lakh crore in foreign exchange and substituting 277 lakh tonnes of crude oil.
4. Government policy interventions – National Biofuel Policy, pricing mechanisms, GST reduction, financial incentives, and infrastructure support.
5. Biofuels enhance economic resilience by supporting farmers’ income and reducing inflationary pressures from fuel price shocks.
6. Challenges remain in feedstock availability, technology adoption, and scaling biodiesel; need for sustained policy support and innovation.

2. Examine the challenges and opportunities in scaling up Compressed Biogas production in India and its impact on sustainable development. [GS-III-Environment & DM]

1. Opportunities – Utilizes agricultural residues, cattle dung, municipal organic waste; reduces methane emissions and waste management issues.
2. SATAT initiative targets 5,000 plants with 15 MMT annual production; 201 plants commissioned, 319 under construction as of 2026.
3. CBG serves as a clean fuel for transport, industry, and city gas distribution, aiding energy diversification and rural employment.
4. Challenges – Feedstock collection and aggregation, financial viability, infrastructure development, and market creation.
