According to ADEME, the potential supply base that could keep France mobile in 2030 is 130 million tons of raw materials destined for anaerobic digestion, or 56 TWh of primary energy in biogas production.
This resource consists mainly of agricultural materials, as well as household, community and sanitation organic waste.
Anaerobic digestion is a natural process. Organic waste is placed in a sealed tank, called a digester. In this tank, microorganisms, which live in oxygen-devoid areas, will "digest" organic matter and produce "biogas". Biogas consists primarily of methane.
Whatever the production process used, the biogas must next be purified to attain natural gas quality: it is then called biomethane.
This biomethane can then be used as fuel, either locally in compressed or liquefied form, or after injection into the natural gas networks to supply sites where it will be consumed. Fuel biomethane is called bioNGV: natural gas for vehicles from renewable sources.
When the biomethane is injected into natural gas networks, traceability is ensured by guarantees of origin. Each injected biomethane megawatt hour produces emissions with an identifiable origin guarantee, thanks to its production location and the waste used. The user thus knows that the gas he or she consumes corresponds to a defined quantity of produced biomethane.
BioNGV use does not require any adaptation of the existing and mature NGV industry sector. BioNGV and GNV are composed of the same molecule and mix indifferently in gas distribution networks, in fuel stations and NGV tankers.
Depending on the needs and uses, NGV and bioNGV are distributed to gas pumps in compressed or liquefied form:
