CNG FinderPublic CNG stations, mapped

Who runs America's CNG stations

Roughly 71% of public CNG stations belong to a named network, and the top six (Clean Energy, Chevron, Love's, Kwik Trip, Oklahoma Natural Gas, Enbridge) account for 319 of 674. Network matters because it decides which card works, whether a Class 8 truck fits, and whether the fuel is renewable.

Networks are inferred from the station name in the DOE record, so a station branded by a utility but run by a contractor is counted under the utility. Independent sites include city fleet stations that sell to the public, small operators and single-site retailers.

Reading the network table

Clean Energy is the largest operator in the country by a wide margin, with truck-oriented stations in most states that have any natural gas trucking, and RNG (sold under its Redeem brand) at nearly all of them. Chevron entered the business in 2023 by buying Beyond6, whose stations kept their locations and mostly their layouts. Kwik Trip and its fuel arm U.S. Gain run the Upper Midwest, where filling means pulling into a convenience store. Trillium is a Love's subsidiary that builds and runs stations for transit agencies and along the turnpikes; Love's itself has dispensers at a run of travel stops, most of them in Oklahoma and Texas. Oklahoma Natural Gas, Enbridge (the former Questar in Utah and PSNC in North Carolina), PG&E, Piedmont and SoCalGas are utilities that built public stations at their own facilities.

The "independent / other" row is the long tail: cities, transit agencies, school districts and county fleets that sell fuel from their yards, plus single-site operators and small regional chains. They are often the only fill in a rural county, and they are also the sites most likely to have office hours, a card key, or a canopy a trailer cannot clear, so the badges matter more there than anywhere.

Two practical points. Card acceptance follows the network: Clean Energy takes its own card plus most fleet cards, Kwik Trip takes anything a gas station takes, and utility sites vary. And "Class 8 OK" is a data field, not a promise: a Kwik Trip store marked for heavy-duty may still be a tight lot for a 53-foot trailer, while a Clean Energy truck station was built for one.
