The Indian government is moving forward with plans to introduce blended diesel and commercial liquefied petroleum gas, aiming to reduce reliance on imports and boost energy security amidst geopolitical tensions.
The Bureau of Indian Standards (BIS) is finalizing specifications for diesel blended with 10% iso-butyl alcohol (IBA), with a standard expected to be published by June 15, 2026.
Separately, the government is preparing final standards for dimethyl ether (DME)-blended LPG for commercial use by May 15, with a revised benchmark to be notified after consultations.
Blended LPG is being considered only for commercial applications, while household LPG cylinders will continue with conventional fuel mixes.
The draft standard for IBA-blended diesel was prepared by a working group led by Bharat Petroleum Corp executive Dr Bharat Newalkar, based on fuel-characterization studies by leading oil marketing companies.
India already has a benchmark for blended LPG covering household, commercial, and industrial uses, but it has not been implemented.
