First step toward climate-neutral energy supply for industry: Call for interest on hydrogen requirements in the Southern Upper Rhine region

Joint call for interest by GRTgaz, terranets bw an badenovaNETZE | H2 call for expression of interest along the planned RHYn and RHYn Interco cross-border link from September 18, 2023 onward

Bois-Colombe | Stuttgart | Freiburg, 18.09.2023 Preparations for a climate-neutral energy supply for industry are becoming concrete. Together, the network operators GRTgaz and terranets bw as well as the badenova subsidiary badenovaNETZE launch a call for interest for the RHYn and the RHYn Interco hydrogen projects.  Through a cross-border connection to the H2 backbone in France and the conversion of existing gas pipelines to hydrogen, the project partners are creating the conditions for a climate-neutral energy supply for industry.

This cross-border initiative is part of the European project Hydrogen Backbone, a European backbone aimed at ensuring security of supply for hydrogen consumers in Europe and which plans for 2040 a 53,000 km hydrogen network connecting 28 European countries.

From September 18th, 2023 to November 17th, 2023, the project partners will launch a call for interest for hydrogen demand and generation potential in the Southern Upper Rhine region (Germany) and the Grand Est region (France).

The call for interest of the project partners is targeted at companies in the Southern Upper Rhine region (Germany) and Grand Est (France) that plan to produce or purchase hydrogen in large quantities. Specifically, on the German side, the districts of Freiburg, Breisgau-Hochschwarzwald, Emmendingen and Ortenau are addressed.

Interested parties can register their hydrogen needs and production capacities via an online form: 

In the next step, the project partners review the reports received. If there is potential for a connection at RHYn Interco, a feasibility study for a grid connection will be carried out if required. 

The infrastructure is currently scheduled to be commissioned by 2028.
