Blended Diesel on the Horizon: India Exploring Isobutanol as a Fuel Additive

The Indian government has successfully rolled out 20% ethanol-blended petrol (E20) across the country, achieving this goal ahead of the initially set deadline of 2030. Building on this, the government is now preparing to introduce blended diesel. However, instead of using ethanol directly, the focus is on using isobutanol, which is derived from ethanol, as an additive.

Previous attempts to blend ethanol with diesel were unsuccessful. Consequently, the government is now experimenting with isobutanol, which is produced from ethanol, to blend with diesel. This process is currently in an experimental phase, as confirmed by Union Minister for Road Transport and Highways, Nitin Gadkari, in a recent announcement.
