A concrete thermal battery could be key to cooling data centers at scale — 150Kw prototype that can withstand up to 500 degrees centigrade is running

Concrete thermal batteries could turn data center waste heat into usable energy

Lehigh researchers develop a thermal battery with 150 kWh storage capacity

The concrete battery withstands temperatures reaching 500°C during thermal storage operations

Engineering researchers at Lehigh University have developed a concrete thermal battery that could help data centers reuse heat removed from computing equipment.

The system stores recovered heat before releasing it for cooling, industrial processes, electricity generation, and other applications requiring thermal energy.

A prototype with 150…
