ynsugar Analysis Team：As the India ethanol blending roadmap enters its next phase, the story is no longer about hitting a target…

An in-depth look at India’s transition from E20 to flex-fuel vehicles, E85, and E100 — and what it means for energy security, farmers, and the global sugar industry.

A Milestone Reached Five Years Early

India’s ethanol blending story is no longer about hitting a target; it is about defining the next frontier. The program achieved a monumental milestone when India successfully hit its 20% ethanol blending target (E20) in 2025, a full five years ahead of the original 2030 deadline.

As of April 2026, all petrol sold across India must contain 20% ethanol. This rollout marks a pivotal shift in India’s energy strategy, transforming the nation from a fuel importer into a bio-energy powerhouse.

The scale of the transformation is striking. India’s ethanol production capacity has skyrocketed from under 2 billion liters in 2014 to nearly 20 billion liters, far exceeding the 11 billion liters required for the E20 mandate.The Prime Minister has publicly cited the import-substitution impact of the programme in Parliament, with 4.5 crore barrels of crude avoided through E20 blending, by ISMA’s reckoning— the figure that frames the conversation about what India should do next.

In a recent interaction with Autocar Professional, Deepak Ballani, Director General of the Indian Sugar and Bio-energy Manufacturers Association (ISMA), laid out a clear roadmap for the post-E20 era: a measured technical step to E22 in the near term, decisive policy action on flex-fuel vehicles, and a long-term vision of E85 and E100 as mainstream pump options.

The Numbers Behind the Achievement

The economic and rural-development dividends of the Ethanol Blended Petrol (EBP) Programme are substantial. According to official disclosures and ISMA data:

Foreign Exchange Savings: Over the past 11 years, ethanol procurement has saved ₹1.40 lakh crore in foreign exchange and reduced crude imports by 238.68 lakh metric tons.
Farmer Empowerment: Ethanol procurement through 2025 earned farmers ₹1.18 lakh crore. By providing a guaranteed market for surplus crops (sugarcane and maize), it has effectively turned India’s farmers from Annadatas (food providers) into Urjadaatas (energy providers).
Climate Impact: E20 blending has resulted in a net reduction of approximately 832 lakh metric tonnes of CO2 emissions, advancing India toward its Net-Zero by 2070 goal.

Key Stat: Maize-based ethanol production grew from 0% in 2021–22 to 42% in 2026, showcasing a remarkable diversification of feedstock.

The government has also moved aggressively to dispel safety concerns. Dispelling misinformation and false narratives surrounding ethanol-blended fuel, Shri Puri emphasized that there has not been a single case of engine failure or breakdown reported since E20 became a base fuel over the last 10 months.

The Problem of Plenty: Why India Must Move Beyond E20

Success has, paradoxically, created its own pressure point. India’s ethanol blending programme is at a crossroads. With production capacity running at roughly double the current consumption level, and global crude prices surging past $110 a barrel amid the war in the Middle East, the Indian Sugar and Bio-Energy Manufacturers Association (ISMA) is making a pointed case: the country must move beyond E20, and it must create the right policy environment for flex-fuel vehicles to scale.

The math is stark. India currently has the capacity to produce nearly 2,000 crore litres of ethanol annually, with an additional 400 crore litres of capacity set to come online next year. Against that, consumption at the E20 blending level stands at approximately 1,100 crore litres, meaning only around 50 percent of installed capacity is being utilised.

As Ballani put it bluntly in an interview with ANI, “Today we have the overcapacity of ethanol and the consumption is limited to only 20%,” he said, noting that low allocation to distilleries has impacted viability in several states.Without a calibrated next step, the surplus risks undermining the financial health of the very distilleries and sugar mills that made the E20 milestone possible.

ISMA’s Two-Track Pathway

Track 1: A Measured Step to E22

Rather than an abrupt leap to higher blends, ISMA is advocating for a low-friction interim step. Rather than a leap to E27, ISMA is advocating a measured step to E22 as an immediate interim measure. Balani argues the transition is technically straightforward, vehicles that are E20-compliant, mandatory for all new vehicles sold after 2023, can handle higher blends without recalibration.

