Ethanol and India’s E20 Policy: Good Intentions, Poor Execution
India is currently witnessing a wave of frustration around the E20 ethanol blending policy. While the nation has successfully hit its target of 20% ethanol in petrol, many drivers are reporting issues—nonavailability of ethanol-free petrol, reduced vehicle performance, and even mechanical problems. Social media has amplified the criticism, with many labeling ethanol blending a “scam” and blaming the government for its rollout.
But here’s the reality: the policy itself is not flawed. The issue lies in its execution. Studying this rollout closely reveals a textbook example of how excellent intentions, when rushed or poorly implemented, can create unintended problems.
Originally, the E20 target was scheduled for 2030, but the government accelerated the rollout to 2025—five years ahead of schedule. Normally, fast policy execution is a boon, helping reduce oil imports and fuel costs. But in this case, E20 has done the opposite: higher costs for consumers, reduced fuel efficiency, and no real choice at the pump.
So, is this a scam? Not at all. Countries like the United States, France, Germany, Brazil, Canada, and Thailand have successfully implemented ethanol blending. The question is: why is it causing controversy in India? Why does a policy designed to save money and boost the economy end up creating problems for citizens and vehicles?
Let’s break it down.
What Is E20 and Why Was It Introduced?
Ethanol blending means mixing ethanol with petrol. E10 has 10% ethanol, E20 has 20%, and so on. Cars and bikes can run on ethanol because it’s combustible. India’s push for E20 aimed to achieve four major goals:
- Reduce Oil Imports – India imports over 85% of its oil. In FY25, oil imports cost $137 billion. E20 could theoretically save $28 billion in foreign exchange.
- Boost Farmer Income – Ethanol is made from sugarcane and rice by-products. By purchasing these crops, ethanol plants can increase farmers’ revenue.
- Lower Pollution – Ethanol burns cleaner than petrol, reducing carbon emissions and helping India meet climate targets.
- Enhance Energy Security – Domestic ethanol production reduces dependence on oil-exporting nations like Saudi Arabia and the UAE, similar to Brazil and the US.
On paper, E20 looks excellent. So why the outrage?
Execution Gaps Behind the Controversy
1. Compatibility Gap
The energy content—or calorific value—of ethanol is lower than petrol. Petrol delivers 32 MJ per liter, ethanol only 21.1 MJ—a 34% drop. Cars running on E20 burn more fuel to cover the same distance.
- For instance, a car that runs 15 km per liter on petrol will drop to about 14.1 km per liter with E20. Over 1,000 km, that’s 4 liters more fuel—or roughly ₹400 extra if petrol is ₹100/L.
- Ideally, E20 should be cheaper to offset this loss, but petrol prices haven’t fallen, leaving consumers paying more.
2. Vehicle Readiness
Ethanol absorbs moisture, which corrodes fuel systems over time. Rubber pipes crack, seals harden, and pumps fail. Engines require stronger pumps, ethanol-proof components, and calibration for E20.
- Car manufacturers need at least 4 years to redesign engines for E20, but the rollout was too fast.
- Even “E20-ready” cars are only partially upgraded, with engines still tuned for E10.
3. Food vs Fuel
Ethanol comes from food crops like sugarcane, maize, and rice. While the government claims only surplus grains will be used, reality is different:
- In 2023, maize-based ethanol accounted for 42% of all ethanol, causing a 5-million-ton shortfall in maize for consumption.
- India had to import 0.9 million tons of maize—a 7,940% increase from the previous year.
Rapid demand spikes from ethanol plants can raise crop prices, defeating the goal of affordable fuel.
4. Insurance Concerns
When E20 was mandated, insurance companies warned that using the wrong fuel could void claims. If an E10 car fails on E20, owners may have to pay the full repair bill—a nightmare scenario for consumers.
5. Water Usage
Producing 1 liter of ethanol requires massive water: 3,630 L from sugarcane, 4,670 L from maize. With states like Maharashtra and Uttar Pradesh already water-stressed, scaling ethanol production adds pressure on resources.
Lessons from Brazil
Brazil offers a blueprint for successful ethanol adoption:
- Gradual rollout – Started with E10 in the 1970s and increased to E27 over decades.
- Flex-fuel vehicles – Over 80% of cars allow drivers to choose petrol, ethanol, or any mix.
- Infrastructure readiness – Consumers have choice, engines are compatible, and supply chains are reliable.
The key takeaway for India: phase the rollout, allow vehicle and infrastructure preparation, and ensure consumers have choice.
Recommendations for India
- Phase E20 rollout to 2030 – Start with E10, move gradually to E20.
- Move to 2G ethanol – Produced from agricultural waste, not food crops, making it sustainable and reducing food competition.
- Give consumer choice – Offer E, E10, and E20 at pumps to avoid trust issues.
- Align policy with ecosystem – Ensure coordination among manufacturers, insurers, and producers before rolling out.
With proper execution, ethanol blending can reduce fuel costs, boost farmer incomes, and strengthen energy security. The policy is not a scam—it’s a lesson in how good intentions need careful planning and execution.
Final Conclusion
E20 has the potential to transform India’s energy landscape. But rushed execution has caused consumer frustration, increased costs, and raised doubts about safety and sustainability. The moral: noble intentions require meticulous implementation. If India follows global best practices, provides infrastructure support, and gradually transitions to 2G ethanol, this policy could become a true success story.
