Dimethyl ether (DME) holds much promise as a heavy-truck fuel, and could become a viable alternative in North America to compressed or liquefied natural gas when it comes to performance, environmental impact, safety and distribution. DME is a colorless, odorless, and tasteless compound that can be made from a variety of sustainable domestic sources, as well as from North America’s abundant supply of natural gas. DME mirrors the exceptional performance qualities and energy efficiency of diesel, and burns clean without producing any soot so no diesel particulate filter is required.
It is non-toxic, non-carcinogenic, degrades rapidly in the atmosphere and is not a global warming agent. DME behaves similar to propane, so it’s stored and transported at ambient temperatures in tanks similar to those used in the propane industry.
