In response to the ongoing energy crisis driven by geopolitical tensions in West Asia, India's government is exploring the adoption of E100 fuel blending and flex-fuel vehicles. Senior officials, including Sujata Sharma from the petroleum ministry, announced that blending ethanol in aviation fuel has been officially permitted, creating a legal framework for sustainable aviation fuel (SAF) derived from used cooking oil or ethanol. E100, which consists of nearly 100% ethanol, and flex-fuel vehicles, capable of using various mixtures of ethanol and petrol, are seen as viable solutions to reduce the country's reliance on imported crude oil. However, transitioning to E100 requires significant modifications to vehicle systems due to ethanol's corrosive properties. The government is also granting regulatory exemptions to promote alternative fuels across industrial sectors and has implemented an export ban on ammonium nitrate to ensure stable coal production. Ongoing stakeholder consultations aim to facilitate the adoption of these initiatives, with timelines dependent on the readiness of automobile manufacturers and petroleum refiners.
