Lithuania has officially joined the European ERGaR (European Renewable Gas Registry) Hub, according to Amber Grid, the Lithuanian natural gas transmission operator. Amber Grid is the operator of the national renewable gas guarantees of origin registry, and the company announced the integration, which enables the secure and standardised electronic exchange of green energy certificates across European borders.
The partnership arrives as Lithuania’s biomethane sector experiences a significant increase. At the start of 2026, the country reported 12 operational biomethane plants with a combined capacity of 67 megawatt (MW). In the first two months of this year, over 60 gigawatt (GWh) of guarantees of origin were issued—a 2.4-fold increase compared to the same period in 2025. By joining the ERGaR platform, Lithuanian producers gain streamlined access to major green energy consumers, most notably Germany. The system eliminates manual hurdles, enabling certificates to be transferred electronically to German and Danish registries with greater transparency and speed. Lithuania now joins a network that includes Austria, Denmark, Germany, the Netherlands, Slovakia, Switzerland and the United Kingdom.
“Joining the ERGaR Hub opens up new opportunities for Lithuanian biomethane producers to operate in the international market,” said Nemunas Biknius, CEO of Amber Grid. “It creates broader export opportunities for our producers and increases the competitiveness of Lithuanian biomethane globally.”
