Adani Cement, Coolbrook to deploy world’s 1st industrial-scale RDH tech in Andhra to drive decarbonisation

Building materials solutions business of the diversified Adani Group, Adani Cement and transformational technology and engineering company Coolbrook have announced their delivery agreement for the world’s first commercial deployment of the RotoDynamic Heater (RDH) technology to advance cement decarbonisation at the Boyareddypalli Integrated Cement Plant in Andhra Pradesh, India. 

This marks the first industrial-scale deployment of Coolbrook’s RDH technology, which will help advance Adani Cement’s net-zero goals by 2050. Also, it will help Coolbrook’s goal of cutting 2.4 billion tonnes of annual CO₂ across heavy industry sectors globally.

What Coolbrook’s RDH technology does 

The technology decarbonises the calcination phase -- the most fossil fuel-intensive stage of cement production. By providing clean heat to dry and enhance the heating value of alternative fuels, the technology enables a significantly higher substitution of fossil fuels with sustainable alternatives. 

This deployment is expected to directly reduce 60,000 tonnes of carbon emissions annually, with a potential to increase 10x in due course, marking a major step toward decarbonising cement manufacturing. "Critically, the RDH system will be powered by Adani Cement’s large-scale renewable energy portfolio, ensuring that the industrial heat generated is completely emission-free," Adani Cement said in a statement. 

Vinod Bahety, CEO - Cement Business, Adani Group, called it a major leap towards achieving our net-zero goals. "By integrating such cutting-edge electrification solutions into our cement production, we are accelerating the shift away from fossil fuels, reducing emissions at scale, enhancing the utilisation of clean energy sources, and setting a new standard for low-carbon cement manufacturing."

Strong and scalable use-case

The Adani Cement believes that this project will provide a strong and scalable use case for deep industrial decarbonisation with significant potential for replication. "Coolbrook and Adani Cement have identified multiple follow-on opportunities for deploying RotoDynamic Technology across Adani Cement’s industrial operations and share an ambition to launch at least five additional projects within the next two years."

This technology will play a key role in decarbonising Adani Cement’s production, improving process efficiency, and accelerating its sustainability goals, including improving AFR (alternative fuels and resource materials) usage towards 30% and increasing the share of green power to 60% by FY28. 

The firstgen RDH will deliver hot gases at around 1000°C, which will facilitate drying of alternate fuels, making its utilisation greener and more efficient. “Entering into the first industrial-scale project in the world with Adani Cement marks a transformative step for industrial electrification in one of the world’s most vital cement markets,” said Joonas Rauramo, CEO of Coolbrook.
