Coolbrook and Tenova join forces to drive CO2-free ​​Iron,​ Steel and Other Metals Production

Castellanza, April 16, 2025

Coolbrook, a transformational engineering and technology company focusing on industrial electrification, and Tenova, a leading provider of innovative and sustainable solutions for the metals and mining industries, have announced a strategic partnership on the development and deployment of Coolbrook’s proprietary RotoDynamic Heater™ (RDH™) technology. This will replace​ the​ burning of fossil fuels with clean electricity in high-temperature heating processes in the iron, steel, and broader metals industries.    

Coolbrook’s expertise in electrifying high-temperature industrial processes​ ​aligns with Tenova’s portfolio of innovative and sustainable solutions. Coolbrook’s RDH™ Technology and Tenova’s ​​expertise are particularly complementary to provide fully electrified and decarbonized processes ​across numerous applications in iron, steel, and other metals production that​ significantly reduce CO2 ​​emissions.  

The aim of the strategic partnership is to develop joint ​solutions​ that integrates Coolbrook and Tenova’s technologies, providing distinctive, seamless, and comprehensive ​offerings​ for industrial customers. The initial focus of the partnership will be the integration of Coolbrook’s RDH™ technology into Tenova’s proprietary technology for acid regeneration plants. ​Once completed, ​Tenova and Coolbrook are planning to expand the collaboration ​to​ other applications across the metals industry.  

Antonio Catalano, EVP for the Downstream BU at Tenova, said: “At Tenova, we are committed to driving the metals industries towards a more sustainable future. Our collaboration with Coolbrook marks a key milestone in decarbonizing high-temperature industrial processes by combining Coolbrook’s innovative RDH™ technology with our advanced solutions. 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. This is a powerful example of how technological innovation can accelerate both sustainability and operational excellence in our industry.”   

Joonas Rauramo, CEO of Coolbrook, said, “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 decarbonize highly challenging applications that have previously been impossible to electrify. Through this partnership, we are positioned to deliver broader, more sophisticated solutions to our customers than either company could achieve independently. Our partnership with Tenova is a key milestone in our strategy to establish a strong and collaborative ecosystem around Coolbrook’s RotoDynamic technology, ensuring its rapid industrial-scale adoption.“

Coolbrook’s RotoDynamic Heater™ Technology is a groundbreaking innovation that enables high-temperature industrial process heating using CO2-free electricity. As a key step toward carbon-free manufacturing, RDH™ Technology has the potential to revolutionize heavy industries by significantly reducing reliance on fossil fuels. When deployed at scale, it could cut over 2.4 billion tons of CO₂ emissions annually, making a transformative impact on industrial decarbonization. Large-scale pilot tests have proven its heat-generating capabilities beyond 1000 °C, with the technology reaching up to 1700 °C, a crucial breakthrough for decarbonizing high-temperature industrial processes.   

Coolbrook aims to establish the RDH™ technology as an industry standard by 2030.  

About Coolbrook  

Hailed as the key technology for industrial decarbonization globally, Coolbrook is a transformational technology and engineering company on a mission to decarbonize major industrial sectors like petrochemicals and chemicals, iron and steel, and cement. Coolbrook’s revolutionary rotating technology combines rocket science, turbomachinery, and chemical engineering to replace burning of fossil fuels across all major industrial sectors.  

The technology has two main applications: RotoDynamic Reactor™ (RDR™) to reach 100% CO2-free olefin production and RotoDynamic Heater™ (RDH™) to provide carbon-free process heating to iron and steel, cement, and chemicals production, among others. Once implemented at scale, the RotoDynamic Technology has the potential to reach temperatures up to 1700 °C and to cut over 2.4 billion tons (30%) of annual CO2 emissions in heavy industry.
