Iron Age 2.0 · Technology Solutions Since 1810

Fe-Forging
the World

Decarbonizing the backbone of civilization through iron-based green hydrogen and energy storage technologies.

"For us, taking responsibility means taking socially relevant issues into account in corporate decision-making processes, keeping an eye on what is happening beyond one's own area of competence, and looking at company-related activities from an ecological, social and ethical point of view." Stephan Koehne – CEO, TS Group

Core Innovation

3 Iron Core Technologies

TS Group develops a closed-loop iron energy ecosystem — from electrolysis to green steel — using iron as the central carbon-neutral energy carrier.

⚡

Iron Oxide Electrolyser (IOEC)

Electrochemical reduction of LiFeO₂ at ~500 °C, followed by hydrogen production via the Iron-Steam reaction. Higher efficiency than PEMEC/AEC, lower temperature than SOEC.

Electrolysis

💧

Iron Water–Hydrogen Converter

Reversible oxidation and reduction of iron using steam. Iron stores energy; adding water releases pure hydrogen on demand — a fully circular, low-cost energy carrier.

H₂ Storage

🏭

Iron Ore Powder Reduction

Direct Reduction of Iron (DRI) at 5,000 kg/h using green hydrogen — enabling carbon-free steel production and large-scale iron energy storage from renewables.

Technology 1

Iron Oxide
Electrolyser

The IOEC uses a lithium iron oxide salt electrolyte — not corrosive acid or base — at approximately 500 °C, combining electrochemical reduction and steam-iron hydrogen production in a single system.

Salt electrolyte — minimal corrosion, long service life
Operating temperature in the steam range — no exotic seals
Higher efficiency than PEMEC & AEC
Lower operating temperature than SOEC
No platinum-group metals or rare-earth materials
Simple, scalable production process

Technology 2

Iron Water–Hydrogen Converter

The converter system uses iron as a rechargeable hydrogen battery. Iron powder is oxidized with steam to release H₂; the resulting iron oxide is then reduced back to iron using green hydrogen — completing the cycle.

Live Project · First of its Kind

Green Steel
