The Centre has clarified that there are no immediate plans to introduce E-25 petrol, emphasizing that the current ethanol blending level of E-20 will be maintained. This decision will be based on scientific testing and technical validation, as reported. NDTV highlighted that E-20 petrol, in use for over two-and-a-half years after rigorous testing, does not raise concerns.
The ongoing discussions regarding the impact of higher ethanol blending on vehicle performance and fuel efficiency have prompted this clarification. The shift to ethanol-blended petrol has been implemented gradually, ensuring a smooth transition. With approximately 20 crore two-wheelers and 20 lakh four-wheelers already using ethanol-blended fuel, the adoption has been significant.
In a recent development, the government issued a detailed 10-point clarification on ethanol blending, emphasizing that up to 20% ethanol in petrol is backed by scientific research, global practices, and regulatory measures. Addressing misconceptions, the ministry refuted claims about the excessive water consumption in ethanol production, highlighting the use of surplus rice for ethanol manufacturing.
The ministry further explained that ethanol distilleries typically utilize 3-5 liters of processed water per liter of ethanol, with a growing trend towards Zero Liquid Discharge systems for water recycling. Notably, maize, a key component in over 40% of the ethanol supply, requires less irrigation compared to paddy and is encouraged through higher minimum support prices. Dismissing concerns about E-20 being an untested fuel, the government pointed out the long-standing global use of ethanol-blended fuels.
