The BarMar and H2MED projects are paving the way for a sustainable energy future by facilitating cross-border hydrogen pipelines and interconnections. Enagás, GRTgaz, Teréga, and OGE have joined forces for the BarMar project connecting Spain and France, while Enagás and REN collaborate on the Spain-Portugal interconnection. These partnerships aim to conduct feasibility studies, set investment conditions, and establish a joint debt fund to support the projects' development. The H2med initiative seeks to connect the Iberian Peninsula's hydrogen networks with those of France, Germany, and North-Western Europe, emphasizing transnational cooperation and European energy integration. The agreements signed reflect a positive sentiment towards hydrogen as a key player in the transition to sustainable energy sources, showcasing a commitment to fostering renewable energy solutions across borders.