Ballani drew on international evidence to make the case: “From E20 to E22 should not be a problem. There is scientific evidence. There are some tests which have been done by ARAI also,” he said, drawing on Brazil’s experience where E20-compliant vehicles comfortably absorbed blends of 22–25 percent.

The commercial logic is equally compelling for the industry: Moving from E20 to E22 would immediately absorb an additional 150 crore litres of ethanol.

Track 2: Mainstreaming Flex-Fuel Vehicles

The bigger strategic prize, however, lies in vehicle technology. ISMA’s longer-term vision is not just about incremental blending hikes, it is about establishing flex-fuel vehicles as a mainstream alternative powertrain, much as Brazil has done, where 90 percent of the fleet is now flex-fuel. According to the latest industry data from ANFAVEA (the Brazilian Association of Automotive Vehicle Manufacturers) for the full year of 2025, flex-fuel vehicles accounted for 74.4% of all new light vehicle registrations.

For India to replicate that trajectory, Ballani is unambiguous about the prerequisites. For that to happen, Balani identified two non-negotiables: competitive pricing for E100 fuel, and an end to the cost premium on flex-fuel vehicles over equivalent ICE models.

Automakers appear ready. Deepak Ballani, director general of ISMA, noted that the industry currently has surplus ethanol capacity of over 450 crore litres. With E20 in place, he believes that flex-fuel or flex-fuel hybrids are the next logical step, as carmakers and two-wheeler companies have already shown prototypes of their flex-fuel vehicles. “What is needed now is the right policy framework to get these vehicles on the road,” he said.

The Tax Question: GST Rationalisation as the Catalyst

A central — and so far unresolved — policy lever is taxation. ISMA has argued that India’s GST architecture currently penalises the very clean-technology pathway the government is trying to encourage.

“For a clean technology, for example, EV, if the GST is 5%, why can’t we extend the same GST for even the flexi-fuel vehicle? Because even flexi-fuel and strong hybrid are clean technology vehicles.” Currently, GST on flexi-fuel and strong hybrid vehicles is around 18%.

The same logic, ISMA argues, applies to the fuel itself. “On the E85, or E100 fuel, the GST could be brought down from 18% to 5% which will make E100, E85 slightly cheaper than the normal petrol and will enhance the acceptance by the consumers,” he said.

This view is shared by the auto industry. Tarun Gulati of SIAM has pointed to the Brazilian playbook: “In Brazil, there is a law that says ethanol [E100] should be 33% cheaper compared to the gasoline with 30% ethanol blend [E30]. This naturally drives the cost-conscious consumers to choose E100.”

The E85 and E100 Roadmap Takes Shape

The regulatory machinery is already moving. Following this, India is now advancing toward E85, higher blends, and even 100 per cent ethanol (E100) initiatives for future vehicles. As of April 1, 2026, India has officially mandated nation-wide E20 fuel.

The draft rules for E85 were disclosed by a senior government official, indicating that the government will “very soon” issue the plan on the roll-out of Ethanol 85 (E85). Draft regulations will be notified very soon. There is consensus within the government.

The draft notification goes further than fuel grades alone. Beyond E85 and E100, the notification also proposes new fuel classifications. The petrol description will change from E10/E to E10/E20, while E85 and E100 are explicitly included in the regulatory framework. Biodiesel references will be updated from B10 to B100. The draft also standardises emission-testing parameters and technical terminology.

Infrastructure readiness will be the make-or-break factor. Fuel stations will also require separate storage tanks and dedicated dispensing mechanisms for E85 alongside regular and E20 petrol. If trials proceed as planned, initial testing could begin as early as December 2026.

What About the Existing Fleet?

The most legitimate consumer concern around higher blends is what happens to the cars already on the road. The push toward E20 has triggered concerns from consumers, especially owners of older vehicles, who worry about mileage drops, engine wear and the possibility that damage from higher ethanol blends may not be covered under warranty. These worries have been amplified by user manuals in some older models that caution against using fuel with more than 10% ethanol.

