Europe had 1,548 biomethane plants in production at the last EBA count. Almost none of them sit where the demand is. A German fuel supplier, a Dutch shipping line and a Swiss utility are all buying gas that was injected somewhere else entirely.
Physically, that works — the European grid moves the molecules. Contractually, it depends on whether the certificate can travel with them. Registries don’t all talk to each other, transfer rules differ by country, and a certificate that is perfectly valid in one member state can be worthless across the border.
This is the part worth settling before signing anything. The gas is a commodity. The transferable proof is what you are actually buying.
bGX connects producers and buyers across Europe and structures the transfer so the certificate arrives intact — covering BEHG, GEG, EU ETS and FuelEU Maritime obligations.
