Coolbrook awarded €2.5m Business Finland grant to accelerate RDH electrification for steel

Key highlights
  • Coolbrook’s FutSteel scope totals €5.0m, with €2.5m provided as grant funding to Coolbrook.
  • Funding targets development and integration of the RotoDynamic Heater (RDH™) for high‑temperature steel applications up to 1700°C.
  • Planned RDH integration covers blast furnace processes, electrified reheating, hot‑stove air pre‑heating, hybrid heating, decarbonised DRI and hydrogen‑based steel production.
  • Coolbrook has previously deployed RDH technology commercially in cement with Ambuja Cement (Adani Group) and will collaborate with SSAB within the FutSteel ecosystem.

Funding and scope

Coolbrook has been awarded Business Finland R&D funding to support its participation in the FutSteel project led by SSAB. Coolbrook’s project scope within FutSteel is €5.0 million, of which €2.5 million is covered by the grant to Coolbrook.

Targeted steel applications

The work will accelerate development of Coolbrook’s RotoDynamic Heater (RDH™) for high‑temperature steel applications, focusing on integrating RDH into blast furnace processes, electrified reheating, hot‑stove air pre‑heating, hybrid‑heating concepts, decarbonised Direct Reduced Iron (DRI) production and hydrogen‑based steelmaking.

Technology and prior deployment

RDH™ uses renewable electricity to reach temperatures up to 1700°C with zero operational CO2 emissions. Coolbrook cites a prior commercial‑scale deployment of RDH in the cement sector with Ambuja Cement (Adani Group) as the engineering basis for scaling into steel.

Collaboration and objectives

The funding will support advanced process modelling, equipment development and IPR activities. SSAB and FutSteel partners will work with Coolbrook to accelerate industrial deployment, aligning with Business Finland’s goal of strengthening Finland’s competitiveness through exportable green technologies.
