Work package 4, led by AIB, the Association of Issuing Bodies, will establish Guarantees of Origin from different renewable gas technologies and develop verification standards for Power-to-Gas and Biomethane to Bio-LNG/Biomethanol. It will also compare the technical, organisational and operational differences in the hub systems of biomethane/renewable gas (ERGaR) and renewable electricity (AIB). The work package will also assess and coordinate the conversion of electricity GoO to biomethane/renewable gas/hydrogen GoO from a technical and organisational perspective.
