Cement maker adopts thermal battery storage to slash fossil-fuel heat
Holcim, a major cement producer, is partnering with Boston-based Electrified Thermal Solutions to deploy thermal batteries that store clean electricity as heat for industrial processes. The technology aims to replace fossil-fuel burners used to generate the extreme temperatures required in cement manufacturing. This marks the first commercial-scale use of such batteries in the cement sector, potentially cutting significant carbon emissions from one of the hardest-to-decarbonize industries.
Holcim, a leading global cement manufacturer, has announced a collaboration with Electrified Thermal Solutions, a Boston-based startup. The partnership will deploy thermal battery systems that capture surplus clean electricity and store it as high-temperature heat. This heat is then used to power the kilns and other processes essential for cement production, replacing traditional fossil-fuel burners. This deployment represents the first commercial-scale application of such batteries within the cement industry.
The significance lies in cement's status as one of the most challenging sectors to decarbonize, largely due to its reliance on extreme heat. By shifting this heat source from fossil fuels to stored renewable energy, the technology could dramatically reduce the industry's carbon footprint. The success of this pilot could serve as a model for other energy-intensive manufacturing sectors seeking to lower their emissions.
If successful, this technology could significantly lower the carbon footprint of cement, a material essential to global infrastructure. Communities near cement plants may experience cleaner air and reduced local pollution. However, the transition depends on the availability of affordable clean electricity and the scalability of the batteries. Consumers and construction companies could see slightly higher costs initially, but long-term climate benefits may outweigh these, affecting everyone through more sustainable building practices.
