Biofuels — fuels derived from biological materials (biomass, crops, organic waste) — occupy a critical place in India's energy security and climate strategy. With over 85% of crude oil requirements met through imports (FY 2023-24), substituting a portion of petroleum fuels with domestically produced biofuels reduces the import bill, supports farmers, and cuts greenhouse gas emissions. India's National Biofuel Policy 2018 (amended 2022) and the Ethanol Blended Petrol (EBP) Programme are central exam topics in GS Paper III.

1. Classification of Biofuels

Generation Feedstock Examples Key Concern
1st Generation Food crops (edible sugars, starch, vegetable oils) Sugarcane ethanol, corn ethanol, soybean biodiesel Food vs fuel competition
2nd Generation Non-food lignocellulosic biomass, agricultural residue Rice straw, wheat straw, wood chips, bagasse Conversion technology cost
3rd Generation Algae Microalgae biodiesel High production cost; early stage
4th Generation Engineered organisms / CO2 capture Synthetic biology approaches Largely experimental

India's current focus is predominantly on 1st generation ethanol (from sugarcane and food grains) transitioning towards 2nd generation (lignocellulosic) sources.

2. National Biofuel Policy 2018 (NBP 2018)

The National Policy on Biofuels, 2018, approved by the Cabinet in May 2018, superseded the earlier 2009 policy and is administered by the Ministry of Petroleum and Natural Gas (MoPNG) with MNRE playing a supporting role in technology development.

Key Targets (Original NBP 2018)

Fuel Target Target Year
Ethanol blending in petrol 20% (E20) 2030
Biodiesel blending in diesel 5% (B5) 2030

NBP 2018 — Amendment 2022 (Critical Change)

The National Policy on Biofuels (Amendment), 2022 advanced the E20 target from 2030 to ESY (Ethanol Supply Year) 2025-26 — a five-year acceleration, triggered by India's rapid progress in ethanol blending.

Additional changes in the 2022 amendment:

  • Expanded feedstock basket: sugarcane juice, B-heavy molasses, damaged food grains (wheat, broken rice), corn, and surplus rice
  • Allowed surplus rice from FCI stocks to be used for ethanol production
  • Enabled advanced biofuel projects (2G) to receive financial support under the SATAT and other schemes

3. Ethanol Blended Petrol (EBP) Programme — Progress

India's ethanol blending programme is one of the fastest-moving biofuel transitions globally.

Ethanol Supply Year Blending Rate Achieved
ESY 2019-20 ~5%
ESY 2021-22 10% (achieved June 2022 — 5 months ahead of schedule)
ESY 2022-23 12.06%
ESY 2023-24 14.60%
ESY 2024-25 17.98%
ESY 2025-26 E20 target (20%)

India achieved the 20% ethanol blending milestone (on an aggregate basis) in 2025, representing a landmark in the programme.

Beyond E20: The government is now working towards an E30 target (30% blending) expected to roll out between 2028 and 2030, following a vehicle compatibility roadmap with the automobile industry.

Feedstock for Ethanol Production

Feedstock Route Share in EBP Programme
C-heavy molasses Traditional route; lowest ethanol yield from sugarcane Historically dominant
B-heavy molasses Higher ethanol yield; allowed post-2018 policy Significant share
Sugarcane juice / syrup Direct conversion; best yield Growing share
Damaged food grains (wheat, broken rice) Starch to ethanol; uses FCI surplus Added post-2022 amendment
Corn Starch route; year-round supply Growing importance for supply security

4. Biodiesel Programme

India's biodiesel ambitions have faced significant feedstock challenges.

Feedstock Status
Jatropha curcas Non-edible oil-bearing shrub; promoted heavily in early 2000s; failed due to low yields on marginal lands, long gestation period, and poor returns for farmers
Karanja (Pongamia) Non-edible oil; limited scale
Used Cooking Oil (UCO) Growing feedstock; FSSAI "Turn the Cycle" initiative to channel UCO from restaurants and hotels to biodiesel refineries
Palm Stearin / industrial fats Minor share

India's biodiesel blend rate remains far below the 5% B5 target — projected at only ~0.7% for 2024-25 despite production of ~718 million litres in 2025 (60% increase over 2024). The jatropha promise did not materialise at scale.

5. Sustainable Aviation Fuel (SAF)

SAF is a drop-in aviation fuel made from non-petroleum feedstocks that can blend with conventional jet fuel without aircraft modification.

India has set progressive SAF blending mandates:

Year SAF Blending Mandate
2027 1%
2028 2%
2030 5%

IOCL's AtJ (Alcohol-to-Jet) Plant: Indian Oil Corporation Ltd is setting up an 86,800-tonne capacity AtJ plant at Panipat using LanzaJet technology, scheduled for commissioning in 2028. It will use ethanol as feedstock to produce SAF.

India is also cooperating with Brazil (the world's largest sugarcane ethanol producer) on SAF production and biofuel trade under the framework of the Global Biofuels Alliance (GBA) — launched at India's G20 Presidency summit in September 2023.

6. Food vs Fuel Debate

The diversion of agricultural land and food crops to biofuel production raises ethical and food security concerns:

Concern Counter-argument
Higher crop prices when food grains diverted to ethanol India uses only surplus/damaged food grains (FCI stocks); sugarcane grown specifically as dual-use crop
Land-use competition: biofuel crops vs food crops 2G biofuels use agricultural residue (straw); no additional land needed
Water-intensive sugarcane cultivation AWD techniques and drip irrigation reduce sugar cane water footprint
Indirect land-use change Policy mandates domestic feedstock; no large-scale import of biofuel feedstocks

India's policy specifically guards against food security risks by allowing only surplus and damaged grain, not diverting food from consumption.

7. 2G Ethanol — The Next Step

Second-generation (2G) ethanol uses lignocellulosic biomass (rice straw, wheat straw, bagasse) rather than food crops. This addresses the food vs fuel conflict and also helps solve the stubble-burning problem.

  • IOCL 2G Ethanol Plant, Panipat (Haryana): Commissioned in August 2022; capacity ~30 crore litres/year from paddy straw; first commercial-scale 2G ethanol plant in India
  • This plant uses paddy straw from the Punjab/Haryana region — directly addressing the stubble-burning crisis that causes Delhi's winter air pollution

Exam Strategy

For Prelims:

  • National Biofuel Policy 2018 approved in May 2018; administered by MoPNG
  • Amendment 2022 advanced E20 target from 2030 to ESY 2025-26
  • Blending milestones: 10% achieved in June 2022 (5 months ahead of schedule); 17.98% in ESY 2024-25
  • E30 target: 2028-2030
  • SAF mandates: 1% (2027) → 2% (2028) → 5% (2030)
  • IOCL 2G ethanol plant at Panipat — uses paddy straw; commissioned August 2022
  • IOCL AtJ (SAF) plant at Panipat — 86,800 tonnes; LanzaJet technology; 2028 target
  • Global Biofuels Alliance launched at G20 India (September 2023)

For Mains (GS Paper 3):

  • Frame biofuel answers around three dimensions: energy security (import substitution) + farmer income (price support for sugarcane) + environment (GHG reduction, stubble use)
  • Biodiesel's failure from jatropha is a key lesson: "Policy must be based on proven technology and realistic feedstock economics, not aspirational projections"
  • 2G ethanol from paddy straw kills two birds: reduces stubble burning + diversifies biofuel feedstock — a strong example of integrated policymaking
  • Food vs fuel: India's approach uses surplus/damaged grain — not a food security risk in current context, but needs monitoring as E30 ambitions grow
