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.
We are also seeking to expand our sustainable energy offerings by developing CO2ꦗ 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.
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.
