Find out if natural gas is ususally with or without a share of biogas and if we need this level of detail #149

Germany: In 2021, the total gas consumption in Germany was about 1,000,000 GWh (Bundesnetzagentur 2022, https://www.bundesnetzagentur.de/DE/Gasversorgung/aktuelle_gasversorgung/Rueckblick/start.html).

In the same year, about 10,000 GWh of biogas were put into the German gas networks (Bundesnetzagentur 2022, Monitoringbericht 2022, https://www.bundesnetzagentur.de/SharedDocs/Mediathek/Monitoringberichte/MonitoringberichtEnergie2022.pdf?__blob=publicationFile&v=5).

So only about 1 % of the gas in the network was biogas --> can be neglected

Denmark: 25 % of the gas in the gas network is biogas (https://en.energinet.dk/About-our-news/News/2022/01/07/New-record-biogas/) UK: Under 1 % of gas in Britain is biogas (https://ixoraenergy.co.uk/biomethane-offers-rapid-and-safe-alternative-to-expensive-imported-natural-gas/)

CONCLUSION: The difference between the emission factors for natural gas (with limited biogas content) and natural gas (100% mineral blend) in the UK GHG conversion factors is only about 0.4 %. So for now, decision to just use the normal natural gas emission factor with limited biogas content.
