Dimethyl-Ether (DME)


A Non-Renewable Fuel

Although chiefly used as an aerosol propellant in the place of CFC propellants, dimethyl-ether is gainly a foothood in the domain of emerging transportation fuels, in part because it shares some useful similarities with liquid petroleum gas (LPG) and natural gas (NG).


Properties

Gas, non-toxic


Production

DME is derived from the methanol produced during the chemical conversion of coal, natural gas, or biomass.


CO₂ Emissions

ZERO NET


Fuel Blends

Yes
DME can be blended with LPG


Infrastructure

In Place
Conceivably, DME could use the entire existing infrastructure for propane.


Advantages

• Its high cetane number makes it likely suited for deisel engines.
• As a fuel source, DME has the potential to meet a broad range of energy needs, at power plants, within the home, and in diesel engines, to name a few.


The Future …

… of DME is difficult to guage free of bias at this extremely early time, but there is some potential for using DME as a hydrogen source for fuel cells.
