India is taking a significant step towards strengthening its energy security and reducing its dependence on imported crude oil. Recently, the government removed the central excise duty on higher ethanol-blended petrol beyond E20. This decision is expected to give fresh momentum to the country’s biofuel programme and promote domestic fuel production.
This move comes at a time when India is rapidly increasing ethanol blending and aims to save foreign exchange by mixing larger quantities of domestically produced ethanol with petrol. It is likely to benefit farmers, distillery companies, the automobile industry, and the environment.
What’s Happening?
The Central Government has completely abolished the central excise duty on petrol blended with 22% to 30% ethanol, namely E22, E25, E27, and E30. According to a notification issued by the Finance Ministry, zero excise duty will apply to these blends, provided they comply with the new IS 19850:2026 standards set by the Bureau of Indian Standards (BIS).
This decision follows the new fuel quality standards issued by BIS in May 2026, which specify ethanol content, octane rating, sulphur limits, and other technical parameters for blends ranging from E22 to E30.
The government believes that promoting higher ethanol blends will reduce crude oil imports, increase domestic energy production, and encourage the adoption of greener fuels.
India’s Ethanol Blending Journey
Over the past few years, India has made remarkable progress in ethanol blending. Under the National Policy on Biofuels 2018, the government had set a target to increase ethanol blending in petrol. Later, in 2022, the policy was amended, and the E20 target was advanced from 2030 to the ethanol supply year 2025-26.
Public sector oil marketing companies had already achieved 10% ethanol blending in June 2022, almost five months ahead of schedule. Since then, blending levels have continued to rise. In the ethanol supply year 2022-23, blending stood at 12.06%, which increased to 14.60% in 2023-24. By 28 February 2025, during the 2024-25 supply year, the figure had reached 17.98%.
India’s current ethanol production capacity is approximately 20-21 billion litres per year, while the estimated demand for the E20 programme is 10-12 billion litres. This means the country has surplus production capacity, which can now be utilised through higher ethanol blends.
The programme is also important for farmers, as increased ethanol production from sugarcane, maize, and other agricultural produce directly benefits the rural economy. Union Minister Nitin Gadkari has repeatedly stated that this model is import-substituting, cost-effective, pollution-free, and indigenous.
Impact on Consumers and Industry
For ordinary consumers, the immediate impact of this decision may be limited because most vehicles currently in use are designed to run on fuel blends of up to E20. Blends of E22 and above will primarily be suitable for vehicles certified under Automotive Industry Standard (AIS) 171.
According to experts, using higher ethanol blends in older vehicles may slightly affect mileage, but it does not pose any major safety risks. For this reason, in September 2025, the Supreme Court dismissed a petition challenging the E20 rollout.
Meanwhile, E85 fuel has also been introduced in India. It contains 85% ethanol and is suitable for flex-fuel vehicles. According to reports, E85 is being sold at around Rs 20 per litre cheaper than E20 and has been introduced at 48 petrol pumps.
For ethanol producers and distillery companies, this policy sends a positive signal, as it increases the scope for utilising surplus production capacity and boosting future demand.
What Does This Mean for Investors?
The excise duty exemption on higher ethanol blends could create significant opportunities across the biofuel value chain. It is likely to drive investment in ethanol production, distillery expansion, agriculture-based feedstock, and related logistics sectors.
Ethanol-producing companies will be able to make better use of their surplus capacity, while farmers may benefit from increased demand for crops linked to the ethanol industry. This is expected to strengthen rural incomes and support agriculture-based industries.
The automobile sector could also benefit, as the importance of flex-fuel vehicles is likely to increase. If the use of higher ethanol blends expands, flex-fuel vehicles could emerge as a new growth segment. In addition, improved energy security, lower import dependence, and greater domestic production could make this policy beneficial for the Indian economy in the long run.
What’s Next?
The excise duty exemption on higher ethanol-blended petrol indicates that India is preparing to move beyond the E20 target and gradually adopt higher blends such as E22, E25, E27, and E30. This will enable better utilisation of the country’s surplus ethanol production capacity and further reduce dependence on imported crude oil.
In the coming years, the government’s focus will remain on increasing the use of ethanol-based fuels, promoting flex-fuel vehicles, and strengthening biofuel infrastructure. The E85 fuel network is also expected to expand rapidly, with a target of reaching 500 fuel stations by the end of 2026 and 5,000 by 2027.
However, the success of this transition will depend on vehicle compatibility, fuel supply infrastructure, and consumer awareness. Overall, this policy could prove to be an important step towards achieving energy self-reliance, promoting cleaner fuels, and supporting sustainable economic development in India.
