The Bioenergy Technologies Office of the U.S. Department of Energy Office of Energy
Efficiency and Renewable Energy sponsored a scoping study to assess the potential of ethanolbased
high octane fuel (HOF) to reduce energy consumption and greenhouse gas emissions.
HOF blends used in an engine designed for higher octane have the potential to increase vehicle
energy efficiency through improved knock suppression. When the high-octane blend is made
with 25%–40% ethanol by volume, this energy efficiency improvement is potentially sufficient

The U.S. Department of Energy (DOE) is supporting engine and vehicle research to investigate the potential of high-octane fuels to improve fuel economy. Ethanol has very high research octane number (RON) and heat of vaporization (HoV), properties that make it an excellent spark ignition engine fuel. The prospects of increasing both the ethanol content and the octane number of the gasoline pool has the potential to enable improved fuel economy in future vehicles with downsized, downsped engines.

Share and discuss provisional findings from coordinated DOE national laboratory studies on the opportunities and challenges associated with the deployment of high octane, mid-level ethanol blend transportation fuels.

This project looks at the potential of blending ethanol with natural gasoline to produce Flex-Fuels (ASTM D5798-13a) and high-octane, mid-level ethanol blends. Eight natural gasoline samples were collected from pipeline companies or ethanol producers around the United States.
