Get up to speed on DME's introduction as a fuel directly from those most involved with the strategic and technical aspects of its commercialization in North America and elsewhere - recent features include insights from a heavy-duty diesel engine OEM, refiner, technology provider, and well-known R&D center.


DME Receives Approval for Legal Use as a Vehicle Fuel in California

The State of California has approved DME’s use as a vehicle fuel, allowing the retail sale of DME throughout the state. The regulation, Specifications for Dimethyl Ether Used in Compression Ignition Engines, represents another significant milestone that will help accelerate commercial adoption of DME in North America.


What the Developing DME Market Means for LPG

A new Strategic Partnership agreement with the Propane Education & Research Council (PERC) and involvement by industry representatives in DME initiatives all reflect the growing interest by propane distributors, equipment and infrastructure manufacturers and project developers in the opportunities presented to the propane industry globally by the introduction of DME as a fuel.


DME Becomes First Biogas-Based Fuel Approved Under Renewable Fuel Standard

The U.S. Environmental Protection Agency ("EPA") has confirmed that DME produced from biogas and other renewable sources using the Oberon Fuels' process qualifies for inclusion under the Renewable Fuel Standard, making the fuel eligible for high value RINS credits under the Clean Air Act.


ASTM Issues Specification for DME Fuel

ASTM International has issued a standard specification for DME for fuel purposes, providing DME producers, engine manufacturers, infrastructure developers and others involved in the introduction of DME as a fuel with an important benchmark on which to base their work.



DME for Fleets
Growing interest by fleet owners and OEMs in the use of DME as a transport fuel reflects DME's promise as a low carbon, ultra-low emissions alternative to diesel.  Produced from abundant and low cost feedstocks such as natural gas, coal, and biomass, few modifications are required to a diesel engine in order to use DME.

DME Fuel plant at MGC facility, Niigata, Japan
Commitment Reaffirmed for US$850 million 
methanol-to-DME project in Trinidad and Tobago 

The government of Trinidad and Tobago, Japan's Mitsubishi Corporation and Mitsubishi Gas Chemical Company, and local group Neal and Massy reaffirmed their commitment to develop an US$850 million methanol-to-DME plant there. The first phase of the project involves the production of 1 million TPY of methanol and 100,000 TPY of DME. 

Japan's first DME production plant (pictured above) is located in Mitsubishi Gas Chemical's industrial facility in Niigata.  The Fuel DME Production Company plant is a joint venture of a number of Japanese companies including Mitsubishi Gas Chemical, Mitsubishi Heavy Industries, and Mitsubishi Chemical Company, and has a capacity of 80,000 TPY of DME.

Volvo Trucks and DME - The Basics

Watch video below to learn more about Volvo's pioneering decision to commercialize DME-powered heavy-duty trucks in North America



Mack Trucks Announces DME-Powered Truck Model

Mack Trucks will begin production of DME-powered Mack Pinnacle Axle Back models. The model powered by DME will be equipped with a Mack MP8 engine, offering a 13-liter engine to easily handle heavy workloads.

“The benefits of DME are numerous,” said Kevin Flaherty, president of Mack Trucks North American Sales & Marketing. “It’s better for the environment because it burns clean, and it can be made from sources that are domestically available. Mack trucks are built in the U.S.A., and with DME, we’ll be powering our vehicles with a fuel made in America as well.”

“DME is unique in that it is clean, easy to handle, safe to store and will be made domestically, benefiting everyone.” DME can be produced by small-scale production units that convert biogas and natural gas into the fuel. Oberon Fuels' first innovative production unit is in operation in California’s Imperial Valley region.


Volvo Trucks to Commercialize DME-Powered Vehicles for North America

Volvo Trucks became the first manufacturer to announce plans to commercialize DME-powered heavy-duty commercial vehicles in North America. As the latest step in its comprehensive “Blue Power” alternative fuel strategy, Volvo revealed ongoing U.S. customer field testing of trucks powered by DME, and demonstrated the technology after an announcement at the California State Capitol.

DME mirrors the exceptional performance qualities and energy efficiency of diesel, and burns clean without producing any soot. Converting natural gas to DME is an innovative way to address many of the distribution, storage and fueling challenges otherwise presented by natural gas as a heavy truck fuel.

“With the addition of DME-powered vehicles to our previously announced CNG and LNG offering, Volvo’s Blue Power line-up will offer the industry’s most comprehensive approach to the developing North American alternative fuel market,” said Göran Nyberg, president of Volvo Trucks North American Sales and Marketing.
