Bringing the World Together
to Kickstart a Clean New
Industrial Era

Join us to usher in a new era – where our novel RDR and RDH technology will replace 100% of the fossil fuels used in the most polluting part of industrial processes with electrification powered by clean energy. Together we we can cut 30% of industrial CO2 emissions and 7% of total CO2 emissions annually.

As a company, our vision is to bring our RDR & RDH technology, world leaders and industry leaders together to meet the biggest challenge our world has ever faced – the urgent need to drastically reduce CO2 emissions.

About Coolbrook

Coolbrook Ltd. is a transformational technology and engineering company on a mission to de-carbonize major industrial sectors like petrochemicals and chemicals, iron and steel, and cement.

Watch the video above about Coolbrook.

Coolbrook's revolutionary rotating technology combines space science, turbomachinery and chemical engineering to replace burning of fossil fuels across all major industrial sectors. The technology has two main applications: RotoDynamic Reactor (RDR) to reach 100% CO2 free olefin production, and RotoDynamic Heater (RDH) to provide carbon-free process heating to iron and steel, cement and chemicals production.

Backed by a growing number of governments, technology partners, industrial producers and environmental regulators, Coolbrook technology is set to become the new global standard in industrial electrification.

Bringing the world together to cut more than 30% of industrial CO2 emissions

Our RDR and RDH technology combines rocket science, turbomachinery and chemical engineering to turn some of the world's most polluting industrial processes into some of the cleanest. By replacing fossil fuels with electrification powered by clean and renewable energy, it's the only technology in the world capable of cutting 30% of industrial CO2 emissions and 7% of global CO2 emissions annually. But only if the world comes together to use it.

By joining forces with industrial and academic partners and world governments, our RDR and RDH technology can cut more than 2 billion tons of CO2 emissions annually, helping to create a more sustainable future for us all.
