Will higher ethanol fuels get cheaper? India waives excise duty on E22-E30 petrol – Firstpost

India’s push to reduce oil import dependence has entered a new phase, with the government abolishing excise duty on petrol blended with more than 20 per cent ethanol.

According to a notification issued on Wednesday, petrol containing between 22 per cent and 30 per cent ethanol will be exempt from excise duty. The tax relief for E22, E25, E27 and E30 fuels comes amid growing policy support for biofuels and could pave the way for wider adoption of higher ethanol blends in the coming years.

The move is significant because it follows the recent introduction of fuel-quality standards for higher ethanol blends, suggesting that the government is laying the groundwork for the next phase of its ethanol programme even though it has not formally announced a blending target beyond 20 per cent.

For India, the world’s third-largest oil importer and consumer, increasing ethanol use has become a key part of a broader strategy to improve energy security, reduce foreign exchange outflows on crude imports and create additional demand for agricultural feedstocks used in ethanol production.

Will consumers benefit?

The immediate question is whether the tax exemption will make higher ethanol fuels cheaper for motorists.

While removing excise duty lowers the tax burden on these fuels, there is no guarantee that consumers will see a corresponding reduction in pump prices. Retail fuel prices depend on several factors, including global crude oil prices, refining costs, ethanol procurement rates, state taxes and the pricing decisions of oil marketing companies.

The exemption could nevertheless improve the economics of selling higher ethanol blends and encourage oil companies to expand their availability. Any price benefit for consumers will depend on how much of the tax savings are passed on through retail pricing.

The issue is particularly relevant because the government has previously acknowledged that ethanol is not necessarily a cheaper blending component. Last year, the petroleum ministry said the weighted average procurement cost of ethanol had exceeded the cost of refined petrol.

Push beyond E20

The latest announcement also comes days after India launched E85 fuel, a petrol variant blended with 85 per cent ethanol, for use in flex-fuel vehicles.

Petroleum and Natural Gas Minister Hardeep Singh Puri recently said state-run oil marketing companies would sell E85 at around Rs 20 per litre less than E20 fuel, positioning it as a lower-cost option for vehicles designed to run on high-ethanol blends.

Although the government has repeatedly said no decision has been taken on raising the national blending target beyond 20 per cent, recent policy developments suggest preparations are underway for a future in which higher ethanol blends play a larger role in India’s fuel mix.

India’s ethanol blending journey

India’s ethanol blending programme has expanded rapidly over the past few years and has become one of the government’s flagship energy-transition initiatives.

The National Policy on Biofuels was amended in 2022 to advance the target of achieving 20 per cent ethanol blending in petrol to the Ethanol Supply Year (ESY) 2025-26 from the earlier deadline of 2030.

Public sector oil marketing companies achieved 10 per cent blending in June 2022, five months ahead of schedule. Blending levels subsequently rose to 12.06 per cent in ESY 2022-23, 14.60 per cent in ESY 2023-24 and 17.98 per cent in ESY 2024-25 up to February 2025, according to petroleum ministry data.

The programme has been promoted as a way to reduce reliance on imported oil while simultaneously supporting India’s sugar sector and increasing incomes for sugarcane farmers through greater demand for ethanol production.

Concerns over costs and vehicle compatibility

The expansion of ethanol blending has also triggered debate over its impact on consumers and vehicle performance.

Some consumer groups and vehicle owners have questioned whether higher ethanol content could affect fuel efficiency, particularly in older vehicles not originally designed for such blends.

The issue reached the Supreme Court last year when a petition challenged the nationwide rollout of E20 fuel. The court dismissed the plea after the government argued that the policy had been carefully evaluated and would deliver broader economic and environmental benefits.

The Society of Indian Automobile Manufacturers (SIAM) has said that while E20 may reduce mileage in certain older vehicles, it does not pose a safety risk.

Cost remains another area of concern. According to the petroleum ministry, the average procurement cost of ethanol for ESY 2024-25 stood at Rs 71.32 per litre as of July 2025, including transportation and GST. That has fuelled questions about whether higher ethanol blending can consistently lower fuel costs, even with tax incentives in place.

Bigger biofuel ambitions

The excise duty exemption for E22-E30 fuels is more than a tax measure. It is the latest indication that India is preparing for a future in which ethanol plays a larger role in the transport fuel ecosystem.

With technical standards now in place, higher-blend fuels entering the market and fiscal incentives being extended to support adoption, policymakers appear to be building the framework for the next stage of the country’s biofuel transition.

For a nation that imports the bulk of its crude oil requirements, the stakes are significant. Expanding ethanol use offers the prospect of lower oil import dependence, improved energy security and stronger demand for domestic agricultural output. The latest tax break suggests that India’s ethanol story may be moving beyond E20 sooner than previously expected.
