Portugal grid operator Rede Eléctrica Nacional (REN) has registered the first certification of Guarantees of Origin (GO) for biomethane intended for the transport sector.
The certified company was G3 | Go Green Gas which supplies biomethane for heavy transport fleets.
Isabel Fernandes, Director of Energy Services at REN, said this operation confirms the maturity and robustness of the national platform as a benchmark instrument for certifying the renewable origin of gases in Portugal, demonstrating its ability to meet the needs of a rapidly evolving market.
“It also demonstrates, in practice, the interconnection of the Portuguese system with its European counterparts,” she said.
Joaquim Marques, CFO & Head of Business Operations at G3 | Go Green Gas, said the certification is a concrete step towards accelerating the energy transition and the decarbonisation of road transport, and represents the strengthening of a long-standing commitment to mobility based on renewable gases, now carried out within the national system.
GOs are electronic certificates that prove to the end consumer that a given quantity of energy has been produced from a specific source and technology.
In the case of renewable energy, the issuance of these guarantees allows the origin of the energy to be certified, enabling suppliers and end consumers to demonstrate their consumption of renewable energy, particularly in the context of their sustainability strategies and respective reporting obligations.
It will now carry out this certification on the Guarantees of Origin Issuing Entity (EEGO) platform.
The move comes on the eve of the World Biogas Summit which will be discussing latest global market developments in the biogas and biomethane sectors.
