Saarland mills, French companies combine hydrogen projects

Six companies, including German mills Dillinger and Saarstahl, have joined up to develop a green hydrogen economy in the border region of Saarland, France and Luxembourg, Kallanish learns.

The cooperation also involves energy company STEAG, plant manufacturer Siemens Energy, grid operator Creos Deutschland, and public transport company Saarbahn.

The partners are combining their respective hydrogen projects – “HydroHub Fenne” (STEAG), “H2SYNgas” (mills) and “TraficHdeux” (Saarbahn) in the Saarland, and the Saarland-French hydrogen project “mosaHYc” (Creos Deutschland). In response to a call from the German Federal Ministry for Economic Affairs and Energy they have applied for funding as an “Important Project of Common European Interest” (IPCEI).

Within the scope of H2SYNgas, Dillinger and Saarstahl are developing technology at a blast furnace at their joint pig iron plant, Rogesa, using the company’s own process gases together with hydrogen.

The mosaHYc project, jointly undertaken by the distribution grid operators Creos and GRTgaz, aims to use existing gas infrastructure to develop a cross-border high-pressure grid for the transport of hydrogen.

The HydroHub Fenne project by STEAG and Siemens Energy is to be the first PEM (proton exchange membrane) electrolysis plant of significant scale.

TraficHdeux aims to build up the infrastructure for operating cross-border public transport with hydrogen-powered fuel cell trains and buses.
