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.
