CO2 Emissions

ZERO NET

Fuel Blends

DME can be blended with LPG

Infrastructure

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

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