India advances E27 ethanol fuel plans to cut emissions and boost energy security
India is preparing to take a major step in its alternative fuel strategy by planning the rollout of a 27% ethanol blend in petrol, commonly referred to as E27. This initiative follows the country’s earlier success in achieving its 20% ethanol blending target and reflects its continued commitment to reducing fossil fuel dependency.
The Bureau of Indian Standards (BIS) has been tasked with fast-tracking the formulation of quality specifications for the new E27 blend. Stakeholder consultations are scheduled to begin shortly, marking the early stages of what could be a significant transition in the country’s fuel landscape.
At the same time, the Ministry of Road Transport and Highways has directed the Automotive Research Association of India (ARAI) to study necessary engine modifications for vehicles to run efficiently on E27 fuel. This research is vital to ensure compatibility and performance while minimising emissions and technical issues.
Beyond petrol, India is also exploring alternatives for diesel engines. BIS has been asked to establish standards for a 10% isobutanol (IBA)-diesel blend, signalling the government’s broader approach to diversifying the fuel mix. Though promising, this alternative will likely require tailored adjustments in diesel engine systems, depending on the usage scenario.
In a complementary policy move, draft rules have been released allowing the manufacture and registration of vehicles that run entirely on ethanol (E100). Public feedback has been invited to shape the final regulatory framework.
These initiatives are part of India’s broader strategy to enhance energy security, support agricultural economies by boosting domestic ethanol production, and reduce carbon emissions across the transportation sector.
