City of Dallas, Texas Begins Fleet B20 Biodiesel Use

5 April 2007

The City of Dallas, Texas is fueling several hundred vehicles—including sanitation trucks, utility trucks and construction equipment—with a B20 biodiesel blend combined with a NO_x-reducing additive from Oryxe Energy.

The Texas Commission on Environmental Quality (TCEQ) recently approved the use of Oryxe LED for Biodiesel after test results sowed that the additive reduces the increase in NOx (oxides of nitrogen) emissions from biodiesel to the level required to qualify as Texas Low Emission Diesel (TxLED). (Earlier post.)

Based on testing data from the Environmental Protection Agency (EPA), the state of Texas has determined that a straight B20 biodiesel blend exceeds the NO_x levels required by TxLED. Use of biodiesel thus requires an approved additive to lower NO_x emissions. The Oryxe Energy technology is the first additive for biodiesel to win approval from the state of Texas.

The City of Dallas is constantly striving to be at the forefront of clean technology, and we hope our example will lead to other large diesel fleets using this cleaner fuel blend. With NO_x being such a big issue in the Metroplex, we waited for this technology to become available so we could reintroduce biodiesel into our fleet.
