The partnership will initially integrate Coolbrook’s RDH technology with Tenova’s solutions for acid regeneration plants, with plans to expand to other applications in the metals sector. The companies state that their combined expertise supports electrification and reduces carbon emissions in metal production processes.
Antonio Catalano, Executive Vice President for Tenova’s Downstream Business Unit, said: “Our collaboration with Coolbrook marks a key milestone in decarbonising high-temperature industrial processes…By replacing fossil fuels with renewable electricity, we can dramatically reduce CO₂ emissions but also achieve a significant step in process efficiency – making production cleaner, faster, and more cost-effective.”
Coolbrook’s CEO, Joonas Rauramo, commented: “Our partnership with Tenova is a significant step in advancing industrial electrification and accelerating the transition to clean energy. By integrating our RDH technology with Tenova’s innovative solutions, we can develop joint offerings to decarbonise highly challenging applications that have previously been impossible to electrify.” He added that such collaborations enable them to “deliver broader, more sophisticated solutions to our customers than either company could achieve independently.”
Coolbrook’s RDH technology is designed to reduce over 2.4 billion tons of CO₂ emissions annually when widely implemented. Large-scale pilot tests have demonstrated the technology’s ability to generate heat above 1,000°C, reaching up to 1,700°C, suitable for decarbonizing high-temperature industrial processes.
The RDH technology originated from a concept by rocket scientists addressing coking issues in petrochemical steam cracking plants. This led to the development of turbomachinery capable of heating various gases for multiple applications, operating at temperatures above 700°C and power levels from 5-10 MW to 1,700°C and tens or hundreds of MW.
Coolbrook and Tenova are working with industry partners to understand sector needs and develop phased investment options to lower initial capital costs for industrial clients. This partnership reflects a shared commitment to advancing sustainable practices in the metals industry through innovative technology.
