The Story

Last week, India quietly did something it has never done before.

At a handful of stations across the country, a new fuel appeared on the pumps. This was a blend containing 85% ethanol and just 15% petrol also known as E85.

And if things go as planned, it could completely change how India powers its vehicles.

But here’s the thing. India has only just started getting used to E20 fuel, which became mandatory across petrol pumps in April this year. So how are we already talking about jumping from an E20 blend we’re still getting accustomed to, to a much higher E85?

To understand that, you’ll need to rewind about two decades.

You see back in 2001, the government launched a simple pilot to blend just 5% ethanol into petrol. The idea was that India imports enormous quantities of crude oil. But ethanol can be made domestically from sugarcane. So why not mix the two and reduce the import bill?

This policy existed on paper for years but it didn’t take off for a few reasons.

And the sugar mills had little reason to cooperate. Selling ethanol to oil companies was less profitable than making sugar. So blending rates moved between 0.1% and 1.5% for over a decade.

All that changed in 2014. The government stepped in with a set of reforms that changed the economics behind blending. It fixed a guaranteed price that distilleries would be paid for ethanol, so producers knew exactly what they’d earn before investing.

Instead of only allowing ethanol from molasses (the leftover syrup from sugar refining), producers could now use sugarcane juice directly and even damaged food grains.

Blending climbed from 1.5% in 2014 to 10% by 2022, five months ahead of schedule. Seeing how quickly adoption picked up, the government brought forward the E20 target from 2030 to 2025. India hit that milestone too, delivering significant benefits along the way, including foreign exchange savings of nearly ₹1 lakh crore that would otherwise have gone towards crude oil imports, and a reduction of 544 lakh metric tons of CO2 emissions since ethanol-blended fuel burns cleaner.

But that’s also when the problem began.

Because the government has been aggressively pushing a clean energy transition, India’s distillery sector rapidly expanded its ethanol production capacity to roughly 2,000 crore litres, helped by government incentives to scale up.

But here’s the thing. Demand never quite caught up.

For context, the E20 petrol available today only needs about 1,016 crore litres of ethanol every year. Even if you add non-fuel demand from medicines, sanitisers, alcoholic beverages and industrial solvents, India’s total ethanol requirement stands at roughly 1,350 crore litres. In other words, we now have more production capacity than we currently know what to do with.

And that creates a problem as the industry is sitting on unused capacity built with government support. So naturally, the excess ethanol has to go somewhere.

You can’t really blend it with diesel because the two fuels are molecularly different and tend to naturally separate over time. Ethanol also burns differently and has lower energy content, which can affect engine performance and fuel systems designed for diesel. Which is why the government is exploring alternatives like isobutanol, which may work better with diesel blending. But that’s still in the early stages of testing. That simply means for now, diesel remains outside the ethanol story.

Which leaves only one fuel where ethanol can scale meaningfully: petrol.

That’s why last Friday, India inaugurated 48 outlets across the country that will sell E85.

Now we know what you’re thinking. There’s no way my car, bike or scooter will run on this fuel.

And you’d be right.

Unlike E20, E85 requires an entirely new ecosystem of vehicles, infrastructure and supply chains. Most vehicles on Indian roads today simply aren’t built for it.

But the government isn’t trying to push E85 onto every vehicle owner all at once. Instead, the focus is on flex-fuel vehicles, which can run on ethanol blends ranging from E20 to E100, without locking consumers into a single fuel blend. Major automakers like Hero MotoCorp and Maruti Suzuki have already begun rolling out flex-fuel prototypes and production models designed for the Indian market.

But before people like you and I begin using these vehicles, there’s still a lot to figure out. How do they perform in real-world conditions? How reliable are they? What does maintenance look like? And how do they hold up after years on Indian roads?

Those are questions most private buyers would rather let someone else answer first.

Which is exactly why some of these new vehicle models, like the Maruti Wagon R Flex Fuel, are currently being offered only to fleet operators and cab aggregators like Ola and Uber, not private buyers. At least not yet.

And honestly, that makes sense.

India has used this playbook before. When electric vehicles were still expensive and charging infrastructure was patchy, companies like Tata Motors first built demand through fleet operators. Cabs clocked enough kilometres to make the economics work, even when the broader ecosystem wasn’t quite ready.

The same logic could apply to E85. Fleet vehicles can rack up in two or three years the kind of mileage a private car takes a decade to cover. By the time a Wagon R Flex Fuel retires from a cab fleet, manufacturers would have gathered years of real-world data on engine wear, fuel system performance and long-term reliability.

In other words, the risk gets absorbed by commercial operators who understand vehicle economics, not everyday consumers who just want their car to work.

This could also meaningfully increase ethanol demand as fleet vehicles don’t just clock more kilometres, they burn through more fuel too. A cab running on E85 all day moves far more ethanol than a dozen privately owned cars. So you could say that the fleet strategy isn’t just about testing the fuel. It’s also about creating demand.

But that doesn’t mean the plan comes without trade-offs.

Even though ethanol blending is promoted as a cleaner fuel that saves India’s foreign exchange reserves, more ethanol also means more feedstock, much of it coming from water-intensive crops like rice, maize and sugarcane. To put that in perspective, producing just one litre of ethanol from rice can consume around 10,000 litres of water.

And suddenly, the benefits of lower crude imports and cleaner fuel don’t look as straightforward, especially at a time when monsoons have become increasingly unpredictable.

Then there’s the economics of actually using E85. Right now, E85 is available at only 48 fuel stations. But the plan is to expand that to 500 stations by the end of the year and 5,000 by 2027.

Now sure, E85 is priced roughly ₹20 per litre cheaper than regular petrol. But ethanol also has lower energy density, which means vehicles may need to consume more fuel per kilometre at higher blends. So while the upfront fuel cost may look cheaper, the long-term economics may not be as clear-cut.

So while reaching E20 itself felt ambitious, today, the conversation has already shifted to what comes after it. But for now, we’ll just have to wait and see how this plays out.

Until next time…
