The latest news from GGCS

What should I call it?

Posted: 28 February, 2020. Written by Jesse Scharf

The world of green gas has developed its own language and there is plenty of room for confusion. Here are some terms the GGCS uses and others you may find in use around the sector…

Green Gas has been defined in the GGCS Scheme Rules as “a gas produced from a renewable source, that has lower GHG emissions from its production and consumption than an equivalent fossil fuel product”

Primarily the Green Gas GGCS deals with is Biomethane, being methane produced from the anaerobic digestion of biomass. We also issue RGGOs for Biopropane however as customers are used to the term LPG we have adopted the term BioLPG in our work with Calor Gas.

Some other terms…

BioCNG is a term in common use but Compressed Biomethane would be more accurate. You may also see CBG being used,  being Compressed BioGas

BioLNG is a term in common use but Liquefied Biomethane would be more accurate.

BioSNG – this is  expanded to Bio Substitute Natural Gas or to Bio Synthetic Natural Gas. It is methane produced by the gasification of biomass or fossil based inputs e.g. black bag waste containing food and paper (bio) but also plastic waste (fossil) and therefore might not always be renewable. Where the input is biomass then you may see it referred to as Biomethane from Gasification

Landfill Gas – this could equally be referred to as Biomethane the only difference being that the anaerobic digestion of the biomass takes place in a landfill rather than in a facility designed to produce bimethane. 

Natural Gas – to distinguish it from renewable or green gas this is increasingly being referred to as Fossil Gas
