Alternative Fuels Research

Research in this area evaluates the feasibility of running vehicles on non-petroleum fuels, such as alcohol fuels. The use of alternative fuels can potentially lower health-related emissions, reduce greenhouse gas emissions, and create less dependence on imported oil.

EPA's advanced research in alternative transportation fuels, such as ethanol and methanol, explores their potential for providing a cost-effective means of using sustainable fuels to achieve both low emissions and high fuel economy. Alternative fuel research consists of engine and vehicle development to achieve an economical alternative to conventional gasoline and diesel engines.

• Presentation: Ethanol-Gasoline Blends: Fuel Economy and Emissions Benefits (PDF) (13 pp, 107K) (delivered May 13, 2003, at the SAE Government and Industry Meeting). This presentation describes recent work at EPA with ethanol-gasoline blends, highlighting the potential cost and emissions benefits of E30.
  
• Presentation: Research in Alcohol-Fueled Engines at EPA NVFEL (PDF) (12 pp, 167K) (delivered February 25, 2003, at the NEVC Annual Meeting). This presentation describes recent work at EPA with pure ethanol and methanol fuels, including the context of EPA NVFEL's work - the results and the challenges. The results show the ability to achieve diesel-like efficiency with low steady-state emissions on the level of Tier 2.
