Adani Cement Adopts Coolbrook RDH to Cut Carbon Emissions

In a groundbreaking step for industrial decarbonization, Adani Cement and Coolbrook have signed a delivery agreement for the world’s first commercial deployment of the RotoDynamic Heater (RDH) technology at the Boyareddypalli Integrated Cement Plant in Andhra Pradesh, India. This milestone marks the first-ever industrial-scale use of Coolbrook’s RDH system and a decisive stride toward Adani Cement’s net-zero goals by 2050, validated by the Science Based Targets initiative (SBTi).

This technology will also decarbonize the calcification process, which is the most fossil fuel intensive part of the cement-making process as it will provide clean heat to boost the heating value of other fuels. It allows a much greater replacement of fossil fuels with greener ones and reduces the annual CO2 emissions directly by approximately 60,000 tonnes, with the possibility of reducing by tenfold with higher deployment.

According to the announcement, “This technology will decarbonise 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.”

More importantly, the RDH system will become fully powered by the large-scale portfolio of renewable energy owned by Adani Cement, which will take care that the industrial heat generation is completely emission-free. This initiative also shows that it is a viable business idea in practice to have clean electrified industrial heat that is fully run on renewables.

Through this implementation, Adani Cement will be at the forefront of making India a global leader in the production of clean cement, and this will build the industrial revolution of this country to achieve a sustainable and carbon-neutral future.
