India Hosts World’s 1st Commercial Deployment of Coolbrook’s RotoDynamic Heater™ at Adani Cement Plant

• Adani Cement’s Boyareddypalli plant in Andhra Pradesh will be the first cement plant globally to commercially deploy Coolbrook’s RotoDynamic Heater™ (RDH™) technology in the industrial space.
• RDH™ system will be powered entirely by Adani Cement’s large-scale renewable energy portfolio, ensuring that the industrial heat generated is completely carbon emission free.
• This commercial deployment is expected to directly reduce ~60,000 tonnes of CO₂ emissions annually with a potential to increase 10x in due course.
• Complements Adani Cement’s targets to increase AFR to 30% (upped from earlier target of 28%) while we achieve 60% green power share by FY28.

Adani Cement and Coolbrook announce their delivery agreement for the world’s first commercial deployment of the revolutionary 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, advancing Adani Cement’s net-zero goals achievement by 2050 (validated by the SBTi) and Coolbrook’s goal of cutting 2.4 billion tonnes of annual CO₂ across heavy industry sectors globally.

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. 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 entirely by Adani Cement’s large-scale renewable energy portfolio, ensuring that the industrial heat generated is completely emission free. This deployment demonstrates the real-world feasibility of clean, electrified industrial heat powered entirely by renewables. This positions Adani Cement to spearhead India’s emergence as the world’s clean manufacturing cement hub.

Mr Vinod Bahety, CEO - Cement Business, Adani Group, said: “The world’s first commercial deployment of Coolbrook’s RotoDynamic Heater™ within our operations marks a pivotal moment in our decarbonisation journey. This is 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. This ongoing partnership reflects our unwavering commitment to climate leadership and delivering long-term value through innovation and sustainability. This milestone underscores our legacy as pioneers and highlights our transformative actions towards becoming a global building materials solutions powerhouse. We are building a stronger eco-system of partners like Coolbrook along with our R&D investments.”

The project provides 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.

Going forward, RDH™ technology will play a pivotal role in decarbonising Adani Cement’s production, improve process efficiency, and accelerate the Company’s 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 first generation RDH™ will deliver hot gases at around 1000°C, which will facilitate drying of alternate fuels, making its utilisation greener and more efficient, representing a breakthrough in high-temperature electrification for cement production.

“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 Mr Joonas Rauramo, CEO of Coolbrook. “Our mission is to make RotoDynamic Technology a new industry standard for decarbonising hard-to-abate sectors. Together, we’re redefining how cement is produced - cleaner, more efficient, and ready for a net-zero future.”

Adani Cement’s broader sustainability leadership is reflected in it being among the four large-scale cement companies globally to have SBTi-validated net-zero targets and global collaborations including being the world’s first cement manufacturer to join the Alliance for Industry Decarbonisation (AFID), under IRENA.

Adani Group May Soon Acquire Jaypee Cement and Its Assets

The Adani Group is actively exploring cement acquisitions, with a focus on surpassing Aditya Birla Group's UltraTech to become India's largest cement manufacturer. Adani Group has earmarked $3 billion for this purpose. Specifically, they are in talks to buy the cement businesses of debt-laden Jaypee Group for about ₹5,000 crore.

The potential acquisition targets include Hyderabad-based Penna Cement, Gujarat-headquartered Saurashtra Cement, and the cement business of Jaiprakash Associates. This move comes as lenders initiated insolvency and bankruptcy proceedings (IBC) against Jaiprakash Associates Ltd (JAL) in early June.

The annual capacity of Jaypee cement is more than 90 lakh tonnes, according to Moneycontrol, citing sources.

According to sources, as the proceedings against Jayaprakash begin, Adani Group has to acquire assets such as limestone mines and a power plant attached to the company's cement assets.

The formal process of selling assets of Jayaprakash Associates has not yet begun. Dalmia India signed a deal with Jaypee in 2022 to purchase its cement and power assets at an enterprise value of Rs 5,666 crore. However, since Jaypee Associates could not get approval from Lenders, the deal had not been completed.

The Jaypee Group, a conglomerate with interests in real estate, infrastructure, and cement, has faced significant financial challenges. As of now, they owe ₹30,000 crore to 32 creditors, including ICICI Bank. Recently, they were admitted to the National Company Law Tribunal (NCLT) after a six-year delay. The resolution plan by Suraksha Asset Reconstruction Limited (Suraksha ARC) aims to complete over 20,000 pending housing units in the national capital region, but potential litigation may further delay home buyers' dreams of owning their homes.
