India's Ministry of Road Transport and Highways is proposing an amendment to vehicle rules that would permit 100% ethanol (E100) fuel blending [1, 2].
The move aims to reduce the nation's reliance on foreign energy sources. India currently depends on imports for approximately 90% of its oil [4], making the economy vulnerable to price shocks and global supply disruptions.
This proposal expands the current ethanol mandate, which requires a 20% blend (E20) [2]. While the government has previously notified standards for petrol containing up to 30% ethanol [2], the new draft pushes the limit to a full 100% [1].
The initiative is part of a broader strategy to improve energy security during an ongoing global energy crisis [2, 4]. By shifting toward domestic ethanol production, the government hopes to stabilize fuel costs and lower the volume of crude oil entering the country.
Earlier this month, the ministry opened the draft rule for public consultation [3]. The public has 30 days to provide feedback on the proposed changes before they are finalized [3].
There are varying reports regarding the specific target for high-blend fuels. Some reports indicate a push for E100 [1], while others suggest policymakers may be shifting focus toward E85 [5]. The current draft under consultation specifically addresses the permission of E100 fuel blending [1, 3].
“India currently depends on imports for approximately 90% of its oil”
This policy shift represents a significant escalation in India's energy transition. By moving from E20 to potentially E100, India is attempting to decouple its transport sector from the volatility of the global crude oil market. However, the success of this transition depends on the scalability of domestic ethanol production, and the ability of vehicle manufacturers to produce engines compatible with high-ethanol blends without compromising performance.
