The Gas Transmission System Operators (TSOs) of Finland, Estonia, Latvia, Lithuania, Poland, and Germany’s Ontras have concluded a pre-feasibility study of the Nordic-Baltic Hydrogen Corridor (NBHC) with promising results. The study, which began in January 2024, has laid out the essential requirements for establishing this corridor focused on transporting renewable hydrogen among these nations. By the year 2040, the NBHC aims to facilitate the transportation of up to 2.7 million tons (Mt) of renewable hydrogen annually across these countries. The preliminary findings from the study suggest that the NBHC has the potential to become one of the initial operational cross-border hydrogen pipelines in Europe, depicting a significant milestone for hydrogen infrastructure development. The planned specifications for the NBHC pipeline include a diameter of 48 inches (1,200 mm) and a length of around 2,500 km, complemented by the setup of multiple compressor stations along the route. This initiative marks a crucial step towards boosting the utilization of renewable hydrogen and fostering collaboration in sustainable energy transport across the Nordic-Baltic region.
