Leading decarbonization solution for the most polluting industrial processes


Clean industrial electrification: A leap in decarbonization technology

Our game-changing RotoDynamic HeaterTM (RDH) and RotoDynamic ReactorTM (RDR) are the only solutions for electrifying and decarbonizing the traditionally hard-to-abate, most CO2-heavy high-temperature industrial processes, including the production of steel, iron, cement, and chemicals and petrochemicals.

Chemicals and petrochemicals, iron and steel, and cement industry account for over 50% of industrial energy use and for 2/3 of industrial CO2 emissions. Coolbrook’s decarbonization technology has the potential to cut industrial CO2 emissions with up to 30%, %, making it a key decarbonization solution for these industries.

Pilot to test RotoDynamic decarbonization technology

The only electrification technology capable of reducing total industrial CO2 emissions by over 2 Gt or 30%

RotoDynamic Technology is the only electric technology capable of reducing total industrial CO2 emissions by up to 2.4 Gt or 30% – accounting for an annual reduction of 7% in total global CO2 emissions.

We have teamed up with the world’s leading electrification technology partners and industrial customers to roll-out the decarbonization technology at scale by the mid 2020’s.

Hard-to-abate is now possible-to-abate

Decarbonization technology for heavy industry

It’s long been thought that industrial processes like the production of steel, iron, cement and petrochemicals, and other chemicals are difficult – if not impossible – to decarbonise. Our RotoDynamic decarbonization technology is the only electric solution in the world capable of cutting up to 30% – or 2.4 billion tons – of global industrial CO2 emissions annually.

Decarbonization of cement industry

Cement industry decarbonization

Our technology can cut 1,000 million tons of CO2 in cement production per year globally.

RotoDynamic Technology can be used for example in pre-heating for clinker production and replacing existing fossil-fired kilns with heating by RotoDynamic Heater.

Decarbonization of petrochemical industry

Chemical and petrochemical industry decarbonization

RotoDynamic Reactor cuts 100% of CO2 emissions from steam cracking through electrification.

The technology is also suitable for H2 and methanol production from natural gas or biogas. Together, RotoDynamic Heater and RotoDynamic Reactor technologies can cut 500 Mt of CO2 emissions globally in chemicals and petrochemicals industry.

Iron and steel industry decarbonization

Steel and iron industry decarbonization

In iron and steel industries, RotoDynamic Technology can cut 600 Mt of global CO2 emissions annually.

Use cases for the RotoDynamic Heater range from pre-heating of air to blast furnace, provisioning of heat for H2 based reduction process to heating for hot rolling and casting, coking, sintering.

Decarbonization solutions for industrial processes

Other industries

Our technology can cut 300 Mt of CO2 in other industries, with use cases in e.g. melting of glass, heating for aluminium oxide production, end of life treatment of waste and residues, and more.

Timeline to production

Ready for commercial launch at scale in 2025

We’re partnering with some of the brightest minds and biggest industrial players in the world to make our RotoDynamic Technology the new global standard in the electrification of traditionally highly polluting industrial production processes. While engaging with our partners and customers and ramping up our organization, we are also demonstrating the technology and its capabilities at our pilot plant in Geleen, the Netherlands, since December 2022.

2021 – 2023

  • Demonstrate RotoDynamic technology and engage customers in petrochemicals and other key industrial sectors
  • Partnering with industrial actors, EPC partners and universities for successful piloting
  • Ramp-up of organization

2022 – 2024

  • Commercial scale units installed at customer sites:
    • RDR connected to ethylene plant
    • RDH in selected applications (e.g. steel industry and cement industry)
  • Engage technology suppliers to include RDR and RDH in their offering
  • Network of partners to secure successful commercial launch
  • Strengthen organization and validate key assumptions for commercial launch

2024 →

  • Commercial deliveries to customers
  • RDR and RDH part of technology offering of key suppliers and EPC companies
  • World class organization and capabilities to deliver value for all stakeholders
  • Continued value-adding partnerships within network of globally leading industry players and decarbonization actors in different sectors

RotoDynamic Technology is being pilot tested at a large-scale testing unit at Brightlands Chemelot Campus in Geleen, the Netherlands.

The main targets of the pilot project:

  • Demonstrate the use of RotoDynamic HeaterTM (RDH) technology for high-temperature process heating with inert gases, such as: air, nitrogen, methane, steam, CO2
  • Demonstrate the RotoDynamic ReactorTM (RDR) technology and its reliability for hydrocarbon cracking to stakeholders in the petrochemical industry
  • Validate modelling (fluid dynamics) and design parameters and to establish basis for first customer projects

The first phase of the pilot tests was successfully completed in September 2023. The test phase demonstrated RDH technology’s capabilities for industrial use in high-temperature process heating, enabling the technology to move forward to industrial scale projects at customer sites.

In late 2023, Coolbrook has successfully cracked naphtha with the RotoDynamic Reactor, demonstrating electric steam cracking of naphtha and validating the potential of Coolbrook’s RDR Technology to replace traditional fossil fuel-based cracker furnaces with electric RDR units in the petrochemical industry.

Learn more about the end-results that demonstrate this electrification solution’s potential to reduce global industrial CO2 emissions in gigaton scale.

Coolbrook has built a comprehensive partnership ecosystem consisting of leading technology and industrial partners, as well as academic institutions, to develop and launch the technology. Read more about the decarbonization partnerships and how you can participate.

A comprehensive and growing partner ecosystem

We are already partnering with some of the world’s leading industrial producers, technology companies and academic partners in development of our decarbonization technology and to ensure fast and broad adoption of our technology for industrial electrification.

Our partners and customers include ABB, Linde Engineering, Schmidtsche Schack, Shell, Braskem, SABIC, CEMEX, UltraTech Cement, ArcelorMittal, as well as Ghent University, University of Oxford, University of Cambridge.
