India has finalized regulations to legally authorize 100% ethanol — E100 — as a vehicle fuel, with Road Transport Minister Nitin Gadkari signing the order on June 12, 2026. The move comes as the country, which imports roughly 85% of its fuel, faces heightened supply risks from the US-Iran conflict closing the Strait of Hormuz.
Why the push for E100 now
India’s fuel import bill hit 22 lakh crores last fiscal year, and the closure of the Strait of Hormuz — a key chokepoint for Gulf oil and gas — has made those shipments unreliable. In May 2026, the US supplied 630,000 tonnes of LPG and 900,000 tonnes of LNG to India, exceeding combined deliveries from all Gulf states by 60%. That emergency supply underscores how quickly external shocks can scramble energy flows.
The new E100 regulation is designed to cut reliance on foreign crude by turning domestic agricultural feedstocks — sugarcane, corn, surplus grains — into fuel. No hard targets were announced alongside the signing, but the policy creates a legal framework for stations to sell pure ethanol and for automakers to certify cars for it.
Automakers line up ethanol-ready models
Several major car and motorcycle makers are already developing vehicles that can run on E100. Maruti Suzuki, Hero MotoCorp, Toyota, Hyundai, and MG have confirmed ethanol-ready models in the pipeline. Some have already launched, and others are expected within six weeks, according to the companies.
That timeline suggests at least a few commercial E100 vehicles could hit Indian roads before the end of July 2026. Hero MotoCorp, the world’s largest two-wheeler maker by volume, has been testing flex-fuel engines for years and is likely to be among the first with a mass-market bike.
What E100 means for farmers and the fuel bill
The government has long pushed ethanol blending — first E10, then E20 — but E100 is a leap. A car running on pure ethanol gets lower mileage per litre than one on petrol, but the fuel burns cleaner and comes from domestic farms. For India’s agricultural economy, the policy creates a guaranteed buyer for crops that might otherwise rot or sell at low prices.
Gadkari, who has been the political face of the ethanol push, has said repeatedly that cutting the import bill is a national security issue. The 22 lakh crore figure — roughly $260 billion — is a heavy weight on India’s trade deficit. Even a small shift to domestic biofuels reduces that outflow.
The US-Iran conflict accelerating the Strait of Hormuz closure may have given the policy extra urgency. India normally gets much of its LPG and LNG from Qatar, Saudi Arabia, and the UAE. When those supplies are threatened, the search for homegrown alternatives intensifies.
What the regulation does not address is infrastructure. Pumps need to be retrofitted to dispense E100; existing stations that sell E20 may not be compatible. The Ministry of Road Transport and Highways has not yet detailed a rollout plan for retail outlets. That will be the next bottleneck — and the next deadline for the government.
