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.
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.
Bioenergy is a type of renewable energy that is derived from plants and animal waste. [1] The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2]
A bio-digester is a mechanized toilet that uses decomposition and sedimentation to turn human waste into a renewable fuel called biogas. Biogas can be made from substances like agricultural waste and sewage. [92] [93] The bio-digester uses a process called anaerobic digestion
Ethanol's chemical composition. Similar to other gasoline structures, biodiesel is built from a foundation of hydrocarbons. BG100, or 100% biogasoline, is formulated so that it can immediately be used as a drop-in substitute for petroleum-derived gasoline in any conventional gasoline engine, unlike ethanol.
Biomass includes: "biogas, biomethane, landfill gas and sewage treatment gas and from the biologically degradable part of waste from households and industry". [2]: § 5(14) Mine gas is in a separate category. Germany's national energy policy is set out in the government's Energy Concept released on 28 September 2010. [17]
