HyPerLink creates a high-performance grid connection in northern Germany between the import sources and production sites of hydrogen on the one hand and the large industrial consumption centres and underground storage facilities on the other hand. This will create a hydrogen backbone in Germany with a length of around 1000 kilometres, mainly from existing gas pipelines in northern Germany. This backbone network will connect the Netherlands via Oldenburg and Bremen with several industrial cities such as Hamburg, Hanover and Wolfsburg, and with Denmark via Schleswig-Holstein.
