(UNDATED) - Indiana’s Department of Transportation is studying how much of its future is in compressed natural gas.
INDOT bought 19 compressed natural-gas powered dump trucks at the end of 2012. The department uses them to haul equipment and salt.
Spokesman Nathan Riggs says there's a projected savings of 36,000 dollars a year. But even if the trucks meet that projection, there are limits to how far INDOT can expand the program.
Riggs says there are only a handful of CNG refueling stations in the state, most of them in the Indianapolis area.
Indiana enacted a law last year creating tax incentives for buying CNG-powered trucks, in hopes of creating demand for more stations. Riggs says it's too soon to say how well that effort is working.
INDOT is also experimenting with propane-powered trucks.
