Salzgitter SALCOS hot strip: Hydrogen-ready low-CO2 steel for automotive and engineering supply chains

Salzgitter's SALCOS hot strip is a low-carbon flat steel product made with hydrogen-based direct reduction and electric arc furnaces instead of blast furnaces. The company targets up to 95 percent lower CO2 intensity compared to its historical baseline. The product is designed as a drop-in replacement for conventional hot-rolled coil in automotive, machinery, and energy applications. A seven-year green hydrogen supply deal with EWE for around 10,000 tonnes per year from 2030 supports the production route. Salzgitter is also testing new green pellet technology to secure DR-grade iron ore inputs. The company provides batch-level carbon footprint documentation to help buyers meet CBAM and Scope 3 reporting requirements. SALCOS hot strip is a core part of Salzgitter's broader transformation program and competes with similar hydrogen-based steel projects in Europe. Volume growth depends on project execution, hydrogen infrastructure buildout, and customer willingness to pay a premium for certified CO2 reductions. The product is already available for specification in standard flat steel grades.

Good to see a concrete product rather than just press releases about hydrogen steel. The 95% CO2 reduction claim needs to be backed by audited data though. Anyone know if they publish the methodology?

The 10,000 tonnes of green hydrogen per year from 2030 is not a huge volume. For a steel plant that size, that covers maybe a fraction of total demand. Would be useful to know what stage of the SALCOS roadmap this supports.

The drop-in replacement angle is key for adoption. Auto makers don't want to requalify a whole new material grade. If it fits existing spec sheets, the barrier to switching is lower.

Batch-level carbon documentation is smart. CBAM and Scope 3 reporting are going to make that a requirement for any supplier selling into EU markets. This could become a competitive advantage if they execute well.

What is the actual price premium vs conventional hot rolled coil? Without that number, it's hard to gauge whether this is a real product or a marketing demo.
