From delivery and utility fleets to light- and heavy-duty vehicles, public transit buses, waste collection trucks, taxis, and rideshare vehicles, natural gas vehicles (NGVs) — which run on CNG — are becoming a common sight on U.S. roadways. CNG is one form of natural gas used to power NGVs — the other is liquefied natural gas (LNG). For purposes here, we’ll focus on CNG and why so many fleets are exploring it as an alternative fuel. ### **What Is Compressed Natural Gas, and How Does It Work?** CNG is a fuel made primarily of methane, the same natural gas used for heating homes and powering businesses. It’s domestically produced, widely available, and classified as an [alternative fuel](https://blog.psenergy.com/sustainability-starts-with-alternative-fuels). Unlike liquid fuels, CNG is stored as a gas under high pressure. It is compressed to less than [1% of its volume at standard atmospheric pressure](https://afdc.energy.gov/fuels/natural-gas-basics) and stored in specialized cylindrical tanks at pressures ranging from 2,900-3,600 psi. Because CNG has a lower energy density than liquid fuels, it requires larger and heavier [storage tanks](https://blog.psenergy.com/what-to-consider-when-its-time-to-replace-your-underground-storage-tank) to achieve a comparable driving range, which may reduce cargo space in some applications. ### **What Are Natural Gas Vehicles? How Do They Work, and What Are the Options?** NGVs use an internal combustion engine designed or modified to operate on CNG instead of liquid fuels like gasoline or diesel. According to the [U.S. Department of Energy’s Alternative Fuels Data Center](https://afdc.energy.gov/vehicles/natural-gas), 175,000 NGVs were operating in the U.S. as of early 2026. NGVs are available in three configurations: - **Dedicated Natural Gas Vehicles —** Designed to run exclusively on CNG and offer the greatest emissions reductions. - **Bi-Fuel Vehicles —** Equipped with both gasoline and natural gas systems, allowing drivers to switch between fuels as needed; ideal for light-duty fleets or regions with limited infrastructure. - **Dual-Fuel Systems —** Engineered to displace a portion of diesel with CNG, while using diesel for ignition. Primarily used in heavy-duty applications, these systems can be an effective way to reduce costs and emissions without fully transitioning to dedicated NGVs. NGVs tend to be a strong fit for fleets that: - Operate high fuel consumption vehicles - Follow predictable daily routes - Return to a central location for fueling - Operate in areas with access to natural gas infrastructure The [U.S. has one of the largest CNG fueling networks globally](https://transportproject.org/fuel/ngv-station-map/#/find/nearest?fuel=CNG), with approximately 1,600-1,750 CNG fueling stations. Of these, roughly 900-1,000 are public stations, while 700-800 are private fleet stations. Many fleets adopt a hybrid fueling strategy — leveraging public stations for flexibility and private stations to improve cost control and uptime. ### **5 Reasons Fleets Are Exploring Compressed Natural Gas** If you’re considering transitioning to CNG for new vehicle purchases or converting existing vehicles to CNG, the following benefits show why fleets continue to adopt this alternative fuel. ### **Lower and More Predictable Fuel Cost** Natural gas prices have historically been lower and less volatile than diesel and gasoline. For fleets that consume large amounts of fuel, the savings can add up quickly — reducing total cost of ownership (TCO) while providing greater budget stability. ### **Reduced Emissions** Natural gas is the cleanest-burning fossil fuel. Compared to diesel and gasoline, it produces fewer greenhouse gas emissions and significantly reduces harmful pollutants. In many applications, [CNG can reduce greenhouse gas emissions by 15-30%,](https://www.gecf.org/Events-Conferences/Events-HH/ArticleID/632/Expert-Commentary-Future-of-Natural-Gas-in-Road-Transport-and-Its-Role-for-a-Decarbonised-Mobility-Agenda-in-Europe) while lowering tailpipe pollutants such as nitrogen oxides and particulate matter by 70-90% or more. Because it is stored in sealed systems, CNG also produces zero evaporative emissions. ### **Domestic Fuel Supply** Unlike diesel and gasoline, which are influenced by global oil markets, the vast majority of natural gas used in the U.S. is produced domestically — typically 95-98%, with the remainder sourced from Canada. This helps reduce exposure to global oil market volatility, supports more stable and predictable fuel pricing, and strengthens domestic energy security. ### **Cleaner Engine Operation** Because natural gas burns cleaner than diesel and gasoline, it can reduce engine buildup, extend oil life, and support more predictable maintenance — and in some applications may contribute to longer engine life and lower maintenance costs. ### **Quieter Operation** Natural gas engines are typically quieter than diesel engines, making them well-suited for urban environments and early morning or nighttime operations. ### **Compressed Natural Gas Considerations Before Transitioning** CNG offers clear advantages, but it’s not the right fit for every fleet. Before making the transition, take a data-driven approach to your [fuel management](https://psenergy.com/fuel-management/) strategy. Analyze your routes, fuel consumption, infrastructure access, and long-term operational goals. Talk to experienced fleet managers and owners and consult your fuel provider. Key factors to evaluate include: - Vehicle acquisition and conversion costs - Fueling infrastructure availability - Range and duty cycle requirements - Facility readiness Checking all these boxes is critical to making a successful and cost-effective transition to CNG. **Want to explore alternative green fuels?** [**Download your copy of our guide here to learn more.**](https://info.psenergy.com/green-fuels-future-transportation-fleets)   #### Subscribe #### Latest Posts in this Topic - [6 Key Considerations for Procuring Reliable Fuel Delivery](https://blog.psenergy.com/6-key-considerations-for-procuring-reliable-fuel-delivery) - [Curb Weight vs Gross Weight: How They Impact Fuel Efficiency and Fleet Performance](https://blog.psenergy.com/curb-weight-vs-gross-weight-how-they-impact-fuel-efficiency) - [How Winter Weather Affects Fuel Economy](https://blog.psenergy.com/how-winter-weather-affects-fuel-economy) #### Topics - [Fleet Management](https://blog.psenergy.com/topic/fleet-management) - [Fuel Management](https://blog.psenergy.com/topic/fuel-management) - [Asset Management](https://blog.psenergy.com/topic/asset-management) - [Risk Management](https://blog.psenergy.com/topic/risk-management) - [Industry News & Reports](https://blog.psenergy.com/topic/industry-news-reports) #### Address 4480 North Shallowford Rd Suite 100 Dunwoody, GA 30338 #### Phone (770) 350-3000 #### Connect With Us - - - - Energy Services - [Fuel Management](https://psenergy.com/fuel-management/) - [Emergency Fueling](https://psenergy.com/emergency-fueling/) - [Asset Management](https://psenergy.com/asset-management/) - [Green Energies](https://psenergy.com/green-energies/) - Who We Help - [Fleets](https://psenergy.com/fleets/) - [Facilities](https://psenergy.com/facilities/) - [Utilities](https://psenergy.com/utilities/) - [Airports](https://psenergy.com/airports/) - Resources - [Resources](https://psenergy.com/resources/) - [Blog](https://blog.psenergy.com) - [Our Strong Commitment to Supplier Diversity](https://psenergy.com/about-us/) [Get In Touch](https://psenergy.com/contact-us/) PS Energy ![National Minority Supplier Development Council](https://psenergy.com/wp-content/themes/PSEnergyV2/images/nmsdc.png) ![Certified Women's Business Enterprise](https://psenergy.com/wp-content/themes/PSEnergyV2/images/wben.png) ![Women Owned Business](https://psenergy.com/wp-content/themes/PSEnergyV2/images/women-owned.png) Copyright © 2023 PS Energy Group, Inc.
