Energinet has pushed back its plans to construct a hydrogen pipeline connecting Denmark and Germany from 2028 to 2031.

The Danish state-owned transmission system operator (TSO) said that despite “large potential” for the infrastructure, projects with “significantly different degrees of maturity” forced it to delay the development.

Originally planned to be operational by 2028, the development intends to carry green hydrogen produced in Denmark’s clusters around Fredericia, Esbjerg and Holstebro, into Germany and beyond, feeding into the European Hydrogen Backbone.
