About ethanol

The Ethanol Blended Petrol programme is older than most people assume and moved faster than almost anyone predicted. Understanding how it got to E20 explains why the feedstock question, not the blending target, is now the contested one.

01 — THE CLIMB

A decade of going nowhere

For its first decade the programme barely moved. Blending was under 1.5% in 2013-14 and 1.14% the year after: supply was unreliable and administered prices too low to justify building a distillery.

The money arrives

The inflection came after 2018. Interest-subvention schemes financed a wave of new capacity — 368 projects approved — and differential pricing made the and routes worth taking. The National Policy on Biofuels set an E20 target for 2030; by December 2020 the Cabinet had pulled it forward to 2025.

Five months early, then five years early

E10 arrived in June 2022, five months ahead of schedule. E20 followed in 2025-26, five years early, and from 1 April 2026 E20 became the sole standard petrol grade.

Average blending rate by supply yearFIG. 2.1

Line chart of India's average ethanol blending rate rising from 1.5% in 2013-14 to 20% in 2025-26. Key point: E10 was reached in June 2022, five months early, and E20 in 2025-26, five years ahead of the original target. Full data in the table below.

Ethanol supply years run 1 November to 31 October. Years with no published blending figure are omitted, so the horizontal axis is a sequence of reported years rather than an even time scale.

Feedstock share: cane against grainFIG. 2.2

Stacked bar chart of ethanol feedstock shares by supply year. Grain rises from 13.7% of supply in 2020-21 to a peak of 69.1% in 2024-25, and stands at 66.9% in the first half of 2025-26. Key point: the programme stopped being predominantly cane-based between 2022-23 and 2023-24. Full data in the table below.

02 — THE QUIET SWITCH

The programme stopped being about cane

In 2019-20, nine litres in ten came from sugarcane. By 2024-25 grain supplied 69% of the ethanol reaching oil marketing companies — 718 crore litres against 321 from cane. This is the single most consequential fact about E20 and the least discussed.

It relieved pressure on sugar — and transferred it onto maize, damaged foodgrain and surplus FCI rice. India became a net maize importer in 2024 for the first time in decades, and 52 LMT of FCI rice was allocated to ethanol in each of the last two supply years.

Capacity now runs at about 2,019 crore litres across 478 units — roughly double what E20 blending needs.

03 — IN CONTEXT

India against the world's blenders

World fuel ethanol production, 2024FIG. 2.3

Horizontal bar chart of fuel ethanol production by country in 2024. The United States leads with 16.2 billion US gallons, 52% of world output, followed by Brazil at 8.8 billion (28%). India is third with 1.63 billion gallons, 5% of the world total. Key point: only Brazil blends deeper than India, and it does so on a fifty-year-old programme with a flex-fuel fleet. Full data, including blend mandates, in the table below.

Only Brazil blends deeper than India. Brazil's programme is fifty years old, built on a flex-fuel vehicle fleet and a cane sector with roughly twice India's yield per hectare, and it moved to E30 in August 2025.

The United States blends less but produces far more — 52% of world output, almost entirely from maize. That is why American food-versus-fuel arguments read so similarly to India's newest ones.

India cannot copy Brazil directly: Brazilian mills flex between sugar and ethanol on a market parity price, while India's ethanol prices are administered. India's flexibility is policy — switching cane-juice and B-heavy allowances on and off — not price.
