Fuel Revolution: Pune’s NCL Scientists Develop DME as a Clean, Indigenous Alternative to LPG

Fuel Revolution: Pune’s NCL Scientists Develop DME as a Clean, Indigenous Alternative to LPG Scientists at the CSIR-National Chemical Laboratory (NCL) in Pune have achieved a historic milestone by developing Dimethyl Ether (DME) as a sustainable alternative to LPG. After 20 years of research, this indigenous technology—produced from biomass and methanol—offers a cleaner burn with higher thermal efficiency and zero soot. As global tensions disrupt LPG supplies in 2026, this breakthrough could save India nearly ₹9,500 crore in foreign exchange annually.
