Dimethyl Ether (DME) as a Cooking Fuel Alternative

• Recent disruptions in Liquefied Petroleum Gas (LPG) imports have renewed policy focus on Dimethyl Ether (DME) as a scalable domestic cooking fuel alternative.

About Dimethyl Ether (DME)

• Dimethyl ether (DME), also called methoxymethane, is a colourless, highly flammable gas with a faint sweet odour.
• Combustion: It has a high cetane number of 55–60 and burns virtually without producing soot or particulate matter.
• Physical Property: DME is gaseous at room temperature but liquefies easily under moderate pressure of 5 bar.
• Feedstocks: DME can be synthesised from a wide range of feedstocks, including coal, natural gas, biomass, methanol, and captured CO₂
• Indirect Route: Most common commercial method involves catalytic dehydration of methanol.
• Direct Route: Produces DME in a single catalytic step directly from synthesis gas (syngas).
• CO₂-to-DME: Captured CO₂ reacts with green hydrogen to produce DME.
• Global Leader: China currently leads the world in both DME production and consumption.

Key Applications of DME

• Ozone-friendly aerosol propellant in sprays, adhesives, and cosmetics.
• Chemical feedstock for manufacturing dimethyl sulfate and acetic acid.
• Over-the-counter freeze sprays for skin treatment.
• Environmentally friendly refrigerant (R-E170) for industrial cooling and heat pumps.
• Low-emission diesel alternative for heavy transportation.
• Clean-burning, soot-free cooking fuel.

Advantages of DME as an LPG Alternative

• Self-Reliance: India can produce the entire DME fuel chain domestically by converting high-ash coal and agricultural biomass into methanol.
• Integration: DME can utilise existing LPG cylinders for storage and transportation with minimal infrastructure modifications.
• Efficiency: It yields a 10-15% improvement in heat output compared to conventional LPG burners.
• Cleaner Air: DME combustion generates much lower NOx, SOx, and CO emissions, with almost no particulate matter and smoke.
• Safety: Its non-toxic and non-corrosive nature ensures high safety margins for household cooking and industrial handling.

Limitations of DME as an LPG Alternative

• Energy Density: DME has a lower calorific value than LPG and therefore requires larger fuel volumes for equivalent output.
• Seal Degradation: As a strong solvent, DME causes nitrile rubber (NBR) seals and gaskets in LPG cylinders to swell, degrade, or leak.
• Flame Stability: DME exhibits poorer flame stability and shorter flame height than LPG, requiring specialised burners for safe use.
• Capital Cost: Coal gasification plants require high capital investment, and volatile methanol prices further erode producer profitability.
• Lubricity: As a transport fuel, DME’s low viscosity and lack of lubricity cause premature wear in fuel injection systems.

DME Landscape in India

• Market Size: India’s DME market reached $265 million in 2024, with projections to reach $765 million by 2033.
• Indigenous Process:  CSIR–National Chemical Laboratory (NCL) has developed an indigenous Methanol-to-DME process and plans to scale output to 0.5 tonnes per day.
