mosaHYc Moselle-Saar-Hydrogen-Conversion

The mosaHYc project involves the construction of a cross-border hydrogen infrastructure between Saarland and the French region of Grand Est with a total length of around 90 kilometers. In the German section, a new hydrogen pipeline with an internal diameter of approximately 60 centimeters will be built between Leidingen and Dillingen an der Saar, and an existing pipeline between Völklingen-Fürstenhausen and Carling will be reactivated. The network connects electrolysers at the Carling, Fenne, and, in the future, Perl sites with industrial customers in the greater region. The project is being carried out by Creos Deutschland Wasserstoff GmbH in cooperation with the French network operator naTran. In July 2024, the Federal Ministry for Economic Affairs and Climate Protection approved funding of €44 million, of which around €31 million will come from federal funds and the remainder from the Saarland. Construction is scheduled to begin in early 2026, with commissioning planned for the end of 2027.
