Company Description
Clean Energy Fuels Corp. (NASDAQ: CLNE) is a utilities-sector company focused on natural gas distribution for the transportation market. According to company disclosures and recent press releases, Clean Energy describes itself as the country’s largest provider of the cleanest fuel for the transportation market, with a mission to decarbonize transportation through the development and delivery of renewable natural gas (RNG). RNG is produced by capturing methane from organic waste and using it as a transportation fuel.
The company operates as a natural gas marketer and retailer in the United States and Canada. As outlined in third-party and company information, Clean Energy supplies compressed natural gas (CNG) and liquefied natural gas (LNG), with the majority of its revenue historically generated in the U.S. and largely consisting of compressed natural gas. It purchases natural gas from local utilities, then compresses, cools, or liquefies it at company-owned plants and sells the resulting fuel through both company-owned and customer-owned fueling stations.
Clean Energy’s target markets include heavy-duty trucking, airports, public transit, institutional energy users, and government fleets. Company press releases state that thousands of vehicles, from airport shuttles to city buses to waste and heavy-duty trucks, use its fuels to reduce climate-harming greenhouse gas emissions. The firm also builds, operates, and maintains natural gas fueling stations for customers, and provides operations and maintenance (O&M) services at facilities it does not own, generating service revenue alongside product revenue from fuel and environmental credits.
Renewable Natural Gas (RNG) Focus
Recent company communications emphasize RNG as a central focus of Clean Energy’s strategy. RNG is described as a sustainable fuel derived from capturing methane from organic waste, such as dairy manure. Multiple press releases highlight RNG production projects at dairy farms and joint developments with partners. For example, Clean Energy has broken ground on several dairy RNG production facilities under a development agreement with Maas Energy Works, spanning dairies in South Dakota, Georgia, Florida, and New Mexico. These projects are intended to capture methane from tens of thousands of dairy cows and convert it into RNG for transportation use.
The company has also completed a major RNG facility at South Fork Dairy in Dimmitt, Texas, which it financed and now operates. This facility processes dairy manure through anaerobic digesters and advanced gas conversion equipment to produce pipeline-quality RNG that is injected into an interstate natural gas pipeline. The project has received approval from the U.S. Environmental Protection Agency to generate Renewable Identification Numbers (RINs) under the federal Renewable Fuel Standard, and the company expects to generate Low Carbon Fuel Standard (LCFS) credits in California. Clean Energy states that RNG used as a transportation fuel can significantly lower greenhouse gas emissions on a lifecycle basis compared to diesel and can achieve negative carbon-intensity scores by reducing emissions both at the source and at the vehicle.
Fueling Network and Operations
Clean Energy reports that it operates a large network of fueling stations across the U.S. and Canada, where RNG and conventional natural gas are dispensed as CNG and LNG. Company press releases reference a network of over 600 stations that can be supplied with RNG produced from its projects and partners. The company also owns and operates LNG plants in California and Texas that supply bulk LNG to various customers, including marine, energy exploration, power generation, and space-related companies.
In addition to selling fuel, Clean Energy provides station construction services and ongoing maintenance. Recent disclosures show station construction revenue and O&M service revenue as distinct components of total revenue. The company designs, builds, and maintains fueling stations for transit agencies, municipalities, and private fleets, including both RNG and hydrogen fueling infrastructure. For example, Clean Energy has been awarded contracts to design, build, and maintain hydrogen fueling stations for transit agencies such as Foothill Transit and Gold Coast Transit District, while also maintaining their natural gas stations and supplying RNG for bus fleets.
Customer Segments and Use Cases
Clean Energy’s customer base spans multiple transportation sectors. Press releases describe agreements with refuse haulers, transit agencies, trucking fleets, milk cooperatives, uniform service providers, and other commercial and institutional users. These customers use RNG and natural gas to fuel heavy-duty trucks, buses, and vocational vehicles. The company also supplies bulk LNG to customers in sectors such as space exploration and power generation, where high-purity LNG is used for rocket engine testing or energy-related transport.
