The SoutH2 Corridor project is a 3,300 km hydrogen pipeline connecting North Africa, Italy, Austria, and Germany. Led by TSOs who each submitted Project of Common Interest submissions to the European Commission, it aims to supply competitive renewable hydrogen to European demand clusters. It utilizes >70% repurposed infrastructure, with new pipeline segments where necessary. The corridor has trilateral political endorsement, as well as strong support from companies involved in production (c. 2.5 Mtpa) and offtake of hydrogen along the whole corridor. The SoutH2 Corridor plays a vital role in enabling the transportation of both imported and domestically produced hydrogen.
