Biogas is a renewable energy source that can supply energy for various applications. It is primarily composed of methane and carbon dioxide, along with trace gas elements. Biogas is generated through the anaerobic digestion of organic matter. This digestion process occurs naturally in landfills as the organic material breaks down. As landfill gases are produced, they are captured and transported through a network of wells and pipelines within the landfill system.
In agricultural settings, biogas is produced and collected from the decomposition of livestock waste, crop residues, wastewater sludge, and food processing waste using a biodigester.
After the gas is captured in both landfill and agricultural environments, it undergoes a purification process. This process removes carbon dioxide and other non-methane components, resulting in valuable biomethane, also known as Renewable Natural Gas (RNG).
Ariel's RNG compressors play a crucial role in the methane-capturing process. Once compressed, the gas can be used for on-site power generation or as a fuel source for CNG vehicles. It can also be injected into existing natural gas pipelines to help power the energy grid for electricity and heating in homes and businesses.
RNG is chemically identical to conventional pipeline gas and is the only alternative fuel that can be produced as carbon negative when following best practices.
