ThyssenKrupp is Germany's largest steel producer and a diversified industrial conglomerate — combining Steel Europe (flat carbon steel), Industrial Components (automotive bearings, springs, chassis), Marine Systems (naval submarines and frigates) and Nucera (hydrogen electrolysers). After years of restructuring, ThyssenKrupp's steel division faces an existential transformation challenge — becoming the world's first large-scale green steel producer using hydrogen-based DRI-EAF technology.
Steel Europe: The Restructuring Challenge
ThyssenKrupp Steel Europe — producing approximately 11 million tonnes of flat steel for automotive, packaging and mechanical engineering — faces structural challenges: Chinese overcapacity eroding pricing, German automotive sector transformation reducing premium steel demand, and the massive capital requirement for green steel conversion. A partial stake sale of Steel Europe (with EP Corporate Group as potential partner) aims to bring in capital and management focus.
Green Steel Transformation: tkH2Steel
ThyssenKrupp's flagship transformation project — tkH2Steel — converts the Duisburg steelworks from blast furnace to hydrogen-based direct reduction iron. The first DRI-EAF unit (producing 2.5 million tonnes of green steel) requires €3B+ investment and depends on cheap renewable hydrogen availability. Success would make ThyssenKrupp the world's largest green steel producer. Failure would leave the company with an uncompetitive legacy asset.
Nucera: The Hydrogen Electrolyser Growth Story
ThyssenKrupp Nucera — separately listed on the Frankfurt exchange — produces alkaline water electrolysers for green hydrogen production. Nucera's 20 MW and larger electrolysis systems serve the emerging green hydrogen market for steel decarbonisation, ammonia production and fuel. Nucera's order backlog and revenue growth reflect early-stage green hydrogen infrastructure investment. ThyssenKrupp retains approximately 67% of Nucera.
Marine Systems: The Defence Beneficiary
ThyssenKrupp Marine Systems (TKMS) builds conventional submarines (Type 212A, Type 214) and frigates for the German Bundesmarine and export customers (Norway, Greece, Israel, Singapore). NATO defence spending increases — particularly submarine procurement by Norway, Netherlands and other allies — are generating significant TKMS order growth. Defence revenues provide earnings stability independent of the steel cycle.
Key Risks
Steel Europe restructuring is uncertain — the stake sale process has stalled multiple times. Hydrogen availability for tkH2Steel is not guaranteed — cheap renewable hydrogen at the scale required may not materialise by 2030. ThyssenKrupp's multi-year losses have eroded equity and management credibility. German automotive sector weakness — ThyssenKrupp's largest steel customer — is structural and accelerating.
