Oberon Fuels’ DME has been evaluated and approved for use as a low-carbon transportation fuel by a variety of federal and state agencies.
ASTM International has developed technical specifications for fuel-grade DME. Initially published in 2014, ASTM D7901 provides guidance for fuel producers, engine and component suppliers, and infrastructure developers on DME purity, testing, safety, and handling. The International Organization for Standardization (ISO) has specified DME characteristics for use as fuel in ISO 16861:2015 . Recently, ISO developed a new working group ISO/TC22/SC41/WG8 which is focusing on developing standards for DME fuel systems.Environmental Protection Agency
The U.S Environmental Protection Agency has approved a Renewable Fuel Standard (RFS) pathway for DME production from biogas with the Oberon process. The approval makes DME eligible for D3 cellulosic and D5 advanced biofuel renewable identification numbers (RINs) under the RFS.State of California
With the modification of California Code on January 1, 2015, DME has been approved for sale in the state of California by the California Department of Food and Agriculture (CDFA). In addition, the California Air Resources Board (CARB) published their Tier 1 Report in 2014 on DME as part of their Multimedia Evaluation process for new fuels. With these actions in California, and since the EPA does not require DME to be registered under Part 79, DME can now be used as a fuel in all 50 states across the US.
DME offers performance that is similar to diesel but burns cleaner, making DME an ideal fuel for fleets that have to haul heavy loads. DME produces zero soot, zero sulfur oxides (SOX), less NOX levels and also significantly reduces greenhouse gas emissions.