Independent reporting suggests the concerns aren’t entirely unfounded. Autocar India’s own tests, however, recorded drops of up to 12 percent on older or less optimised vehicles on the E10-to-E20 transition, a gap that Balani did not fully contest, acknowledging that older vehicles and engine calibration are real variables.

ISMA’s proposed mitigation is a retrofit solution. For the older vehicle parc, the segment most vulnerable to higher blends, Ballani pointed to a flex-fit retrofit kit tested with IIT Delhi as a potential solution, though it must be noted that this project is still at the pilot stage.

The environmental case for going further is, however, robust. A study by the Indian Institute of Science (IISC) says that flex fuel vehicles can significantly reduce well-to-wheel greenhouse gas (GHG) emissions, particularly when using high-level ethanol blends like E85 or higher.

Energy Security in a Volatile World

The geopolitical context has sharpened the urgency. The West Asian conflict highlights the strategic vulnerability of relying on the Strait of Hormuz. Scaling up ethanol acts as a buffer against volatile international crude prices.

This is precisely why ethanol is being positioned not as a long-term replacement for electric mobility, but as a pragmatic bridge. Ethanol as a Pragmatic “Drop-in” Fuel: India cannot replace its entire internal combustion engine (ICE) vehicle fleet immediately, making ethanol a practical transition fuel. Ethanol acts as a “drop-in” fuel that works with existing engines. Adoption of E20, E30, E100 and Flex-Fuel Vehicles (FFVs) enables immediate decarbonization of transport while reducing crude oil imports.

The Ministry of Petroleum has also outlined the phased trajectory. The Ethanol Blending Roadmap (2020–25) has laid a strong foundation, and the successful rollout of E20—five years ahead of target—demonstrates both industry readiness and consumer acceptance. The country will now gradually scale towards E25, E27, and E30 in a phased, calibrated manner with the support of BIS standards and fiscal incentives.

And in a development with implications well beyond road transport, the government has allowed ethanol blending in Aviation Turbine Fuel (ATF) to boost Sustainable Aviation Fuel (SAF) usage.

The Risks That Cannot Be Ignored

A credible roadmap must also acknowledge the genuine challenges. The diversion of food crops for ethanol production raises concerns about food security and inflation. The cultivation of water-intensive crops such as sugarcane may exacerbate water scarcity in already stressed regions. In addition, the dependence on monsoon conditions introduces uncertainty in supply. The lack of adequate infrastructure, including storage and transportation facilities, remains a bottleneck. There are also concerns regarding vehicle compatibility, as older vehicles may not perform efficiently with higher ethanol blends.

This is why the second-generation (2G) ethanol agenda matters so much. 2G ethanol refineries in Panipat and Numaligarh are converting agricultural residues like parali and bamboo into ethanol, providing a win-win solution for clean fuel, pollution control, and farmer income. Scaling these technologies is critical to addressing both the “food vs. fuel” debate and northern India’s seasonal stubble-burning crisis.

The Outlook: Could 2026 Be the Tipping Point?

Ballani is cautiously optimistic that the policy environment is about to shift decisively. “The government is looking at how to really increase the consumption of ethanol, and how to reduce the dependence (on crude imports). I believe the government will, in 2026, take some concrete steps to increase the consumption of ethanol,” he said.

His prescription is a coordinated two-front push. The pathway ISMA is advocating is a two-track one: a near-term, low-friction move to E22 for the existing fleet, combined with a decisive policy push on GST, vehicle pricing parity, and CAFÉ credits, to make flex-fuel vehicles commercially viable at scale.

For policymakers, the stakes extend well beyond the sugar sector. A successful post-E20 transition would simultaneously address surplus capacity in distilleries, strengthen rural incomes, reduce India’s exposure to volatile crude markets, support climate commitments, and give domestic automakers a clear technology runway in a world where powertrain choices are fragmenting rapidly.

The E20 milestone proved that India can execute at scale and ahead of schedule. The question now — for the government, for OEMs, for fuel retailers and for consumers — is whether the country can build on that momentum and turn ethanol from a blending component into the cornerstone of a genuinely indigenous, future-ready mobility ecosystem for a Viksit Bharat.
