Clean Energy Fuels Corp. (NASDAQ:CLNE) is a leading provider of renewable natural gas (RNG) and conventional natural gas solutions for the transportation market in North America. The company has established itself as a pioneer in the RNG industry, leveraging its extensive network of fueling stations and strategic partnerships to drive the adoption of this clean energy source.
Business Overview and History
Clean Energy Fuels was founded in 1997 with the goal of developing and operating natural gas fueling infrastructure to support the growing demand for alternative transportation fuels. In its early years, the company played a pioneering role in the commercialization of RNG as a transportation fuel. Over the past two decades, Clean Energy has steadily expanded its operations, acquiring and constructing a network of over 600 fueling stations across the United States and Canada.
The company's growth in RNG sales has been remarkable, increasing from 13 million gallons sold in 2013 to 236.7 million gallons in 2024. This significant expansion was driven by increasing demand for cleaner fuels and Clean Energy's ability to deliver RNG through its extensive fueling network. Despite facing challenges in the late 2000s, including limited market adoption for natural gas vehicles and volatility in commodity prices, Clean Energy remained focused on providing the cleanest fuel solutions to its customers.
A major milestone for the company came in 2018 when it entered into a stock purchase agreement with TotalEnergies, one of the world's largest energy companies. This strategic partnership provided Clean Energy with additional capital and resources to expand its RNG production and fueling infrastructure. The company has also formed successful joint ventures with other industry leaders like bp to develop new RNG projects, further solidifying its position in the market.
In 2014, Clean Energy made a pivotal shift in its business strategy by introducing RNG as a transportation fuel. RNG, which is derived from the capture and processing of biogenic methane, has emerged as a highly attractive alternative to conventional natural gas and diesel, offering significantly lower greenhouse gas emissions and a more sustainable energy source. This strategic move has positioned Clean Energy as a leader in the RNG market, catering to the increasing demand for cleaner transportation solutions.
Financial Performance and Outlook
Clean Energy's financial performance has been marked by both challenges and opportunities in recent years. In the fiscal year 2024, the company reported revenue of $415.9 million, a slight decrease of 2.2% from the previous year's $425.2 million. This decrease was primarily due to lower average fuel prices, partially offset by an increase in total gallons of fuel sold. The company's adjusted EBITDA for the year reached $76.6 million, exceeding the top end of its guidance range of $72 million.
For the fourth quarter of 2024, Clean Energy reported revenue of $109.3 million and a net loss of $29.8 million. The increase in net loss compared to Q4 2023 was primarily due to an $8.1 million impairment of investments in equity securities.
Looking ahead to 2025, Clean Energy has provided a mixed outlook. The company's GAAP net loss guidance range is $81 million to $83 million, while its adjusted EBITDA guidance is $50 million to $55 million. This decline in adjusted EBITDA is primarily attributable to the expiration of the Alternative Fuel Tax Credit (AFTC) in 2024, which contributed approximately $24 million to the company's 2024 results, as well as a projected 20% decrease in average RIN prices. Clean Energy is estimating RIN prices in the $2.40 range for 2025 versus the $3.10 average in 2024, resulting in an approximate $10 million reduction in RIN revenue compared to 2024.
On a positive note, Clean Energy expects California LCFS prices in the low $70s for 2025, up from the $61 average in 2024, which could provide a $2 million LCFS revenue upside. The company's 2025 RNG volumes are projected to be around 246 million gallons, up from 237 million gallons in 2024. Clean Energy's 2025 consolidated revenues are expected to be around $400 million.
Despite these near-term challenges, Clean Energy remains optimistic about its long-term growth prospects. The company is focused on expanding its RNG production capabilities, having recently announced several new dairy RNG projects and a joint development agreement with Maas Energy Works. These initiatives are expected to contribute to the company's future RNG volumes and profitability.
Operational Highlights and Competitive Landscape
One of Clean Energy's key operational highlights in recent years has been the growing adoption of its RNG fuel by major transportation fleets. The company has secured contracts with numerous large shippers, manufacturers, and retailers, including Amazon, Pepsi Frito-Lay, FedEx, and Anheuser-Busch, among others. This broad customer base underscores the strong demand for RNG in the heavy-duty trucking, transit, and refuse markets.
Clean Energy's business model encompasses the full value chain of the natural gas vehicle fuel market, from RNG production and supply to station construction and operations, as well as the generation and sale of valuable environmental credits. In 2024, RNG sales made up 89% of the company's total vehicle fuel sales, up from 12% in 2013, reflecting the growing demand for this lower-emission fuel. Clean Energy believes it provided 50% and 39% of the RNG used for transportation fuel in California and the U.S., respectively, during 2024.
The company's efforts to expand its RNG production have also yielded positive results. As of the end of 2024, Clean Energy had six RNG projects in operation, with two more projects under construction and four additional projects in development. These projects are expected to contribute 4 million to 6 million gallons of RNG to the company's fuel volumes in 2025.
In addition to fuel sales, Clean Energy generates revenue from environmental credit sales, including Renewable Identification Numbers (RINs) and Low Carbon Fuel Standard (LCFS) credits. In 2024, the company estimates it generated 39% of all D3 RINs in the U.S. and 42% of all LCFS credits under the Bio-CNG and Bio-LNG pathways in California. The sale of these environmental credits has become an increasingly important revenue stream for Clean Energy, representing $48.9 million, or 11.8% of total revenue, in 2024.
Clean Energy also provides operations and maintenance (O&M) services for public and private vehicle fueling stations. In 2024, the company serviced 263.2 million GGEs at facilities it does not own, generating $56.9 million in O&M services revenue. Additionally, Clean Energy designs, constructs, and sells or leases natural gas fueling stations to customers. In 2024, station construction sales accounted for $25.2 million, or 6.1%, of the company's total revenue.
In the competitive landscape, Clean Energy faces challenges from other alternative fuel providers, including renewable diesel, biodiesel, and electric vehicle manufacturers. However, the company's extensive fueling infrastructure, strategic partnerships, and focus on RNG production have allowed it to maintain a strong position in the market. The introduction of Cummins' X15N natural gas engine, which is designed for heavy-duty trucks, also presents a significant opportunity for Clean Energy to drive further adoption of RNG in the trucking industry. However, the company is not anticipating significant incremental volumes from the launch of this engine in 2025, expecting only 3-5 million gallons from over 25 fleets.
