Piloting RotoDynamic Technology: Shaping the Future of Electrification

To develop our technology and broaden our partner network, we are operating a RotoDynamic Technology pilot plant   at the Brightlands Chemelot Campus in Geleen, the Netherlands, in the heart of the petrochemical industry.

Coolbrook pilot demonstrates the massive potential of the revolutionary new electrification technology to heavy industries, technology providers and policy makers.

Pilot: high-temperature heating electrification

RDH – RotoDynamic Heater – Electrification of high-temperature process heat in the production of cement, steel, iron and chemicals

RotoDynamic HeaterTM (RDHTM) is the only technology in the world able to reach high-temperature heat, up to 1700°C, powered by electricity and without burning fossil fuels. This enables it to replace fossil-fired furnaces and kilns with electrification of industrial processes. Learn more about our innovative approaches to decarbonize the hard-to-abate industries, like steel industry and cement industry.

In 2023, the successfully completed RotoDynamic Technology pilot’s first 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.

Targets of the RDH industrial process heating pilot

  • Validate modelling and design parameters for industrial process heating applications.
  • Demonstrate RDH applicability as a reliable source of industrial process heat.
  • Tests to be conducted with inert gases (air, steam and methane) and petrochemical feedstocks (naphtha, ethane, propane, butane).
  • First air tests with the reactor were conducted in 2021. Tests at the Pilot site, to be conducted for approximately 24 months, were started in December 2022.

Industrial heating pilot progress

  • In 2023, the successfully completed first test phase demonstrated RDH’s capabilities for industrial use in high-temperature process heating.
  • The testing exceeded the temperature of 1000°C, which is above the range of conventional resistive heaters by several hundred degrees. (Read the full press release about the successful pilot for industrial electrification and decarbonization of high-temperature industrial heating.)
  • The tests validated Coolbrook’s technical pathway up to 1700°C, covering more than 95% of the temperature range required to cover the EUR 1 trillion industrial heating market.

Pilot: electrification of steam cracking

RotoDynamic Reactor – electrification of steam cracking in production of petrochemicals

RotoDynamic ReactorTM (RDRTM), using electrification powered by renewable energy, is the only technology in the world capable of eliminating 100% of the CO2 emissions created in the steam cracking process, the first and most polluting step in the production of petrochemicals.

In 2023, Coolbrook successfully cracked naphtha in its large-scale pilot plant leading the way to zero-carbon steam cracking and validating the potential of the technology to replace traditional fossil fuel-based cracker furnaces with electric RDR units in the petrochemical industry. Read the full press release about successful electric cracking pilot.

Targets and progress of the RDR steam cracking pilot

  • Optimize the cracking process inside the reactor and validate modelling results.
  • Test yields and conversion with different feeds, understand the effect of RDR’s process conditions on coking.

Electric steam cracking pilot progress:

  • In 2023, successful cracking of naphtha and demonstration of electric steam cracking of naphtha.
  • Tests validated the potential of RotoDynamic ReactorTM (RDR) Technology to replace traditional fossil fuel-based cracker furnaces with electric RDR units in the petrochemical industry.

Timeline to production

Future of electrification – Ready for commercial launch at scale in 2025

This game-changing technology already exists today and a large and growing number of global industrial players and governments have expressed great interest in using it to cut CO2 emissions and meet crucial climate targets. Our RotoDynamic Heater and RotoDynamic Reactor technologies are currently being piloted. The electrification technology can be retrofitted to existing production plants and will be ready for large-scale use in 2024.

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

2023 – 2025

  • Commercial scale units installed at customer sites:
  • 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

Coolbrook has set out to build a committed and comprehensive ecosystem around RDR and RDH technology to commercialize it as soon as possible. Together with our partners in industry, academia, the public sector and key decision-makers, we can roll out this revolutionary technology and achieve significant emission reductions in the most energy and CO2 intensive industrial processes, which until now have been considered impossible to electrify.
