Oberon DME Receives EPA's First Biogas-Based Fuel Approval Under the Renewable Fuel Standard

The transportation industry, particularly the heavy-duty sector, now has another option under the RFS for a domestically produced, renewable fuel.

SAN DIEGO, Sept. 3, 2014 -- Oberon Fuels Inc.

("Oberon"), the first company to announce plans to commercialize
biogas-based dimethyl ether ("DME") fuel production in North America,
announced today that the United States Environmental Protection Agency
("EPA") has approved its DME for inclusion under the Renewable Fuel Standard
("RFS"). Oberon's biogas-based DME is now eligible for high value D-Code 3
(cellulosic) and D-Code 5 (advanced) renewable identification numbers
("RINs") under the RFS. 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.

"Less than a year after submitting our pathway petition, this biogas
produced fuel was approved. We are excited to see the EPA continue to
support innovative, new fuels and include Oberon's DME under the Renewable
Fuel Standard," said Rebecca Boudreaux, Ph.D., president of Oberon Fuels.

"One of the exciting attributes of DME is that, at its core, DME is a simple
fuel," according to Oberon's co-founder and COO Elliot Hicks.
"It requires a simple diesel engine and has simple propane-like handling
properties."

The transportation industry, particularly the heavy-duty sector, now has
another option under the RFS for a domestically produced, renewable fuel.
"Our customers are engaged in heavy-duty applications and need the power and
torque of a diesel engine," said Susan Alt, Volvo Group North America's
senior vice president of public affairs. "Oberon's DME offers that power
without the need for the cryogenics or high compression associated with
other diesel alternatives. We look forward to continuing our work with
Oberon to demonstrate the benefits of this clean-burning, non-toxic diesel
alternative for the heavy truck industry."

The EPA's approval of biogas-based DME is the latest milestone for the
growing DME industry. In February 2014, ASTM International, a globally
recognized organization that develops technical standards, released a
specification for DME as a fuel. ASTM D7901 provides guidance for fuel
producers, engine and component suppliers, and infrastructure developers on
DME purity, testing, safety, and handling.

About Oberon Fuels

California-based Oberon Fuels monetizes biogas and other hydrocarbon rich
waste streams by converting such feedstock into higher valued commodities.
Using its proprietary small-scale process, Oberon makes DME, a clean-burning
diesel alternative, and methanol from methane and carbon dioxide. In 2013,
Oberon Fuels' pilot plant in Brawley, California produced the first
fuel-grade DME in North America, which is currently being used by Volvo
Trucks, a division of The Volvo Group, in its commercial demonstrations of
DME-powered, heavy-duty trucks. To learn more about Oberon Fuels, visit
