Cache Energy Innovates with Ancient Cement-Based Thermal Storage Technology
Cache Energy's cement-based thermal storage technology offers a cost-effective solution to energy storage amid rising global energy demands. This innovative system leverages ancient Roman techniques to store thermal energy, potentially transforming industrial heating and residential systems.

Cache Energy has developed a cement-based thermal storage system that utilizes a reversible chemical reaction between quicklime and water, enabling the storage of thermal energy rather than electrical energy. This technology is designed to address the industrial sector's significant energy consumption, which accounts for 20% of global energy use, as reported by the International Energy Agency (IEA).
Successful trials have been reported at Whirlpool's Kitchen-Aid facility in Ohio, and the U.S. Department of Defense is considering its use for maintaining heat in military bases. The technology's simplicity and reliance on readily available materials position it as a competitive alternative to existing heating solutions, although challenges remain in maintaining the structural integrity of cement pellets over numerous cycles.
