It’s Good News for Oberon Fuels, and for Volvo-Mack
ASTM D7901 Standard for DME
February 9, 2014 in Alternative Fuels, Biofuels, DME, Publications by Rich Piellisch | No Comments
ASTM International has issued a standard for dimethyl ether, a diesel replacement that can be made from organic material.
Volvo Trucks is an early backer of DME as a clean alternative to diesel.
ASTM D7901 for DME, the organization says, “is for use by manufacturers of dimethyl ether, by engine developers of purpose-built engines, in contracts for the purchase of DME for fuel purposes, and for the guidance of consumers of this type of fuel.”
Firms including Oberon Fuels in California and Volvo Trucks (and its affiliate Mack) see significant advantages over more prevalent alternatives (F&F, June 11, 2013).
Low Pressure Tanks
DME can be made from methane-derived landfill gas, sewage or organic waste via a process said to be economical in part because there is no need, as with biomethane production, to remove carbon dioxide.
Like propane autogas, DME can be stored in low-pressure, ambient-temperature tanks – another advantage over CNG or LNG. The new ASTM standard, in fact, covers DME-propane blends.
