Clean Energy Fuels Corp. (NASDAQ: CLNE) announced the opening of six new renewable natural gas stations positioned along major freight transportation routes in the United States. The company made the announcement at the Advanced Clean Transportation Expo.

The new stations are located in California, New Jersey, Oklahoma, Michigan and Washington. Clean Energy operates a network of over 600 fueling locations across North America serving transit, refuse, municipality, airport operations, and trucking fleets.

The six stations include locations in Bordentown, New Jersey; Tracy and West Sacramento, California; Woodhaven, Michigan; Oklahoma City, Oklahoma; and Pacific, Washington. All stations are positioned near distribution centers and provide access to major freight corridors.

"With diesel prices remaining very high and volatile, it's perfect timing to expand our offering of a price-stable, low-cost fuel for fleets who want to cut their carbon emissions, but do it affordably," said Chad Lindholm, senior vice president at Clean Energy.

The stations support the use of Cummins' X15N 15-liter natural gas engine for long-haul and heavy-duty fleets. Each station is equipped with multiple fast-fill fueling dispensers and is accessible to tractors pulling trailers.

Clean Energy describes renewable natural gas as a sustainable fuel derived by capturing methane from organic waste. The company operates RNG production facilities at dairy farms in addition to its fueling station network.
