About the research

In an effort gain a greater understanding of the impacts of alternative blends of ethanol-based fuels (E30 in particular), the Iowa Department of Agriculture and Land Stewardship (IDALS) and the Iowa Department of Transportation (DOT) have initiated a pilot project that builds upon the IDALS existing Renewable Fuels Infrastructure Program.

This pilot project provides funding as an incentive to private sector installation of renewable fueling pumps (likely blender pumps) and also includes a research and analysis component to assess the impacts of installation of these pumps on consumer behavior and emissions. The Fueling our Future pilot program is administered by the Iowa Renewable Fuel Infrastructure Program (RFIP) of IDALS and the Iowa DOT.

This program seeks to gain better consumer information about fueling preferences, focus on marketing opportunities that will increase the use of higher blends of ethanol and biodiesel, and provide a pathway to reduce particulate matter (PM 2.5 or less) in Iowa.

The project utilizes grant incentives to encourage interest and participation for specific infrastructure upgrades and data sharing. The data sharing is expected to involve sharing of fuel sales over a specified time period and limited access to customers and employees to gather information and data. The extent of this data sharing will be mutually agreed upon by all parties.

Two sites were selected:

  • The Farmer’s Cooperative station in Mount Ayr will offer ElO, E15, and E30, ESO and E85 and BS, B 10, and B20. Mount Ayr is in Ringgold County.
  • Oak Street Station is in Inwood, Iowa (Lyon County). The station will offer ElO, E15, E30, and E85. B-5 will be offered year-round with B99.9 offered during the summer months for independent jobbers and special use customers such as tractor pullers (http: //domesticfuel.com/2014/04/14/iowa-gov-branstad-expands-fueling-our-future/d).

The Center for Transportation Research and Education (CTRE) at the Institute for Transportation (InTrans) at Iowa State will conduct an analysis of the project to determine user acceptance of the program and assess air quality impacts of several different implementation scenarios. This will entail collecting data from the two sites to determining the number of users of different blends as well as collecting on-site data to survey users.
