Learn more about Renewable Natural Gas, its use and impact on the environment.
RNG is a high-BTU, pipeline quality biomethane that is derived from organic waste materials. It is processed to be fully interchangeable with fossil-based natural gas and is delivered through the existing or mobile pipeline infrastructure.
When organic material* decomposes in anaerobic conditions a gas is produced that is often referred to as biogas. Biogas is processed to remove impurities, CO2 and the remaining contaminants which increases the methane content to reach pipeline specifications for natural gas. The resulting product is RNG.
*Organic material can be sourced from landfills, livestock operations, and water treatment plants, among other organic waste sources. It is either collected and processed at the landfill site or in an anaerobic digester.
The United States generates millions of tons of waste each year from which biomethane can be derived to create RNG. Only a fraction of the gas produced from waste is currently being used to produce biomethane. As a result, there is significant future potential for the expansion of RNG. It is estimated that from 780,000 million to 1,400 billion cubic feet (BCF) of biomethane could be produced from sources requiring anaerobic digestion, such as landfills and manure.
Extremely reliable. RNG is made from biogas, and biogas is created 24/7 by natural anaerobic digestion. Most of our sites are interconnected through the national pipeline network, and an extended outage at one RNG plant can be covered by other RNG plants.
RNG's environmental benefits have tremendous value. The gas has value in the federal Renewable Fuel Standard market - generating D-3 RINs, state program benefits (California, Oregon) as well as carbon offsets. The value of those credits today can be worth well over $15/MMBtu. Archaea can structure an agreement to enable customers to monetize RNG credits for a period of time and then transition the RNG to use for offsetting Scope 1 (direct) emissions.
By using a fuel that’s made using organic waste, RNG serves as a near-term solution to a cleaner energy future. Using RNG as opposed to traditional fuels will help reduce emissions and brings us closer to a greener future.
In a landfill, naturally-occurring anaerobic digestion of organic matter produces biogas over a 30-50 year timeframe. About half of this gas is methane, which if not collected escapes into the atmosphere where it is 25 times more destructive than CO2 as a greenhouse gas. Modern landfills with strong collection and processing systems can purify this gas up to pipeline quality renewable natural gas.
Solid waste landfills are the third-largest source of methane emissions, and it is often more economical to collect LFG relative to other waste sources. Landfills produce biogas in a concentrated area which can be contained, purified at the source, and delivered directly into pipelines. LFG also creates several potential revenue sources.
Landfills are retrofitted to direct biogas to processors which convert LFG into a purified RNG.
