Electrifying the world’s most polluting industrial processes


Replacing fossil fuels with clean industrial electrification

Our revolutionary RotoDynamic HeaterTM (RDH) and RotoDynamic ReactorTM (RDR) are the only solution for electrifying and decarbonizing the traditionally hard-to-abate, most CO2-heavy 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 technology has the potential to cut industrial CO2 emissions with up to 30%.

The only electric 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 technology partners and industrial customers to roll-out the technology at scale by the mid 2020’s.

Solution for decarbonisation

Heavy industry is no longer hard-to-abate

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 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.

Cement production

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.

Chemicals and petrochemicals

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.

Steel and iron production

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

Use cases 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.

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 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 and cement)
  • 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 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

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 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. We also partner with Netherlands Enterprise Agency, Business Finland, Climate Leadership Coalition CLC and Brightlands.

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.
