as the dispenser, shear valve, breakaway, nozzle, swivel, hose and

As part of the DOE’s E15 test program, NREL contracted
with UL to test used dispensers and hanging hardware with 17
percent ethanol blended with a gasoline surrogate test ;uid.
Unfortunately, the test is rigorous for new equipment, and some
of the used equipment leaked. Nevertheless, this provided useful information: Elastomer degradation caused all the leaks.
The discovery led to collaboration with industry groups and
refueling manufacturers to understand the results and what was
necessary to ensure safety, performance and legal sales of the
NREL worked with dispenser manufacturers to test and
obtain UL certi;cation for retro;t kits that would have allowed
existing dispensers to be upgraded to accommodate E15. In the
intervening years, stations that sold E15 and E85 replaced existing equipment with E85 dispenser blender pumps. NREL also
worked with refueling manufacturers and the National Biodiesel
Board to obtain UL certi;cation for B20 equipment. NREL
asked manufacturers directly to send samples for UL testing.

Renewable fuels such as ethanol and biodiesel
typically ship by truck or rail from production facilities
to transmodal facilities or terminals.
Terminals store renewable fuels, diesel, blendstock
for oxygenate blending and additives separately. The
final fuel formulations are delivered to trucks at the
terminals for final delivery to end users, most often
Pipelines rarely carry renewable fuels for several
reasons: production locations, pipeline flow direction,
volumes and potential contamination of jet fuel.
But the same trucks, rail cars and barges that carry
gasoline and diesel also carry ethanol and biodiesel.
At the terminals, only minimal differences exist
between the equipment used for renewable and
petroleum fuels. These midstream activities require
deeply trained staff for handling and maintaining
