CNG Station Map: The Definitive Guide to US Natural Gas Fueling Infrastructure
The official CNG station map is available through the U.S. Department of Energy's Alternative Fuels Data Center (AFDC), which displays all 1,385 operational compressed natural gas fueling stations across 47 states plus Washington, D.C. as of December 2025. California leads with 318 stations, followed by Oklahoma, Texas, Pennsylvania, and Florida, revealing significant infrastructure gaps in the Midwest and Southeast where station density remains below national averages.
Where to Access the Official CNG Station Map
Fleet operators and individual drivers can access three primary station locator tools for real-time CNG station information:
- DOE Alternative Fuels Data Center: The official government map at afdc.energy.gov/stations provides filters for public/private access, heavy-duty capability, and RNG dispensing
- The Transport Project NGV Station Map: Interactive map with advanced filters for RNG fueling and vehicle accessibility, covering U.S. and Canada
- CNG Fuel Finder App: Mobile application offering GPS navigation, pressure checks, pricing, and user-submitted station photos
US CNG Infrastructure by State: Key Data Points
The Q4 2025 NGV Refueling Infrastructure Report reveals critical regional disparities in natural gas fueling access that directly impact fleet deployment decisions:
| State | CNG Stations | % of National Total | Public Access |
|---|---|---|---|
| California | 318 | 23.0% | 58% |
| Oklahoma | 99 | 7.1% | 62% |
| Texas | 95 | 6.9% | 55% |
| Pennsylvania | 72 | 5.2% | 49% |
| Florida | 59 | 4.3% | 61% |
| Georgia | 49 | 3.5% | 47% |
| Wisconsin | 44 | 3.2% | 52% |
| New York | 44 | 3.2% | 48% |
| Ohio | 43 | 3.1% | 50% |
| Utah | 40 | 2.9% | 54% |
These top 10 states account for 57.4% of all US CNG infrastructure, leaving 37 states with fewer than 40 stations each.
Infrastructure Gaps That Matter for Fleet Operators
The shocking infrastructure gaps referenced in industry analysis stem from three critical factors affecting operational feasibility:
- Public Access Limitations: Only 53% of the 1,385 CNG stations are publicly accessible, meaning nearly half require fleet membership or private authorization
- Heavy-Duty Capability: Just 46% of stations offer Class 8 truck access, creating corridor gaps for long-haul trucking operations
- Geographic Concentration: Operational stations exist in only 47 states, with Montana, Wyoming, and North Dakota having fewer than 5 stations each
For LNG specifically, only 81 stations exist nationwide, concentrated primarily along major freight corridors serving the long-haul trucking industry.
CNG Station Types and Technical Specifications
Understanding station configuration is essential for fleet planning, as three distinct types serve different operational needs:
Fast-Fill CNG Stations
Fast-fill stations compress gas from utility lines to 3,600 psi using on-site compressors, then store CNG in adjacent tanks for quick refueling equivalent to conventional gasoline/diesel pumps. All public CNG stations offer fast-fill capability, making them ideal for retail and random-arrival scenarios.
Time-Fill CNG Stations
Time-fill stations deliver fuel directly from utility compressors without storage vessels, requiring vehicles to fill over several minutes to hours. These behind-the-fence operations serve refuse trucks, school buses, and fleets with centralized overnight refueling. Installation costs are significantly lower due to eliminated storage requirements.
LNG Fueling Stations
LNG stations receive cryogenic fuel via specialized tanker trucks, storing it at -260°F before dispensing at 30-120 psi. Personnel require protective equipment and specialized training due to cryogenic handling risks.
Installation Costs and Economic Considerations
Infrastructure investment decisions require precise cost modeling based on station type and capacity:
- Small CNG units: Average $10,000 including engineering, equipment, and installation
- Full-scale CNG stations: Range up to $1.8 million depending on size, application, and compressor capacity
- LNG stations: Range from $1 million to several million, driven by storage capacity and cryogenic containment requirements
Local utility consultation is critical before installation, as gas pressure, quality, moisture content, and flow capacity must support operational demands.
RNG and Decarbonization: The Carbon-Negative Advantage
51% of CNG stations nationwide directly dispense renewable natural gas (RNG), enabling fleets to achieve ultra-low-carbon operations. California's LCFS program reports bio-CNG mix at -218.89 gCO₂e/MJ, allowing carbon-negative transportation outcomes for fleets fueling in the Golden State.
In 2024, 86% of all natural gas motor fuel dispensed for transportation use in the United States was RNG, demonstrating rapid decarbonization momentum within the gaseous fuel sector.
Strategic Implications for LNG Market Participants
The two percent year-over-year increase in CNG stations indicates modest infrastructure growth, but the concentration in top-10 states creates competitive advantages for fleets operating in California, Oklahoma, and Texas. Investors and procurement teams should note that RNG dispensing capability now exists at majority of stations, positioning natural gas as a transitional fuel within the broader global LNG value chain.
For executives evaluating fleet decarbonization strategies, the CNG station map reveals both opportunity and constraint: sufficient infrastructure exists in key markets for immediate deployment, while geographic gaps necessitate route planning or private infrastructure investment for national coverage.
Helpful tips and tricks for Why Your Cng Station Map Shows Fleet Routes Hitting Dead Ends
How do I find the nearest CNG station?
Use the DOE Alternative Fuels Data Center Station Locator at afdc.energy.gov/stations, enter your city/state or address, select "Natural Gas (CNG/LNG)" as fuel type, and apply filters for public access or heavy-duty capability.
How many CNG stations are open to the public?
Of the 1,385 operational CNG stations in the US as of December 2025, 53% (approximately 734 stations) are publicly accessible.
Does the CNG station map include LNG stations?
Yes, both the DOE AFDC locator and The Transport Project NGV Station Map display all 81 LNG stations alongside CNG stations with separate filtering options.
What states have the fewest CNG stations?
Montana, Wyoming, and North Dakota each have fewer than 5 CNG stations, representing the most significant infrastructure gaps in the national network.
Can I use CNG stations for heavy-duty trucks?
Only 46% of CNG stations offer Class 8 heavy-duty truck access; use the "Heavy-Duty" filter in the station locator to identify compatible facilities.
