RotoDynamic Electrification Solutions to decarbonize industrial processes

Our Technology

Rocket science and turbomachinery meet chemical engineering

Rocket science, turbomachinery and chemical engineering combined to electrify industrial processes

Coolbrook’s game-changing RotoDynamic Technology, a forefront electrification solution, combines the principles of rocket science, turbomachinery and chemical engineering. This revolutionary technology has the potential to reach temperatures of 1700 C degrees and it enables the electrification and decarbonization of high-temperature industrial processes which have been traditionally considered hard-to-abate. This marks a significant advancement in the field of industrial electrification technology.

The technology has two main applications: RotoDynamic HeaterTM (RDH) and RotoDynamic ReactorTM (RDR) which, once deployed at scale, have the potential to cut global industrial CO2 emissions by up to 2.4 Gt or 30%. This accounts for 7% of annual global CO2 emissions.

Coolbrook technology has the potential to be the most significant single technology to reduce industrial CO2 emissions globally.

The pilot test of our electrification technology at Brightlands Chemelot Campus in Geleen, the Netherlands

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

The main targets of the pilot testing:

  • Demonstrate the use of RotoDynamic HeaterTM (RDH) technology for high-temperature industrial 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.

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.

Direct electrification is the superior technology for decarbonizing

Everything that can be electrified, must be electrified

Electrification of industrial processes across industry sectors – including the ones hardest-to-abate – is key to achieving the required emission reductions and to speed up the transition to carbon-zero.

Clean electricity provides a clear pathway towards zero carbon industrial production in an energy and cost-efficient manner. Direct electrification is clearly the superior alternative in all applicable cases due to higher energy efficiency and lower cost.

Use case comparison to green hydrogen

Direct electrification is superior for decarbonizing heavy industries.

Cost: approximately 30-60% lower operating costs when using RotoDynamic Heater for process heating over green hydrogen in 20301.

Required infrastructure: widespread use of green hydrogen requires massive investments to H2 infrastructure and electricity networks.

Efficiency: 90% of electricity produced can be used for process heating vs 40-60% in burning of hydrogen.

1 With estimated green hydrogen cost of 2,700 USD / ton in 2030, electricity price 40 USD/MWh and direct electrification pays 10-30% premium for electricity compared to electrolysers
