Bringing the world together to kickstart a Clean New Industrial Era


Coolbrook – a team on a mission for industrial electrification

Join us in a new era of industrial decarbonization enabled by Coolbrook RotoDynamic Technology – industrial electrification powered by clean energy – will end the burning of fossil fuels in the most polluting part of industrial processes.

We are bringing our RotoDynamic Technology, industry and technology leaders, and world leaders together to solve the biggest challenge our world has ever faced – the urgent need to drastically reduce CO2 emissions. Together we can cut 30% of industrial CO2 emissions and 7% of total CO2 emissions annually.

About Coolbrook: Pioneers in Electrification Technology for Industrial Decarbonization

As a pioneering electrification technology and engineering company Coolbrook is committed to decarbonize major industrial sectors like chemical and petrochemical industries, iron and steel industries, and cement industry.

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.

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

Backed by a growing number of technology and industrial partners, Coolbrook’s technology is on a path to become the new global standard in industrial electrification.

By replacing fossil fuels with industrial 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, Coolbrook RotoDynamic Technology can cut more than 2 billion tons of CO2 emissions annually, helping to create a more sustainable future for us all.

Coolbrook team is bringing together world-class expertise across different fields – experts in rocket science, mechanical engineering, chemistry, and more.

Together we are developing the cleaner and more efficient industrial electrification solution that will drive the decarbonization of highly polluting sectors and our planet forward.

History of Coolbrook and RotoDynamic Technology

Coolbrook RotoDynamic Technology development started in late 1990’s when a group of rocket engineers worked on an idea of a turbine-like device for the generation of high temperature process heat in petrochemical production.

An early prototype device was introduced in 2011 to Finnish entrepreneur Ilpo Kuokkanen and the former long-time Coolbrook CEO Harri Johannesdahl. This led to establishment of Coolbrook company around the technology to develop it further with Oxford and Cambridge university laboratories in the UK and Neste Engineering in Finland.

Years of hard work with modelling, CFD calculations, patenting and introduction among the potential customers took place. As the urgency to fight against climate change became a priority in the political agenda together with favourable price development of renewable energy and the introduction of CO2 pricing, major industrial companies’ interest towards decarbonization and Coolbrook’s electric technology and its potential was really ignited.

From 2020 on, several major players in cement, petrochemicals and steel industries have signed up to be among the first producers to start applying Coolbrook’s revolutionary clean technology following the last large-scale pilot demonstration tests during 2023 at Brightlands Chemelot Campus, the Netherlands.

Coolbrook’s RotoDynamic technology is all set to start cutting 2.4 billion tonnes of CO2 emissions and kickstart a clean new industrial era.
