Green Gas
Green Gas (collectively biomethane, renewable gas or biogas) is renewable gas produced from various types of biodegradable material. It can be upgraded to the quality of natural gas and injected into grid networks, allowing it to be consumed in the same way as natural gas
Biomethane certificates allow buyers to document the renewable origin of the gas volumes they purchase. Whether and how this can be reported as an emissions reduction depends on the accounting framework applied (e.g. GHG Protocol, SBTi, or national reporting schemes) and on the feedstock. We can help you assess the options
Green gas can be produced from various types of sources like biodegradable feedstock and landfill gas
Proof of Origin
Biomethane is typically combined with a proof of origin certificate which enables the subsequent tracing of a quantity of biogas back to its origin
The proof of origin contains data identifying aspects such as the place of production and the first feeding in a quantity of biogas. It will always relate to an individual biogas plant and includes, among other specifications, the entry point number and the address of the production facility
European Registries for Green Gas
Ã… Energi has – as an active trader of biogas certificates – an account in the German biogas registry (dena Biogasregister). We are able to receive, transfer, and redeem certificates on your behalf
Currently, transfers are permitted between dena’s Biogas Register Germany and the following registries (bilateral cooperation). Further connections are active via ERGaR (European Renewable Gas Registry)
- Biomethane Register Austria (AGCS)
- ENERGINET Denmark
- Green Gas Certification Scheme (GGCS)
