Salzgitter Mannesmann Forschung GmbH (SZMF), centralized research and development (R&D) company of the Salzgitter Group, is responsible for the overall project coordination and the full Life Cycle Assessment of the Steam Electrolyser.

Salzgitter Flachstahl GmbH (SZFG), site owner and operator of the iron-and-steel works, prepares the installation site, integrates the StE system into the existing infrastructure and is responsible for the operation and production of “green hydrogen”.

Sunfire GmbH (SF), the developer and provider of the steam electrolyser from their European manufacturing including installation, operation and maintenance.

Paul Wurth S.A. (PW), developer and provider of gas processing technologies will be responsible for the design and development of the HPU, which ensures the required hydrogen quality in terms of pressure and moisture. Additionally, PW will perform cost analysis to optimize service and maintenance strategy in order to achieve lowest life cycle cost. PW will further investigate routes for N2 cleaning for applications with higher H2 purity demands (5.0 qualities) or in case that the hydrogen quality of the electrolyser is not sufficient.

Tenova (TENOVA), a developer of innovative technologies and services for the metal and mining industries will create a study on the CO2 avoidance potential of hydrogen in the European steel industry. With its ENERGIRON-ZR process, a direct reduction process (DR) able to use alternative reducing gases such as hydrogen on a large scale, represents the leading edge of gas-based reduction technologies and an ideal step into the upcoming hydrogen era.

Commissariat à l’énergie atomique et aux énergies alternatives (CEA), as a key player in research, development and innovation will provide long term stack tests as well as energy management strategy assessment as a support to StE design and on-site operation, and techno-economic analysis as a basis for further market development.
