[H1] Renewable natural gas. Decarbonization in the fast lane.
Renewable natural gas (RNG) is an affordable transportation fuel made from organic waste that drastically reduces carbon emissions versus diesel at a fraction of the price. Unlike conventional natural gas, renewable natural gas is not a fossil fuel and does not involve drilling or fracking.
Clean Energy is the largest provider of renewable natural gas for the transportation industry in North America. We produce RNG at dairy farms nationwide and then distribute it through our extensive network of 600+ fueling stations, ensuring convenient access for the 50,000 heavy-duty trucks, buses, and large vehicles running on RNG daily.

[H1] The best fuel for the planet. And your budget.
Renewable natural gas (RNG) is a mature and dependable solution that’s been fueling the transportation industry for over a decade. Major fleets across all sectors – from refuse to transit to heavy-duty trucking – rely on RNG as their workhorse alternative fuel because of its significant environmental and economic benefits.
[H3] Cleaner
As a sustainable biofuel, RNG dramatically reduces carbon emissions versus diesel.
[H3] Affordable
RNG is a domestically produced, stable-priced fuel that costs significantly less than diesel.
[H3] Proven
RNG is trusted by major fleets like UPS, Amazon, WM, LA Metro, and NYMTA.
[H2] RNG for the long haul.
The Cummins X15N engine is revolutionizing the heavy-duty trucking industry. With power ratings up to 500 hp, torque up to 1850 lb-ft, and a 750+ mile range, RNG-fueled vehicles now stand on equal footing with their diesel counterparts in terms of performance, while racing ahead in sustainability.
Curious if the X15N has what it takes to meet the needs of your operations? Clean Energy has two X15N day cab demo trucks making their way around the country: a 2025 Peterbilt 579 and a 2026 Freightliner Cascadia.

[H2] What kind of RNG fueling solution is right for you?
For nearly three decades, Clean Energy has built and maintained natural gas fueling stations across North America. We know what it takes to transition your fleet to RNG, whether it’s a fueling agreement that leverages our public network of fast-fill stations, or developing a private station designed to suit your operations.
[H4] Fast-fill
[H4] Time-fill
[H2] Turnkey solutions for your fleet.
There’s a lot to consider when switching to an alternative fuel like RNG. Our full-service team is here to make the transition as easy, seamless, and cost-effective as possible. We can discuss preferred fuel pricing for your fleet, assess whether a private station makes sense for your operations, advise on sustainability reporting, and even help you apply for grant funding. Our in-house suite of services is unmatched in the industry.

Fueling agreements

With a Clean Energy fueling agreement, fleets can leverage our public station network at wholesale rates, with preferred pricing based on fleet size and fuel volume. Use our Clean Energy fuel card or popular fleet cards like Comdata, EFS, and WEX—and manage your account all through our Customer Portal with visibility into real-time fuel usage, invoicing, and more.

RNG supply

Clean Energy manages one of the largest RNG supply portfolios, with production facilities of various sizes and scale at landfills and dairy farms across North America. Our robust supply volumes ensure transportation customers receive predictable supply throughout our fueling network. In 2024 alone, we delivered 236 million gallons of RNG to the U.S. transportation market. Of that, 128 million gallons were used in California, accounting for more than 50% of the total RNG consumed in the state’s natural gas vehicle fuel market. Not only is our portfolio one of the largest, but it also includes some of the lowest carbon intensity RNG in the market, which the largest fleets in the nation rely for meeting their sustainability goals.

Station design, engineering, & construction

Depending on your fueling needs, it may be beneficial to build your own station. We offer complete station integration services to design, construct, and commission your fueling stations and facilities. With over 30 years of experience across all types of fueling (fast-fill and time-fill), and all forms of natural gas: compressed (CNG), liquified (LNG), and a combination of the two (LCNG), we can tailor a solution to best fit the needs of your operations.

Facility modifications

Making cost-effective modifications to your existing maintenance and parking facilities is an essential part of switching to natural gas vehicles. Our team evaluates your need for ventilation, electrical, heating, monitoring, and detection systems, ensuring your facility will meet local and national code requirements. We can also create a customized Facility Inspection & Testing (FIT) Service Program to assess the functionality, performance, and overall health of your system. Our NGV Easy Bay™ is the first natural gas vapor leak barrier developed specifically for NGV maintenance facilities. It’s a low-cost, code-compliant solution that’s scalable and retractable.

Fleet training program

We’ve partnered with the Alternative Fuels Vehicle Institute (AFVi)© to develop a comprehensive customer care program called Touchpoint. Touchpoint is designed to make the operational transition to natural gas vehicles as easy and seamless as possible by providing a training platform for fleet managers, supervisors, and technicians. Touchpoint ensures all details are properly coordinated for a successful vehicle launch and provides on-going support through the first year of operation.

Mobile RNG fueling

If you’re looking for immediate, flexible, or temporary RNG fueling solutions, particularly when permanent station infrastructure is either unavailable or under construction, Clean Energy can deliver RNG to your fleet. RNG will be delivered to your site in tube trailers and connected directly to on‑site compressors and dispensers, functioning just like a traditional fueling station but without the need for pipeline access.

[H2] What fleets are saying.
“The world has a trash problem. And the world has an emissions problem. Renewable natural gas, produced naturally from bio sources such as landfills and dairy farms, not only turns trash to gas, but it turns it into clean gas. Since RNG is supported by existing national infrastructure used to transport natural gas, it’s a winning solution that will help UPS to reach our ambitious sustainability goals.”
-Mike CasteelUPS Director of Fleet Procurement

[H2] Dairy farms fuel our future.
Turning agricultural waste into renewable natural gas (RNG) is a win-win for farms: it generates an additional source of income and also mitigates the methane emissions from livestock manure. The process of building digesters and processing biogas, however, can be a daunting endeavor. We’re here to help. As a leading producer of RNG, we actively invest in dairy projects across the country. Our team will guide you through the process of financing, developing, and operating anaerobic digesters.

From planning and design through to construction and commissioning, the South Fork Dairy facility processes up to 300,000 gallons of manure each day, capturing and preventing harmful methane from entering the atmosphere and transforming it into clean-burning RNG.
[H2] What dairies are saying.
“Del Rio is a family-owned and operated dairy with multiple generations of Ginggs involved in running it. We take great pride in the sustainable way in which we operate. By adding a RNG digester to our operation, we will be able to say to future generations that we are helping to address serious climate issues that impact the world they live in.”
– Rocky GinggDel Rio Dairy, Texas
