Welcome to the beginning of a clean new industrial era.
Powered by Coolbrook RotoDynamic Technology.
Electric high-temperature process heat for cement, iron and steel, aluminum and petrochemicals.
What we do
Coolbrook’s patented RotoDynamic Technology replaces fossil-fuel combustion in the hottest steps of industrial production with clean electricity. At full deployment it can cut up to 2.4 Gt of CO₂ a year – about 7% of global emissions.
RotoDynamic Heater™ (RDH) – Commercially available today and first unit in delivery. Designed for outlet temperatures up to 1,700 °C and demonstrated above 1,000 °C at MW scale over more than 5,000 pilot operating hours. Electric heat for kilns, furnaces, dryers and preheaters.
RotoDynamic Reactor™ (RDR) – In pilot stage and commercial launch targeted from 2029. Electric steam cracking that removes fuel-combustion CO₂ from olefin production when powered by renewable electricity, with up to 10% increase in ethylene and propylene yield.
Why electrify
Coolbrook’s RotoDynamic Technology electrifies industrial processes that have long been considered almost impossible to electrify. RDH is designed for up to 1,700 °C and has already run above 1,000 °C at MW scale – hard-to-abate becomes possible-to-abate.
Electrification of heavy industrial processes across hard-to-abate sectors is the key to achieving the required emission reductions and to speeding up the transition to net zero.
For most high-temperature heating duties, direct electrification with clean electricity is the most energy- and cost-efficient route to zero-carbon production.
How it works
From clean electricity to low-carbon products
01 Clean electricity
Renewable energy FROM WIND, solar and hydro replaces fossil fuels.
02 RotoDynamic heating
Renewable energy powers the RotoDynamic Technology with potential to heat up to 1,700 °C.
03 Low-carbon products
The products and materials produced with coolbrook technology carry a substantially lighter CO2 footprint.
For industries
Electrifying the hard-to-abate industries
Cement, steel, aluminum and petrochemical plants burn fossil fuels to reach the temperatures their processes need – a large share of their CO₂ emissions. RDH replaces that combustion with clean electricity in dryers, kilns, calciners, furnaces and pre-heaters. RDR does the same for steam cracking. Choose your industry to see where it fits in your process.

Built with industry leaders
We work with world’s leading industrial producers, technology companies and academic partners to develop RotoDynamic Technology and bring it to industrial scale quickly and broadly.
Our partner customers include Ambuja Cements (part of Adani Group), our first commercial customer, together with CEMEX, UltraTech Cement, , JSW Group, ArcelorMittal, Shell, Braskem, and SABIC.
Our technology and manufacturing partners are include ABB, Linde Engineering, Schmidtsche Schack, Tenova, Doncasters, Trac Precision Solutions and Turbostream.
We also partner with world leading universities, including Ghent University, University of Oxford, University of Cambridge.
We also work with Netherlands Enterprise Agency, Business Finland, Climate Leadership Coalition CLC and Brightlands Chemelot Campus.
We share the sense of urgency with our partners and customers for cutting CO2 emissions across various industries and believe that together we can create the positive change the world needs.
From pilot to delivery
From MW-scale pilot to first commercial delivery
Since December 2022 we have run RDH and RDR at our pilot plant at Brightlands Chemelot Campus in Geleen, the Netherlands: more than 5,000 operating hours, temperatures above 1,000 °C, and naphtha, hexane and pyrolysis oil cracked. Our first commercial project is in delivery, and the next generation of RDH is in development.
