Archaea Energy combines industry-leading experts and proven technology with an innovative design and manufacturing approach for RNG projects. This enables us to bring projects to market faster and at a lower cost, and operate projects with higher expected uptime and efficiency, than industry averages.
Our team has extensive experience in project development, engineering, landfill operations, and green gas energy. We develop, construct, own, and operate projects for the entirety of the project lifecycle and expect to deliver a predictable supply of RNG for decades. RNG production transforms landfills and farms into renewable energy centers and generates a royalty which becomes a meaningful, long-term source of revenue for the landfill and farm owners.
Archaea Energy is dedicated to bringing a better RNG solution to landfill owners. A safe, compliant, and reliable operation maximizes uptime and the value of the landfill. In the industry, we stand apart in our understanding of RNG. Our track record of reliability and emphasis on long-term partnerships enables landfill owners to receive benefits from our RNG projects while focusing on their core operations.
We are also seeking to expand our sustainable energy offerings by developing CO2 sequestration and renewable hydrogen opportunities.
Biogas is produced when organic material decomposes in anaerobic conditions. Using proven membrane gas separation technology, biogas can be processed to remove impurities and separate CO2 to produce high-Btu, pipeline-quality RNG, which is a low carbon replacement for traditional fossil fuel-based natural gas.
Sources of biogas for potential RNG production include landfills, animal manure, separated organic waste, and wastewater treatment facilities. Landfills are the largest of these sources and provide an attractive feedstock for RNG because of their very predictable, long-term production profile.
RNG can be used interchangeably with fossil fuel-based natural gas. It is often used as a replacement for diesel fuel in vehicles, for power generation, and as a heating source in buildings. It also has industrial applications and can be used as a feedstock for renewable hydrogen.
Archaea Energy views landfills as long-term energy resources and is committed to partnering with landfill owners to meet their needs while maximizing the value of their landfills. We have extensive biogas processing experience and our experts helped design, build, and develop key gas processing systems utilized in the majority of U.S. RNG facilities in operation today.
Our team applies its unique knowledge of gas separation and nitrogen rejection to either construct a new plant or repair and optimize an existing RNG plant to produce RNG with high uptime and methane recovery. We are experts in turning challenging sites into valuable renewable energy centers in a short timeframe. We also identify opportunities for wellfield and waste optimization.
Four types of LFG collection
Landfill without gas collection system
Methane (CH4) and CO2 are vented to the atmosphere. CH4 is 25X more destructive than CO2 as a greenhouse gas.
Landfill with gas collection and flare
CH4 and CO2 are captured and flared. CH4 is converted to CO2, which is less destructive to the atmosphere, but still results in harmful greenhouse gas emissions. This approach captures up to 80% of the CH4, but it is not used beneficially.
Landfill with gas collection system and Archaea RNG project
CH4 and CO2 are captured and processed. CH4 is upgraded into pipeline-quality RNG that displaces fossil fuels. CO2 is flared. This approach captures and beneficially uses over 90% of the CH4.
Landfill with gas collection system, Archaea RNG project, and carbon capture
CH4 and CO2 are captured and processed. CH4 is upgraded into pipeline-quality RNG that displaces fossil fuels. CO2 is captured and sequestered, further reducing overall emissions. This approach captures and beneficially uses over 90% of the CH4.
Agricultural manure produces biogas, which can be processed and upgraded to produce RNG. Agricultural manure produces biogas with a higher methane content than landfill gas, but with significantly lower gas volumes. RNG projects at farms typically use anaerobic digester technology and produce both RNG and digestate. Digestate can also be sold, creating an extra revenue source for farm owners. Accounting for avoided methane emissions at the farms, RNG produced from animal manure achieves a negative carbon intensity score and is particularly valuable in the transportation fuel market due to crediting mechanisms.
