India is fast-tracking flex fuels, proposing E85 and E100 as automotive fuels beyond the mandatory E20. This shift is prompted by energy supply shocks and ethanol's current cost advantage over petrol, promising enhanced energy security. While requiring vehicle overhauls and sustainable ethanol production methods (e.g., millets, not water-guzzling rice), the author emphasizes this moment as an "inflection point." The industry needs long-term cost competitiveness, but the time for flex fuels is definitively here, urging policymakers to embrace bolder biofuels strategies.
