The Directorate-General for Energy in Portugal announced the upcoming injection of renewable gases into the Portuguese National Gas System (NGS) within the next 36 months. Through a renewable gas auction, biomethane and renewable hydrogen projects were awarded, totaling 1,990 MWh/year and 119,280 MWh/year respectively. This initiative, funded by the Portuguese Environmental Fund, aims to integrate renewable gases into the gas network, contributing to decarbonisation objectives. REN has been at the forefront of this transition, implementing the H2REN Programme to certify its infrastructure for hydrogen-gas blends transportation. The certification process confirmed REN's readiness to transport up to 10% hydrogen-gas blends in the NGTN and AS Carriço, and up to 20% in the NGDN. By aligning with EU policies, Portugal emphasizes decarbonisation of gas infrastructure as a strategic goal. REN's strategy focuses on adapting existing infrastructure and developing dedicated hydrogen infrastructure to support market demands and drive the energy transition forward.
