Bureau of Indian Standards notified new standards for E22, E25, E27, and E30 ethanol-blended petrol fuels under IS 19850:2026.
E30 fuel contains 30% ethanol blended with petrol, and India aims to achieve 30% ethanol blending by 2030 under the National Policy on Biofuels, 2018.
BIS also released IS 18698:2026 standards for Dimethyl Ether (DME) blended Liquefied Petroleum Gas (LPG), replacing the 2024 standard.
Dimethyl Ether (DME) is a clean-burning synthetic fuel used as an alternative to LPG, and China accounts for nearly 90% of global DME production capacity.
BIS develops standards for petrol, biofuels, hydrogen, biodiesel, and green fuels to ensure fuel quality, safety, and reduced environmental impact.
