The most common way of collecting biogas with which to produce biomethane is through the process of anaerobic digestion. Multiple ways of methanizing carbon dioxide/monoxide and hydrogen also exist, including biomethanation, the Sabatier process and a new electrochemical process pioneered in the United States currently undergoing trials.

In this way, the production of renewable gas can be phased in at the same rate as the production capacity is increased. The gas market and infrastructure the natural gas has contributed with is a condition for large scale introduction of renewable biomethane produced through anaerobic digestion or gasification and methanation bio-SNG.
This process can be applied in a power-to-gas system to produce biomethane and is appreciated as an important storage technology for variable renewable energy in the context of energy transition. [1] This technology was successfully implemented at a first power-to-gas plant of that kind in the year 2015.
Biogas is a gaseous renewable energy source [1] produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester, biodigester or a bioreactor.
During a three-hour presentation at a Tokyo hall Tuesday, the car manufacturer giant announced it would offer lean compact engines that also run on so-called green fuels like hydrogen and ...
Biogas is a mixture composed primarily of methane and carbon dioxide produced by the process of anaerobic digestion of organic material by micro-organisms. Other trace components of this mixture includes water vapor, hydrogen sulfide , siloxanes, hydrocarbons, ammonia, oxygen, carbon monoxide, and nitrogen.
Naturally occurring methane emissions, typically called landfill gas or biogas, are not clean enough to be introduced directly in the US National Natural Gas Pipeline system, but technology to do so has been developed. [48] The pipeline quality gas is called Renewable Natural Gas (RNG).
A biogas upgrader is a facility that is used to concentrate the methane in biogas to natural gas standards. The system removes carbon dioxide, hydrogen sulphide, [1] water and contaminants from the biogas. One technique for doing this uses amine gas treating. This purified biogas is also called biomethane. It can be used interchangeably with ...
