India is now focusing on isobutanol blending with diesel as part of its biofuel strategy, following unsuccessful ethanol-diesel trials. Isobutanol (C₄H₁₀O) is a four-carbon alcohol with higher energy density than ethanol, making it more compatible with diesel. It is less hygroscopic, which reduces risks of corrosion in pipelines and engines. Trials by the Automotive Research Association of India (ARAI) are underway for 10% isobutanol–diesel blends, and its use is also being studied in CNG–isobutanol flex-fuel options for tractors. This initiative supports the National Biofuel Policy 2018, aiming to reduce oil imports, enhance farmer incomes, and promote sustainable energy solutions.
