India plans 15% isobutanol blending in diesel to advance biofuel drive
India is preparing the next phase of its biofuel strategy by proposing up to 15% isobutanol blending in diesel. The government says the move will strengthen energy security, reduce crude oil imports and expand cleaner fuel use, while building on the successful rollout of the 20% ethanol-blended petrol (E20) programme.
New Delhi: The Centre is preparing the next phase of its biofuel programme by planning to allow blending of up to 15% isobutanol with diesel, a move aimed at reducing India’s dependence on imported fossil fuels and expanding the use of cleaner transport fuels.
Union Road Transport and Highways Minister Nitin Gadkari said ethanol cannot be blended directly with diesel, prompting the government to develop isobutanol from ethanol as a viable alternative, The Mint reported.
“Ethanol can’t be blended directly with diesel, so we’re producing isobutanol from ethanol. Isobutanol can serve as an alternative to diesel,” Gadkari said while outlining India’s roadmap for alternative fuels.
He said the government is working towards permitting a 15% isobutanol blend in diesel, describing it as an important step in strengthening the country’s energy security and clean fuel transition.
According to Gadkari, pilot projects have already shown encouraging results. He said two generator sets have successfully operated on 100% ethanol and isobutanol, demonstrating that engines can be designed to run entirely on these fuels.
Isobutanol is considered a next-generation biofuel because of its higher energy density, better compatibility with conventional diesel engines and lower emissions compared with several traditional biofuels. Policymakers believe its wider adoption could reduce crude oil imports while creating additional demand for domestically produced biofuels.
The minister’s remarks come days after the Ministry of Petroleum and Natural Gas defended India’s E20 ethanol blending programme against claims circulating on social media.
The ministry rejected allegations that ethanol production places excessive pressure on water resources, damages vehicle engines, voids manufacturer warranties or insurance coverage, or harms the environment. It said the ethanol blending programme is backed by scientific research, regulatory oversight and international experience with blended fuels.
The ministry also highlighted that India achieved its target of 20% ethanol blending in petrol in December 2025, ahead of schedule.
According to official estimates, the programme has generated foreign exchange savings of more than ₹1.9 lakh crore, reduced crude oil imports, lowered carbon emissions and increased income opportunities for farmers through higher demand for ethanol feedstock.
