German flat steel producer using its own plant as a live testbed for green hydrogen via solid oxide electrolysis, targeting steel industry decarbonization.
Salzgitter Flachstahl GmbH is one of Germany's major flat steel producers, manufacturing hot-rolled and cold-rolled steel strip for automotive, construction, and mechanical engineering markets. Within the EU research sphere, they have positioned themselves as an industrial testbed and end-user for green hydrogen technology — specifically exploring how high-temperature electrolysis can decarbonize the enormous energy demands of steel production. Their contribution to EU projects is as an industrial validation partner: they bring real steel plant infrastructure, process heat availability, and industrial-scale hydrogen consumption needs to research consortia. In practical terms, they represent the demand side of the hydrogen economy — a heavy industry player testing whether green hydrogen can replace fossil fuels in steelmaking at commercial scale.
Both GrInHy (2016) and GrInHy2.0 (2019) focused directly on generating green hydrogen through reversible high-temperature and steam electrolysis processes tested at steel plant scale.
GrInHy2.0 explicitly targets SOEC and steam electrolyser deployment, with Salzgitter providing the industrial site and process conditions for validation.
Both projects are framed around reducing the carbon footprint of steel manufacturing by substituting fossil-fuel-derived hydrogen with electrolysis-produced green hydrogen on-site.
Steel plants generate large volumes of high-temperature process heat; the GrInHy projects exploit this heat surplus to improve the efficiency of high-temperature electrolysis, a capability unique to integrated steelworks.
Salzgitter's H2020 trajectory is a focused, two-step deepening rather than a pivot. Their first project (GrInHy, 2016–2019) established the proof-of-concept for reversible high-temperature electrolysis in a real industrial steel plant — the emphasis was on feasibility and reversible operation. Their follow-on project (GrInHy2.0, 2019–2022) moved directly into scale-up and technology maturation, with the keyword set sharpening to specific hardware (steam electrolyser, SOEC) and explicit naming of the steel industry context. The trend is linear and deliberate: they are not exploring green hydrogen broadly, but systematically validating one specific technology pathway — SOEC-based steam electrolysis — for eventual deployment within their own production process.
Salzgitter is moving from research validation toward industrial deployment readiness for green hydrogen in steelmaking, making them a strong candidate for future IA-level or IPCEI projects on hydrogen-based direct reduction of iron (DRI).
Salzgitter participates exclusively as a consortium partner — they have never led an H2020 project — which reflects their role as an industrial host and end-user rather than a research coordinator. Their two projects are sequential continuations within the same FCH2 JU programme, suggesting they work in a stable, returning consortium rather than opportunistically joining unrelated calls. With 10 unique partners across 7 countries from just 2 projects, they operate in mid-sized, focused consortia typical of FCH2 Joint Undertaking grants where each partner brings a distinct, non-overlapping function.
Salzgitter has built connections with 10 distinct partners across 7 European countries through two tightly linked FCH2 projects, indicating a compact but internationally spread network centred on hydrogen and electrolyser technology. Their collaboration geography likely spans Germany, France, and other core EU industrial nations given the FCH2 JU consortium profile, though specific partner identities are not available in the data.
Salzgitter Flachstahl is rare among EU research participants because they are a large industrial steel producer, not a university or research institute — they bring a real, operating steel mill as the test environment, something no lab can replicate. This makes them uniquely valuable in any consortium that needs to demonstrate hydrogen technology at industrial scale rather than pilot scale. For any research group or technology supplier working on SOEC, hydrogen storage, or industrial decarbonisation, Salzgitter offers direct access to the single hardest-to-decarbonize industrial sector, with genuine commercial stakes in the outcome.
