About Clean Energy Fuels Corp.

Clean Energy Fuels Corp. specializes in providing natural gas as an alternative fuel source and comprehensive fueling infrastructure, primarily serving markets in the United States and Canada. The company supplies various forms of natural gas, including bio-based renewable natural gas (RNG), compressed natural gas (CNG), and liquefied natural gas (LNG), specifically for medium and heavy-duty transportation. Beyond fuel delivery, Clean Energy Fuels offers full-spectrum services for fueling stations, encompassing their design, construction, operation, and ongoing maintenance for both public and private vehicle fleet clients. It also sells and services essential equipment, such as compressors, vital for RNG production and fueling facilities. The company facilitates the distribution and sale of CNG, RNG, and LNG via virtual natural gas pipelines and interconnected systems. In addition to its core operations, Clean Energy Fuels actively participates in the environmental credit market. It sells U.S. federal, state, and local government credits—like Renewable Identification Numbers (RINs) and Low Carbon Fuel Standards (LCFS) credits—generated from the use of RNG as vehicle fuel. Concurrently, it secures grants, credits, and incentives from these governmental entities. A strategic initiative for the company involves the development, ownership, and operation of projects focused on producing RNG from dairy and other livestock waste. Its diverse clientele includes heavy-duty trucking, airports, waste management, public transit, industrial users, institutional energy consumers, and government fleets. As of December 31, 2021, Clean Energy Fuels served approximately 1,000 fleet customers, supporting around 48,000 vehicles. Its expansive network included roughly 548 fueling stations across 42 U.S. states and an additional 25 stations in Canada, which it either owned, operated, or supplied. Clean Energy Fuels Corp. was established in 2001 and is headquartered in Newport Beach, California.
