mosaHYc

MosaHYc is a project involving 90 km of hydrogen grid in France and Germany, conducted in partnership with CREOS Deutschland. It will build from the conversion of around 70 km of gas pipelines between Saarland (Germany), Lorraine (St Avold) and the Luxembourg border to develop a regional hydrogen hub.
The value chain around mosaHYc (production and consumption) has been structured within an Economic Interest Grouping (GEIE): the "Grande Région Hydrogen" (GRH).

This project was financed by the State as part of France 2030 operated by ADEME.

The first purposes will be industrial uses for players in the Carling industrial platform (France) and steel factories located in the region, especially in Dillinger Hütte (Germany).

Hydrogen mobility  will benefit from the scale effects arising from the industrial ecosystem. Lastly, electricity production will make it possible, thanks to the storage capacity of hydrogen, to smooth the production of renewable electricity.

• 08/2021: European Economic Interest Grouping "Grande Région Hydrogène" (GRH) created.
• 06/2022: Feasibility study ends (funded by the regional ADEME Grand-Est).
• 09/2022: Basic studies launched.
• 05/2023: Winner in ADEME "Technological bricks and hydrogen demonstrators" call for projects (funded by the Government as part of the France 2030 Programme) support for the conversion demonstration.

• Investment decision: Q4 2023.
• Forecast commissioning date: 2027.

• Length: ~90 km.
• Maximum capacity: 5.5 GWh/day.

According to an initial assessment, this project could contribute to averting 0.7 Mt CO₂eq/year in emissions in key industrial sectors.
