A new iPhone app by the National Renewable Energy Laboratory (NREL) allows users to locate fueling stations offering alternative fuels, including electricity, natural gas, biodiesel, E85, propane, and hydrogen, nation-wide.

Available for download through Apple's App Store, the Alternative Fueling Station Locator app allows iPhone users to select which type of alternative fuel they need to power their green vehicle and find the 20 closest stations within a 30-mile radius. The app also provides the station addresses, phone numbers, and hours of operation.

"Generally, people don't search for a station while they're sitting at a computer; they need this information while they're out and about, which makes a mobile application the ideal means to deliver it," said NREL Project Manager Trish Cozart.

The app pulls data from Clean Cities' Alternative Fuels Data Center, a comprehensive, up-to-date database of alternative fueling stations in the United States. The database contains location and contact information for more than 15,000 alternative fueling stations throughout the country.
