India crossed the 20 percent ethanol blending milestone with petrol in November 2025, roughly two months ahead of the national target. From April 1, 2026, E20 fuel is mandatory across all states and Union Territories. The fuel programme is now looking at its next target, and the number being discussed within the industry is 22 percent blending, or E22. Getting there will require more ethanol than the country’s current production is supplying to oil marketing companies, and more ethanol from sugar means less sugar available to export.

The trade-off is sharp and documented. BMI, a division of Fitch Solutions, published an outlook in April 2026 noting that any push beyond E20 will likely require a formal restriction on sugar exports. Sugar mills and distilleries in the country have a combined ethanol production capacity of nearly 1,000 crore litres per year from sugarcane-based sources alone. In the current supply cycle, oil marketing companies have ordered only 288.51 crore litres of ethanol from sugar factories, less than 29 percent of available capacity.

That number is important because it shows the country’s issue is no longer just one of installed capacity. It is now about allocation, pricing, and policy direction. In other words, India has built enough ethanol-making ability to move beyond older blending levels, but whether that capacity is actually used depends on how much fuel blending the government wants to mandate and how much sugar it is willing to pull away from the food and export chain. Once the blend target rises, the economics of diversion become much more direct.

The gap between production capacity and orders exists because E20 blending targets, now that they have been met, do not require mills to run at full output. If the government sets a higher target, say E22, OMC orders would need to scale up substantially, which would require mills to divert more sugarcane juice toward ethanol instead of sugar.

Grain-based ethanol producers, which use rice and maize rather than sugarcane, have offered 13,040 million litres for the ethanol supply year 2025-26 against the oil marketing companies’ combined annual requirement of around 10,500 million litres. The total industry offer of 17,760 million litres significantly exceeds what OMCs need at current blending levels. Without a raised blending mandate, large portions of that capacity stay idle.

This is where the next phase of the ethanol programme becomes more complicated. At E20, the country can manage with current procurement patterns and not fully stretch either sugar or grain supply. At E22, however, the room for surplus begins to narrow. A higher blend means the system has to decide which feedstocks get priority and under what pricing terms. Grain-based ethanol can absorb some of the pressure, but sugar remains central because of the existing mill-distillery ecosystem and the speed at which cane-based units can respond if incentives are right. So even with idle capacity in the system, moving to E22 is not just a technical switch. It is a policy choice with agricultural and trade consequences.

India has had a cautious export policy on sugar in recent years. In 2022-23, exports were restricted due to a production shortfall. In 2023-24, even after a strong harvest, no exports were permitted. In 2024-25, about 9 lakh tonnes were shipped against the permitted 10 lakh tonnes. In the current 2025-26 season, the government has allowed 15.9 lakh tonnes for export, with over 3.6 lakh tonnes shipped by end of March. If ethanol blending targets are raised further, the government would need to reduce or eliminate this export quota to keep enough sugarcane directed toward fuel production.

That would not be a minor adjustment. Sugar exports are one of the pressure valves the government uses to balance domestic supply, farmer interests, mill cash flow, and global price movements. Restricting exports more tightly to support higher ethanol blending may help fuel policy, but it also means less flexibility in the sugar market. Mills that were expecting export-linked revenue may have to depend more heavily on domestic sales and ethanol procurement. For the government, that means any move toward E22 will likely require tighter coordination across petroleum, food, and agriculture policy, rather than being handled as a standalone fuel decision.

All vehicles manufactured from 2023 onward are built to handle E20 fuel without any modification. Older vehicles require a check of the manufacturer’s compatibility list, available on most OEM websites. Rubber components in older fuel systems, specifically hoses and seals, can degrade faster with higher ethanol concentrations, and some older carburettor-equipped motorcycles are not rated for E20. For cars bought after 2023, E20 is a non-issue. For owners of bikes and cars from before 2020, a check with the manufacturer or a service visit before assuming E20 compatibility is advisable.

That compatibility issue becomes even more relevant if the conversation shifts from E20 to E22. While the current nationwide rollout has already pushed manufacturers and consumers to adjust to E20, any future move upward will bring fresh scrutiny around material durability, calibration, fuel-system wear, and long-term service implications for older vehicles. Newer models are already aligned with present policy, but the older parc remains large, especially in the two-wheeler market. That means future blending increases may not be debated only on fuel-security or sugar-export grounds. They may also reopen questions about how quickly the existing vehicle fleet can safely adapt to even higher ethanol content.
