Archaea Energy LLC is a U.S.-based renewable energy company that develops, builds, owns, and operates projects to capture and upgrade biogas—primarily landfill gas—into renewable natural gas (RNG) and electricity. Its facilities collect raw landfill gas, remove contaminants, and refine it to pipeline-quality methane for use in transportation, utility, and industrial markets.
The company manages a portfolio of RNG and landfill-gas-to-energy plants across the United States and participates in environmental credit programs such as RINs and LCFS where applicable. Archaea Energy is known for standardized, modular plant designs intended to accelerate project deployment and improve reliability. Headquartered in Houston, Texas, it became a subsidiary of bp in 2022. Its activities support lower-carbon energy supply and can provide a drop-in methane feedstock for industrial and chemical applications seeking to reduce lifecycle greenhouse gas emissions.
