NREL Report Confirms IRFA’s Real World Testing Data

JOHNSTON, IOWA –The Renewable Fuels Association (RFA) today released a report by the National Renewable Energy Laboratory (NREL) that confirms real world E15 test data released by the Iowa Renewable Fuels Association (IRFA) last week.

NREL’s report found that the available literature on E15, a 15 percent ethanol blend, “…did not show meaningful differences between E15 and E10 in any performance category.” It also noted that with respect to the Coordinating Research Council’s (CRC) controversial engine durability study, NREL found “…the conclusion that engines will experience mechanical engine failure when operating on E15 is not supported by the data.”

Last week, the IRFA released its own testing data from vehicles driving in the real world that demonstrates Big Oil’s earlier CRC testing on E15 has no real world implications.  To highlight the point, IRFA staff drove a vehicle that exceeded Big Oil’s arbitrary testing threshold for cylinder leakdown from Iowa to Washington, D.C.  Members of Congress, staff and media were invited to test drive the vehicle during an event on Capitol Hill.

“The NREL report is the final nail in the coffin for Big Oil’s bogus E15 studies,” stated IRFA Executive Director Monte Shaw. “Big Oil has consistently pointed to two CRC studies as a basis to outrageously claim that E15 will cause engine damage and leave motorists in harm’s way. IRFA’s real world testing data combined with today’s NREL analysis proves Big Oil’s irresponsible statements on E15 cannot be trusted.”

Iowa is the leader in renewable fuels production. Iowa has 41 ethanol refineries capable of producing over 3.7 billion gallons annually, with one wet mill and three cellulosic ethanol projects currently under construction. In addition, Iowa has 12 biodiesel facilities with the capacity to produce nearly 315 million gallons annually.

The Iowa Renewable Fuels Association was formed in 2002 to represent the state’s liquid renewable fuels industry. The trade group fosters the development and growth of the renewable fuels industry in Iowa through education, promotion, legislation and infrastructure development.