Examples of customer relationships include fueling agreements with milk cooperative United Dairymen of Arizona for RNG-fueled trucks, RNG supply and station upgrades for Atlantic City Jitney Association’s shuttle buses, and RNG supply contracts with refuse and recycling companies. Clean Energy has also entered into agreements with space companies for high-purity LNG to support rocket engine testing and spacecraft operations, and with a power generation company for bulk LNG to support transport of materials for advanced energy solutions.
Technology and Demonstration Programs
Clean Energy has launched demonstration programs to promote adoption of natural gas engines powered by RNG in heavy-duty trucking. One initiative involves a Freightliner Cascadia Gen 5 day cab equipped with the Cummins X15N natural gas engine. The company organizes demo truck programs that allow fleets to operate these vehicles in real-world conditions and fuel at Clean Energy’s RNG stations. The programs are intended to showcase performance characteristics such as torque, handling, and fuel cost savings when running on RNG, and to highlight the emissions benefits of using RNG in place of diesel.
Company commentary describes the Cummins X15N engine as designed to run on RNG derived from organic waste and presents it as a lower-carbon alternative to diesel engines. Clean Energy reports that major carriers have placed orders for this engine and that fleets can achieve substantial emissions reductions while benefiting from fuel priced at a discount to diesel, based on the company’s statements.
Revenue Streams and Business Model
Clean Energy’s reported revenue sources include fuel sales, environmental credits, station construction, and services. The company’s volume-related product revenue primarily consists of sales of RNG and conventional natural gas (in the form of CNG and LNG), as well as sales of RINs and LCFS credits and changes in the fair value of derivative instruments related to its truck financing program. Station construction sales and O&M service revenue contribute additional income streams. Company filings and earnings releases detail how these categories contribute to total revenue, without relying on specific forward-looking projections.
The company also participates in equity method investments related to RNG projects, including dairy RNG facilities, and reports associated income, depreciation, interest, and investment tax credit amortization. In some periods, Clean Energy has monetized investment tax credits (ITCs) from dairy RNG projects through sales, generating cash proceeds to support further investments in RNG production.
Corporate and Regulatory Context
Clean Energy Fuels Corp. is incorporated in Delaware and lists its common stock on the Nasdaq Global Select Market under the symbol CLNE, as reflected in its SEC filings. The company files periodic reports and current reports with the U.S. Securities and Exchange Commission, including Forms 10-Q, 10-K, and 8-K. Recent 8-K filings have covered topics such as quarterly financial results and changes to the board of directors, including appointments and resignations of directors associated with a significant shareholder, TotalEnergies Marketing Services SAS.
According to company statements, a subsidiary of TotalEnergies SE acquired a substantial ownership position in Clean Energy through a stock purchase agreement, with associated director designation rights. Subsequent 8-K filings describe the appointment and later resignation of TotalEnergies representatives on Clean Energy’s board, and the company has entered into indemnification agreements with its directors in line with its standard practices.
Environmental and Policy Positioning
Clean Energy frequently frames its activities within the context of greenhouse gas emissions reduction. Citing data from the U.S. Environmental Protection Agency, the company notes that agriculture and transportation account for significant portions of U.S. greenhouse gas emissions. By capturing methane from farm waste and using RNG as a transportation fuel, Clean Energy positions RNG as a way to lower emissions compared to diesel on a lifecycle basis. The company also highlights that RNG can qualify for negative carbon-intensity scores under certain regulatory frameworks because it reduces emissions at both the source and the vehicle.
In public statements, Clean Energy characterizes RNG as an immediate and cost-effective clean transportation fuel option and references legislative recognition of RNG production in policy discussions. The company’s projects and customer agreements are presented as responses to fleet demand for lower-carbon fuels that can be integrated into existing operations using established engine and fueling technologies.
