India Mulls 25% Ethanol Blend as Barmer Refinery Comes Online

TL;DR: India is evaluating a jump to a 25% ethanol‑petrol blend and has just put the Barmer refinery into service, steps that could shave millions of barrels off crude imports and tighten domestic fuel supply.

India’s ethanol programme already trims about 4.5 crore barrels of crude oil each year – roughly 45 million barrels – and saves around ₹1.5 lakh crore in foreign‑exchange outflow. Officials now propose lifting the blend from the current 20% to 25%, a move that would deepen the impact on import bills.

The proposal arrives as the Barmer refinery in Rajasthan begins operations, adding fresh capacity to a network that also includes an expansion at the Numaligarh refinery in Assam. Both projects are part of a broader push to keep Indian refineries running near full throttle without over‑relying on continuous 100% utilization, which the government deems unsustainable.

Higher ethanol content promises to displace more gasoline, but policymakers caution that engine performance, fuel efficiency and vehicle warranty concerns must be addressed. The blend increase would be phased in, allowing manufacturers and fuel stations to adapt.

Domestic refining growth dovetails with efforts to enlarge strategic petroleum reserves, creating a buffer against volatile global oil markets. Recent turmoil in West Asia has underscored the risks of heavy import dependence, prompting India to treat biofuels, renewable power and green hydrogen as strategic assets rather than optional green projects.

If the 25% blend proceeds, the combined effect of reduced crude demand and new refining output could lower India’s exposure to price spikes and supply shocks. The move would also boost demand for domestically produced ethanol, encouraging agricultural and industrial stakeholders to expand production.

Watch for the government’s timeline on the blend increase, the ramp‑up schedule at Barmer, and any policy incentives aimed at ethanol producers as India balances fuel security with environmental goals.
