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.
Cleaner
As a sustainable biofuel, RNG dramatically reduces carbon emissions versus diesel.
Affordable
RNG is a domestically produced, stable-priced fuel that costs significantly less than diesel.
Proven
RNG is trusted by major fleets like UPS, Amazon, WM, LA Metro, and NYMTA.
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.
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.
Fast-fill
Time-fill
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.
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.
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.
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.
We have the largest technical support team in the industry with over 150 service technicians, all of whom are Clean Energy employed, local, trained, certified, and on-call 24/7/365. We also keep over $20M in critical spare parts inventory stored in Clean Energy warehouses throughout North America to reduce any repair or maintenance downtime. Our full-service partnership provides complete station and equipment management, including remote, round-the-clock monitoring; regular safety and quality inspections; preventative maintenance; and timely, expert repair.
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.
Navigating sustainability and carbon accounting can be complex. Our in-house team is here to help with emissions reporting, providing tools and insights to support your sustainability strategy.
Federal, state, and local grant opportunities exist to offset the cost of switching to renewable natural gas. At Clean Energy, we have a dedicated team available to help you navigate the grant application process and maximize your incentive award. We even have our own incentive programs, like the California RNG Fleet Fund, to help offset the cost of new heavy-duty RNG trucks.
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.
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.
