Sometimes adding one thing can help take something else
That's the simplest way of explaining the strategy behind a
new biodiesel additive coming to market in East Texas.
Texas Commission on Environmental Quality demands that all
fuel, including biodiesel, meet the strict standards of the Texas Low Emission
Diesel program, also referred to as the TxLED program. The commission recently
approved a product called Oryxe LED, the first-ever biodiesel additive to be
approved for use in Texas by fuel producers to reduce nitrogen oxide emissions,
also known as NOx.
Produced by the California company Oryxe Energy
International, the product can be added to biodiesel blends up to B20 - which
is 80 percent petroleum diesel blended with 20 percent biodiesel.
The Oryxe additive satisfies TxLED requirements, which are
similar to standards set by the California Air Resources Board, according to a
Texas environmental commission spokesman.
"Those rules are designed for producers and importers of
fuel into the 110-county region," Morris Brown, air-quality technical
specialist for the Texas Commission of Environmental Quality, told Land Line.
Brown said there are four ways fuel producers can meet TxLED
standards of 10 percent maximum aeromatics and a minimum cetane number of 48.
of an approved alternative fuel formulation including additives;
import and use of a certified "California diesel" fuel;
of an approved diesel formulation produced locally; or
implementation of a government-approved emission-reduction strategy.
Brown said the biodiesel additive by Oryxe is an example of
the first option on the list.
"At this point, there is only one alternative formulation
approved by (the environmental commission) for biodiesel, and that's Oryxe
additive," he said. "We're hoping other biodiesel producers and blenders will
come through and go through the provisions to be approved as alternative
As part of an ongoing discussion about whether pure,
unblended biodiesel already meets standards for NOx emissions, the Texas
Commission on Environmental Quality is scheduled to meet May 9.
On the agenda that day is a proposed vote to extend the
deadline to Dec. 31 for biodiesel producers to either show science to back up
their claim about emissions, or begin complying. The old deadline of Dec. 31,
2006, has already passed, but the state has opted not to enforce penalties
during the debate.
