Cheaper crude, dearer ethanol: India’s maize bind
2-minute summary
India's aggressive push to achieve its 20% ethanol blending target (E20) by 2025 has triggered a massive agricultural and economic shift. Maize has rapidly become the single-largest feedstock, accounting for nearly half of the ethanol blended into petrol, up from almost nothing in 2021. While intended to reduce crude oil import dependence and conserve groundwater by moving away from water-intensive sugarcane, this policy has created a 'food-versus-fuel' conflict. India has transitioned from a net exporter of maize to a net importer to satisfy distillery demands, driving up domestic maize prices and hurting the poultry and animal-feed industries. Furthermore, with global crude prices falling, the high government-fixed procurement price for maize ethanol (₹71.86/litre) makes E20 fuel more expensive to produce than unblended petrol, presenting a complex economic paradox.
Why it's in the news
The Hindu's August 2026 report highlights how India's transition to E20 fuel has turned the country into a net maize importer for the first time in decades, while falling global crude prices have made maize-derived ethanol economically unviable compared to pure petrol.
Background and context
India launched the Ethanol Blending Programme (EBP) to reduce its heavy reliance on imported crude oil and curb vehicular emissions. Initially, sugarcane was the primary feedstock. However, recognizing that sugarcane alone could not sustainably meet the 20% blending target due to its high water footprint, NITI Aayog and the Ministry of Petroleum and Natural Gas released the 'Roadmap for Ethanol Blending in India 2020-25' in June 2021. This report recommended diversifying feedstocks to less water-intensive food grains, particularly maize. India achieved its E20 target in 2025, five years ahead of the initial schedule. However, this rapid transition has diverted significant agricultural output from food and feed sectors to fuel production.
Constitutional provisions
- Article 48 — Directs the State to organize agriculture and animal husbandry on modern and scientific lines.
- Article 48A — Directs the State to protect and improve the environment, which aligns with the ecological goals of transitioning to biofuels.
Committees and reports
- Roadmap for Ethanol Blending in India 2020-25 — Jointly published by NITI Aayog and the Ministry of Petroleum and Natural Gas, it recommended diversifying feedstocks to food grains like maize to meet the E20 target.
Government schemes
- Ethanol Blended Petrol (EBP) Programme — The core national initiative aimed at blending ethanol with petrol to reduce import bills, lower emissions, and boost the agricultural economy.
- National Policy on Biofuels — Provides the overarching professional framework for biofuel production, categorization of feedstocks, and blending targets in India.

Mains practice: Critically analyze the economic and agricultural implications of India's rapid transition to grain-based ethanol under the Ethanol Blending Programme.
India's early achievement of the E20 blending target in 2025 marks a significant milestone in energy security. However, the shift from sugarcane to grain-based feedstocks, particularly maize, has introduced complex economic and agricultural trade-offs.
**Agricultural and Trade Implications:**
• **Shift in Trade Balance:** India has transitioned from being a net exporter of maize ($764 million in 2022-23) to a net importer (0.9 million tonnes in 2024, primarily from Myanmar and Ukraine) to satisfy distillery demands.
• **Food vs. Fuel Conflict:** Nearly one-third of domestic maize production (127 lakh tonnes) is now contracted for ethanol. This directly competes with the poultry and animal-feed industry, raising feed costs (which constitute 60-70% of their production costs) and driving up domestic maize prices from ₹15,000 to ₹25,000 per tonne.
• **Yield and Resource Concerns:** Although maize is less groundwater-intensive than sugarcane, its low yield (~3.5 tonnes/hectare vs. sugarcane's 80 tonnes/hectare) requires vast land resources, threatening crop diversification.
**Economic Implications:**
• **Viability Paradox:** At a fixed procurement price of ₹71.86/litre for maize-based ethanol, blending becomes economically unviable when crude oil prices fall (around $70/barrel or ₹55/litre), making E20 fuel more expensive than unblended petrol.
• **Industrial Underutilization:** Due to a lack of flex-fuel vehicles and distribution bottlenecks, nearly 450 crore litres of ethanol production capacity remains idle, while sugar mills face diminishing returns due to frozen pricing for sugarcane-based ethanol.
**Conclusion:**
To resolve this bind, India must adopt a flexible pricing mechanism linked to crude prices, promote genuine second-generation (2G) lignocellulosic biofuels, and accelerate the adoption of flex-fuel vehicles to balance energy self-reliance with food security.
Prelims practice questions
Q1. Regarding India's Ethanol Blending Programme (EBP), consider the following statements: 1. Maize has recently emerged as the single-largest raw material for ethanol production in India, accounting for nearly half of the blended ethanol. 2. Grain-based feedstocks (including maize, surplus rice, and damaged grains) contribute to nearly 70% of India's total ethanol production. 3. Sugarcane-based ethanol currently receives the highest government-fixed procurement price among all feedstocks. Which of the statements given above is/are correct?
- 1 and 2 only
- 2 and 3 only
- 1 and 3 only
- 1, 2 and 3
Answer: A. Statements 1 and 2 are correct. Maize accounts for close to half of India's blended ethanol, and total grain feedstocks account for nearly 70%. Statement 3 is incorrect because the government buys ethanol made from maize at a fixed ₹71.86 a litre, which is the highest rate paid for any feedstock, not sugarcane.
Q2. Which of the following reports recommended the diversification of ethanol feedstock to less water-intensive crops like maize to meet India's 20% blending target?
- Shanta Kumar Committee Report on FCI Reforms
- NITI Aayog's 'Roadmap for Ethanol Blending in India 2020-25'
- Kirit Parikh Committee Report on Petroleum Pricing
- Ashok Dalwai Committee Report on Doubling Farmers' Income
Answer: B. The June 2021 report 'Roadmap for Ethanol Blending in India 2020-25' by NITI Aayog and the Ministry of Petroleum and Natural Gas urged a move to less water-hungry crops such as maize because sugarcane alone could not meet the 20% blending target.
Q3. What has been the primary trade consequence of India's rapid shift towards maize-based ethanol production?
- The domestic price of maize has crashed due to oversupply from distilleries.
- India has become the world's largest exporter of maize to Southeast Asian countries.
- The poultry and animal-feed industry has completely substituted maize with sugarcane bagasse.
- India has transitioned from being a net exporter of maize to a net importer of maize.
Answer: D. As distilleries absorbed the domestic crop, India's maize exports collapsed from $764 million in 2022-23 to $201 million in 2024-25. In 2024, India became a net maize importer for the first time in decades, importing around 0.9 million tonnes.
Revision flashcards
- What percentage of India's ethanol is currently produced from grain feedstocks (including maize, surplus rice, and damaged grains) (as of August 2026)? Nearly 70% (with maize alone accounting for close to half of all blended ethanol).
- Why did NITI Aayog's 2021 Roadmap recommend shifting ethanol feedstock from sugarcane to maize? Because sugarcane alone could not meet the 20% blending target, and maize is a faster-growing, rainfed kharif crop that uses less groundwater.
- What is the economic paradox of E20 fuel when global crude oil prices fall to around $70 a barrel? Maize-based ethanol is procured at a high fixed price (₹71.86/litre), making ethanol blending costlier than producing pure petrol when crude costs around ₹55/litre.
- How has the ethanol push affected India's maize trade balance since 2022-23? India transitioned from a net exporter ($764 million in 2022-23) to a net importer (~0.9 million tonnes in 2024, mainly from Myanmar and Ukraine) to meet domestic demand.
- Which domestic industry is in direct competition with ethanol distilleries for maize feedstock? The poultry and animal-feed industry, where feed accounts for 60-70% of production costs.
