  • Coolbrook’s revolutionary RDH technology can replace burning of fossil fuels with electrification in cement production and reduce global industrial CO2 emissions by up to 30%
  • Coolbrook and India’s largest cement producer UltraTech Cement Limited sign a memorandum of understanding aiming to electrify cement production

Coolbrook, a transformational technology and engineering company, has today announced its co-operation with UltraTech Cement Limited to electrify the cement production process with Coolbrook’s patented Roto Dynamic Heater (RDH) technology. The RDH technology has been successfully piloted in Finland and is expected to be available for commercial use at scale in 2024.

Cement production is one of the most energy intensive and highest CO2 emitting industrial sectors. Cement production accounts for 30% of global industrial CO2 emissions and some 45% of those emissions originate from burning of fossil fuels in kilns. India is currently the second largest cement market globally with continuously growing production volumes.

Coolbrook’s RDH technology, powered by renewable electricity, can achieve process temperatures of up to around 1700 ºC with high energy efficiency and replace burning of fossil fuels in various parts of the cement production process. Ultimately Coolbrook aims to reach fully electrified cement production combined with carbon capture of the chemical process emissions to reach 100% CO2-free cement.

Ilpo Kuokkanen, Executive Chairman of Coolbrook, said: “India is one of the most important potential markets for Coolbrook as we want to make a global impact on CO2 emission reductions. Cooperation with India’s largest cement producer UltraTech is a significant step in our strategy to decarbonise heavy industry processes globally. UltraTech is also an excellent addition to our comprehensive and responsive partnership ecosystem spanning across leading industrial actors, academic institutions, and the public sector.”

Kailash Jhanwar, Managing Director of UltraTech Cement, said, “UltraTech is a forerunner in utilising renewable energy in its manufacturing operations. We are constantly looking at opportunities to improve process efficiency and reduce GHG emissions from our operations. Coolbrook’s RDH technology can be a real game changer in reducing CO2 emissions from cement production. We believe that our collaboration with Coolbrook will help to further accelerate the decarbonisation of our operations.”
