What TS Group does
TS Group is a privately held German technology company headquartered in Aachen that has rebuilt its identity around an iron-based green hydrogen and energy storage platform. Its business centers on three integrated proprietary technologies: the Iron Oxide Electrolyser (IOEC), which performs electrochemical reduction of lithium iron oxide at approximately 500°C followed by steam-iron hydrogen production in a single system; the Iron Water–Hydrogen Converter, which reversibly oxidizes and reduces iron using steam to release on-demand hydrogen from stored energy; and Iron Ore Powder Reduction (DRI), which uses green hydrogen to produce iron at a stated rate of 5,000 kg/h for carbon-free steelmaking. The platform is positioned as a closed-loop alternative to PEMEC, AEC, and SOEC electrolyzers, eliminating platinum-group metals, rare-earth materials, and corrosive acid/base electrolytes.
The company serves heavy-industry and energy-sector customers seeking decarbonization of iron, steel, and energy-intensive processes, with primary use cases spanning green hydrogen production, large-scale renewable energy storage, and green steel manufacturing. A specifically referenced "Namibia" project on its website indicates initial geographic expansion into Africa, leveraging proximity to iron-ore resources. Operating under CEO Stephan Koehne, the company traces its institutional history to 1810 and maintains an active website describing its technologies, although it discloses no financials, pricing models, partnerships, or named customers.
Revenue mechanics are not publicly disclosed; the source material contains no pricing information, customer logos, contract values, or unit-shipment data. With a stated headcount of 101–250 employees and operations spanning hardware development and at least one African project, TS Group appears to sit between pilot demonstration and early commercial deployment. Its go-to-market motion, distribution channels, marketing channels, and partnership network are not disclosed in the available data, leaving the commercial translation of its technology platform unverified by third-party evidence in this dataset.

TS Group product offering
Product offeringCore offering
TS Group designs and manufactures industrial-scale equipment for an iron-based closed-loop energy ecosystem. Its product portfolio comprises the Iron Oxide Electrolyser (IOEC) for green hydrogen production, the Iron Water–Hydrogen Converter for reversible iron-based energy storage, and an Iron Ore Powder Reduction (DRI) system for carbon-free green steel production using green hydrogen.
Product overview
TS Group develops a closed-loop iron energy ecosystem using iron as a central carbon-neutral energy carrier. The portfolio consists of three integrated core technologies: the Iron Oxide Electrolyser (IOEC) for electrochemical hydrogen production, the Iron Water–Hydrogen Converter for reversible energy storage via iron oxidation/reduction, and the Iron Ore Powder Reduction (DRI) system for green steel production. Together, these technologies form an integrated iron-based energy platform that enables decarbonization across hydrogen production, energy storage, and industrial steel manufacturing.

Products and services
- Iron Oxide Electrolyser (IOEC) Industrial electrochemical hydrogen production system using a lithium iron oxide salt electrolyte at approximately 500°C, combining electrochemical reduction and steam-iron hydrogen production in a single integrated system. Designed for heavy-industry buyers pursuing green hydrogen, with claimed higher efficiency than PEMEC/AEC electrolyzers and lower operating temperature than SOEC.
- Iron Water–Hydrogen Converter Industrial system for reversible oxidation and reduction of iron using steam; iron stores energy and adding water releases pure hydrogen on demand. Functions as a fully circular, low-cost hydrogen energy carrier for large-scale energy storage from renewables.
- Iron Ore Powder Reduction (DRI) Direct Reduction of Iron system operating at 5,000 kg/h using green hydrogen, enabling carbon-free green steel production and large-scale iron-energy storage from renewable electricity for steel manufacturers and heavy-industry operators.

TS Group competitors and assessment
Company assessmentDirect peers
- SSAB (HYBRIT initiative): Swedish steelmaker developing hydrogen-based DRI through the HYBRIT joint venture with LKAB and Vattenfall. Most directly comparable peer for TS Group's DRI module and the broader hydrogen-DRI green steel proposition.
- ITM Power: UK-based PEM electrolyzer specialist supplying large-scale green hydrogen plants. Directly comparable to TS Group's electrolyzer product line and serves similar heavy-industry and utility customers.
- Sunfire: German high-temperature SOEC electrolyzer company producing green hydrogen and e-fuels. Comparable as a German-headquartered electrolyzer competitor explicitly referenced in TS Group's own positioning ("lower temperature than SOEC").
- Nel ASA: Norwegian PEM and alkaline electrolyzer manufacturer and one of the most capitalized pure-play hydrogen equipment vendors. Directly comparable to TS Group's IOEC on the hydrogen production side, though Nel lacks iron-based storage and DRI.
- thyssenkrupp nucera: German alkaline and SOEC electrolyzer supplier spun out of thyssenkrupp, with deep integration into European steel and chemicals customers. Comparable electrolyzer portfolio and overlaps with TS Group's green steel value proposition.
Emerging players
- Stegra (formerly H2 Green Steel): Swedish greenfield green steel venture using green hydrogen DRI-EAF. Overlaps with TS Group's DRI focus but is integrated downstream into finished steel rather than selling the DRI module as equipment.
- Boston Metal: US-based molten oxide electrolysis company producing green steel from iron ore, with a technology approach broadly analogous to TS Group's molten-salt iron-oxide electrochemistry. Highly relevant as a competing route to carbon-free primary steelmaking.
Broad incumbents
- Plug Power: US-listed hydrogen platform spanning electrolyzers, fuel cells, and storage. Broad incumbent in green hydrogen with overlapping end-markets in heavy industry and energy storage, though operating from a different technology base.
- voestalpine: Austrian integrated steelmaker operating the world's first industrial-scale hydrogen DRI pilot (H2FUTURE). Comparable as a potential customer/partner for TS Group's DRI technology and a benchmark for hydrogen steel decarbonization scale-up.
- Cummins Accelera: Cummins' zero-emissions platform including PEM electrolyzers and hydrogen fuel cell systems. Comparable as a broad hydrogen incumbent competing across TS Group's target applications.
