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.

Australia CSIRO and India CSIR launch A$6M partnership on dimethyl ether

October 10, 2013

Australia’s CSIRO and its equivalent in India, the Council of Scientific and Industrial Research (CSIR), have launched a three-year, A$6-million (US$5.6-million) collaboration focused on improving processes involved in the production of dimethyl ether (DME), a clean-burning synthetic liquid fuel.

DME is non-toxic and non-carcinogenic and can be produced from natural gas (NG), coal, biomass, or even directly from carbon dioxide. It offers diesel-quality performance with a high cetane number and low auto-ignition temperature, but burns cleanly without producing any soot. The carbon intensity of the DME will vary with the feedstock.
