MORE ON THE BLEND "WALL"

HEATHER YOUNGS – EBI UC BERKELEY WHY IS THE BLEND FENCE IMPORTANT?

• Blending can reduce GHG emissions immediately • Cellulosic ethanol is here – high value RINs will follow • Ethanol is political and so is the blend "wall" • Creating an artificial limit on ethanol blending has economic impacts E15 AND ARE IMPORTANT TOOLS IN REACHING THE LCFS 2020 GOAL

• 2001 and newer and flex- vehicles (75% of cars, trucks and SUVs on the road meet EPA criteria) • 45% of new vehicles are warranteed for E15 >70% of the Top 20 best-selling cars 2014 models. All Ford, GM and Volkswagen 2014 models Some Honda, Toyota, Mercedes-Benz, Jaguar and Land Rover.

• reduced fuel economy due to the lower energy density of ethanol • increased emissions of pollutants such as nitrogen oxides (NOx) due to higher catalyst temperatures • corrosion of metals and other materials in engines and fuel systems • degradation of elastomers, polymers, and seals, which can lead to fuel leaks • phase separation of water and ethanol from . REGARDING EMISSIONS

• If the ratio of air to fuel is not adjusted when using ethanol blends, fuel may not completely combust and exhaust temp may rise affecting the catalytic converter, increasing some emissions. • Modern cars have the ability to prevent this imbalance by automatically adjusting the air/fuel ratio depending on the ethanol content of the fuel. • Older vehicles, however, as well as many motorcycles, lawnmowers, and other off-road equipment, do not.

• Tailpipe emissions were similar; • Under normal operations, catalyst temperatures in the 13 cars were largely unchanged; • When tested under full-throttle conditions, about half of the cars exhibited slightly increased catalyst temperatures with E15 and E20, compared to traditional gasoline; and, • Based on informal observations during testing, drivability was unchanged.

NREL, ORNL Testing 2007 SMALL ENGINES (E15 AND E20)

• As ethanol content increased: • Regulated emissions generally stayed within allowed limits, • and exhaust temperatures increased; • Commercial engines, as well as larger non-handheld residential engines in this limited study, exhibited no particular sensitivity to ethanol from a durability perspective; and, • The effect of E15 and E20 on the durability of smaller, less- expensive handheld residential engines was not clear. FLEX FUEL VEHICLE OWNERSHIP UP

• Iowa, sales of fuel to flex-fuel vehicle owners jumped 43 percent in the second quarter of 2013 • 15 million flex-fuel vehicles on the road, constituting about 6 percent of the entire vehicle fleet, • A survey by the National Association of Convenience Stores in June found that consumers were largely still unaware of E85: Only 29 percent of 1,183 consumers surveyed were familiar with E85, while only 10 percent said they drove a flex-fuel vehicle (Greenwire, June 12). • Babcock and Pouliot found that only a third of flex-fuel vehicle owners have access to an E85 station within 5 miles of their home. CAFE STANDARDS ARE KEY DESPITE LOWER PRICES, ADVERTISING AFFECTS CHOICES E15 is typically discounted 10-15 ¢/gallon At this station E10 was priced 60 ¢/gallon lower (3.65 ¢/MJ ethanol free, 3.22 ¢/MJ E10)

• Ethanol blends can help mitigate climate change • There are no technical barriers to higher ethanol blends • Physical infrastructure can be adapted to higher ethanol blends in a short time period • Political barriers to higher ethanol blends can be overcome • Pricing of fuels on energy content will be needed • CAFE standards should be adjusted • Warranties and certifications need to be aligned • Misinformation must be countered • We will see even more fuel options in the future
