Brightmark RNG Holdings LLC is a U.S.-based renewable energy company focused on producing renewable natural gas (RNG) from organic waste. Formed as a joint venture between Chevron U.S.A. Inc. and Brightmark LLC, the company develops, owns, and operates projects that convert dairy and other agricultural waste into pipeline-quality RNG.
Its projects typically partner with farms to capture methane through anaerobic digestion, upgrade the resulting biogas, and deliver RNG for use in transportation fuel markets or as a renewable gas supply. Brightmark RNG Holdings provides end-to-end project capabilities, including development, financing, construction oversight, and long-term operations, working with agricultural producers, utilities, and fuel marketers to reduce methane emissions and support lower-carbon energy solutions.
