BadenovaNETZE is planning a hydrogen pipeline from Grenzach-Wyhlen to Waldshut-Tiengen to make hydrogen accessible to industrial and logistics companies on both sides of the High Rhine. The H2@Hochrhein pipeline project is intended to form the backbone of the future hydrogen supply along the High Rhine and at the same time connect Baden-Württemberg to the national and European hydrogen infrastructure.

The project became part of the hydrogen core network on October 22, 2024 with the approval of the Federal Network Agency.

The first construction phase consists of a hydrogen pipeline around 9 kilometers long along the High Rhine from Dogern in the Waldshut district to Albbruck, which is part of the “Climate protection and value creation through hydrogen (KWH2)” funding program of the Ministry of the Environment (H2-DNA). Construction work has been underway here since March 2025 and the first section was successfully laid in April 2025. The hydrogen required is produced by the 50 MW electrolyser at the run-of-river power plant in Albbruck by project partner RWE (see H2@Hochrhein project).
