California approves sale of DME as compression-ignition engine fuel
February 27, 2015
The California Department of Food and Agriculture has approved specifications for dimethyl ether (DME) used as fuel in compression ignition engines. (The Department of Food and Agriculture Division of Measurement Standards has the responsibility for establishing and enforcing the quality standards for spark- and compression-ignition engine fuels sold in California. These include gasoline, diesel fuel, and other fuels such as biodiesel and hydrogen.)
This latest approval builds on earlier approvals and ongoing work by other regulatory bodies, including the US Environmental Protection Agency, the California Air Resources Board, and ASTM International, and will help accelerate commercial adoption of this low carbon fuel, commented Oberon Fuels, a California-based company that is the first to produce fuel-grade DME in North America.

Oberon’s biogas-based DME now eligible for D3 and D5 RINs under the RFS
September 03, 2014
Oberon Fuels Inc., the first company to announce plans to commercialize biogas-based dimethyl ether (DME) fuel production in North America (earlier post), announced that the US Environmental Protection Agency (EPA) has approved Oberon’s biogas-based DME for inclusion under the Renewable Fuel Standard (RFS).
Oberon’s biogas-based DME is now eligible for high-value D3 (cellulosic) and D5 (advanced) renewable identification numbers (RINs) under the RFS. (Earlier post.) The EPA determined that biogas-based DME produced from the Oberon process resulted in an approximate 68% reduction in greenhouse gases when compared to baseline diesel fuel.

Europe’s Joint Research Centre (JRC) and its partners in the JEC Consortium—JRC, EUCAR (the European Council for Automotive R&D) and CONCAWE (the oil companies European association for environment, health and safety in refining and distribution)—have published a new version of the Well-to-Wheels Analysis of Future Automotive Fuels and Powertrains in the European Context. (Earlier post.)
The updated version includes a longer-term outlook by expanding the time horizon from 2010 and beyond to 2020 and beyond. It adds an assessment of electrically chargeable vehicle configurations, such as plug-in hybrid, range extended, battery and fuel-cell electric vehicles. It also introduces an update of natural gas pathways, taking into account the addition of a European shale gas pathway. Furthermore, biofuel pathways, including an entirely new approach to NOx emissions from farming, were thoroughly revised.
