Natural gas pipeline along the coast – The Wilhelmshaven Coast Line
The Wilhelmshaven Coast Line has been designed as an innovative dual pipeline system. One of the two 9 km pipeline legs will feed natural gas into the German gas transmission pipeline network.

The Wilhelmshaven Coast Line for natural gas will run along the coast at Wilhelmshaven alongside the planned Wilhelmshaven Coast Line for hydrogen. Construction is scheduled to start in 2026.
